Embodiment 1

[0042] Such as figure 1 As shown, the radiating pipe of the heat exchanger provided by Embodiment 1 of the present invention includes a pipe body 10 and a dimple 20 provided on the outer wall of the pipe body 10; the dimple 20 includes a plurality of dimples extending in a strip shape; The extending direction of the pit is arranged at an acute or obtuse angle with the extending direction of the pipe body 10 , and a plurality of pits are arranged at intervals along a predetermined direction, and the predetermined direction intersects with the extending direction of the pipe body.

[0043] In this embodiment, in order to ensure a better turbulent flow effect, a plurality of dimples 20 are generally arranged on the outer wall of the pipeline body 10, and the dimples in the dimples 20 extend toward the inner wall of the pipeline body 10, and the pipe body The inner wall of 10 forms a bulge. When the medium flows in the pipe body 10, under the premise of ensuring the general convey...

Embodiment 2

[0059] Such as figure 2 with image 3 As shown, the heat exchanger radiating tube provided by Embodiment 2 of the present invention includes a pipe body 10 and a dimple 20 disposed on the outer wall of the pipe body 10; the dimple 20 includes a plurality of dimples extending in a strip shape; The extending direction of the pit and the extending direction of the pipe body 10 are set at an acute or obtuse angle. At least one of the plurality of pits is the first pit 21 , and at least the other is the second pit 22 , and an angle β is formed between the extending direction of the first pit 21 and the extending direction of the second pit 22 .

[0060] In this embodiment, in order to ensure a better turbulent flow effect, a plurality of dimples 20 are generally arranged on the outer wall of the pipeline body 10, and the dimples in the dimples 20 extend toward the inner wall of the pipeline body 10, and the pipe body The inner wall of 10 forms a bulge. When the medium flows in t...

Embodiment 3

[0086] The main structure of the third embodiment is the same as that of the second embodiment, the difference is that the third embodiment involves the specific structure of the pipe body 10 and the specific arrangement of the dimple 20 on the pipe body 10 . Specifically, as Figure 4 to Figure 6 As shown, the dimple part 20 is arranged at an acute angle or an obtuse angle to the conveying direction of the medium; A plurality of dimples 20 arranged at intervals in the extending direction. In this embodiment, both the upper wall and the lower wall of the pipe body are provided with dimples, which can make the flow of the medium more turbulent and improve the heat exchange performance.

[0087] Wherein, the dimple part on the upper wall is the upper dimple part 1, and the dimple part on the lower wall is the lower dimple part 2, and the upper dimple part 1 and the lower dimple part 2 can be completely oppositely arranged, and also can be partly relative settings.

Abstract

The invention relates to the technical field of heat exchange devices, in particular to a heat exchanger radiating pipe and a heat exchanger. The heat exchanger radiating pipe comprises a pipeline body and a pit part arranged on the outer wall of the pipeline body; the pit part comprises at least one pit in strip-shaped extending; and the extending directions of the pits are arranged at an acute angle or an obtuse angle with the extending direction of the pipeline body. Due to the fact that the extending directions of the pits are arranged at the acute angle or the obtuse angle with the extending direction of the pipeline body, the extending directions of the pits are avoided to be perpendicular to the extending direction of the pipeline body, then the flowing resistance of a medium can bereduced, so that the damage to a pump caused by bubbles which are caused by the high pressure loss is avoided, and the reliability of a system can not be influenced due to the fact that the working pressure of the system is increased which is caused by higher pressure loss. Moreover, the pits are in strip-shaped extending and are obliquely arranged relative to the extending direction of the pipeline body so that a vortex can be formed more easily, forming of a turbulent flow by the medium in the pipeline body is more facilitated, and therefore the heat exchange performance is improved.

Description

technical field [0001] The invention relates to the technical field of heat exchange devices, heat exchanger cooling pipes and heat exchangers. Background technique [0002] The heat exchanger cools the engine oil through the cooling water. Its working principle is that the coolant flows through the water side channel of the cooler to cool the right channel, and uses the heat exchange principle to cool the high temperature engine oil in the core plate to reach the ideal temperature range. The heat exchanger includes a core, and the core includes a plurality of mutually superimposed and fixed heat dissipation pipes, and each heat dissipation pipe includes a plurality of pipes for medium circulation. [0003] At present, in order to increase heat dissipation, the cross-sectional area of ​​the pipe is usually increased to increase the flow rate of the medium in the pipe, but there is a problem that when the medium is in a low flow rate state, laminar flow is likely to occur, re...
