Radiating pipe

Technical Field

Background

The heat dissipation module generally comprises several types of components such as a water radiator, an intercooler, an oil radiator, an air conditioning system and the like, and the heat dissipation principle of the several types of radiators is to realize heat exchange through a radiator core. The cooling medium flows in the radiator core, and the air flow takes away heat from the outside through the radiator core, so that the aim of continuous heat exchange is fulfilled. The heat dissipation pipe is an important component of the heat dissipation core, and the cooling medium flows in the heat dissipation pipe and passes through the pipe wall to realize heat exchange with the external air. The cooling tube has multiple types such as single channel, multichannel, combination passageway, and wherein current multichannel cooling tube, its shortcoming is: the conventional extrusion type multi-channel radiating pipe is difficult to realize concave point turbulence; the vertex of the concave rib of the existing welded multi-channel radiating pipe is arc-shaped, and the arc-shaped concave rib is in line contact during butt joint, so that the welding is insufficient, dislocation cold welding is easy to generate, and the welding strength is low; the existing concave points are circular, are not in butt contact, have unobvious turbulence effect, and do not improve the compressive strength of the radiating pipe.

Disclosure of Invention

In order to solve the technical problems, the utility model provides a radiating pipe, which adopts the technical scheme that:
