[0002] The structure of a parallel flow oil cooler is as Figure 1 shown, and generally includes a heat dissipation core body A. A manifold B is respectively installed, spliced and fixed in the grooves at the left and right ends of the heat dissipation core body A. A pipe one C is connected through and at the rear end of the manifold B on the left side, and a pipe two D is connected through and at the front end of the manifold B on the right side. The right end of the pipe one C and the pipe two D are connected together through a bracket E located therebetween. The assembly and processing process of the parallel flow oil cooler includes multiple processing procedures. Among them, the heat dissipation core body and the manifolds are usually assembled and spliced on a special assembly device, and then the assembled and spliced heat dissipation core body and manifolds are transported to a brazing furnace for subsequent processing. During the process of transporting the assembled and spliced heat dissipation core body and manifolds from the assembly device to the brazing furnace, it is inevitable that component misalignment, part dropping, or even disassembly occurs. This not only affects the brazing processing efficiency of the heat dissipation core body and the manifolds, but also causes part deformation and affects product quality. It not only increases the product cost, but also causes waste of material resources and human resources. For this reason, the utility model provides a furnace passing tooling for an oil cooler in order to solve the above technical problems. Summary of the Invention

[0003] The purpose of the utility model is to overcome the defects existing in the prior art and provide a furnace passing tooling for an oil cooler. After the heat dissipation core body and two manifolds are assembled on the assembly device, the furnace passing tooling of the utility model is used to transport them to the brazing furnace. Among them, the heat dissipation core body, side strip one and side strip two are clamped and fixed inside a first clamping groove at the lower ends of several vertical plates of the furnace passing tooling, and the furnace passing tooling is turned 180° for transportation. This can not only fasten the heat dissipation core body and the side strips, but also play a protective role for the heat dissipation core body and the manifolds, preventing component misalignment, dropping, or even disassembly caused by vibration during transportation, ensuring the smooth progress of the oil cooler furnace passing brazing operation, helping to improve the production and processing efficiency and product quality stability of the parallel flow oil cooler, and thus helping to save product processing costs and human resource costs; the overall structure design is simple, the preparation and implementation feasibility is high, and the practicability is strong.
