Description

The present invention relates to a heat dissipation structure, and in particular, at least one tube body is integrally installed inside the base by an insert mold method, and the tube body forms a fluid passage inside the base, thereby reducing cost and cooling fluid. The present invention relates to a heat dissipation structure that achieves leakage prevention.

As the operating performance of electronic equipment increases, electronic parts installed inside generate a large amount of heat during operation.
Usually, a heat radiator or a heat radiating fin is installed on an electronic part to expand a heat radiating area, thereby enhancing a heat radiation effect.
However, since the heat radiator and the heat radiation fin perform heat radiation by radiation, there is a limit to the heat radiation effect achieved.
For this reason, in the current technology, a method of enhancing the heat radiation performance using a water-cooled heat radiation module has been widely adopted.

The water-cooled heat radiation module is composed of a water-cooling head, a pump, a water box, and at least one tube, and the parts are connected in series to constitute a heat radiation circuit.
The water cooling head is made of a copper material, and a plurality of fluid passages are opened therein, and the pipe body, the pump, and the water box are connected in series.
When heat is transmitted in contact with the water cooling head and at least one heat source, the heat dissipating fluid in the water box is pressurized through the pump and sent into a fluid passage inside the water cooling head.
Further, the heat-dissipating fluid transfers heat absorbed by the water-cooling head to the water box and performs heat exchange.
The fluid passage inside the water-cooled head is formed by opening a groove on one side of the water-cooled head by machining (milling or the like) and then sealing the groove with another material.

As a material for the water cooling head, a material (such as a copper material) having excellent heat conduction efficiency is selected, and the copper material is processed.
However, since the water-cooling head is in contact with the heat source only on one side and can conduct heat, the other part becomes an ineffective area, and it can be said that the material is wasted.
Further, when the water-cooled head is used for a certain period, the material itself is oxidized or deteriorated to cause breakage.
As a result, a situation occurs in which the radiating fluid leaks outside in the fluid passage, and there is a risk of serious damage to the electronic equipment used in association therewith.
In other words, the conventional techniques have the following drawbacks.
1. Cooling fluid leaks easily.
2.
Production cost is high.
The present invention has been made in view of the above-described drawbacks of the conventional heat dissipation structure.
