Temperature plate and heat pipe combination structure

This creation is about a heat transfer technology, especially a combination of a uniform temperature plate and a heat pipe.

As the computing speed of electronic components continues to increase, the heat generated by them is getting higher and higher. In order to effectively solve this problem of high heat generation, the heat pipe and the temperature equalizing plate (Vapor) with good thermal conductivity are already available in the industry. Chamber) is widely used, in which the heat pipe has the same flow direction of the internal working fluid, but the heat that can be transmitted is limited due to the limitation of the volume, and the temperature plate has a spacious heating area. The heat source is directly attached to the conduction, but the flow of the gaseous working fluid is quite disordered, which will limit the heat dissipation performance.

In order to solve the above problems, the heat pipe and the temperature equalizing plate have been combined to form a combined structure, wherein the heat pipe is connected to one side of the temperature equalizing plate, and the inner space and the temperature equalizing plate of the heat pipe are allowed. The internal spaces are interconnected.

However, the conventional uniform temperature plate and heat pipe combination structure, although having the heat dissipation performance, has the following problems, because the capillary structure inside the heat pipe fails to adhere to the capillary structure inside the temperature equalizing plate, thereby causing the liquid state. The interruption or discontinuity of the working fluid during the reflow process will greatly reduce its heat dissipation performance. In addition, the wall thickness of the uniform temperature plate is generally quite thin. In order to allow the heat pipe to be stably held on the temperature equalizing plate, it is necessary to form a convex ring on the wall plate of the temperature equalizing plate to provide the heat pipe as a support, so that The cumbersome process and the increase in production costs are urgently needed to be improved.

One of the aims of the present invention is to provide a combination of a uniform temperature plate and a heat pipe, which not only facilitates the connection and fixing of the heat pipe, but also can increase the reflow speed of the liquid working fluid.

In order to achieve the above purpose, the present invention provides a combination of a uniform temperature plate and a heat pipe, comprising a temperature equalizing plate, a first capillary structure, a heat pipe and a working fluid, the temperature equalizing plate including an upper metal shell and corresponding a lower metal shell of the upper metal shell is tightly sealed, and a cavity is formed between the upper metal shell and the lower metal shell, the lower metal shell has a vertical plate, and a vertical hole connecting the cavity is opened in the vertical plate The first capillary structure is disposed in the cavity, the first capillary structure is provided with a receiving hole corresponding to the through hole; the heat pipe comprises a tube body and a second capillary structure, and the second capillary structure is disposed on the tube Forming a bare section in the body and extending outside the tube, the heat pipe piercing the through hole and the receiving hole, so that the exposed section and the receiving hole of the first capillary structure are attached; the working fluid is filled in the volume Inside the cavity.

The present invention also has the following effects: the first capillary structure and the second capillary tissue are attached to contact to increase the reflow speed of the working fluid. By the arrangement of the conical receiving holes, it is possible to achieve the effect of sharing the first capillary structure in response to variations in the outer diameters of the various heat pipes and variations in the outer diameter of the heat pipes during the machining process. The through holes of the heat pipe are accommodated in the receiving holes, so that the returning liquid working fluid can pass through the through holes, thereby increasing the reflux speed of the liquid working fluid. By the arrangement that the receiving hole is a blind hole, it is possible to restrict the heat pipe that penetrates the receiving hole, thereby improving the ease of combined installation.
