The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0024] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0025] like Figures 1 to 5 As shown, a high-temperature and high-humidity resistant electronic watch includes a heat-conducting housing 1 and a heat-conducting bottom cover 2. An electronic component assembly 5 is disposed within the heat-conducting housing 1. The electronic component assembly 5 includes a battery compartment located at its bottom. A display screen 3 is connected to the top of the electronic component assembly 5. The display screen 3 is sealed to the heat-conducting housing 1. The heat-conducting bottom cover 2 is detachably and sealed to the heat-conducting housing 1. An elastic protruding ring 12 is fixed to the inner side of the heat-conducting bottom cover 2. An inner heat-conducting plate 6 is disposed at the bottom of the electronic component assembly 5. The heat-conducting bottom cover 2, the elastic protruding ring 12, and the inner heat-conducting plate 6 together form a receiving space. A phase change plate 7 is disposed within the receiving space. The phase change plate 7 is sealed and leak-proof under the action of the elastic protruding ring 12. The phase change temperature of the phase change plate 7 is set at 48℃-52℃.
[0026] The heat-conducting shell 1 and the heat-conducting bottom cover 2 are made of the same material, both using high thermal conductivity aluminum alloy, and are anodized on the surface to form a dense oxide film, making them resistant to sweat corrosion.
[0027] The inner heat-conducting plate 6 is made of copper, which has excellent thermal conductivity and is inexpensive.
[0028] The top of the heat-conducting housing 1 has a receiving groove, and a plastic sealing ring 14 is fixedly installed on the side wall of the receiving groove. A limiting part 13 is formed at the inner edge of the display screen 3. The limiting part 13 is tightly abutted against the bottom of the sealing ring 14, and the side wall of the display screen 3 is tightly abutted against the side wall of the sealing ring 14, so as to elastically seal the display screen 3 and the receiving groove and ensure the top waterproof performance.
[0029] The bottom of the heat-conducting bottom cover 2 is provided with a bolt 8, a sealing washer 16 is arranged between the connecting position of the heat-conducting bottom cover 2 and the heat-conducting shell 1, and the bolt 8 penetrates the sealing washer 16 to threadedly connect the heat-conducting shell 1 and the heat-conducting bottom cover 2, so that the heat-conducting bottom cover 2 and the heat-conducting shell 1 are tightly sealed against the sealing washer 16 at both ends, respectively, to ensure the waterproof performance of the bottom.
[0030] The bottom of the heat-conducting shell 1 is provided with guide grooves 9 in the vertical direction on both sides, the inner heat-conducting plate 6 is formed with guide portions 10 matched with the guide grooves 9 on both sides, and the inner heat-conducting plate 6 is provided with pull grooves 11 near the guide portions 10. When the inner heat-conducting plate 6 is installed, the guide portions 10 are aligned with the guide grooves 9 and buckled to be accurately installed. When the inner heat-conducting plate 6 is removed, the outer J-shaped hook is inserted into the pull grooves 11 to pull out the inner heat-conducting plate 6 outward.

[0032] The implementation principle of the embodiment of the present application is that during use of the product, the heat on the electronic component assembly 5 is first conducted to the inner heat-conducting plate 6 at the bottom, then part of the heat is transmitted to the heat-conducting shell 1 to conduct the internal heat outward to achieve passive heat dissipation, and the other part is transmitted to the phase change sheet 7 position. The phase change sheet 7 absorbs and stores the peak heat through solid-liquid phase change, inhibits temperature rise in a high-temperature environment, actively dissipates heat for the electronic component assembly 5, and then the heat on the phase change sheet 7 is conducted outward along the heat-conducting bottom cover 2 to the human wrist position to assist in heat dissipation, so as to avoid overheating failure of the internal electronic components. When the phase change sheet 7 is used for a long time and the performance is poor or the battery in the electronic component assembly 5 is insufficient, the bolt 8 at the bottom is loosened, and the heat-conducting bottom cover 2, the phase change sheet 7 and the inner heat-conducting plate 6 are sequentially separated and taken out, so as to facilitate replacement of the phase change sheet 7 and the battery.
