Spring-shaped radiator and radiator with spring-shaped radiator

Abstract

Disclosed are a spring-shaped heat sink (10) and a radiator (1) with the spring-shaped heat sink (10). The spring-shaped heat sink (10) is formed integrally by winding a spring. The upper end of a first extension section (131) is connected to the upper end of an upper-layer spring body (110) and extends to the bottom surface of a lower-layer spring body (120). One end of a first heat conducting section (141) is connected to the lower end of the first extension section (131), and coiled on the inner side of the bottom surface of the lower-layer spring body (120) or encircled on the outer side of the bottom surface. The upper end of a second extension section (132) is connected to the lower end of the upper-layer spring body (110) and extends to the bottom surface of the lower-layer spring body (120). One end of a second heat conducting section (142) is connected to the lower end of the second extension section (132), and coiled on the inner side of the bottom surface of the lower-layer spring body (120) or encircled on the outer side of the bottom surface. The upper end of a third extension section (133) is connected to the upper end of the lower-layer spring body (120) and extends to the bottom surface of the lower-layer spring body (120). One end of a third heat conducting section (143) is connected to the lower end of the third extension section (133), and coiled on the inner side of the bottom surface of the lower-layer spring body (120) or encircled on the outer side of the bottom surface. The spring-shaped heat sink (10) has higher heat conduction efficiency and heat dissipation efficiency, good ventilation performance and greatly reduced weight, and the shape and size thereof can be set based on requirements.

Problems solved by technology

[0002] Many devices will generate heat during operation. It is necessary to use heat dissipation components (mainly heat dissipation blades) to discharge the heat out of the equipment to ensure the stability of the equipment and prolong the service life of the equipment. To achieve the heat dissipation function of the radiator, two problems need to be solved. The problem is that one is to quickly transfer the heat energy of the heat source to the radiator through the heat conduction component to the heat dissipation component that is in contact with the refrigerant (air or water); There are two factors for the exchange effect, one is the size of the contact area with the refrigerant, and the other is the difficulty of the circulation of the refrigerant around the radiator

[0003] Existing radiators are mainly divided into two types. One is that the heat conduction part and the heat dissipation part are integrally made of the same material, such as extruded aluminum profiles, die-cast aluminum, and die-cast iron radiators, which are suitable for non-concentrated heat sources (that is, heat sources The area is relatively large), the advantage is that the heat conduction part and the heat dissipation part are integrated, and the heat conduction speed is fast, but the disadvantage is that due to the limitation of the process conditions, the heat dissipation part can only be made into a sheet, and cannot be made into other shapes. It can only be improved by increasing the heat dissipation area. Heat dissipation efficiency, resulting in doubled weight and more material consumption, and the air flow performance is not ideal

The other is that the heat-conducting part and the heat-dissipating part are not integrally made. Usually, the heat-conducting part is made of a material with a faster heat conduction speed (such as a heat pipe), while the heat-dissipating part is made of a material with a lower cost (such as aluminum foil). This type of radiator is mainly The heat pipe plus fin radiator is mainly suitable for centralized heat sources (such as computer CPUs) or heat sources and heat dissipation in different spaces (such as air-conditioning heat sources outside and heat dissipation indoors). This heat dissipation structure has the following defects: 1. Heat to the blades The heat conduction is limited by the contact method and material difference; 2. The direction of heat dissipation is one-way heat dissipation from close to the heat source to the far end. The heat is easy to accumulate near the heat source, and the uneven heat distribution affects the heat dissipation efficiency; The air flow method takes away heat, and the structure is not conducive to heat exchange through air convection
