Problems solved by technology

[0013] However, in this case, the connecting portion between the pump 1 and the radiator 5 (in the figure, the inlet portion 16 and the outlet portion 17 of the pipe 14) is bent at two acute angles, and since the pipe is long As a result, the pressure loss of the flow path increases, and the flow rate and velocity of the fluid decrease, so good cooling performance cannot be obtained.

no. 2 Embodiment

[0063] exist Figure 6 In the shown second embodiment, the suction port 26 and the discharge port 27 of the pump 21 are directed in different directions so that only the suction port 26 is directed obliquely downward. In this case, the cooling device 71 is provided with a heat absorbing portion 72 separate from the pump 21, and the heat absorbing portion 72 is connected to the pump 21 (discharge port 27) and the heat dissipation portion 52 (inlet port) by connecting pipes 73 and 74. Section 63). At this time, the heat-absorbing part 72 flows the fluid discharged from the pump 21 and is in close contact with the heat-generating component. At this time, an obtuse angle portion exists at the connecting pipe 65 which is a connecting portion of the pump 21 (suction port 26 ) and the heat dissipation portion 52 (outlet portion 64 ).

[0064] Even in this case, in the pump 21, the heat absorbing portion 72 and the heat radiating portion 52, which are members to be connected, can be...

no. 3 Embodiment

[0066] exist Figure 7 In the third embodiment shown, the pump 21 of the cooling device 81 has a plurality of suction ports 26 and discharge ports 27 on both sides, and the heat dissipation part 52 is connected to each suction port 26 and discharge port 27 . In this case, the suction port 26 and the discharge port 27 are directed differently as in the above-mentioned second embodiment, but they may be reversed in the same manner as above, or may be directed differently in the same manner as in the first embodiment. Furthermore, the pump 21 is integrated with the heat absorbing portion. In addition, in this case, the connecting portion of the pump 21 (suction port 26 ) and the outlet portion 64 of the radiator 52 has an obtuse angle, and when the directions of the suction port 26 and the discharge port 27 of the pump 21 are reversed, the pump 21 The connecting portion between (the discharge port 27 ) and the inlet portion 63 of the heat dissipation portion 52 also has an obtus...

no. 4 Embodiment

[0069] exist Figure 8 In the fourth embodiment shown, the pump 21 has a plurality of suction ports 26 and discharge ports 27 on both sides, as in the third embodiment. For the cooling device 91, a heat dissipation part 52 is connected to each suction port 26 and the discharge port 27 of the cooling device 91, and a heat absorbing part separated from the pump 21 is respectively connected between each discharge port 27 of the pump 21 and each heat dissipation part 52. Section 72. In this case, the suction port 26 and the discharge port 27 of the pump 21 are directed differently as in the above-mentioned second embodiment, but they may be reversed in the same manner as above, or may be directed in the same manner as in the first embodiment. different. In this case, the connecting portion between the pump 21 (suction port 26) and the heat dissipation portion 52 (exit portion 64) has an obtuse angle, and when the directions of the suction port 26 and the discharge port 27 of the...

Abstract

This invention provides a pump which can be connected with a connection other party member without acutely bending a connection part, or lengthening wiring, and to provide a cooling device for sufficiently acquiring cooling performance. In a pump 21, directions of an inhalation port 26 and a discharge port 27 are oriented in different directions so that the pump can be connected with the connection other party member without acutely bending the connection part, or lengthening wiring. In the cooling device, a fluid for cooling can be circulated through a heat receiving part and a heat radiating part without lowering a flow rate or flow speed by reducing a pressure loss, and cooling performance can be sufficiently obtained.

Description

technical field [0001] The present invention relates to a pump with improved suction port and discharge port structure, a cooling device using the pump, electric equipment and a personal computer. Background technique [0002] In conventionally known pumps, a disc-shaped impeller is rotatably arranged in a pump chamber formed inside a casing having a suction port and a discharge port, and by rotating the impeller, the fluid is sucked from the pump groove by the pump chamber. The pump is sucked into the above-mentioned pump chamber and discharged from the above-mentioned discharge port. The above-mentioned impeller has pump grooves for transporting fluid (for example, liquid) in the outer peripheral portion. [0003] If the above-mentioned conventional pump is used in a cooling device for cooling heat-generating components such as electrical equipment, it can be considered Figure 11 and Figure 12 structure shown. In this case, on the casing 2 of the pump 1, the suction p...
