Problems solved by technology

Various radiators have their own advantages and disadvantages: the processing technology of the round tube assembly radiator is simple and the cost is low; the processing technology of the oval tube assembly radiator and the flat tube assembly radiator is more complicated, the performance is good but the cost is high
[0006] Due to the existence of the poor heat dissipation area 30, the further improvement of the heat exchange efficiency of the radiator is hindered, and the heat dissipation performance of the radiator is difficult to be brought into full play.

Embodiment 1

[0028] The basic structure of the interlaced tube assembled radiator of the present invention is the same as the prior art, and mainly includes a first water chamber, a second water chamber and a radiator core. The first water chamber is provided on the upper side of the radiator core, and the second water chamber is provided on the lower side of the radiator core. The heat dissipation core is sealed with the first water chamber and the second water chamber through an undercut process to form a sealed liquid passage to form a complete assembled radiator. The connection relationship of the above three components is in the prior art, and will not be repeated here.

[0029] Such as image 3 As shown, the radiator core is composed of a plurality of radiating fins 20 and a plurality of radiating pipes 10 passing through the radiating fins 20. The heat dissipation tube 10 and the heat dissipation fin 20 are connected into one body through a tube expansion process, and then the heat di...

Embodiment 2

[0045] Such as Figure 5 , Image 6 Shown is the second embodiment of the present invention. The structure of this embodiment is basically the same as that of the first embodiment. The difference is that the heat pipe 10 is an elliptical metal tube, and, in this embodiment, there are multiple The radiating pipes 10 are connected in parallel, and are respectively connected to the first water chamber and the second water chamber.

[0046] In this embodiment, the first water chamber may also be arranged on the left side of the radiator core, and the second water chamber may be arranged on the right side of the radiator core.

[0047] This embodiment also improves the heat exchange efficiency of the radiator, and can obtain basically the same technical effects as the foregoing embodiment. Further, for the elliptical tube assembled radiator, the staggered tube-fin structure can make the force of the radiating tube in the tube expansion process uniform, reduce the influence of stress, an...

Embodiment 3

[0049] Such as Figure 7 , Picture 8 Shown is the third embodiment of the present invention. The structure of this embodiment is basically the same as that of the first embodiment, except that the heat dissipation tube 10 is a flat metal tube.

Abstract

The invention discloses a staggered pipe assembly-type radiator which comprises a first water chamber, a second water chamber and a radiator core. The radiator core comprises a plurality of radiator fins and a plurality of radiator pipes, wherein the radiator pipes penetrate through the radiator fins and are staggered on the radiator fins. In the invention, a novel radiator fin structure is adopted, the radiator pipes penetrating through the radiator fins are arranged in a staggered way, and shutters in staggered arrangement are arranged in a gap between the radiator pipes in an assistant way to thin and damage an air boundary layer on the radiator fins, enhance the air disturbance and improve the heat exchange efficiency of the radiator. The assembly-type radiator has the advantages of simple whole structure, high heat exchange efficiency, strong equipment generality, high production efficiency, and the like.

Description

Technical field [0001] The present invention relates to the technical field of heat exchangers, in particular to an assembled radiator. Background technique [0002] Automobile radiators are used to exchange heat between the cooling water heated by the engine and the air flowing into the front of the vehicle to cool the radiator. Generally, there are brazed parallel flow radiators and mechanically assembled tube-fin radiators (hereinafter referred to as: Fabricated radiator) two major categories. Due to its mature processing technology, excellent cost performance and better reliability, assembled radiators are currently widely used in medium and small displacement cars. [0003] According to the specifications of the heat pipe, the assembled radiator is divided into round tube, oval tube and flat tube assembled radiator. Different radiators have their own advantages and disadvantages: round tube assembled radiators have simple processing technology and low cost; elliptical tube a...
