Heat exchange structure and heat exchange integrated device and engine oil heat exchange system

Abstract

A heat exchange structure, a heat exchange integrated device and an engine oil heat exchange system relate to the technical field of heat exchange. The heat exchange structure includes a heat exchange base and a heat exchanger; a closed heat exchange cavity is formed between the heat exchange base and the connecting shell; the heat exchanger is arranged in the heat exchange cavity, and the heat exchanger and the heat exchange base The heat exchanger is provided with a heat exchange inner flow channel and a raw liquid flow channel that are not connected to each other; the heat exchange base is provided with a raw liquid inlet and a raw liquid outlet that communicate with the raw liquid flow channel, and is also provided with a heat exchange inner flow channel. The heat exchange outlet is communicated; the heat exchange cavity outside the heat exchanger is the heat exchange outer flow channel; the heat exchange inner flow channel is communicated with the heat exchange outer flow channel. Both the heat exchange integrated device and the engine oil heat exchange system include a heat exchange structure. The purpose of the present invention is to provide a heat exchange structure, a heat exchange integrated device and an engine oil heat exchange system, so as to solve the problem in the prior art that the heat exchange performance in a small heat exchange space is difficult to satisfy the heat dissipation to a certain extent. requested technical issues.

Description

technical field [0001] The invention relates to the technical field of heat exchange, in particular to a heat exchange structure, a heat exchange integrated device and an engine oil heat exchange system. Background technique [0002] In the previous oil cooler design, the form of the cooler is selected according to the engine body structure and the heat dissipation performance required by the customer; the plate-fin oil cooler and the box-type oil cooler are the two types of the existing oil cooler. a common form. [0003] like figure 1 As shown, the plate-fin oil cooler (also called water bath oil cooler) is assembled in the water cavity formed by the oil cooler base 1 and the engine block 2; figure 1 The direction of the arrow in is the flow direction of coolant and oil. Among them, the cooling liquid flow mode: the cooling liquid flows into the water cavity from the water inlet 6 provided on the engine block 2, passes through the outer space of the oil cooler 3, exchan...
