Title:
HEAT EXCHANGE DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/080757
Kind Code:
A1
Abstract:
A heat exchange device, comprising a heat exchanger main body (2) and a temperature regulation assembly (1); when the temperature of an oil that flows into a valve cavity is higher than or equal to a preset temperature, the elastic potential energy of a memory spring (12) of the temperature regulation assembly (1) is activated, and the oil enters a heat exchange channel (2f) for heat exchange; otherwise, the oil directly flows out of the heat exchanger main body (2) by means of a bypass channel (2e) without passing through a heat dissipation assembly (21); the thermal reaction of the memory spring (12) is fast and response time is short, greatly improving the operating performance and usage safety of a transmission; moreover, the memory spring (12) is small in size, and has higher installation stability, while cooperative use with other parts is not necessary, thus simplifying the structure of the temperature regulation assembly (1), and greatly reducing the size of the temperature regulation assembly (1); the temperature regulation assembly (1) may be installed at the position of a fluid inlet of a plate heat exchanger, the two being integrated into a comprehensive design, and thus on-site installation is not required, increasing installation efficiency, greatly reducing the space occupied in a vehicle, and being beneficial in optimizing overall vehicle design.
