Embodiment 1

[0033] In order to improve the heat dissipation efficiency, in this embodiment, a preferred structure of the heat dissipation cavity 103 is disclosed, and grooves 110 are evenly spaced on the side wall of the housing 102 away from the end of the phase change heat storage material 104 .

[0034] By providing the groove structure, the surface area of ​​the heat dissipation cavity can be increased, so that it has better heat dissipation efficiency.

[0035] In this embodiment, another preferred structure for improving heat dissipation efficiency is also disclosed. A diffuser 106 is provided at the end of the heat transfer cavity 103 away from the fan 105 .

[0036] In order to generate noise during operation of the surface diffuser 106 , in this embodiment, a noise reduction device is provided between the diffuser 106 and the housing 102 .

[0037] Preferably, the driving device 109 is a hydraulic cylinder.

Embodiment 2

[0039] A method for automatically detecting deicing, comprising the steps of:

[0040] S1: Detect the external temperature and humidity of the casing 102: use a temperature sensor and a humidity sensor to detect the external temperature and humidity values ​​of the casing 102, and send them to the control circuit, and the control circuit compares the temperature and humidity values;

[0041] S2: Drive the solar thermal collector plate 101 to turn: when the detected temperature reaches 0°C and the humidity reaches the set value in step S1, the control circuit sends an excitation signal to the driving device 109 to push the solar thermal collector plate 101 to turn over to face the direction of light;

[0042] S3: Start the fan 105 : the control circuit sends a drive signal to the fan 105 to blow air to the heat transfer cavity 103 .

Abstract

The invention discloses an automatic deicing device. The automatic deicing device comprises a solar heat collection panel and a heat radiation device arranged below the solar heat collection panel. A light-heat conversion device is arranged between the solar heat collection panel and the heat radiation device. The heat radiation device comprises a shell and a heat transfer cavity formed in the shell. A phase-change heat storage material is arranged between the heat transfer cavity and the shell. A fan connected with the heat transfer cavity is arranged at one end of the shell and connected with a control circuit through a line. A humidity sensor and a temperature sensor are arranged on the outer side of the shell and connected with the control circuit through lines. Conversion of heat energy is achieved through the phase-change heat storage material, and meanwhile regulation of heat collection efficiency is achieved through the solar heat collection panel capable of being regulated in a turnover mode.
