Abstract

The invention relates to a counter flow type radiator and a manufacturing method thereof. The structure is particularly suitable for devices with ordinary heating requirements. The counter flow type radiator comprises a cooling pipe, cooling fins and an electric heat pipe. The cooling pipe is provided with an electric heat pipe installing hole. Shrinkage joints are arranged in the cooling pipe installing hole. The electric heat pipe is installed in the electric heat pipe installing hole. The cooling fins are arranged outside the cooling pipe. Compensation shrinkage joints are reserved in the cooling fins. The manufacturing method of the counter flow type radiator comprises the steps that firstly, an aluminum sectional bar is adopted to be machined into the cooling pipe, the electric heat pipe installing hole is reserved in the middle of the cooling pipe, and the shrinkage joints are reserved in the electric heat pipe installing hole; secondly, the cooling fins are manufactured above and below the cooling pipe, and the compensation shrinkage joints are reserved in the length direction of the cooling fins; and thirdly, the electric heat pipe is installed and installed in the electric heat pipe installing hole in the middle of the cooling pipe, the electric heat pipe and the electric heat pipe installing hole are in close contact evenly through compression, a compression die is used through a press, the electric heat pipe installing hole formed in the middle of the cooling pipe is pressurized and wraps an electric heat pipe body, the electric heat pipe body and the electric heat pipe installing hole are in close contact evenly through compression, and the counter flow type radiator is manufactured.

Description

technical field [0001] The invention relates to a convection radiator and a manufacturing method thereof, and the structure is especially suitable for devices requiring general heating. Background technique [0002] At present, it is difficult for various single-fin and multi-fin heat sinks to pass through the heating wire to fill the powder, the diameter of the tube cannot be uniformly shrunk, and the heat-conducting insulating powder in the tube cannot be compressed to the process requirements, the density consistency is poor, and the external unit power load is small. There are many manufacturing processes and the process method is complicated. Moreover, there are many manufacturing processes for the heat sink body, and the process method is complicated. Another example is the combination of piercing methods, and the connection between the electric heating tube and the heat sink is not tight. The thermal conductivity is weakened and the processing is complicated. In ad...
