The first chamber 102 is surrounded by the inner wall of the partition body 14 and the top wall 130 of the cover body 13 for receiving the impeller group 20; the second chamber 104 surrounds the support column 136 of the cover body 13 and is sandwiched between the cover body The space between the top wall 130 of the 13 _ and the mounting plate 41, but does not include the cavity 1360 surrounded by the support column 136 of the cover 13 . In addition, the second chamber 104 further includes a gas storage chamber 18 . The air plenum 18 is surrounded by the outer wall of the filter 17 and the inner wall of the cover 13 for storing the gas escaping from the small hole 1704 of the filter 17; the third chamber 106 is for accommodating the heat absorbing body 40, The cavity 1360 is formed by a space 45 located under the cavity 1360 and sandwiched between the mounting plate 41 and the base 16. The third cavity 106 communicates with the first cavity 102 through a through hole 135 above the cavity 1360. Thus, the first and third chambers 102, 106 that are in communication with each other together constitute a working channel for the liquid. The water inlet 122 is located at a corresponding position of the second chamber 104, and the liquid enters the second chamber 104 from the water inlet 122; the water outlet 124 is located at a corresponding position of the first chamber 102, and is received in the first chamber 102. The impeller 21 flows out of the water outlet 124 to drive the liquid flowing into the first chamber 102. The fourth chamber 108 is located above the second receiving portion 142 of the partition 14 and surrounds the first receiving portion 140. The fourth chamber 108 a closed chamber surrounding the first chamber 102 and isolated from the first, second and third chambers 102, 104, 106, respectively, and liquid cannot flow into the closed chamber, the fourth chamber 108 being used for The drive unit 30 is housed. 13 200815677 The drive unit 30 housed in the fourth chamber 108 includes a motor with a stator 32 and a circuit board 33 placed on top of the stator 32 and electrically connected to the stator 32. The stator 32 is disposed on the outer wall of the first receiving portion 140 of the partition body 14 and cooperates with the protruding rib 144 of the outer wall, which is axially supported by the top wall of the second receiving portion 142 of the partition body 14 in the radial direction. The cylinder 11 is abutted against the cylinder 11 in the body 12, and the stator 32 has a plurality of coils 320 wound around the stator 32. The circuit board 33 is placed on the top wall 143 of the separator 14 to provide a continuous current to the coil 320 of the given sub-32 to generate a magnetic field to urge the impeller 21 to rotate. The top cover 15 disposed on the top of the closed chamber is substantially square. The four corners of the top cover 15 are extended downwardly with pins 152 for engaging with the protrusions 120 of the body 12, so that the top cover 15 is mounted on the body 12. The top of the. An upward protrusion 150 protrudes upward from a middle portion of the top cover for accommodating and contacting the electronic component 330 on the circuit board 33 of the driving unit 30. The top cover 15 is made of a material having good thermal conductivity, and may be metal or non-metal. In the present embodiment, the material of the top cover 15 is aluminum for dissipating heat generated by the electronic component 330 on the circuit board 33. In order to ensure the close contact between the protruding portion 150 of the top cover 15 and the heat-generating electronic component 330, a compressible heat-conductive film 151 having a certain thickness is attached to the bottom surface of the protruding portion 150 and the electronic component 330 for contacting the top cover 15 The heat transfer between the electronic component 330 and the heat generated by the electronic component 330 deforms the thermal conductive film 151 to fill the gap between the electronic component 330 and the top cover 15 and the electronic component 330. The large heat dissipation area of the cover 15 achieves the purpose of heat dissipation. When the invention is in use, the liquid is driven by the impeller 21 from the water inlet 124 into the filter 17 placed in the second 14 200815677 • chamber 104, and the gas mixed into the liquid passes through the small hole of the filter 17 when passing through the filter 17. Escaped in 1704 and stored in the gas storage chamber 18; the liquid flowing in the filter 17 flows out through the opening 1320 in the casing 13, and from the inlet region 137 of the casing 13 due to the gravity of the liquid The bottom portion flows into the third chamber 106 along the end edge of the heat absorbing body 40. Since the base 16 is in close contact with the heat-generating electronic components on the circuit board, thereby absorbing heat generated by the electronic component, the base 16 absorbs heat and then transfers to the third chamber. The liquid of the chamber _106, the liquid flows through the passage 44 of the heat absorbing body 40, and exchanges heat with each of the bodies 42 of the heat absorbing body 40; then the liquid flows from the through hole 135 of the hood 13 into the first chamber 102. The impeller 21 is pulled out from the water outlet 124 by the centrifugal force of the impeller 21; at the same time, the rotation of the impeller 21 is driven by the drive unit 30 located in the fourth closed chamber 108, and the electronic component 330 on the circuit board 33 thereof is generated when the drive unit 30 operates. Mass Heat, due to the arrangement of the top cover 15, the heat generated by the electronic component 330 can be quickly transferred to the top cover 15, and the heat on the circuit board 33 can be quickly dissipated through the top cover 15 to the surrounding environment, thereby making the first The temperature of the four closed chambers 108 is maintained within the normal range without causing the temperature of the circuit board 33 of the drive unit 30 to be too high. As a result, the present invention can effectively avoid the phenomenon that the temperature of the circuit board 33 is lowered due to the circuit board 33 of the driving unit 30 being in the sealed chamber, thereby reducing the life of the circuit board 33. In summary, the present invention complies with the requirements of the invention patent and submits a patent application according to law. The above is only the preferred embodiment of the present invention, and equivalent modifications or variations made by those skilled in the art will be included in the following claims. 15 200815677 [Simple description of the figure] ^ _ Figure 1 is a perspective exploded view of the pump of the present invention.
