Dual-chamber pump

Abstract

A pump has a housing, a driving assembly, a recycling assembly, a guiding assembly, and a heat-dissipating assembly. The housing has a driving chamber adapted for containing non-conductive liquid inside and having a top opening, a recycling chamber for containing coolant being adjacent to the driving chamber and having a bottom opening, and a top cap attached to a top of the housing to close the top opening of the driving chamber. The driving assembly is held in the driving chamber. The cycling assembly is held in the recycling chamber. The guiding assembly is held in the recycling chamber. The heat-dissipating assembly is attached to a bottom of the housing to close the bottom opening of the recycling chamber.

1 . A pump comprising:
 a housing comprising a driving chamber having a top opening, a recycling chamber for containing coolant being adjacent to the driving chamber and having a bottom opening, and a top cap attached to a top of the housing to close the top opening of the driving chamber, wherein the non-conductive liquid is filled with the driving chamber;   a driving assembly held in the driving chamber;   a cycling assembly held in the recycling chamber;   a guiding assembly held in the recycling chamber; and   a heat-dissipating assembly attached to a bottom of the housing to close the bottom opening of the recycling chamber.   
     
     
         2 . The pump as claimed in  claim 1 , wherein the recycling assembly is driven by the driving assembly to rotate and is adapted for leading the coolant to flowing into the recycling chamber via the guiding assembly. 
     
     
         3 . The pump as claimed in  claim 2 , wherein the driving assembly comprises
 a control circuit board; and   a stator having multiple iron core coils arranged in a circle on a bottom of the control circuit board; and   the control circuit board is adapted to be connected electrically to an outside electrical power source to make the iron core coils generate alternating magnetic field for driving the recycling assembly to rotate.   
     
     
         4 . The pump as claimed in  claim 3 , wherein the recycling assembly comprises
 a central axle; and   a rotating member having a center connected to the central axle and comprising a rotator and a blade wheel formed as a single part with the rotator; and   multiple through holes are defined through the blade wheel.   
     
     
         5 . The pump as claimed in  claim 4 , wherein the rotator is a hollow collar having multiple magnetic poles arranged in annularly corresponding radially to the stator and driven to rotate by the alternating magnetic field generated by the stator. 
     
     
         6 . The pump as claimed in  claim 5 , wherein the blade wheel comprises multiple blades formed on and protruding from and being arranged radially on a bottom of the blade wheel; and
 each blade is curved.   
     
     
         7 . The pump as claimed in  claim 6 , wherein the through holes in the blade wheel are located at gaps between the blades. 
     
     
         8 . The pump as claimed in  claim 7 , wherein the guiding assembly comprises
 a guiding cover;   a guiding board attached to a bottom of the guiding cover; and   a guiding channel defined in the guiding cover and the guiding board to lead the coolant to the heat-dissipating assembly.   
     
     
         9 . The pump as claimed in  claim 8 , wherein the heat-dissipating assembly comprises a bottom board attached to the bottom of the housing and a heat-dissipating block mounted on the bottom board. 
     
     
         10 . The pump as claimed in  claim 9 , wherein the housing has an inlet communicating with the recycling chamber and an outlet communicating with the recycling chamber. 
     
     
         11 . The pump as claimed in  claim 1 , wherein the driving assembly comprises
 a control circuit board; and   a stator having multiple iron core coils arranged in a circle on a bottom of the control circuit board; and   the control circuit board is adapted to be connected electrically to an outside electrical source to make the iron core coils generate alternating magnetic field for driving the recycling assembly to rotate.   
     
     
         12 . The pump as claimed in  claim 11 , wherein the recycling assembly comprises
 a central axle; and   a rotating member having a center connected to the central axle and comprising a rotator and a blade wheel formed as a single part with the rotator; and   multiple through holes are defined through the blade wheel.   
     
     
         13 . The pump as claimed in  claim 12 , wherein the rotator is a hollow collar having multiple magnetic poles arranged in annularly corresponding radially to the stator and driven to rotate by the alternating magnetic field generated by the stator. 
     
     
         14 . The pump as claimed in  claim 13 , wherein the blade wheel comprises multiple blades formed on and protruding from and being arranged radially on a bottom of the blade wheel; and
 each blade is curved.   
     
     
         15 . The pump as claimed in  claim 14 , wherein the through holes in the blade wheel are located at gaps between the blades. 
     
     
         16 . The pump as claimed in  claim 15 , wherein the guiding assembly comprises
 a guiding cover;   a guiding board attached to a bottom of the guiding cover; and   a guiding channel defined in the guiding cover and the guiding board to lead the coolant to the heat-dissipating assembly.   
     
     
         17 . The pump as claimed in  claim 16 , wherein the heat-dissipating assembly comprises a bottom board attached to the bottom of the housing and a heat-dissipating block mounted on the bottom board. 
     
     
         18 . The pump as claimed in  claim 17 , wherein the housing has an inlet communicating with the recycling chamber and an outlet communicating with the recycling chamber.
