Problems solved by technology

[0002] Due to the isotropic heat conduction characteristics of the current heat sinks (or thermal interface materials), the heat sinks have the characteristics of heat transfer and cold transfer at the same time, which cannot be satisfied in some scenarios that only need heat transfer but not cold transfer. Usage requirements
For example, the lithium battery cannot work normally at low temperature, so it is necessary to heat the lithium battery, but the external environment with low temperature will be transmitted to the battery through the radiator or the shell, so that the heating power of the lithium battery needs to be increased, and more A large amount of electricity will heat the battery, which will seriously affect the battery's power, battery life and life

Embodiment

[0022] Such as Figure 1-3 As shown, this embodiment discloses a one-way heat dissipation module, including a radiator 2 and a two-way memory connector 4, the above-mentioned two-way memory connector 4 is arranged close to the heat source 6, and is arranged between the heat source 6 and the radiator 2 Between, the above-mentioned two-way memory connector 4 can memory expansion and memory contraction, when the above-mentioned two-way memory connector 4 memory expands, it connects the heat source 6 and the radiator 2, and when the above-mentioned two-way memory connector 4 memory shrinks, it separates the heat source 6 and the heat dissipation Device 2. In the technical solution of this embodiment, the two-way memory connector 4 has an expansion critical temperature and a contraction critical temperature. When the temperature of the two-way memory connector 4 exceeds the expansion critical temperature, the two-way memory connector 4 memory expands, and the expanded double The h...

Abstract

The invention discloses a unidirectional heat dissipation module which comprises a heat sink and a two-way memory connector. The two-way memory connector is attached to a heat source, is disposed between the heat source and the heat sink, and can memorize and expansion and contraction. The two-way memory connector is connected to the heat source and the heat sink when memorizing expansion, and separates the heat source and the heat sink when memorizing contraction. In the unidirectional heat dissipation module of the present invention, the heat sink is selectively connected to the heat sourcethrough the two-way memory connector. When the heat source heats the two-way memory connector to reach the expansion critical temperature, the two-way memory connector is expanded to connect the heatsink with the heat source so as to dissipate the heat generated by the heat source. When the temperature of the two-way memory connector is lower than the contraction critical temperature, the two-waymemory connector contracts to disconnect the heat sink from the heat source, and thus the heat sink does not dissipate the heat of the heat source, and a heat preservation effect is provided for theheat source. Thus, the unidirectional heat dissipation module achieves unidirectional heat transfer between the heat source and the heat sink.
