Combined pressure compensator and cooling unit

Abstract

A container for containing underwater sensors such as sonar transceivers, sonar imaging devices, optical imaging devices, etc, electronic equipment and a cooling liquid for cooling the electronic equipment is connected to a second, variable volume container which acts both as a heat exchanger and as a pressure compensator for compensating the pressure difference between the cooling fluid and the surrounding water or other fluid.

1 . An apparatus, comprising:
 a first container for containing electronic equipment, wherein the electronic equipment is immersed in a liquid coolant, and wherein the apparatus is for immersing in water;   a second container for transferring heat from the liquid coolant to the water, wherein the volume of the second container varies to compensate pressure differences between the liquid coolant and the water.   
   
   
       2 . The apparatus of  claim 1 , wherein the second container is contained within the first container, and wherein the water communicates between the inside of the second container and the outside of the first container. 
   
   
       3 . The apparatus of  claim 2 , further comprising means for flowing the water through the inside of the second container. 
   
   
       4 . The apparatus of  claim 3 , wherein the means for flowing is a scoop. 
   
   
       5 . The apparatus of  claim 3 , wherein the means for flowing is a pump. 
   
   
       6 . The apparatus of  claim 2 , wherein the second container is a pancake shaped container. 
   
   
       7 . The apparatus of  claim 2 , wherein the second container is a bellows. 
   
   
       8 . The apparatus of  claim 1 , wherein the second container is located outside the first container, and wherein the liquid coolant communicates between the inside of the first container and the inside of the second container, and wherein the water outside the first container and the outside of the second container cools the liquid coolant inside the second container. 
   
   
       9 . The apparatus of  claim 8 , further comprising a pump for circulating the liquid coolant between the inside of the first container and the inside of the second container. 
   
   
       10 . The apparatus of  claim 8 , wherein the second container is a pancake shaped container. 
   
   
       11 . The apparatus of  claim 8 , wherein the second container is a bellows. 
   
   
       12 . The apparatus of  claim 1 , wherein the second container is a pancake shaped container. 
   
   
       13 . The apparatus of  claim 1 , wherein the second container is a bellows.
