Description

technical field [0001] The invention relates to the field of energy saving, in particular to a phase change thermal storage one-way heat transfer device and a manufacturing method thereof. Background technique [0002] With the development of science and technology, people have higher and higher requirements for "heat dissipation". There are three basic ways of heat transfer: conduction, convection and radiation. The main heat dissipation method in daily life and industrial production is natural heat dissipation, which transfers heat through the direct temperature difference between the heat source and the air, so as to achieve the purpose of "heat dissipation". [0003] However, for boiler rooms, cabinets and other spaces that require high heat dissipation, natural heat dissipation methods cannot meet their heat dissipation requirements. For example, the internal equipment of some cabinets generates a lot of heat during use, and ordinary natural heat dissipation methods ca...
