Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] Such as figure 1 , 2, 3, 4 show:

[0021] A belt-type phase change heat dissipation device, which is composed of a phase change cavity 1-1 and a heat dissipation belt 1. The phase change cavity 1-1 is a sealed cavity made according to the principle of a heat pipe. The surface of the phase change cavity is convenient for installation and heat dissipation. The slot 1-2 of the band, the heat dissipation band 1 is installed in the slot. Frame 2 is mounted on the outside of groove 1-2. Such as image 3 , as shown in 4, there are multiple phase-change chambers 1-1, which are placed in layers, and the heat is transferred to the next phase-change chamber 1-1 through the teeth 1-3 of the phase-change chamber.

[0022] Such as Figure 5 , as shown in 6:

[0023] A belt-type phase-change heat dissipation device, consisting of a heat pipe 2-1 and a hea...

Abstract

The invention relates to electronic equipment, in particular to dissipation of heat generated by high-power electronic equipment such as a server, network equipment and an LED lamp, and discloses belttype phase change heat dissipation equipment The belt type phase change heat dissipation equipment is composed of a phase change cavity and a heat dissipation belt, the surface of the phase change cavity is provided with a groove facilitating installation of the heat dissipation belt, and the heat dissipation belt is installed in the groove. Belt type phase change heat dissipation equipment is composed of a heat pipe and the heat dissipation belt, and the heat dissipation belt is installed at the condensation end of the heat pipe, or the heat dissipation belt is fixed on a frame, the frame isinstalled at the condensation end of the heat pipe, and heat is transmitted to the heat dissipation belt through the frame. The belt type phase change heat dissipation equipment can be also composedof a uniform temperature plate and a heat dissipation belt, and one side of the heat dissipation belt is installed on the uniform temperature plate, a frame can be installed on the other side of the heat dissipation belt to protect the heat dissipation belt, and the frame can make contact with the heat dissipation belt to conduct heat. According to the above three technical schemes of the invention, the heat dissipation belt is mounted in the groove of the phase change cavity and on the heat pipe and the uniform temperature plate, heat can be rapidly diffused to the heat dissipation belt, a large heat dissipation area is obtained, and rapid heat dissipation can be achieved through a turbulent flow structure of the heat dissipation belt. Therefore, the heat dissipation efficiency can be effectively improved.

Description

technical field [0001] The invention relates to electronic equipment, in particular to the dissipation of heat generated by high-power electronic equipment such as servers, network equipment, and LED lamps. Background technique [0002] The heat pipe is a highly efficient heat sink, which uses the phase change process of the liquid medium to evaporate at the hot end and then condenses at the cold end to conduct heat quickly. The inside of the heat pipe is pumped into a negative pressure state and filled with a suitable liquid, which has a low boiling point and is easy to volatilize. There is a liquid-absorbing core inside the heat pipe, which is made of capillary porous material. One end of the heat pipe is the evaporation end, and the other end is the condensation end. When one end of the heat pipe is heated, the liquid in the capillary quickly vaporizes, and the vapor flows to the other end under the power of thermal diffusion, and condenses at the cold end to release hea...
