[0002] Car heaters were first produced in Europe in the 1940s, and were mainly used to preheat engines in winter and to heat truck cabs or passenger car cabins. In the existing car heater core brazing frame brazing process, the workpiece is usually fixed on a brazing tool and placed in a tunnel-type nitrogen-protected brazing furnace. The workpiece is heated by hot air in the brazing furnace, and when the solder reaches its melting point, the solder melts and welds the workpieces together.

[0003] In the production process of automobile heater core, an automobile heater core brazing frame is needed. After the heater core in the prior art is assembled by an assembly machine, the core needs to be sent to a brazing furnace for welding. When sending it in, the core is placed on a tray, and the traditional tray lacks a positioning effect, which requires the core to be bundled and fixed with iron wire. However, the iron wire bundling is not only wasteful, but also has a non-standard size. Moreover, after welding is completed, the iron wire needs to be removed, which increases the labor intensity of the staff and seriously affects the use quality of the brazing frame. It cannot meet the use requirements. Therefore, a double-layer brazed automobile heater core brazing frame with a brazing cover plate is proposed to solve the above-mentioned problems. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a double-layer brazing frame for automobile heater core with a brazing cover plate, which has the advantages of good positioning effect and strong practicality, etc., and solves the problem that after the heater core in the prior art is assembled by an assembling machine, the core needs to be sent into a brazing furnace for welding, and the core is placed on a pallet when being sent in, while the traditional pallet lacks a positioning effect, which requires the core to be tied and fixed with iron wire. However, the iron wire bundling is not only wasteful, but also has non-standard bundle sizes, and after welding is completed, the iron wire needs to be removed, which increases the labor intensity of the staff, seriously affects the use quality of the brazing frame, and cannot meet the use requirements.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a double-layer brazed automobile heater core brazing frame with a brazing cover plate, comprising two support frames, a plurality of horizontal plates fixedly connected between the two support frames, and a plurality of wall plates fixedly connected to the top of the horizontal plates;

[0006] A number of mounting brackets are fixedly connected between the transverse plate and the city wall plate, and the mounting brackets are evenly spaced and distributed between the transverse plate and the city wall plate.

[0007] Furthermore, a number of core support ribs are fixedly connected to the tops of the plurality of mounting brackets, and the plurality of core support ribs are evenly spaced and distributed on the tops of the plurality of mounting brackets.

[0008] Furthermore, the core support rib is a solid rectangular parallelepiped, and a plurality of through holes are formed inside the core support rib.

[0009] Furthermore, a connection groove is provided at the connection between the wall panel and the mounting bracket, and the wall panel and the mounting bracket are staggered and fixed.

[0010] Furthermore, the tops of the two support frames are detachably connected with brazing cover plates, and the interiors of the support frames are provided with limiting grooves adapted to the brazing cover plates, and the brazing cover plates are in abutment with the limiting grooves.

[0011] Furthermore, the brazing cover plate is a hollow frame type, and the outer diameter of the brazing cover plate is adapted to the cross-section of the two transverse plates.

[0012] Furthermore, a number of first reinforcing ribs are fixedly connected to the inside of the brazing cover plate, and a number of second reinforcing ribs are fixedly connected to the outside of the first reinforcing ribs.
