Description

Distributed water-cooling heat dissipation device

Technical Field

The utility model relates to an electron device's heat dissipation field especially relates to a distributing type water-cooling heat abstractor.

Background

With the development of electronic information technology, the computing power of desktop personal computers is becoming stronger, and the heat generation of CPUs, GPUs and other components of the system is increasing, so that the requirement for the heat dissipation capability of the computer system is also becoming higher.

In various heat dissipation schemes of core devices such as a CPU (central processing unit) or a GPU (graphics processing unit) and the like in a desktop personal computer at present, a water-cooling radiator with a better heat dissipation effect generally comprises a water pump unit, a heat exchange unit, a collecting pipe heat dissipation unit comprising a fan and a connecting water pipe. As shown in fig. 1, the heat dissipating loop of the prior art includes a heat dissipating unit 1, a heat exchanging unit 2, a driving unit 3, and a connecting pipeline 4, wherein the heat dissipating unit 1 further includes a U-shaped water path heat dissipating and discharging assembly 101, a water inlet chamber 1011, a water outlet chamber 1012, a water rotating chamber 1013, a water inlet 1014, a water outlet 1015, and the like.

The heat dissipation working mode in the prior art is as follows: the water pump in the driving unit 3 drives water to flow through the heat exchange unit 2 for heat exchange and then to flow out hot water, the high-temperature water flows to the water inlet chamber 1014 of the upper half of the radiating water drain through the connecting pipeline 4, the water flow entering the water inlet chamber 1014 flows to the rotary water chamber 1013 through a plurality of shunt water channels (high-frequency tubes) 1016 of the upper half of the radiating water drain, and is turned by 180 degrees after the water flow is converged and then flows to the water outlet chamber 1015 through a plurality of flow channels (high-frequency tubes) of the lower half of the radiating water drain, and then the water flow returns to the pump head for heat exchange again through the connecting pipeline 4. As shown in fig. 2.

Folding heat dissipation belts are welded between the outer portions of a plurality of high-frequency pipe runners of the heat dissipation unit, air provided by the fan flows downwards, and the water temperature of the water body is reduced step by step along the water flow direction.

The heat dissipation mode in the prior art has the following problems:

first, in the water-cooled heat sink in the prior art, only a single heat dissipation water drain is provided, and the heat dissipation capability is affected by the water drain specification, and generally, the larger the specification of the single water drain is, the stronger the heat dissipation capability is, but the heat dissipation capability is limited by the size of the chassis and the installation conditions, and at present, the largest water drain specification is 120 × 480mm, that is, 4 heat dissipation fans with 120 specifications can be installed. With the gradual increase of the heating power of the CPU, the heat dissipation capability of the water has become one of the major bottlenecks of the heat dissipation capability of the water-cooling heat dissipation system.

Secondly, the heat dissipation efficiency of the heat dissipation water in the prior art is low, and the specific analysis is as follows:

the existing heat dissipation water discharge design mode is a U-shaped water channel heat dissipation water discharge assembly with a U-shaped flow channel, and after hot water flows from a water inlet chamber to a rotary water chamber through an upper half part of a collecting pipe, the hot water needs to turn back 180 degrees in the rotary water chamber and then flows to a water outlet chamber through a lower half part of the collecting pipe. In the process, the water flow resistance is very high, and a large number of vortexes can be formed in the rotary water chamber, so that the power output of the water pump is greatly consumed, and the overall flow of the system is influenced.

In addition, in the U-shaped waterway heat dissipation fin assembly, the temperature of water is gradually lowered as it flows in the heat dissipation fin, and each heat dissipation fan needs to span 50% of the relatively hot water flow passage and 50% of the cold water flow passage in this arrangement. It is known that, in a forced convection airflow field provided by a fan, the larger the temperature difference between a radiated object and the ambient temperature is, the better the heat radiation effect is. If the temperature difference between the object to be cooled and the ambient air temperature is small, the operation of the fan will not work as intended. As can be seen from the above analysis, in the prior art, half of any heat dissipation fan disposed above the heat dissipation water has a relatively high temperature difference, and the other half has a relatively low temperature difference, which ultimately results in the failure of optimal fan working efficiency.

In view of the above, there is a need to provide a new heat dissipation concept to solve the above problems of the prior art.

The information disclosed in this background section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information constitutes prior art already known to a person skilled in the art.
