Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to a graphene-based microchannel heat exchanger. Background Art

[0002] Graphene is a two-dimensional material composed of a single layer of carbon atoms with excellent thermal conductivity, high strength and excellent electrical properties. These properties make graphene an ideal material for heat conduction and heat exchange applications. Microchannel heat exchanger is a heat exchange device that achieves efficient heat transfer in a very small space. By introducing fluid into the microchannel and constructing a microchannel structure on the graphene film, the graphene-based microchannel heat exchanger can provide large surface area and high specific surface area heat exchange, achieving efficient heat transfer. In addition, the high thermal conductivity of graphene can also quickly transfer heat from the heat source to the fluid, improving the heat transfer efficiency.

[0003] Graphene microchannel heat exchangers have a wide range of applications in many fields. For example, in the heat dissipation of electronic devices, graphene microchannel heat exchangers can effectively conduct heat from high-power electronic devices to maintain a stable operating temperature of the devices; in energy recovery, graphene microchannel heat exchangers can improve energy utilization efficiency and convert low-temperature waste heat into usable energy; in chemical processes, graphene microchannel heat exchangers can realize efficient catalytic processes and chemical reaction control.

[0004] However, the currently existing graphene microchannel heat exchanger cannot filter the exchanged substances when in use, resulting in more impurities and particulate matter on the inner wall of the heat exchanger, affecting the service life and being inconvenient for maintenance. Therefore, a graphene microchannel heat exchanger with filtering effect, extended service life and convenient maintenance is proposed, so that the filtering device in the microchannel heat exchanger can be used to filter impurities and particulate matter in the microchannel to maintain the normal operation and long-term stability of the heat exchanger.
