Embodiment 1
[0028] Referring to Figure 2, Figure 2 is a schematic diagram of the first embodiment of the refrigeration device of the present invention. It can be seen from Figure 2 that the device includes a cold end radiator 22 and a cold end phase change unit 23. The cold end phase change unit 23 is assembled in the The cold-end radiator 22 is used for releasing cooling capacity, and the cold-end phase change unit 23 is filled with a phase change material for accumulating cooling capacity.
[0029] The cooling capacity in the electronic device 24 is transmitted to the cold-end phase change unit 23. One side of the cold-end phase change unit 23 is connected to the electronic device 24 (such as a semiconductor chip) through a thermal grease or a thermal pad, and the other side is connected to The base plates of the cold-end radiator 22 are connected, and the cold-end fan 21 distributes the cooling capacity to the cold-end space, so that the cold-end space can be cooled. In order to enable the...
Embodiment 2
[0035] In the embodiment of the refrigeration device of the present invention, the cold-end phase change unit is built into the cold-end radiator. For example, one side of the cold-end phase change unit is connected to the base plate of the cold-end radiator, and the other side is connected to the fin of the cold-end radiator. Connected.
Embodiment 3
[0037] The embodiment of the refrigeration device of the present invention adds a cold-end phase change unit on the side of the fin of the cold-end radiator.
[0038]At the same time, the cold end phase change unit or the hot end phase change unit built-in heat dissipation fins or heat pipes can uniform the temperature of the PCM phase change material, so that its heat storage performance can be fully exerted. The temperature of the PCM material is uniformed by the method of built-in heat dissipation fins, as shown in Fig. 3. At the same time, the upper part of the heat sink filled with PCM material can also have external fins. The method of using built-in heat pipe to homogenize the temperature of the PCM material can be seen in Fig. 4. At the same time, the upper part of the radiator filled with PCM material can also have external fins.
[0039] Heating device embodiment one
[0040] The embodiment of the present invention also provides a heating device. Referring to FIG. 5, FIG...
