Description

Heat exchanger structure

technical field

The utility model relates to a heat exchanger, in particular to a heat exchanger structure for improving heat transfer efficiency.

Background technique

With the advancement of electronic information technology, the use of electronic equipment (such as computers, notebook computers, communication chassis...etc.) Waste heat will be generated. If the above-mentioned waste heat cannot be discharged from the electronic equipment in time, it is very easy to accumulate the waste heat in the electronic equipment, causing the temperature inside the electronic equipment and the electronic components inside the electronic equipment to continue to rise, which will cause the electronic components to fail due to overheating , damage or reduced operating efficiency.

In order to improve the above-mentioned heat dissipation problem in the prior art, it is generally more common to install a heat dissipation fan in the electronic equipment to force heat dissipation. Therefore, the industry seeks another solution, which is to use a water-cooled heat sink directly attached to the heat-generating components, such as (Central Processing Unit (CPU), MPU, South and North Bridge chips or other Electronic components that generate high heat, etc.), and a pump introduces the cooling liquid from the water storage tank into the water-cooled heat sink, so that the cooling liquid exchanges heat with the heat absorbed by the water-cooled heat sink from the heating component, and the cooling liquid Then it flows out from a water outlet of the water-cooled heat sink to a heat dissipation module, and then returns to the aforementioned water storage tank after being cooled. Therefore, the circulation of the cooling liquid helps to dissipate heat, lower the temperature of the heating element, and enable the heating element to operate smoothly.

However, although the water-cooled heat sink can improve the problem of using airflow to dissipate heat, another problem arises, that is, the end surface (that is, the heat-absorbing surface) of the water-cooled heat sink that is close to the heating component is only concentrated in the same place relationship, so that the cooling liquid in the water-cooled device only has a heat exchange effect between the lowermost fluid part and the heat-absorbing surface, while the fluid in the middle and upper layers does not produce heat exchange with the heat-absorbing surface, and the cooling liquid The time spent in the water-cooled heat sink is also too short, so that the cooling liquid has not fully absorbed enough heat (that is, heat exchange), and it is immediately and quickly led out from the aforementioned water outlet, so that the water-cooling function is greatly reduced and its heat transfer is reduced. The effect is not good, and the heat dissipation effect is not obvious.

Because the internal flow channels of the existing water-cooled heat exchanger structure are one-way smooth flow channels, the stagnation time of the cooling liquid in these flow channels is shorter, and the heat source taken away is less. Therefore, the overall heat exchange is improved. The efficiency and heat transfer effect are obviously not good, and the heat dissipation effect is not ideal; therefore, the prior art has the following disadvantages:

1. Poor heat exchange efficiency;

2. The cooling effect is not good.

In view of the shortcomings derived from the above-mentioned conventional products, the creators of this case exhausted their minds and used their years of experience in this industry to study and innovate with great concentration, and finally successfully developed and completed this "heat exchanger structure" case. A creation with enhanced efficacy.
