Abstract

A fluid heat exchanger with pump, adapted to drive a fluid for heat transfer, comprises a heat conduction unit, a diversion unit, and a housing unit. The heat conduction unit includes a heat conductor. The diversion unit includes a cover and a diversion plate. A cooling chamber is defined by the cover and the heat conductor. The cover is provided with a fluid stopper. The diversion plate is disposed in the cooling chamber, and one end of the diversion plate abuts against the fluid stopper, so that the cooling chamber is divided into an upper passage and a lower passage. The housing unit includes a housing and a pump module. The fluid in the housing is driven by the pump module to flow through the upper passage to the lower passage, and then the fluid returns to the housing to carry the heat from the heat conductor.

First claim

I claim:

1. A fluid heat exchanger with pump, adapted to drive a fluid for heat transfer, comprising:
a heat conduction unit ( 3 ), including a heat conductor ( 31 );
a diversion unit ( 4 ), including a cover ( 41 ) arranged on the heat conductor ( 31 ) and a diversion plate ( 42 ), wherein a cooling chamber ( 43 ) is defined by the cover ( 41 ) and the heat conductor ( 31 ), the cover ( 41 ) is provided with a fluid stopper ( 411 ), the diversion plate ( 42 ) is disposed in the cooling chamber ( 43 ), and one end of the diversion plate ( 42 ) abuts against the fluid stopper ( 411 ), so that the cooling chamber ( 43 ) is divided into an upper passage ( 431 ) and a lower passage ( 432 ); and
a housing unit ( 5 ), including a housing ( 51 ) covering the cover ( 41 ) and accommodating the fluid, and a pump module ( 52 ) disposed in the housing ( 51 ), wherein the pump module ( 52 ) has a motor ( 521 ) arranged in the housing ( 51 ), and an upright impeller ( 522 ) connected to the motor ( 521 ), the housing ( 51 ) has a driving chamber ( 511 ) for accommodating the upright impeller ( 522 ), and the upright impeller ( 522 ) is driven by the motor ( 521 ) to rotate in the driving chamber ( 511 ), the fluid in the housing ( 51 ) is driven by the pump module ( 52 ) to flow through the upper passage ( 431 ) to the lower passage ( 432 ), and then the fluid returns to the housing ( 51 ) to carry the heat from the heat conductor ( 31 );
wherein the diversion plate ( 42 ) defines an XZ plane, the rotation direction of the upright impeller ( 522 ) defines a XY plane, and the XZ plane and the XY plane are perpendicular to each other.

2. The fluid heat exchanger with pump as claimed in claim 1 , wherein the housing ( 51 ) is provided with a first channel ( 512 ) connected to the driving chamber ( 511 ), and a first connector port ( 513 ) connected to the first channel ( 512 ) for loading the fluid.

3. The fluid heat exchanger with pump as claimed in claim 1 , wherein the housing is provided with a second channel ( 514 ) connected to the lower passage ( 432 ), a second connector port ( 514 ) connected to the second channel ( 514 ) for discharging the fluid, and a third connector port ( 516 ) connected to the second channel ( 514 ).

4. The fluid heat exchanger with pump as claimed in claim 1 , wherein the heat conductor ( 31 ) is provided with a surrounding wall ( 311 ), and a bottom wall connected ( 312 ) to the surrounding wall ( 311 ).

5. The fluid heat exchanger with pump as claimed in claim 1 , wherein the heat conduction unit ( 3 ) further includes a fin array ( 32 ) located on the bottom wall ( 311 ) and disposed in the lower passage ( 432 ).

6. The fluid heat exchanger with pump as claimed in claim 5 , wherein the fin array ( 32 ) is composed of a plurality of heat sink fins, and front and back ends of the fin array ( 32 ) are provided with a respective inclined portion ( 321 ), so that the plurality of heat sink fins form a pattern with two lower ends and a higher middle.

7. The fluid heat exchanger with pump as claimed in claim 1 , wherein the cover ( 41 ) is provided with an inlet ( 412 ) and an outlet ( 413 ), the inlet ( 412 ) is connected to the upper passage ( 431 ), and the outlet ( 413 ) is connected to the lower passage ( 432 ).

8. The fluid heat exchanger with pump as claimed in claim 1 , further comprises a mounting unit ( 6 ), which includes a bracket ( 61 ) connected to the housing ( 51 ), and a mounting hole ( 62 ) provided on the bracket ( 61 ).
