Cooling plate module

Abstract

A cooling plate module includes a cooling plate and a liquid driving module. The liquid driving module includes an accommodation chamber and a liquid driving unit used to driving cooling liquid. The liquid driving module includes a liquid inlet communicated to the accommodation chamber and a first liquid outlet is communicated to the bottom of the accommodation chamber. A cap encloses the first liquid outlet and a second liquid outlet is defined on the cap. The cooling plate is assembled with the cap to define a closed space therein and the first liquid outlet is corresponding to the heat-dissipating plates. Therefore, there is no duct connecting between the cooling plate and the liquid driving module, the stagnant problem caused by pressure difference can be prevented and the cool liquid can directly flush the heat-dissipating plates for enhancing heat dissipation efficiency.

1 . A cooling plate module used in a liquid cooling cyclic mechanism for removing heat from a heat source, comprising 
 a cooling plate comprising a heat absorbing face on bottom thereof and being in contact with a heat source, and a plurality of heat-dissipating plates on top face of the cooling plate;    a liquid driving module comprising an accommodation chamber and a liquid driving unit used to driving a cooling liquid, the liquid driving module comprising a liquid inlet communicated to the accommodation chamber and a first liquid outlet communicated to a bottom of the accommodation chamber; a cap enclosing the first liquid outlet and a second liquid outlet being defined on the cap;    wherein the cooling plate is assembled with the cap to define a closed space therein and the first liquid outlet is corresponding to the heat-dissipating plates.    
   
   
       2 . The cooling plate module as in  claim 1 , wherein the heat-dissipating plates are arranged in one of longitudinal manner and transverse manner.  
   
   
       3 . The cooling plate module as in  claim 1 , wherein the heat-dissipating plates are such arranged that a runner is defined between the plurality of heat-dissipating plates and forms a closed loop.  
   
   
       4 . The cooling plate module as in  claim 1 , wherein the liquid driving module is a reciprocating pump.  
   
   
       5 . The cooling plate module as in  claim 1 , wherein the liquid driving module is a centrifugal pump.  
   
   
       6 . The cooling plate module as in  claim 1 , wherein the liquid driving module is an axial-flow pump.  
   
   
       7 . The cooling plate module as in  claim 1 , wherein a sealing pad is provided between the cap and the cooling plate.
