Radiator built-in plate-fin oil cooler

Abstract

The invention discloses a radiator built-in plate-fin oil cooler and belongs to the field of automobile powertrain cooling systems. The radiator built-in plate-fin oil cooler comprises an oil collecting chamber and further comprises at least two heat dissipation plates and oil cooler connectors. All the heat dissipation plates are connected with the oil collecting chamber, and the oil cooler connectors are arranged at the two ends of all the heat dissipation plates. The at least two heat dissipation plates are arranged in a radiator water tank. At least one row of fins are arranged between every two adjacent heat dissipation plates of the at least two heat dissipation plates. After penetrating through an oil cooler oil opening in a radiator, one ends of the oil cooler connectors are fixedly connected with all the heat dissipation plates correspondingly. The other ends of the oil cooler connectors are arranged outside the oil cooler oil opening. According to the radiator built-in plate-fin oil cooler provided by the invention, under the circumstance that the space of the radiator water tank is not changed, the oil cooler connectors and the oil cooler can be assembled separately, in this way, the size of the radiator water tank can be made smaller, and the heat dissipation fins can further be added between every two adjacent formed aluminum plates.

Description

technical field [0001] The invention relates to the field of automotive powertrain cooling systems, in particular to a plate-fin oil cooler with a built-in radiator. Background technique [0002] In recent years, consumers have higher and higher requirements for the comfort and handling performance of cars. Among them, the automatic transmission is more and more widely used because of its smooth shifting and convenient and simple operation. However, due to the existence of a certain shifting impact in the operation of the manual transmission and the need for the operator to have corresponding skills, more and more disadvantages have emerged. [0003] A large number of operating mechanisms in automatic transmissions are driven by hydraulic systems, so the heat generated by automatic transmissions is much greater than that of manual transmissions, so a transmission oil cooler is required to cool the transmission. The transmission oil cooler can not only cool the transmission...

AI Technical Summary

Problems solved by technology

[0006] At present, most of the plate-fin oil coolers with built-in radiators on the market braze the oil cooler joints with the oil cooler body, which greatly increases the external boundary conditions of the oil cooler. When assembling with the radiator water chamber , the radiator water chamber needs to have a large enough space for assembly; and when the oil cooler is assembled, because the oil cooler joint occupies part of the volume of the radiator water chamber, the radiator water chamber can only accommodate the oil tank composed of four radiator plates. cooler
