The fins 3 are superimposed on each other. This arrangement can increase the heat dissipation area and enhance heat transfer.
本实施例中,鳍片3上设有第一通孔31,散热管2穿设于第一通孔31内。这样设置使得散热管2与鳍片3紧密接触,减少传热路径,提高传热速度。In this embodiment, the fin 3 is provided with a first through hole 31, and the heat dissipation tube 2 is penetrated through the first through hole 31. This arrangement makes the heat dissipation tube 2 and the fins 3 closely contact, reducing the heat transfer path and increasing the heat transfer speed.

This arrangement not only reduces the liquid evaporation temperature, but also allows the liquid flow and gas flow to flow smoothly, thereby improving the heat exchange efficiency.
另外,板管主体1为中空的圆柱结构;散热管2的管长度大于板管主体1的管长度。将板管主体1设置为中空的圆柱结构,能增加板管主体1与热源接触的表面积,以提高从热源吸收的热量的量;在高度方向上每个散热管2的管长度大于板管主体1的管长度,这一设置使得冷凝路径较长,便于提高换热效果。In addition, the plate tube body 1 has a hollow cylindrical structure; the tube length of the heat dissipation tube 2 is greater than the tube length of the plate tube body 1. Setting the plate tube body 1 as a hollow cylindrical structure can increase the surface area of the plate tube body 1 in contact with the heat source to increase the amount of heat absorbed from the heat source; the length of each heat dissipation tube 2 in the height direction is greater than the plate tube body The tube length of 1, this setting makes the condensation path longer, which is convenient for improving the heat exchange effect.
