Description
Description A COOLING DEVICE
[0001] The present invention relates to a cooling device, the condenser of which is effectively cooled.
[0002] In cooling devices, for example refrigerators, heat energy is discharged outside from the condenser in the refrigerant cycle by natural or forced heat convection methods. The condensers operating with natural heat convection are generally used in conventional refrigerators whereas the condensers operating with forced heat convection are used in no-frost type refrigerators. The compressor and the condenser in no-frost refrigerators usually operate in a compartment in the lower part of the refrigerator body and coil type condensers are used. Heat transfer from the condenser to the outside has to be accelerated in order to increase the efficiency of the refrigerant system therefore heat has to be removed with forced convection by means of a Ian blowing air over the condenser. In state of the art, the air aspirated from outside by means of a Ian is generally passed over the condenser and directed towards the compressor. High air flow rate is required to cool the condenser sufficiently and since the cooling Ian is operated at high speed, this results in an increase in noise. The air that is blown over the condenser leaves the condenser because of withdrawal of air and cannot cool the compressor sufficiently.
[0003] In the European patent document no. EP1475590, a component compartment
(machinery compartment) at the lower part of the refrigerator main body has a rear opening, which is closed by a cover and the cover is provided with air inlets and air outlets that are spaced apart from each other. A compressor and a condenser are provided in the component compartment respectively behind the air inlets and the air outlets. A Ian is provided between the condenser and the air outlets to expel air within the component compartment through the air outlets after being passed over the compressor and the condenser.
[0004] In the United Slates of America patent document no. US5592829, a Ian disposed between the compressor and the condenser sucks in the air from outside and directs it over the compressor.
[0005] In the United Slates of America patent document no. US5428973, in a refrigerator, a zigzag shaped air passage duct is described which is connected to the machine compartment, containing a wire and tube condenser operating therein where a cooling air aspirated by a Ian flows across over the condenser.
[0006] The aim of the present invention is the realization of a cooling device wherein the condenser is cooled effectively and the noise level is decreased.
[0007] The cooling device realized in order to attain the aim of the present invention is explicated in the claims.
[0008] In the cooling device of the present invention, the condenser is disposed inside a condenser casing and air is blown towards the condenser casing by means of a fen. The condenser casing is constituted of an inner body and an outer body disposed one within the other in horizontal position, between the ian and the compressor, such that the air blown by the ian will pass therebetween. A gap is provided between the inner body and the outer body that will allow air to flow therebetween and the condenser is disposed in this gap.
[0009] A flow guide is provided in the condenser casing, on the end of the inner body feeing the fen, providing the air blown by the fen to be distributed from the center towards the sides, to be directed to the gap between the inner body and the outer body. The flow guide closes the part of the inner body feeing the fen, thus preventing or at least limiting the air blown by the fen to enter into the nonfunctional empty region at the inner portion of the inner body. The flow guide has a convex configuration that extends from the inner body towards the fen.
[0010] In an embodiment of the present invention, the condenser casing is male of a cylindrical shaped inner body and outer body thus with the gap therebetween having a ring shaped cross-section and the condenser, formed of flow tubes coiled in helical shape is disposed within this gap.
[0011] In another embodiment of the present invention, a flange is provided in the condenser casing that is integrated to the outer body or produced as a single piece with the outer body, having a bell-mouth shaped configuration that widens as it extends towards the fen. The flange maintains the air blown by the fen to be collected and directed towards the gap between the inner body and outer body.
[0012] In another embodiment of the present invention, supports that extend between the inner body and the outer body are used for attaching the inner body and the outer body constituting the condenser casing by being centered one within the other. By means of the supports, the gap between the inner body and outer body is preserved and the air blown by the fen is provided to leave from the side of the condenser casing feeing the compressor.
[0013] By means of the condenser casing, the backflow of the air blown on the condenser is prevented and the heat energy expelled outside is increased by maintaining most of the
blown air to get in contact with the condenser. Consequently, cooling of the condenser is accomplished by a lower air flow rate than conventional implementations, reduced ian rotation speeds are sufficient for lower air flow rates and thus the noise level can be decreased.

[0019] The cooling device (1), for example a refrigerator, comprises a compressor (2) for actuating the refrigerant cycle, a condenser (3) for condensing the refrigerant fluid, a compartment (4) wherein the compressor (2) and the condenser (3) are disposed, and a ian (5) situated inside the compartment (4) for cooling the condenser (3) and the compressor (2) by blowing air over them.
[0020] The cooling device (1) of the present invention comprises a condenser casing (6) that supports the condenser (3), directing the air blown by the ian (5) directly towards the condenser (3) and providing to direct the air leaving the condenser (3) to the compressor (2), thus cooling the condenser (3) effectively by forced convection.
[0021] The condenser casing (6) comprises,
- an inner body (7) and an outer body (8) disposed one within the other such
that the air blown by the fan (5) will pass therebetween, having a gap (B) in between that will allow air to flow therethrough and a condenser (3) disposed in this gap (B), and - a flow guide (11) disposed on the side of the inner body (7) facing the fan (5), providing the air blown by the fan (5) to be distributed from the center towards the sides, to be directed to the gap (B).
[0022] In the preferred embodiment of the present invention, the flow guide (11) closes the end of the inner body (7) facing the fan (5), thus the air blown by the fan (5) is prevented from entering into the inner portion of the inner body (7). The air blown by the fan (5) particularly to places at the vicinity of the center is directed towards the gap (B) by means of the flow guide (11) and affects on the condenser (3) disposed in the gap (B). The flow guide (11) is configured convexly towards the fan (5) thus provides air to be diffused without forming a resistance thereto.
[0023] In another embodiment of the present invention, the inner body (7) and the outer body (8) are configured cylindrically and the gap (B) in between has a ring shaped cross-section. The condenser (3) is dimensioned to be disposed in the gap (B) and cannot be viewed after being disposed in the gap (B). In this embodiment of the present invention, the condenser (3) is configured by coiling the flow tubes helically around a cylindrical surface such that a hollow cylinder is formed. In the conventional technique, the air blown by the fan (5) also sweeps the said hollow portion at the center of the same type of cylindrical helical condensers (3). However in the embodiment of the present invention, passing of air through the hollow portion at the center of the cylindrical helical condenser (3) is prevented by the flow guide (11), furthermore air that flows with a higher speed in a narrow gap (B) contacts with the flow tubes arranged only at the side portions of the condenser (3) by means of the flow guide (11) and thus effective cooling of the condenser (3) flow tubes is accomplished. [0024] The air blown by the fan (5) towards the condenser casing (6) is directed to between the inner body (7) and the outer body (8) by means of the flow guide (11) disposed on the side of the inner body (7) facing the fan (5). The air prevented from entering the empty portion at the center of the inner body (7) and flowing through the gap (B) between the inner body (7) and the outer body (8), passes over the flow tubes of the condenser (3) disposed in this gap (B) and the condenser (3) is cooled effectively by forced convection. The air that passes through the condenser casing (6) sweeping the condenser (3) leaves the condenser casing (6) from the side facing the compressor (2), heading towards and cooling the compressor (2).
[0025] In another embodiment of the present invention, a condenser (3) called "wire on tube" is used in the cooling device (1). The condenser (3) is composed of flow tubes where through refrigerant fluid flows and wires are arranged on the flow tubes that increase heat transfer and keep the flow tubes in a rigid configuration (Hgure 3).
[0026] In another embodiment of the present invention, the condenser casing (6) is disposed between the fen (5) and the compressor (2) in a horizontal position, thus the air blown by the ian (5) can easily enter from one side of the condenser casing (6) leaves from the other side.
[0027] In another embodiment of the present invention, the condenser casing (6) comprises a flange (10) that is disposed on the side of the outer body (8) lacing the fen (5) that provides the air blown by the fen (5) to be collected and directed towards the gap (B) between the inner body (7) and outer body (8). The flange (10) is integrated to the outer body (8) or is produced as a single piece with the outer body (8) and is configured in a bell-mouth shape that widens as it extends towards the fen (5).
[0028] The air blown by the fen (5) towards the condenser casing (6) is directed towards between the inner body (7) and outer body (8) by means of the flow guide (11) disposed on the side of the inner body (7) feeing the fen (5) and the flange (10) disposed on the side of the outer body (8) feeing the fen (5). As the air flows through the gap (B) between the inner body (7) and the outer body (8), it passes over the flow tubes and the wires or plates attached on the flow tubes of the condenser (3) situated in this gap (B) and the effective cooling of the condenser (3) by forced convection is provided. The air that passes through the condenser casing (6) sweeping the condenser (3), leaves the condenser casing (6) from the side feeing the compressor (2) and heads towards the compressor (2) for cooling it.
[0029] In another embodiment of the present invention, the condenser casing (6) comprises one or more supports (9) that extend between the inner body (7) and the outer body (8) and that attach the inner body (7) and the outer body (8) by centering one within the other. By means of the supports (9), the gap (B) between the inner body (7) and the outer body (8) is preserved and the air blown by the fen (5) is provided to leave from the side of the condenser (3) casing feeing the compressor (2).
[0030] In another embodiment of the present invention, the condenser (3) flow tubes are coiled on the outer surfece of the inner body (7). Accordingly, the flow tubes of particularly the coil type condenser (3) are not required to be coiled somewhere else and arranged in the condenser casing (6), the flow tubes are directly wrapped around the inner body (7) thus providing convenience of production.
[0031] In another embodiment of the present invention, the condenser (3) is suspended from the supports (9) between the inner body (7) and the outer body (8) and does not contact either the inner body (7) or the outer body (8). In this embodiment, the air sent to the gap (B) between the inner body (7) and the outer body (8) by the ian (5) contacts the flow tubes of the condenser (3) both from above and below thus the condenser (3) is cooled effectively.
[0032] In another embodiment of the present invention, the ian (5) used in the cooling device (1) is of the axial type.
[0033] In another embodiment of the present invention, the inner body (7), the outer body (8), the flange (10) constituting the condenser casing (6) and the flow guide (11) is male of plastic material to enhance cooling of the condenser (3).
[0034] By means of the condenser casing (6) of the present invention, the backflow of the air blown on the condenser (3) by the ian (5) is prevented and the cooling performance of the cooling device (1) is increased by a greater amount of the blown air getting in contact with the condenser (3) hence increasing the heat energy expelled outside. The desired heat transfer is accomplished by a lower flow rate of air than conventional implementations. Since a lower air flow rate is sufficient, the ian (5) operates with lower rotation speeds thus the air flow conducive noise generated by the ian (5) can be reduced.
