Heat exchanger, heat dissipation module, and compute device

A heat dissipation module, comprising:

• a first heat exchange portion and a second heat exchange portion, wherein the first heat exchange portion comprises a heat exchanger, an inlet of the first heat exchange portion is connected to an outlet of the second heat exchange portion, an outlet of the first heat exchange portion is connected to an inlet of the second heat exchange portion;
• and
• a power component disposed on a pipeline between the outlet of the first heat exchange portion and the inlet of the second heat exchange portion;
• wherein the heat exchanger comprises:
• a first housing having at least two chambers,
• a second housing having at least one cavity, and
• a main body portion comprising at least two flow channel portions, wherein the first housing and the second housing are fastened to two end portions of the main body portion,
• an inlet of the heat exchanger communicates with one chamber, an outlet of the heat exchanger communicates with another chamber or the at least one cavity, and each flow channel portion communicates with one of the at least two chambers and one of the at least one cavity, so that a heat exchange medium flowing in through the inlet is able to sequentially flow through the flow channel portions and then flow out from the outlet.

A compute device, comprising:

• a heat generation component;
• and
• a second heat exchange portion configured to perform heat exchange with the heat generation component, wherein the heat dissipation module comprises:
• a first heat exchange portion and a second heat exchange portion, wherein the first heat exchange portion comprises a heat exchanger, an inlet of the first heat exchange portion is connected to an outlet of the second heat exchange portion, an outlet of the first heat exchange portion is connected to an inlet of the second heat exchange portion, and
• a power component disposed on a pipeline between the outlet of the first heat exchange portion and the inlet of the second heat exchange portion,
• wherein the heat exchanger comprises:
• a first housing having at least two chambers,
• a second housing having at least one cavity, and
• a main body portion comprising at least two flow channel portions, wherein
• an inlet of the heat exchanger communicates with one chamber, an outlet of the heat exchanger communicates with another chamber or the at least one cavity, and each flow channel portion communicates with one of the at least two chambers and one of the at least one cavity, so that a heat exchange medium flowing in through the inlet is able to sequentially flow through the flow channel portions and then flow out from the outlet.
