具体实施方式 detailed description
下面结合附图和具体实施方式对本实用新型作进一步说明。 The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
如图 1所示， 电热式水介质取暖器， 包括散热片 1、 电加热棒 2、 控制器 3、 呼气装置 4、 吸气装置 5。 电加热棒设置在散热片下部。 电加热棒与散热片外的控制器相连接， 电加热棒 2 及控制器 3安装在散热片下部。 As shown in Fig. 1, the electrothermal water medium heater includes a heat sink 1, an electric heating rod 2, a controller 3, an exhalation device 4, and a suction device 5. The electric heating rod is placed under the heat sink. The electric heating rod is connected to a controller outside the heat sink, and the electric heating rod 2 and the controller 3 are mounted on the lower portion of the heat sink.
散热片上部安装有呼、 吸气装置 4、 5 (或者可以称为压力调节装置）。 散热片内的最高 水位低于呼气装置和吸气装置。 散热片 1加注了水但上部留有一定量空气。 当散热片内上部 的压力大于呼气装置的预设压力时， 呼气装置打开， 向外排出热空气； 待散热片内上部的压 力等于呼气装置的预设压力， 呼气装置停止向外排出热空气； 当散热片内上部的压力小于呼 气装置的预设压力时， 呼气装置关闭。 当散热片内上部的压力小于吸气装置的预设压力时， 吸气装置打开， 外部空气进入散热片内； 待散热片内上部的压力大于吸气装置的预设压力， 吸气装置关闭。 The upper part of the heat sink is equipped with a breathing and suction device 4, 5 (or may be referred to as a pressure regulating device). The highest water level in the heat sink is lower than the exhalation device and the suction device. The heat sink 1 is filled with water but has a certain amount of air in the upper part. When the pressure in the upper part of the heat sink is greater than the preset pressure of the exhalation device, the exhalation device is opened to discharge the hot air outward; the pressure in the upper part of the heat sink is equal to the preset pressure of the exhalation device, and the exhalation device stops outward Exhaust hot air; when the pressure in the upper part of the fin is less than the preset pressure of the exhalation device, the exhalation device is turned off. When the pressure in the upper part of the heat sink is less than the preset pressure of the air suction device, the air suction device is opened, and the outside air enters the heat sink; the pressure in the upper portion of the heat sink is greater than the preset pressure of the air suction device, and the air suction device is closed.
在散热片的上部安装的呼吸装置 （或者称为压力调节装置） 可以是二个独立的呼气装置 和吸气装置， 也可以是一体的呼吸装置。 The breathing apparatus (or pressure regulating device) installed on the upper portion of the heat sink may be two independent exhaling devices and aspirating devices, or may be an integrated breathing device.
呼气装置为单向压力调节阀结构。 The exhalation device is a one-way pressure regulating valve structure.
吸气装置为单向压力调节阀结构。 The suction device is a one-way pressure regulating valve structure.
本实用新型由于在散热片的上部安装有呼吸装置（或者称为压力调节装置）， 电热式水介 质取暖器在刚开机运行时段， 随着温度升高， 散热片水道的上部空气压力会相应升高， 当内 部压力大于呼气装置设置的安全压力时， 呼气装置开始打开， 向外排出热空气， 这样就保证 了取暖器水道内部维持在设定的安全压力状态。 由于水和空气的热膨胀与温度成正比， 当取 暖器达到正常工作温度后， 电热棒产生的热量与取暖器散发的热量达到了相对的平衡状态， 水道内部压力也会达到工作温度下相对平衡， 这时呼气装置就会停止向外排出热空气。 当散 热片内上部的压力小于呼气装置的预设压力时， 呼气装置关闭。 当取暖器关闭停止运行， 水 温冷却后， 随着水道内压力降低至设定的负压时， 吸气装置打开， 使得水道内部可以补充前 面呼气时排出的空气， 这样取暖器水道内部的压力又会慢慢达到非工作温度 （或者说环境温 度） 下的相对平衡， 待散热片内上部的压力大于吸气装置的预设压力时， 吸气装置关闭， 在 以后的整个关闭停止运行时段， 这种取暖器的水道一直是密封状态。 对于不同材质和规格的散热片， 可以依据散热片安全工作温度和完全静音这二个条件对 本实用新型的呼吸装置进行安全压力的合理调整， 以确保本实用新型电热式水介质取暖器在 合理的工作温度， 完全静音和安全压力下运行。 In the utility model, a breathing device (also referred to as a pressure regulating device) is installed on the upper part of the heat sink, and the upper air pressure of the heat sink water channel rises correspondingly as the temperature rises during the start-up operation period of the electric heating type water medium heater. High, when the internal pressure is greater than the safety pressure set by the exhalation device, the exhalation device starts to open and discharges the hot air outward, thus ensuring that the interior of the heater water channel is maintained at a set safe pressure state. Since the thermal expansion of water and air is proportional to the temperature, when the heater reaches the normal working temperature, the heat generated by the electric heating rod and the heat dissipated by the heater are in a relatively balanced state, and the internal pressure of the water channel is also relatively balanced at the working temperature. At this time, the exhalation device will stop discharging hot air to the outside. When the pressure in the upper portion of the fin is less than the preset pressure of the exhalation device, the exhalation device is turned off. When the heater is turned off and stops, after the water temperature is cooled, as the pressure in the water channel drops to the set negative pressure, the suction device is opened, so that the inside of the water channel can replenish the air discharged from the previous exhalation, so that the pressure inside the heater channel It will slowly reach the relative balance under the non-operating temperature (or ambient temperature). When the pressure in the upper part of the heat sink is greater than the preset pressure of the suction device, the suction device is closed, and in the subsequent shutdown and stop operation period, The water channel of this heater is always sealed. For the heat sinks of different materials and specifications, the safe pressure of the breathing apparatus of the present invention can be reasonably adjusted according to the safe working temperature of the heat sink and the completely silent condition, so as to ensure that the electrothermal water medium heater of the utility model is reasonable. Operating temperature, fully silent and safe to operate under pressure.
