Description

Technical Field

[0001] The utility model relates to the technical field of heat exchanger brazing, in particular to an integrated brazing bracket for an automobile heat exchanger. Background Art

[0002] The automobile heat exchanger is an important component in the automobile cooling system. It has two functions: heat dissipation and heating. When the engine is running, the water pump will draw the coolant from the water tank and enter the engine along the flow direction of the water pipe to cool it and take away the heat. At this time, the coolant flowing through the engine becomes hot and needs to be dissipated. At this time, the automobile heat exchanger is needed. It transfers heat to the air through the water-cooled air heat exchange method, thereby achieving the heat dissipation of the engine coolant. In addition, in winter, the car engine needs to be heated, and at this time, the coolant needs to be reheated, which is also an important function of the automobile heat exchanger.

[0003] In the prior art, the welding of automobile heat exchangers generally adopts a two-step manufacturing procedure. After the brazing process is completed, workers manually weld the automobile heat exchanger device using a manual flame, which leads to an increase in manufacturing cost and time cost. Utility Model Content

[0005] The utility model is implemented by the following technical scheme: an integrated brazing bracket for automobile heat exchanger, comprising a heat exchanger and a limiting column, the inner surface of the heat exchanger is threadedly connected with bolts, the surface of the bolts is threadedly connected with bolt fixing strips, a support pipe is placed at the bottom of the heat exchanger, the end of the limiting column is fixedly connected with a fixing pipe, the end of the fixing pipe is fixedly connected with a transverse connecting fixing pipe, the end of the transverse connecting fixing pipe is fixedly connected with a longitudinal connecting fixing pipe, the back of the heat exchanger is connected with a water pipe 1, and the back of the heat exchanger is connected with a water pipe 2;

[0006] As a further improvement of the above scheme, the number of the bolts is set to be several, and the number of the bolts is located on the inner surface of the heat exchanger. The number of the support tubes is set to be eight, and the eight support tubes are located on the surface of the fixed tubes. The number of the fixed tubes is set to be three, and the three fixed tubes are located on the surface of the transversely connected fixed tubes. The number of the transversely connected fixed tubes is set to be two, and the two transversely connected fixed tubes are located on the surface of the longitudinally connected fixed tubes.

[0007] As a further improvement of the above solution, the bolt fixing strip is located below the heat exchanger, the fixing pipe is located on the inner side of the longitudinal connecting fixing pipe, and the transverse connecting fixing pipe is located below the heat exchanger.

[0008] Through the above technical solution, by setting the bolt fixing strips and bolts, the heat exchanger can be installed and fixed, and the specific position of the heat exchanger can be adjusted, and multiple heat exchangers can be placed on the device.

[0009] As a further improvement of the above solution, a square column is fixedly connected to the upper surface of the transverse connecting and fixing tube, a connecting tube is fixedly connected to the upper surface of the square column, and a placement tube is fixedly connected to one side of the connecting tube.

[0010] As a further improvement of the above scheme, the number of the square columns is set to two, and the two square columns are located above the longitudinal connecting fixed tube. The number of the placement tubes is set to two, and the two placement tubes are located on one side of the connecting tube, and the placement tubes are located above the square columns.

[0011] Through the above technical solution, the supporting legs are provided to support the upper device to prevent shaking during use, thereby preventing the welding position from being incorrectly caused.

[0012] As a further improvement of the above solution, the front side of the transverse connecting fixing tube is fixedly connected to a limiting block, the upper surface of the transverse connecting fixing tube is fixedly connected to a fixed column, and the right side of the fixed column is fixedly connected to a limiting column.

The number of the limit columns is set to four, and the four limit columns are located on the upper surface of the transversely connected fixed tube, and the limit blocks are located below the limit columns.

[0014] Through the above technical solution, by setting the limit block and the limit column, the position of the heat exchanger can be limited during use, which can assist in the installation of the heat exchanger.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] The utility model sets a heat exchanger, places the heat exchanger on a support tube, and places a bolt fixing strip at the bottom of the support tube. The bolts are passed through the bolt fixing strip to fix the heat exchanger on the inner surface of the heat exchanger. Since the upper surfaces of the support tube and the fixing tube are parallel, the heat exchanger can be installed and fixed in a plane, so that it can be fixed at any position of the device. Multiple heat exchangers can also be installed to reduce the cost of purchasing the frame. Through the water pipe 1 and the water pipe 2 on the back of the heat exchanger, the technical effect of integrating the water pipes can be achieved during welding, and there is no need to manually flame weld the water pipes. Because the MQB product pipeline is special in shape and direction, it is necessary to keep the pipeline position unchanged in a furnace heated to above 600°C by brazing. Therefore, the stainless steel square tube of the longitudinally connected fixing pipe material is used as the bottom outer frame to ensure that the product is not deformed when placed and the product contact surface is small. The position where the product can be placed is used as a reference.

[0017] The utility model arranges square columns. On the square columns and the connecting pipes, the sizes of the square columns and the connecting pipes ensure the left-right position degree and the angle position degree of the short pipe. When the product is placed, the small pipe can be pushed onto the square columns. The connecting pipes are used to block the wind curtain in the brazing furnace during brazing. Wind curtains of corresponding specifications can be installed to prevent the product pipelines from being unqualified in position due to the wind curtains scraping the product pipelines at 600°C.

There are two transversely connected fixed tubes 6, and two transversely connected fixed tubes 6 are located on the surface of the longitudinally connected fixed tube 2.

[0028] The bolt fixing strip 15 is located below the heat exchanger 14 , the fixing pipe 4 is located inside the longitudinal connecting fixing pipe 2 , and the transverse connecting fixing pipe 6 is located below the heat exchanger 14 .

[0029] A square column 5 is fixedly connected to the upper surface of the transverse connecting and fixing pipe 6 , a connecting pipe 7 is fixedly connected to the upper surface of the square column 5 , and a placement pipe 8 is fixedly connected to one side of the connecting pipe 7 .

[0030] There are two square columns 5 , which are located above the longitudinally connected fixing tube 2 ; there are two placement tubes 8 , which are located on one side of the connecting tube 7 , which are located above the square columns 5 .

[0033] The implementation principle of an integrated brazing bracket for an automobile heat exchanger in the embodiment of the present application is as follows: by placing the heat exchanger 14 on the support tube 3, a bolt fixing strip 15 is placed at the bottom of the support tube 3, and the bolt 1 passes through the bolt fixing strip 15 to fix it on the inner surface of the heat exchanger 14.
