Description

Even temperature plate

The new type is related to a heat dissipation technology, especially a temperature equalizing plate.

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 the problem of high heat generation, the industry has widely used the Vapor Chamber with good thermal conductivity characteristics (Vapor Chamber) However, there is room for improvement in the existing temperature-equalizing plates in terms of thermal conductivity, manufacturing cost and ease of manufacturing.

The conventional temperature equalizing plate mainly includes an upper shell and a lower shell, and a capillary structure is respectively installed in the inner space of the upper shell and the lower shell, and then the upper shell and the lower shell are welded correspondingly Then, the working fluid is filled into the upper shell and the lower shell, and finally the process of degassing and sealing is applied.

As the form of the heat source of electronic devices continues to evolve, the shape of the temperature equalization plate applied to the aforementioned heat source also changes, and the amount of working fluid will also affect its limited space for vapor and liquid changes, that is, too much The working fluid will cause the vaporized space to be greatly reduced, and too little working fluid will cause internal combustion and other undesirable conditions. Therefore, for the current large contact surface area or the uniform temperature plate of a specific shape, the filled work will often occur The fluid cannot be evenly and widely distributed in the internal space of each shell, which leads to the situation of inefficient heat conduction and heat dissipation.

In view of this, the creator of this new type of research focused on the lack of the above-mentioned existing technologies, and dedicatedly studied and cooperated with the application of academic principles to try to solve the above problems, which became the goal of improvement of this new type of creative.

In order to achieve the above objective, the present invention provides a temperature-equalizing plate, which includes a shell, a capillary structure, at least two liquid injection degassing pipes, and a working fluid. The shell includes a lower shell plate and a sealing seal corresponding to the lower shell plate A combined upper shell plate, a single chamber is formed between the upper shell plate and the lower shell plate; the capillary structure is disposed in the single chamber; each of the liquid injection and degassing pipes respectively penetrates the shell and communicates with the Single chamber; the working fluid is arranged in the single chamber.

The present invention also has the following effects. By evenly distributing the working fluid, the heat conduction and heat dissipation performance of the temperature equalizing plate can be improved, and the internal empty burning and other undesirable conditions can be effectively prevented. Through the average setting of the liquid injection and degassing tubes, the filling of the working fluid is simpler, which makes the manufacturing process easier.

Each liquid injection and degassing tube 30 is corresponding to the aforementioned groove 114 and recessed groove 121 and is connected to the side of the housing 10 and communicates with the aforementioned single chamber A. Each liquid injection and degassing tube 30 of this embodiment is located separately. They are arranged at equal intervals on the same side of the housing 10.

The working fluid 40 may be a pure water, which is filled into the single chamber A through the liquid injection and degassing tubes 30.

As shown in FIG. 3, the housing 10A of this embodiment is also generally rectangular. The difference from the above embodiment is that each of the liquid injection and degassing tubes 30 is located at the two opposite sides of the housing 10A and is misaligned. Configuration.

Referring to FIG. 4, the housing 10B of this embodiment is U-shaped, and the number of the liquid injection and degassing tubes 30 is three, and two of the liquid injection and degassing tubes 30 are respectively located in the middle of the opening side of the housing 10B. The other liquid injection degassing tube 30 is located in the middle of the closed side of the housing 10B.
