Abstract

The apparatus consists of two condensing chambers 12 and 14 with different temperature levels. Chamber 14 serves as a vapor condenser which keeps coolant 16 from being lost due to evaporation. Chamber 12 contains condenser 18 which acts as a dehumidifier for the incoming air. By proper arrangement of one-way flow valves, chambers 12 and 14 work together to vent the liquid cooling system without losing fluid and to remove moisture from any incoming air. In operation, evaporation or thermal expansion takes place in the cooling system, vapor or a vapor-air mixture tends to escape through valve E and then valve A. The vapor is condensed at condenser 20 and returned to coolant tank 22 by way of valve D.

Evaporation Proof and Moisture Free Venting Apparatus for Liquid Cooling Systems

The apparatus consists of two condensing chambers 12 and 14 with different temperature levels. Chamber 14 serves as a vapor condenser which keeps coolant 16 from being lost due to evaporation. Chamber 12 contains condenser 18 which acts as a dehumidifier for the incoming air. By proper arrangement of one-way flow valves, chambers 12 and 14 work together to vent the liquid cooling system without losing fluid and to remove moisture from any incoming air. In operation, evaporation or thermal expansion takes place in the cooling system, vapor or a vapor-air mixture tends to escape through valve E and then valve A. The vapor is condensed at condenser 20 and returned to coolant tank 22 by way of valve D. If thermal contraction takes place or the liquid level goes down, valve B opens to allow ambient air into the tank via valve C and valve D or even valve
E. The coolant saturation temperature and machine ambient conditions can be adjusted to handle any given requirement. The only conditions are that condenser 20 of chamber 14 has to be kept at a temperature lower than the saturating point of the coolant so that the vapor is condensed. Condenser 18 of chamber 12 must be kept at a temperature lower than that of chamber 14 and tank 22. This can be achieved either by conventional apparatus, or thermoelectric techniques. Thus, air entering the system is sufficiently dry, causing no moisture cond...
