Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Specific examples are given below.

[0023] See also Figure 1-Figure 5 The temperature and humidity controller described in the utility model comprises a shell 1, a display control panel 2 is installed on one side of the shell 1, an array of mounting shells 3 are arranged in an array on the side plate of the shell 1, the mounting shells 3 are connected on both sides close to the inside and outside of the shell 1, an active cavity 4 is opened in the mounting shell 3, a moving box 5 is movably arranged in the active cavity 4, and a plurality of shape memory alloy springs 6 are connected to the opposite ends of the active cavity 4 and the moving box 5 in an array, and the shape memory alloy springs 6 have two states, which are used to drive the moving box 5 to extend and retract in the active cavity 4;

[0024] The shape memory effect of the shape memory alloy spring 6 is that when the temperature rises, the shape memory alloy spring 6 is in a stretched state, and when the temperature drops below the set temperature, the shape memory alloy spring 6 is in a contracted state. When working, in order to improve the heat dissipation efficiency of the temperature and humidity controller, first, when the working temperature of the temperature and humidity controller rises to the setting of the shape memory alloy spring 6, the memory shape of the shape memory alloy spring 6 is set to a stretched state at high temperature. When the temperature gradually reaches a specific transformation temperature or temperature range, above this temperature, the shape memory alloy spring 6 will lose its martensite phase, that is, the shape at low temperature, and return to the austenite phase, that is, the memory shape, so that the shape memory alloy spring 6 casting is stretched and lengthened, and a number of shape memory The alloy spring 6 pushes the moving box 5 to move, so that the moving box 5 gradually extends into the shell 1, increasing its area, thereby increasing its heated area and greatly improving the heat dissipation efficiency. On the contrary, when the temperature gradually decreases and reaches below the transformation temperature, the shape memory alloy spring 6 will be transformed into the martensite phase again, that is, the shape at low temperature, that is, the contracted state gradually becomes shorter, and at the same time drives the moving box 5 to move into the active cavity 4, reducing its heated area. Through the cooperation of the above structure, the temperature and humidity controller shell 1 can automatically adjust the heat dissipation capacity according to the change of ambient temperature, so that the temperature and humidity controller can operate stably under a wider range of environmental conditions, thereby improving the service life, reducing the aging and damage of components caused by high temperature, and extending the service life of the temperature and humidity controller.

[0025] Furthermore, a plurality of through holes 7 are arranged in an array on the side panels of the moving box 5. When the moving box 5 is in operation, the plurality of through holes 7 allow air to circulate in the housing 1 to take away the heat inside the housing 1, thereby greatly improving the heat dissipation performance.

[0026] Furthermore, a plurality of heat sinks 8 are fixedly arranged in an array inside the mobile box 5, and the heat sinks 8 are made of copper. When working, the plurality of heat sinks 8 arranged on the mobile box 5 have good thermal conductivity.

When the temperature gradually reaches a specific transformation temperature or temperature range, above this temperature, the shape memory alloy spring 6 will lose its martensite phase, that is, the shape at low temperature, and return to the austenite phase, that is, the memory shape, so that the shape memory alloy spring 6 casting is stretched and lengthened. Several shape memory alloy springs 6 push the moving box 5 to move, so that the moving box 5 gradually extends into the inside of the shell 1, increasing its area, thereby increasing its heated area and greatly improving the heat dissipation efficiency. Several through holes 7 opened on the moving box 5 allow air to circulate in the shell 1, taking away the internal heat, greatly improving the heat dissipation performance. On the contrary, when When the temperature gradually decreases and falls below the transition temperature, the shape memory alloy spring 6 will be transformed back into the martensite phase, that is, the shape at low temperature, that is, the contracted state gradually becomes shorter, and at the same time drives the moving box 5 to move into the active cavity 4, reducing its heated area. Through the cooperation of the above structure, the temperature and humidity controller housing 1 can automatically adjust the heat dissipation capacity according to the change of ambient temperature, so that the temperature and humidity controller can operate stably under a wider range of environmental conditions, thereby improving the service life, reducing the aging and damage of components caused by high temperature, and extending the service life of the temperature and humidity controller; a number of heat sinks 8 are arranged on the moving box 5, which have good thermal conductivity. The addition of the heat sink 8 can effectively transfer heat from the inside of the housing 1 to the external environment.
