Automotive heat exchanger radiating tube

Abstract

The invention relates to the technical field of automotive parts and discloses an automotive heat exchanger radiating tube, comprising a radiating tube body. The radiating tube body includes a radiating tube wall and a radiating cavity; the head and tail of the radiating tube wall enclose the radiating cavity; the head and tail of the radiating tube are folded toward the radiating cavity to form first and second vertical posts; the tail ends of the first and second vertical posts are fixed to the inner wall of the radiating cavity; the radiating cavity is divided into two radiating sub-cavities; the radiating tube wall is folded toward the radiating cavity to form folding connection structures; at least one folding connection structure is arranged in each radiating sub-cavity; the tail ends of the folding connection structures are fixed to the inner wall of the radiating cavity; the folding connection structures and the first and second vertical posts are all arranged in parallel. Theautomotive heat exchanger radiating tube helps effectively improve reliability of an automotive heat exchanger.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a radiating pipe of an auto heat exchanger. Background technique [0002] The automobile heat exchanger is a heat exchange body. During the operation of the whole vehicle, the operating temperature of the engine must be within a temperature range to work normally. A heat exchange device is needed to take away the heat generated during the working process in time to reduce temperature to ensure the normal operation of the engine. The radiator pipe of the automobile heat exchanger is an important part of the engine heat exchange device. Its setting determines the reliability. With the development of the automobile industry, the engine power continues to increase. Due to the problem of poor performance, it is increasingly unable to meet the heat dissipation requirements of the engine.

The radiator pipe of the automobile heat exchanger is an important part of the engine heat exchange device. Its setting determines the reliability. With the development of the automobile industry, the engine power continues to increase. The problem of poor performance is increasingly unable to meet the heat dissipation requirements of the engine

[0003] Chinese invention patent application (publication date: April 13, 2016, publication number: CN105486114A) discloses a radiator pipe-reinforced automotive heat exchanger. , and the turbulent inner fin inside the middle cooling pipe, one end of the connecting pipe is placed inside or outside the middle cooling pipe, and connected with the middle cooling pipe, and the other end of the connecting pipe is connected with the main board, and the wall thickness of the connecting pipe is at least the thickness of the short surface The thickness of the heat pipe is greater than that of the middle heat pipe. This invention improves the strength of the overall structure of the heat exchanger by only strengthening a few key parts locally, but does not improve the heat pipe itself, and the strength of the heat pipe itself does not change. Strengthening regardless of weak points, so the improvement of the overall structural strength of the heat exchanger is limited

[0004] Chinese invention patent application (publication date: May 31, 2017, publication number: CN106767101A) discloses a fin for a heat exchanger and a heat exchanger. The fin includes a fin body, and the fin body includes a plurality of straight plate parts and A plurality of connecting parts, a plurality of straight board parts and a plurality of connecting parts are arranged alternately, and the adjacent straight board parts are sealed and connected with the connecting parts, and the shape of the cross section of the fin main body is in a roundabout shape, and the two adjacent straight board parts are located at the The connecting part between the two straight plate parts forms a channel for the flow of the medium, and the straight plate part is provided with concave-convex structure reinforcing ribs. The fins for the heat exchanger do not need to design a window structure during the processing process, and there is no louver structure. When the medium flows in the channel of the fin main body, it is not easy for dust to accumulate in the channel of the fin main body, and it is not easy to affect the flow of the medium in the channel, and it is not easy to affect the heat transfer amount and heat transfer efficiency. It is suitable for the cooling tube of the automobile heat exchanger Fins and the outer fins of the heat pipe, but it is a lot of work to build the fin body into the heat pipe, and it cannot improve the reliability of the heat pipe
