Aluminum pipe for automotive air-conditioning heat radiator

Abstract

The invention discloses an aluminum pipe for an automotive air-conditioning heat radiator. The aluminum pipe for the automotive air-conditioning heat radiator comprises a flat aluminum pipe, an anti-oxidation layer is arranged on the outer surface of the flat aluminum pipe, a heat-conducting graphite film is arranged on the inner surface of the flat aluminum pipe, heat-radiating bulges are uniformly arranged on the surface of a pipe body of the flat aluminum pipe, and a supporting upright post is arranged inside the flat aluminum pipe; through the pipe body of the flat aluminum pipe, the space occupied by the pipe body can be effectively reduced; the supporting upright post arranged in the inner wall of the pipe body can effectively support the pipe body, so that the pipe body is difficult to damage; the heat-radiating contact surface area between a heat-radiating pipe and air is increased through the heat-radiating bulges, so that the efficiency of heat exchange between cooling liquid inside a core body and outside air is improved; the heat-conducting graphite film self has good heat-conducting performance and can also prevent the liquid inside the flat aluminum pipe from reacting with aluminum to affect the heat-conducting efficiency. The aluminum pipe disclosed by the invention is reasonable in design, simple in structure and suitable for production and popularization.

Description

technical field [0001] The invention belongs to the technical field of suction fans, and in particular relates to an aluminum tube for an automobile air-conditioning radiator. Background technique [0002] Existing car radiators are generally composed of three parts: a radiator core for cooling, a water inlet chamber and a water outlet chamber. The coolant flows in the radiator core, and the air passes through the radiator core at high speed, so that the coolant and air Heat exchange is performed through the radiator core; most of the structure of the radiator core is in the form of a round tube, which occupies a large space, and the structure is too simple and not durable. The use of the air conditioner in the car; and the material of the general heat pipe is made of metal aluminum with good thermal conductivity, but the reaction of metal aluminum with oxygen in the air or water will form an aluminum oxide film, which will affect the heat dissipation performance of the heat...

[0002] Existing car radiators are generally composed of three parts: a radiator core for cooling, a water inlet chamber and a water outlet chamber. The coolant flows in the radiator core, and the air passes through the radiator core at high speed, so that the coolant and air Heat exchange is performed through the radiator core; most of the structure of the radiator core is in the form of a round tube, which occupies a large space, and the structure is too simple and not durable. The use of air conditioners in automobiles; and the general material of the heat pipe is made of metal aluminum with good thermal conductivity. However, the reaction of metal aluminum with oxygen in air or water will form an aluminum oxide film, which will affect the heat dissipation performance of the heat pipe.
