Description

A vapor chamber heat pipe radiator

【Technical field】

The utility model relates to a radiator, in particular to a heat pipe radiator. the

【Background technique】

Existing radiators mostly use heat dissipation fins for heat dissipation. In order to improve the heat dissipation effect, external devices such as fans are also used for active heat dissipation, but the energy consumption is large and the cost is high. The high heat dissipation power of the heat pipe makes the heat dissipation effect better, and the heat pipe is lighter than the heat dissipation fin heat pipe, which is convenient for transportation. However, the heat pipe of the existing heat pipe radiator is troublesome to fix, and it is usually fixed by welding. If the heat dissipation power is relatively large A lot of heat pipes will be installed, which will be very difficult for the welding process. It can be said that it is unrealistic in mass production, and the manufacturing cost will be greatly increased. Moreover, the heat transfer between the heat pipe and the heat source is carried out through the base. Since the base is mostly made of aluminum base, the heat distribution of the base is uneven, so the heat transfer effect is not good, thereby affecting the heat dissipation effect. the

The heat pipe includes a heat transfer section and a heat dissipation section. The heat transfer section is placed between the clamping plate and the base, and the heat dissipation section is placed in the air to dissipate heat. The radiator includes a fixing piece, and the fixing piece fixes the tail end of the heat dissipation section of each heat pipe. the

The base is provided with radial heat pipe grooves, the heat transfer section is placed in the heat pipe grooves, and the base is provided with an installation groove for installing a temperature chamber. the

The heat pipe is provided with several layers. the

The heat pipe is bent in an L shape or a U shape, and the heat pipe groove extends to the middle of the base. the

With the above technical solution, since the radiator only uses heat pipes for heat dissipation, the heat dissipation effect is good, and the heat from the heat source is absorbed and evenly diffused to the heat pipes by using a vapor chamber, so that the heat transfer effect is better and the heat diffusion is faster and more efficient. , the heat pipe is fixed and clamped on the base by using a clamping plate. This technology solves the cumbersome welding process of multiple heat pipes and is conducive to industrial mass production. A fixing piece at the end of the heat pipe can make the heat pipe fixed and positioned. , so that the heat pipe is not easily deformed. the

In order to facilitate the fixing and installation of the heat pipe 2, as shown in Figure 4, a heat pipe groove 1-1 is provided on the base 1, and in order to quickly transfer the heat in the middle of the base 1, the heat pipe groove 1-1 is extended to the base 1 In this way, the heat transfer section 2-1 of the heat pipe 2 can extend into the middle of the base 1, so that the contact area between the heat pipe 2 and the vapor chamber 5 is larger, and the heat can be transferred quickly and evenly. In this embodiment, the base 1 The heat pipe groove 1‐1 on the upper part penetrates the base 1, so that after the heat pipe 2 is installed, the vapor chamber 5 can be set on the base 1 on the side opposite to the heat pipe 2, and the vapor chamber 5 can be directly connected to the heat pipe. contact, and in order to facilitate the installation of the temperature chamber 5, there is an installation groove 1-2 on the base, and the chamber 5 is clamped in the installation groove 1-2, or it can be fixed on the on the base 1; or directly set the vapor chamber 5 on the base 1 on the side of the heat pipe groove 1-1 without using the penetrated heat pipe groove 1-1, so that the vapor chamber 5 can also function as a clamping plate 3, and can be in direct contact with the heat pipe 2 at the same time. If the uniform temperature plate 5 of this embodiment is not used to clamp the heat pipe, the clamping plate 3 is fixed on the base 1, and the clamping plate 3 and the base 1 are fixed by screw connection, which is convenient for disassembly and assembly. 3 and the base 1 are provided with a heat pipe 2, the heat pipe 2 includes a heat transfer section 2-1 and a heat dissipation section 2-2, and the heat transfer section 2-1 is fixed between the clamping plate 3 and the base 1 During the period, the cooling section 2-2 is placed in the air. At the end of the cooling section 2-2 of the heat pipe 2, there is a fixing piece 4. The fixing piece 4 fixes and positions the tail end of the heat pipe 2, so that the heat pipe is not easily deformed during transportation and installation, and the heat at the tail of the heat pipe can be balanced. transmission. the

As shown in Figure 2 and Figure 3, the heat transfer section 2-1 and the heat dissipation section 2-2 of the heat pipe 2 of the radiator are bent, which reduces the area of the radiator and conforms to the general heat dissipation structure for easy installation.
