　図２及び図３は、本発明の実施形態の温調装置１００の説明図である。図２は温調装置１００の上面透視図、図３は温調装置１００の側面透視図である。 2 and 3 are explanatory diagrams of the temperature control device 100 according to the embodiment of the present invention. FIG. 2 is a top perspective view of the temperature control device 100, and FIG. 3 is a side perspective view of the temperature control device 100.

　温調装置１００は、ケース１０内に、送風機２０、加熱用熱交換器３０（第２熱交換器）、冷却用熱交換器４０（第１熱交換器）が備えられて構成される。 The temperature control device 100 includes a blower 20, a heating heat exchanger 30 (second heat exchanger), and a cooling heat exchanger 40 (first heat exchanger) in a case 10.

　送風機２０は、回転する羽根車（ファン）２１により、上方から吸い込んだ空気を、ファン２１の回転による遠心力により、ファン２１の回転軸と直交する方向に設けられる吹出口２４に向かって送風する遠心送風機である。本実施形態の送風機２０は、ファン２１の回転軸方向に扁平された構造を有する。 The blower 20 blows air sucked from above by a rotating impeller (fan) 21 toward an outlet 24 provided in a direction perpendicular to the rotation axis of the fan 21 by centrifugal force generated by the rotation of the fan 21. Centrifugal blower. The blower 20 of this embodiment has a structure flattened in the direction of the rotation axis of the fan 21.

　送風機２０は、回転による遠心力により径方向に空気を送出するファン２１と、ファン２１の空気の送出方向を送風の出口となる吹出口２４へと送るカバー２２とから構成される。送風機２０は、上方、すなわち、ファン２１の回転軸方向からバッテリケース２００内の空気を吸い込み、ファン２１の径方向へと空気を送出する。送出された空気は、カバー２２の形状に沿ってファン２１の回転軸と直行する方向に設けられる吹出口２４から、加熱用熱交換器３０及び冷却用熱交換器４０に向けて送風される。 The blower 20 includes a fan 21 that sends air in a radial direction by centrifugal force due to rotation, and a cover 22 that sends the air sending direction of the fan 21 to a blower outlet 24 that serves as a blower outlet. The blower 20 sucks air in the battery case 200 from above, that is, from the direction of the rotation axis of the fan 21, and sends the air in the radial direction of the fan 21. The delivered air is blown toward the heating heat exchanger 30 and the cooling heat exchanger 40 from the outlet 24 provided in a direction perpendicular to the rotation axis of the fan 21 along the shape of the cover 22.

　加熱用熱交換器３０は、例えば電力により加熱されるＰＴＣヒータ等の加熱部が備えられる外縁部３１と、外縁部３１に囲繞され、送風機２０からの送風が通過する熱交換部３２とを備える。加熱用熱交換部３０では、送風機２０からの送風が熱交換部３２を通過することにより、送風が加熱される。加熱用熱交換器３０は図４で詳述する。 The heating heat exchanger 30 includes, for example, an outer edge portion 31 provided with a heating portion such as a PTC heater that is heated by electric power, and a heat exchange portion 32 that is surrounded by the outer edge portion 31 and through which air blown from the blower 20 passes. . In the heating heat exchanging unit 30, the air from the blower 20 passes through the heat exchanging unit 32, whereby the air is heated. The heat exchanger 30 for heating will be described in detail with reference to FIG.

　冷却用熱交換器４０は、冷凍サイクルシステムの一部として構成される。冷却用熱交換器４０は、冷媒が通過する流路へと送風が通過する熱交換部４４を備える。冷却用熱交換部４０では、熱交換部４４に流通する低温の冷媒と、熱交換部４４を通過する送風とで熱交換が行われることにより、送風機２０からの送風を冷却する。 The heat exchanger for cooling 40 is configured as a part of the refrigeration cycle system. The cooling heat exchanger 40 includes a heat exchanging unit 44 through which air flows to the flow path through which the refrigerant passes. In the cooling heat exchanging unit 40, the air blown from the blower 20 is cooled by performing heat exchange between the low-temperature refrigerant flowing through the heat exchanging unit 44 and the air blown through the heat exchanging unit 44.

　制御装置１６０は、バッテリケース２００の内部の空気の温度を検出し、検出された温度に基づいて温調装置１００から送風される空気の温度を決定する。温調装置１００は、制御装置１６０の決定に基づいて、加熱用熱交換器３０及び冷却用熱交換器４０による温度を制御し、送風機２０によって送風を行う。 The control device 160 detects the temperature of the air inside the battery case 200, and determines the temperature of the air blown from the temperature adjustment device 100 based on the detected temperature. The temperature control device 100 controls the temperature by the heating heat exchanger 30 and the cooling heat exchanger 40 based on the determination of the control device 160 and blows air by the blower 20.

　送風機２０の送風は、加熱用熱交換器３０を通過する。バッテリケース２００内に加熱した空気を送風する場合は、加熱用熱交換器３０の加熱部３１を加熱させて、通過する送風との間で熱交換を行い、送風を加熱する。送風を加熱しない場合は加熱部３１を加熱させず、送風はそのまま加熱用熱交換器３０を通過する。 Blowing of the blower 20 passes through the heat exchanger 30 for heating. When the heated air is blown into the battery case 200, the heating unit 31 of the heating heat exchanger 30 is heated to exchange heat with the passing air to heat the air. When the air is not heated, the heating unit 31 is not heated, and the air passes through the heating heat exchanger 30 as it is.

　加熱用熱交換器３０を通過した送風は、冷却用熱交換器４０を通過する。バッテリケース２００内に冷却した空気を送風する場合は、冷却用熱交換器４０を通過する冷媒の温度を低下させ、送風を冷却する。冷却を行わない場合は冷却用熱交換器４０の冷却を抑制させ、送風がそのまま送風口１６からバッテリケース２００へと送風される。 The air that has passed through the heat exchanger 30 for heating passes through the heat exchanger 40 for cooling. When the cooled air is blown into the battery case 200, the temperature of the refrigerant passing through the cooling heat exchanger 40 is lowered to cool the blown air. When cooling is not performed, cooling of the cooling heat exchanger 40 is suppressed, and air is blown directly from the blower opening 16 to the battery case 200.

　このようにして、温調装置１００により温調された空気が、送風口１６からバッテリケース２００の内部に送られる。 In this way, the air temperature-controlled by the temperature control device 100 is sent from the blower port 16 to the inside of the battery case 200.

　冷却用熱交換器４０には、冷媒を冷却用熱交換器４０に流入させる入口側冷媒配管４１と、冷媒を冷却用熱交換器４０から流出させる出口側冷媒配管４２とが接続される。入口側冷媒配管４１と出口側冷媒配管４２との間には、冷媒を減圧させて気化を促し、また冷媒流量を最適に調節する膨張弁４３が備えられる。 The cooling heat exchanger 40 is connected to an inlet side refrigerant pipe 41 that allows the refrigerant to flow into the cooling heat exchanger 40 and an outlet side refrigerant pipe 42 that causes the refrigerant to flow out of the cooling heat exchanger 40. Between the inlet side refrigerant pipe 41 and the outlet side refrigerant pipe 42, there is provided an expansion valve 43 that depressurizes the refrigerant to promote vaporization and optimally adjusts the refrigerant flow rate.

　入口側冷媒配管４１と出口側冷媒配管４２とは、フランジ部４５に接続される。フランジ部４５は、温調装置１００の内部に備えられる入口側冷媒配管４１及び出口側冷媒配管４２を温調装置１００の外部の配管と分離可能に接続するコネクタの役割を有する。フランジ部４５は、例えばバッテリケース２００に形成される接続部に配置され、バッテリケース２００の外部に備えられる冷凍サイクルシステム（凝縮器、圧縮器等）へと配管等により接続される。 The inlet side refrigerant pipe 41 and the outlet side refrigerant pipe 42 are connected to the flange portion 45. The flange 45 has a role of a connector that detachably connects the inlet-side refrigerant pipe 41 and the outlet-side refrigerant pipe 42 provided in the temperature control apparatus 100 with a pipe outside the temperature control apparatus 100. The flange portion 45 is disposed, for example, at a connection portion formed in the battery case 200 and is connected to a refrigeration cycle system (condenser, compressor, etc.) provided outside the battery case 200 by piping or the like.

　膨張弁４３は、入口側冷媒配管４１に小径の流路を形成して冷媒を霧状とし、冷却用熱交換器４０内部で媒体を気化させることにより冷却用熱交換器４０を冷却する。膨張弁４３は、冷却用熱交換器４０を通過して出口側冷媒配管４２を流通する媒体の温度により入口側冷媒配管４１を流通する冷媒の量を調節する。 The expansion valve 43 cools the cooling heat exchanger 40 by forming a small-diameter channel in the inlet-side refrigerant pipe 41 to make the refrigerant mist and evaporating the medium inside the cooling heat exchanger 40. The expansion valve 43 adjusts the amount of refrigerant flowing through the inlet side refrigerant pipe 41 according to the temperature of the medium passing through the cooling heat exchanger 40 and flowing through the outlet side refrigerant pipe 42.

　入口側冷媒配管４１及び出口側冷媒配管４２は、上方から観察した場合（図２参照）、吹出口２４の中心線に対してファン２１とは逆側に配置される。送風機２０は、吹出口２４の幅方向の中心線に対してファン２１の回転軸の中心がオフセットされて配置されている。このような構造において、送風機２０の吹出口２４の幅方向の中心と加熱用熱交換器３０及び冷却用熱交換器４０の幅方向の中心とを一致させた場合は、これらの幅方向の中心線に対して、ファン２１の構造がオフセットされて配置される。この場合、これら幅方向の中心線に対して、ファン２１の構造と逆側に空間が発生する。バッテリモジュール１５０や制御装置１６０等は概ね矩形形状の構造であるため、バッテリケース２００の内部のスペース効率を向上させるためには、温調装置１００についても矩形の構造が望ましい。 The inlet-side refrigerant pipe 41 and the outlet-side refrigerant pipe 42 are arranged on the side opposite to the fan 21 with respect to the center line of the outlet 24 when observed from above (see FIG. 2). The blower 20 is disposed such that the center of the rotation axis of the fan 21 is offset with respect to the center line in the width direction of the air outlet 24. In such a structure, when the center in the width direction of the air outlet 24 of the blower 20 and the center in the width direction of the heat exchanger 30 for heating and the heat exchanger 40 for cooling are matched, the centers in the width direction of these The structure of the fan 21 is offset with respect to the line. In this case, a space is generated on the opposite side to the structure of the fan 21 with respect to the center line in the width direction. Since the battery module 150, the control device 160, and the like have a generally rectangular structure, in order to improve the space efficiency inside the battery case 200, the temperature control device 100 also preferably has a rectangular structure.

　そこで、本実施形態の温調装置１００は、入口側冷媒配管４１及び出口側冷媒配管４２を、吹出口２４の中心線に対してファン２１とは逆側に配置することにより、温調装置１００の全体の構造を矩形の形状に収めることができるとともに、厚さ方向（図３参照）にも小型化することができる。 Therefore, the temperature control apparatus 100 according to the present embodiment arranges the inlet-side refrigerant pipe 41 and the outlet-side refrigerant pipe 42 on the side opposite to the fan 21 with respect to the center line of the outlet 24, whereby the temperature control apparatus 100. The entire structure can be accommodated in a rectangular shape and can be reduced in the thickness direction (see FIG. 3).

　なお、入口側冷媒配管４１及び出口側冷媒配管４２を配置する箇所に、送風機２０及び加熱用熱交換器３０のハーネスを配置してもよい。 In addition, you may arrange | position the harness of the air blower 20 and the heat exchanger 30 for a heating in the location which arrange | positions the inlet side refrigerant | coolant piping 41 and the outlet side refrigerant | coolant piping 42. FIG.

　図３を参照すると、ケース１０の底面側には、凝縮水を貯留する貯留部１１が形成される。貯留部１１は、冷却用熱交換器４０の底面側から風下側にかけて形成されている。冷却用熱交換器４０は、低温の冷媒が流通するときに凝縮水が発生する。凝縮水は重力に従って、冷却用熱交換器４０の底面側の貯留部１１へと滴下し、凝縮水が貯留部１１に貯留される。 Referring to FIG. 3, a storage part 11 for storing condensed water is formed on the bottom side of the case 10. The storage unit 11 is formed from the bottom surface side to the leeward side of the cooling heat exchanger 40. The cooling heat exchanger 40 generates condensed water when a low-temperature refrigerant flows. Condensed water drops according to gravity to the storage part 11 on the bottom surface side of the cooling heat exchanger 40, and the condensed water is stored in the storage part 11.

　冷却用熱交換器４０の冷媒が流通する入口側冷媒配管４１及び出口側冷媒配管４２の表面にも凝縮水が発生する。本実施形態では、入口側冷媒配管４１及び出口側冷媒配管４２の底面側に、貯留部１１へと凝縮水を流下させるように、貯留部１１へと傾斜を有する溝部１２を形成した。入口側冷媒配管４１及び出口側冷媒配管４２に発生した凝縮水は溝部１２へと滴下した後、溝部１２の傾斜面を流れて貯留部１１へと貯留される。 Condensed water is also generated on the surfaces of the inlet side refrigerant pipe 41 and the outlet side refrigerant pipe 42 through which the refrigerant of the cooling heat exchanger 40 flows. In the present embodiment, the groove portion 12 having an inclination toward the storage portion 11 is formed on the bottom surface side of the inlet side refrigerant pipe 41 and the outlet side refrigerant piping 42 so that the condensed water flows down to the storage portion 11. Condensed water generated in the inlet-side refrigerant pipe 41 and the outlet-side refrigerant pipe 42 is dropped into the groove portion 12, and then flows through the inclined surface of the groove portion 12 and is stored in the storage portion 11.

　貯留部１１に貯留された凝縮水は、温調装置１００による加熱によって蒸発させてもよいし、逆止弁等を設けて車外に排出するようにしてもよい。 The condensed water stored in the storage unit 11 may be evaporated by heating with the temperature control device 100, or may be discharged outside the vehicle by providing a check valve or the like.

　このように、温調装置１００の内部には凝縮水が貯留されるので、振動等により加熱用熱交換器３０における漏電を防止するため、電力により動作する加熱用熱交換器３０を絶縁構造とする。 Thus, since the condensed water is stored inside the temperature control device 100, the heating heat exchanger 30 operated by electric power has an insulating structure in order to prevent electric leakage in the heating heat exchanger 30 due to vibration or the like. To do.

A heating unit is provided above the outer edge portion 31, and a harness 33 that supplies power to the heating unit is connected thereto.

　加熱用熱交換器３０において、外縁部３１と、外縁部３１に電力を供給するハーネス３３に絶縁性の塗料等を塗布することによって、これらを絶縁構造とする。送風機２０の送風とで熱交換を行う熱交換部３２は、熱交換効率を向上させるため表面を金属表面のままとする。同様に、送風機２０のハーネス等の部位を絶縁構造としてもよい。 In the heat exchanger 30 for heating, an insulating paint or the like is applied to the outer edge portion 31 and the harness 33 that supplies electric power to the outer edge portion 31, thereby forming an insulating structure. The heat exchanging unit 32 that performs heat exchange with the blower of the blower 20 keeps the surface as a metal surface in order to improve heat exchange efficiency. Similarly, a part such as a harness of the blower 20 may have an insulating structure.

The center of the shaft is offset with respect to the center line in the width direction, and it becomes possible to arrange a pipe, a harness, and the like in the space formed by the offset, and the space efficiency is improved, thereby downsizing the temperature adjustment device 100. be able to.

　さらに、送風機２０の吹出口２４と、加熱用熱交換器３０と、冷却用熱交換器４０とが幅方向の中心を略同一となるように配置したので、加熱用熱交換器３０と冷却用熱交換器４０とに対して均一な送風ができ、熱交換性能の低下を防止できる。 Furthermore, since the blower outlet 24 of the blower 20, the heat exchanger 30 for heating, and the heat exchanger 40 for cooling are arranged so that the centers in the width direction are substantially the same, the heat exchanger 30 for heating and the cooling heat exchanger 30 are arranged. Uniform ventilation can be performed with respect to the heat exchanger 40, and deterioration in heat exchange performance can be prevented.

　本実施形態の加熱用熱交換器３０は、加熱部３１として、電力により加熱するＰＴＣヒータ等の電気ヒータを用いた。このような構成により、加熱用熱交換器３０がハーネス等の電気配線のみで済み、熱媒体等の配管を配置する必要がなくなるので、レイアウトの自由度が向上し、温調装置１００を小型化することができる。 In the heating heat exchanger 30 of the present embodiment, an electric heater such as a PTC heater that is heated by electric power is used as the heating unit 31.

Thereby, the influence by the condensed water which generate | occur | produces in the heat exchanger 40 for cooling can be prevented.

　本実施形態は、羽根車の回転により送風を行う遠心式送風機としての送風機２０と、送風された空気と冷媒とを熱交換する第１熱交換器としての冷却用熱交換器４０と、を備え、送風機２０の送風の温度を調節する温調装置１００であって、羽根車の回転軸は、冷却用熱交換器４０の幅方向中心に対して、幅方向の一方側にオフセットして配置され、冷却熱交換器４０は、幅方向の他方側から冷媒が流通する冷媒配管（入口側冷媒配管４１及び出口側冷媒配管４２）と接続されることを特徴とする。 The present embodiment includes a blower 20 as a centrifugal blower that blows air by rotation of an impeller, and a cooling heat exchanger 40 as a first heat exchanger that exchanges heat between the blown air and a refrigerant. The temperature control device 100 adjusts the temperature of the air blown by the blower 20, and the rotation shaft of the impeller is arranged offset to one side in the width direction with respect to the width direction center of the cooling heat exchanger 40. The cooling heat exchanger 40 is connected to refrigerant pipes (inlet side refrigerant pipe 41 and outlet side refrigerant pipe 42) through which refrigerant flows from the other side in the width direction.

　本実施形態によると、羽根車の回転軸は、加熱用熱交換器４０に対して、幅方向の一方側にオフセットして配置され、加熱用熱交換器４０は、幅方向の他方側から冷媒が流通する冷媒配管と接続されるので、送風機２０の羽根車（ファン）の回転軸中心が、加熱用熱交換器４０の幅方向の中心に対してオフセットされる。オフセットにより生成される空間に配管やハーネス等を配置することが可能となり、スペース効率が向上する。 According to the present embodiment, the rotating shaft of the impeller is arranged offset to one side in the width direction with respect to the heating heat exchanger 40, and the heating heat exchanger 40 is refrigerant from the other side in the width direction. Therefore, the rotation shaft center of the impeller (fan) of the blower 20 is offset with respect to the center of the heating heat exchanger 40 in the width direction. Piping and harnesses can be arranged in the space generated by the offset, and space efficiency is improved.

　上記実施形態では、車両に搭載されるバッテリモジュール１５０の温度を調節する温調装置１００について説明したが、これに限られるものではない。バッテリモジュール１５０以外の構成、例えば車両用のエアコンユニットについても同様に適用可能である。 In the above embodiment, the temperature control apparatus 100 that adjusts the temperature of the battery module 150 mounted on the vehicle has been described, but the present invention is not limited to this.
