Heating exchange chamber for liquid state cooling fluid

Abstract

A heat exchange chamber for liquid state cooling fluid is provided, which comprises a thermal dissipation device, and the thermal dissipation device sites in a cavity of the heat exchange chamber for liquid state cooling fluid. The thermal dissipation device comprises a plate and a plurality of heat dissipating fins formed on the plate, and the thermal dissipation device comprises at least one groove. After flowing through the heat dissipating fins, partial cooling fluid absorbs the heat of the heat dissipating fins and gasifies to bubbles. The design of the groove could discharge the bubbles trapped between heat dissipating fins helpfully and improve the efficiency of heat dissipation.

1 . A heat exchange chamber for liquid state cooling fluid, comprising:
 a casing, configured with a cavity, an inlet and an outlet in a manner that the inlet is provided for allowing a cooling fluid to flow into the cavity and the outlet is provided for allowing the cooling fluid to flow out of the cavity; and   a thermal dissipation device, configured with a plate, a plurality of heat dissipating fins formed on the plate, and at least one groove configured for discharge bubbles resulting from the gasification of the cooling fluid inside the heat exchange chamber that are trapped between heat dissipating fins.   
     
     
         2 . The heat exchange chamber of  claim 1 , wherein each of the at least one groove is substantially a recess formed from the height variation of the plural heat dissipating fins. 
     
     
         3 . The heat exchange chamber of  claim 1 , wherein each of the at least one groove is substantially a gap enclosed between any two neighboring heat dissipating fins of the plural heat dissipating fins that are coplanar disposed. 
     
     
         4 . The heat exchange chamber of  claim 1 , wherein each of the at least one groove is formed extending in a direction perpendicular to a flowing direction of the cooling fluid inside the cavity. 
     
     
         5 . The heat exchange chamber of  claim 1 , wherein the length of the at least one groove is not larger than the length of the thermal dissipation device measured in a direction perpendicular to the flowing direction. 
     
     
         6 . The heat exchange chamber of  claim 1 , wherein the diameter of the outlet is larger than that of the inlet. 
     
     
         7 . The heat exchange chamber of  claim 1 , wherein the casing further comprises: a base, being provided for thermal contacting a heat source while being arranged in thermal contact with the thermal dissipation device. 
     
     
         8 . The heat exchange chamber of  claim 1 , further comprising:
 a flow resisting portion, being disposed inside the cavity at a position proximate to the inlet, for enabling the cooling fluid to contact with the thermal dissipation device uniformly after flowing into the cavity through the inlet.   
     
     
         9 . The heat exchange chamber of  claim 8 , wherein the flow resisting portion is substantially a block hanging on the top panel of the casing to be used for enabling a neck to be formed inside the cavity at the position proximate to the inlet.
