Problems solved by technology

[0003] 1. When the width of the heat pipe is greater than 26mm, the inner wall of the pipe is easily deformed due to the increase in pressure, which is easy to cause leakage and affects the welding surface area, thereby reducing the heat transfer performance
[0004] 2. The investment in high-frequency welded pipe equipment is large, and a pipe-making machine needs more than 10 million yuan
[0005] 3. The production cost is high, and the spare parts of the high-frequency welding head and the capital investment of high-grade volatile oil increase the production cost of the high-frequency welded pipe.
[0006] 4. The production scrap rate is high, because the seam quality of high-frequency welding is affected by many factors, it is easy to produce defects such as inclusions and virtual welds, resulting in a scrap rate of 21% during the flaw detection inspection after tube production

Embodiment

[0024] Such as Figure 1-2 As shown, a B-type tube aluminum tube belt type water tank radiator includes a heat dissipation pipe, a heat dissipation belt, a side plate and a main piece, and the heat dissipation pipe 1 is a B-type tube, and the B-type tube is folded in the middle The heat pipe is separated into two cavities: a cavity 2 and b cavity 3, so that the liquid circulates in two independent through cavities (a cavity 2 and b cavity 3), and the cladding layer is on the outside with the heat dissipation belt Connected, and the inner side is a smooth surface. The heat generated during the working process forms heat exchange with the outside through the heat dissipation belt connected to it, so as to improve the heat exchange efficiency.

[0025] In order to make the shape of the B-shaped tube not be affected by the width of the coil material, the middle rib adopts an overlapping angle structure. This also improves the weld strength of the ribs. In order to ensure the qua...

Abstract

The invention relates to a B-shaped aluminum tube belt type heat radiator for a water tank. The heat radiator comprises a heat radiating tube, a heat radiating belt, a side plate and a main fin, wherein the heat radiating tube is a B-shaped tube; the heat radiating tube is divided into two cavities by using the folding part in the middle of the B-shaped tube, so that liquid separately flows in two separate cavities; and a coating layer of the B-shaped tube is connected with the heat radiating belt at the outer side; and the inner side of the B-shaped tube is a shiny surface. Compared with the prior art, the B-shaped aluminum tube belt type heat radiator has the advantages of low cost, favorable heat transfer performance, high intensity and the like.

Description

technical field [0001] The invention relates to a radiator, in particular to a B-shaped tube aluminum tube belt radiator for a water tank. Background technique [0002] At present, the heat pipe of the aluminum pipe belt water tank mainly adopts high-frequency welded pipe, but there are the following technical difficulties and shortcomings in the production of the product: [0003] 1. When the width of the heat pipe is greater than 26mm, the inner wall of the pipe is easily deformed due to the increase in pressure, which is easy to cause leakage and affects the welding surface area, thereby reducing the heat transfer performance. [0004] 2. The investment in high-frequency welded pipe equipment is large, and a pipe-making machine needs more than 10 million yuan. [0005] 3. The production cost is high, and the spare parts of the high-frequency welding head and the capital investment of high-grade volatile oil increase the production cost of the high-frequency welded pipe. ...
