    • An air cooling unit for a vehicle having a source of energy, such as heat from crankcase oil or transmission oil or a source of electrical power, such as an alternator. The cooling unit is of the absorption type and includes a condenser in series with an evaporator, an absorber and a boiler. The cooling unit is provided with a refrigerant, such as ammonia, and an absorption fluid, such as water. Hydrogen gas can optionally be placed in the cooling unit to move between the evaporator and the absorber to reduce the partial pressure of the refrigerant. A return line in the form of a coil extends from the boiler to an inlet of the absorber to return the absorption fluid to the absorber after the absorption fluid has been separated by heat from the refrigerant gas in the boiler. All of the components of the cooling unit are sized, shaped and located so that the cooling unit provides a compact package capable of being fitted into a relatively small space. A fan can be provided to blow air past the evaporator and through the vehicle for cooling the interior thereof. In one form of the cooling unit, the boiler is provided with heated oil to serve as a heat source, the oil being taken either from the crankcase of the vehicle or from the transmission of the vehicle. In another form of the invention, the boiler includes an electrical resistance heating element in a housing for receiving a mixture of refrigerant and absorption fluid from the absorber, the electrical resistance heating element having means for coupling the same to an electrical energy source, such as the alternator of the vehicle.
    • 一种用于车辆的空气冷却单元,其具有诸如交流发电机之类的来自曲轴箱油或变速器油或电力源的能量源。 冷却单元是吸收型的,并且包括与蒸发器,吸收器和锅炉串联的冷凝器。 冷却单元设置有诸如氨的制冷剂和诸如水的吸收流体。 氢气可以任选地放置在冷却单元中,以在蒸发器和吸收器之间移动以减小制冷剂的分压。 线圈形式的返回线从锅炉延伸到吸收器的入口,在吸收流体已经通过来自锅炉中的制冷剂气体的热分离之后将吸收流体返回到吸收器。 冷却单元的所有部件的尺寸,形状和位置使得冷却单元提供能够装配到较小空间​​中的紧凑型包装。 可以提供风扇以将空气吹过蒸发器并通过车辆冷却其内部。 在冷却单元的一种形式中,锅炉设置有加热的油以用作热源,油从车辆的曲轴箱或车辆的变速器中取出。 在本发明的另一形式中,锅炉包括用于从吸收器接收制冷剂和吸收流体的混合物的壳体中的电阻加热元件,电阻加热元件具有用于将其耦合到电能源的装置,例如 车辆的交流发电机。
