Abstract

The utility model belongs to the technical field of the heat pipe, and relates to an integral fabrication double-feather-wing copper heat pipe. The utility model comprises a heat pipe and feather wings, the feather wings are arranged on the two sides of the heat pipe, the structure of the heat pipe and the feather wings are integral structures without junction plane, the heat conduction efficiency of the heat pipe is improved up to 20 percent to 30 percent, the welding material, the equipment, the work-time utilization rate can be saved, and the production cost can be reduced, the utility model has the advantages that the structure is simple, the strength is high, the heat resistance is small, and the heat transfer as well as the heat absorption efficiency are high, the utility model can be utilized as normalized and serialized pipe product, widely used for a solar energy absorber plate, a radiator and a condenser, and arranged on other products which are required to adopt a copper heat pipe as heat exchanger.

Description

Integrated double-fin heating copper tube

Technical field

The utility model belongs to the hot pipe technique field, relates to a kind of integrated double-fin heating copper tube.

Background technology

Heat pipe is the critical component of solar absorber plate and radiator, condenser.One of heat pipe structure of the band wing that Fig. 1 uses for existing solar absorber plate is promptly welded together by copper strips and copper pipe, constitutes the wing 2 of heat pipe 1 and both sides, utilizes wing 2 increase endotherm areas at sunshine.The wing heat pipe cost of manufacture height of this split welding, intensity is low, and wing and heat pipe driving fit fully contact, and make the thermal resistance increase in the heat transfer process, influence heat transfer efficiency.

Summary of the invention

The purpose of this utility model is to provide a kind of thermal resistance little, thermal efficiency height, the double fin copper heat pipe of global formation.

The technical solution adopted in the utility model: a kind of integrated double-fin heating copper tube, comprise heat pipe, wing, wing is distributed in the heat pipe both sides, it is characterized in that heat pipe and wing are an overall structure.The cross section of two wings is a word shape.The heat pipe outer diameter D is Φ 6-60mm, and wall thickness δ is 0.5-2mm; The wing width B is 30-200mm, and thickness H is 0.25-2mm.

Heat pipe of the present utility model and wing global formation, do not have faying face, the heat conduction efficiency of heat pipe has improved 20-30%, saves welding material, equipment, the rate of utilization of work hour, reduce cost of manufacture, the utility model is simple in structure, the intensity height, and thermal resistance is little, heat transfer, heat absorption efficiency height, can be used as specification series tubing, be widely used in solar absorber plate, radiator, condenser, and other need adopt the copper heat pipe to install and use as the product that heat exchanger uses.

The specific embodiment

Consult shown in Figure 2, a kind of integrated double-fin heating copper tube, mainly constitute by heat pipe 1, wing 2, its heat pipe 1 is an overall structure with wing 2, and two wings 2 are distributed in heat pipe 1 both sides, and its cross section is a word shape, heat pipe 1 outer diameter D is Φ 6-60mm, heat pipe 1 wall thickness δ is 0.5-2mm, and wing 2 width B are 30-200mm, and wing 2 thickness H are 0.25-2mm.Because heat pipe 1 is an overall structure with wing 2, thermal resistance is very little, is used for solar heat pipe and can makes heat-conduction-type become the heat radiation type, thermal efficiency height.
