Problems solved by technology

However, when the actual vehicle cooling system operates under different working conditions, the flow rate of the internal medium will vary greatly. The current conventional oil cooler design cannot change its own process according to the system flow change, resulting in a decrease or increase in the cooling efficiency of the cooler. energy consumption

Abstract

The invention discloses a variable flow type heat exchanger and a power assembly, and belongs to the technical field of automobile parts. A variable flow type heat exchanger comprises a shell, a first heat exchanger and a second heat exchanger, the heat exchange core body is arranged between the first shell and the second shell, and the heat exchange core body comprises a plurality of layers of heat exchange plates; the cooled fluid interface comprises a first interface, a second interface and a third interface; in the first state, cooled fluid flows into the heat exchange core body from the first connector, and flows out from the second connector after being subjected to heat exchange through fluid flow channels of all layers of heat exchange plates of the heat exchange core body. And in the second state, the cooled fluid flows into the heat exchange core body from the first connector and the second connector, and flows out from the third connector after heat exchange. A powertrain includes a variable flow heat exchanger. By means of the mode switching mode, the function of changing the internal flow is achieved, and the requirements of different operation working conditions for the cooler are met.

Description

technical field [0001] The application belongs to the technical field of auto parts, relates to coolers, and in particular relates to a variable flow heat exchanger and a power assembly. Background technique [0002] At present, the conventional vehicle oil coolers on the market mostly use plate-fin oil coolers, whose function is to disturb the hot oil flowing in the core and the fins through the structural design of the core and the fins. The cooling water and the oil are used for heat exchange and cooling, so as to cool the oil and keep it in a suitable temperature range to ensure that the engine oil has sufficient viscosity and maintain the lubrication of the relevant engine moving parts. [0003] In the existing vehicle oil coolers, the designed fluid circulation modes are all single, that is, the inlet, outlet and flow direction of the flowing medium are all fixed. However, when the actual vehicle cooling system operates under different working conditions, the flow rat...
