Description
Technical Field
The present invention relates to a water-cooling pump structure with a check valve and a water-cooling module thereof, and more particularly, to a water-cooling pump structure with a check valve and a water-cooling module thereof, which can prevent a cooling liquid from flowing back.
Background
In the current computer or electronics industry, a large variety of process wafers are used, such as: as the integration density and the operation frequency of a cpu and a graphic chip, or other chips such as a north-south bridge processing chip, etc. are higher and higher, the heat generated during operation is also higher, which is also called a heating element. Since the heating elements may be abnormally operated when the operating temperature is too high, and even may be burned out, various heat dissipation devices are also available in the market to effectively reduce the heat, which are tightly attached to the heat-overflowing surfaces of the heating elements, so as to assist the heat dissipation by conduction, convection or radiation, thereby keeping the heating elements operating at the normal operating temperature.
The most common heat dissipating device is made of metal (such as aluminum or copper) with easy heat conduction through various processing, and comprises a base, a plurality of heat dissipating fins and a heat dissipating fan, wherein the base is in close contact with the heating element, heat energy is directly conducted to the heat dissipating fins, and the surface of the heat dissipating fins generates heat convection with the outside air, so that the heat energy is dissipated to the outside, or a heat pipe is combined to enhance the heat dissipating effect, the heat pipe is filled with a liquid heat dissipating medium in a closed pipe body, the main component of the heat dissipating medium is water, and the rest are special components capable of increasing the heat transfer capability of the liquid. One end of the heat pipe is an evaporation end and is in contact with the heating element so as to absorb heat of the heat pipe and evaporate the heat-dissipating medium into a gas state after absorbing heat, and the gas state moves to a condensation end at the other end of the heat pipe to dissipate the heat, so that a closed heat-dissipating circulation stroke is formed, and a large amount of heat can be taken away by the heat-dissipating medium at one time, thereby achieving the purpose of improving the heat-dissipating efficiency.
In addition, there is also a water-cooling heat dissipation module which simply uses liquid circulation to dissipate heat, and uses a circulation pump to drive a cooling liquid (usually water) which has large specific heat and can absorb heat when flowing through the heating element, and uses the flow of the cooling liquid to take the heat away from the heating element, and discharges the heat in the passing pipeline or water storage tank, so as to achieve the purpose of dissipating the heat; however, in order to increase the heat dissipation efficiency, some people use the water-cooling heat dissipation module to dissipate heat by means of stacking up and down pumps, and the cooling liquid in each pump is collected and then flowed out through a pipe, so as to continuously perform the cooling liquid circulation heat dissipation method.

Through the structural design of the water cooling module, when one side of the heat dissipating unit 4 of the water cooling module contacts a heat generating element (not shown) to start operating, the cooling liquid 5 in the heat dissipating unit 4 firstly flows into the water storage tank 6 through the outlet 42, then flows into the second tube 32, and then flows into the third water inlet 2521, then the cooling liquid 5 is divided by the third water inlet 2521 of the second connector set 25, a part of the liquid flows into the second communicating tube 27 through the second water outlet 2511, and then enters the first pump chamber 2011 of the first pump unit 20 through the first water inlet 202, and then the cooling liquid 5 in the first pump chamber 2011 flows into the first space 212 of the first pump valve 21 through the first water outlet 203, and the first sealing element 2144 arranged in the first space 212 moves toward the second space 213 due to the pressure of the cooling liquid 5, so that the cooling liquid 5 can smoothly flow into the second space 213 and then enter the first connecting pipe 26 to flow into the first water inlet portion 2411 of the first joint set 24;
the other part of the liquid of the cooling liquid 5 which is branched flows from the third water outlet 2512 to the fourth communicating pipe 29, then flows from the second water inlet 222 to the second pump chamber 2211 of the second pump unit 22, then the cooling liquid 5 in the second pump chamber 2211 flows through the second water outlet 223 to the third space 232 of the second check valve 23, and the second sealing member 2344 arranged in the third space 232 pushes and opens the second sealing member 2344 towards the fourth space 233 due to the pressure of the cooling liquid 5, so that the cooling liquid 5 can smoothly flow into the fourth space 233, then flows into the third communicating pipe 28, then flows into the second water inlet 2412 of the first joint group 24, and is collected with the cooling liquid 5 flowing from the first water inlet 2411 at the first joint group 24, and then is discharged to the first water outlet 2421, then, the cooling liquid 5 flows back to a circulation chamber 43 (the circulation chamber 43 may be composed of a plurality of flow channels) of the heat dissipation unit 4 after passing through the first tube 31 and the water storage tank 6 in sequence, and thus circulates back and forth to complete the liquid cooling circulation of the water cooling module.
Through the design that the first check valve 21 and the second check valve 23 are respectively installed at the first water outlet 203 and the second water outlet 223 of the first pump unit 20 and the second pump unit 22, when any one of the pump units (i.e. any one of the first pump unit 20 or the second pump unit 22, the reference numerals of the elements in fig. 3C and 3D compared with this embodiment refer to the first pump unit 20 as a representative description) is destroyed and cannot operate, so that the cooling liquid 5 cannot be driven to flow, a backflow problem of the cooling liquid 5 is caused at this time, and when the cooling liquid 5 flows back, the circulation flow direction inside the water cooling module becomes unsmooth, and through the structure of the first sealing element 2144 (or the second sealing element 2344) inside the first check valve 21 (or the second check valve 23) of the present invention, the cooling liquid 5 can be prevented from flowing back to the first pump chamber 2011 (or the second pump chamber 2211), further, the problem of backflow of the cooling liquid 5 can be completely prevented (as is apparent from fig. 3D), and the heat dissipation efficiency can be greatly improved.
In addition, in order to achieve better heat dissipation effect, at least one heat dissipation element (such as heat dissipation fins, water drainage, etc.) can be added in the heat dissipation module to perform heat exchange heat dissipation on the cooling liquid 5.
As described above, the present invention has the following advantages over the prior art:
1. preventing backflow of the cooling liquid;
2. the heat dissipation efficiency is greatly improved.
The foregoing description is intended to be illustrative rather than limiting, and it will be appreciated by those skilled in the art that many modifications, variations or equivalents may be made without departing from the spirit and scope of the inventive concept, which is set forth in the following claims.
