Thermosiphonic oil cooler for refrigerating chiller

一种在致冷器中的润滑油的冷却，该冷却是通过使热油与源自致冷器冷凝器(14)并又返回其中的液态致冷剂进行热交换接触而实现的。在一个油冷却热交换器(36)中进行的从油向致冷剂的热量的排放使致冷剂蒸发，从而在从冷凝器(14)流出的致冷剂与油冷却热交换器(36)中的下游的致冷剂之间产生密度差。该密度差引发了持续地维持致冷剂流过热交换器(36)以进行冷却的作用。 Oil cooling is accomplished in a refrigeration chiller by flowing hot oil into heat exchange contact with liquid refrigerant which is sourced from the chiller's condenser and returned thereto. The rejection of heat from the oil to the refrigerant in an oil-cooling heat exchanger causes vaporization of the refrigerant and, in turn, creates a density difference in the refrigerant flowing from the condenser and refrigerant in and downstream of the oil-cooling heat exchanger. This density difference is responsible for inducing and maintaining refrigerant flow through the heat exchanger for oil cooling purposes.
