heat sink

Abstract

The invention relates to the field of heat dissipation and provides a radiator which aims to solve the problems that an existing radiator is prone to leakage and short in service life. The radiator comprises a first main board, a second main board, two supporting boards, a plurality of heat dissipation tubes, a plurality of heat dissipation strips, a water inlet chamber and a water outlet chamber. The first main board and the second main board are parallel to each other and are cast to be of an integral structure with the heat dissipation tubes, and the heat dissipation tubes are perpendicularly connected with the first main board and the second main board. One ends of the supporting boards are perpendicularly connected with the first main board, the other ends of the supporting boards are perpendicularly connected with the second main board, and the heat dissipation tubes are located between the two supporting boards. The heat dissipation strips are arranged between two adjacent heat dissipation tubes and between the supporting boards and the heat dissipation tubes adjacent to the supporting boards. The supporting boards are provided with stress relief holes, wherein distances are reserved both between the stress relief holes and the first main board and between the stress relief holes and the second main board. The water inlet chamber is formed in the first main board, the water outlet chamber is formed in the second main board, and the water inlet chamber and the water outlet chamber are communicated through the heat dissipation tubes. The radiator can avoid the phenomenon that leakage occurs due to the fact that the heat dissipation tubes crack, and the service life is long.

Description

technical field [0001] The invention relates to the field of heat dissipation, in particular to a radiator applied to vehicles. Background technique [0002] like figure 1 As shown, in the existing radiator, the first main board 1 and the second main board 2 and the two support plates 3, the heat dissipation pipes 4 and the heat dissipation strips 5 are all connected together by welding. During the working process of the radiator, due to the frequent occurrence of thermal expansion and contraction, the first main board 1, the second main board 2, the support plate 3, the heat dissipation pipe 4 and the heat dissipation belt 5 in the radiator are prone to deformation, resulting in the support plate 3 1. The connection between the heat dissipation pipe 4 and the heat dissipation belt 5 and the first main board 1 and the second main board 2 is broken, especially the connection between the heat dissipation pipe 4 near the support plate 3 and the first main board 1 and the secon...
