Variable flow heat exhanger

A variable flow heat exchanger, comprising:

• a housing including a first housing and a second housing;
• a heat exchange core is arranged between the first housing and the second housing, the heat exchange core formed by superposition of multi-layer heat exchange plates;
• a cooling fluid interface arranged on the first housing;
• a cooled fluid interface arranged on the second housing, the cooled fluid interface including a first interface, a second interface, and a third interface;
• wherein, in a first state, a cooled fluid flows into the heat exchange core from the first interface, and flows out of the second interface after heat exchange through a plurality of fluid flow channels of each layer of heat exchange plates of the heat exchange core;
• wherein, in a second state, the cooled fluid flows into the heat exchange core from the first interface and the second interface respectively, and flows out of the third interface after heat exchange through the plurality of fluid flow channels of each layer of heat exchange plates of the heat exchange core.
