[0021] Furthermore, a heat exchange chamber 107 is provided at the upper end of the first air inlet 1061, a partition 1073 is provided between the heat exchange chamber 107 and the first air inlet 1061, a mounting groove 1074 is provided on the partition 1073, the semiconductor refrigeration plate 201 is installed in the mounting groove 1074, the thickness of the partition 1073 is equal to the thickness of the semiconductor refrigeration plate 201, a heat exchanger 205 is provided on the upper end surface and the lower end surface of the semiconductor refrigeration plate 201, a second motor 204 is provided in the test box 1, a rotating shaft 2052 cooperating with the second motor 204 is provided on the side of the heat exchanger 205, the first temperature sensor 202 is installed on the upper end surface of the test box 1, and the second temperature sensor 203 is installed on the bottom upper end surface of the test chamber 106.

[0022] The semiconductor cooling chip 201, also called a thermoelectric cooling chip, is a heat pump. When direct current passes through a thermocouple formed by two different semiconductor materials in series, heat can be absorbed and released at both ends of the thermocouple respectively. On one side of the cooling chip, the current makes the contact area cold; and on the other side, the contact area becomes hot. Therefore, one side becomes the cold end and the other side becomes the hot end. The current room temperature is detected by the first temperature sensor 202, and the real-time temperature in the test chamber 106 is detected by the second temperature sensor 203. When the controller 103 inputs the experimental temperature, the controller 103 compares the input temperature with the temperature of the first temperature sensor 202. If it is higher than the room temperature, the second motor 204 drives the semiconductor cooling chip 201 to rotate to the hot end facing downward. If it is lower than the room temperature, the cooling chip is driven to rotate to the cold end facing downward. The first fan 206 draws air to evenly draw the hot air flow or cold air flow into the test chamber 106, so that the computer can be tested in a relatively stable temperature environment.

[0023] Furthermore, a second air inlet 1071 is provided on the top of the heat exchange chamber 107, a second air outlet 1072 is provided on the side of the heat exchange chamber 107, a second fan 404 is provided in the heat exchange chamber 107, the heat exchanger 205 is a semi-cylindrical structure, and heat exchange wings 2051 are provided on the surface of the heat exchanger 205.

[0024] Air is blown by the second fan 404 to dissipate heat for the semiconductor refrigeration plate 201. If the hot end temperature is lowered by active heat dissipation, the cold end temperature will also drop accordingly, thereby reaching a lower temperature. Similarly, if the air flow rate on the cold end surface is accelerated to increase the cold end temperature, the hot end temperature will rise, thereby making the hot end reach a higher temperature. By increasing the heat dissipation or heat absorption rate of the upper end surface of the semiconductor refrigeration plate 201, the cooling or heating efficiency of the lower end surface of the semiconductor refrigeration plate 201 is improved. By increasing the heat dissipation area of ​​the heat exchanger 205 through the heat exchange fins 2051, the cooling or heating efficiency is further improved.

[0025] Furthermore, the belt-type dust curtain 303 is an annular nylon net, the driving roller 301 is located at the upper end of the partition 1073, the driven roller 302 is located at the bottom of the first air inlet 1061, the belt-type dust curtain 303 is sleeved on the driving roller 301 and the driven roller 302 and is transmitted by friction, the output shaft of the first motor 204 is keyed to the driving roller 301, and rubber strips 304 are provided on the edges of the driving roller 301, the driven roller 302 and the belt-type dust curtain 303.

[0026] The driven roller 302 is driven to rotate by the first motor 204, thereby driving the belt dust curtain 303 to rotate, so that the dust removal mechanism 4 removes dust from various positions of the belt dust curtain 303. The rubber strip 304 is arranged on the belt dust curtain 303 and the driving roller 301 and the driven roller 302, which can effectively enhance the structural strength of the edge of the belt dust curtain 303, and enhance the friction between the belt dust curtain 303 and the driving roller 301, thereby enhancing the transmission effect.

[0027] Furthermore, a first synchronous wheel 4011 is provided on the brush roller 401, a second synchronous wheel 3011 is provided on the driving roller 301, a synchronous belt 4012 for transmission is provided on the first synchronous wheel and the second synchronous wheel 3011, a first gear 3012 is provided on the driving roller 301, and a second gear 4021 is provided on the sticking roller 402. The driving roller 301 and the sticking roller 402 are driven by meshing of the first gear 3012 and the second gear 4021.

[0028] When the first motor 204 drives the driving roller 301 to rotate, the brush roller 401 is driven to rotate in the same direction through the synchronous belt 4012 and the first synchronous wheel 4011 and the second synchronous wheel 3011. At the same time, the sticky roller 402 is driven to rotate in the opposite direction through the first gear 3012 and the second gear 4021, so that the brush roller 401 brushes the dust on the surface of the belt-type dust curtain 303 outwards, and the swept dust is blown to the second air outlet 1072 by the second fan 404, and the small amount of dust remaining on the surface of the belt-type dust curtain 303 is removed by the sticky roller 402.

[0029] Furthermore, the surface of the brush roller 401 is provided with nylon bristles, the sticky roller 402 includes a key shaft 4022 and a sleeve 4023, the sleeve 4023 is sleeved on the key shaft 4022 and slidably connected thereto, the surface of the sleeve 4023 is provided with a sticky silicone layer, and the front end face of the test box 1 is provided with an inspection port 104 corresponding to the sticky roller 402.

[0030] The surface of the belt-type dust curtain 303 is swept by a nylon brush, and the sticky silicone layer on the surface of the sticky roller 402 removes the remaining small amount of dust. By providing an inspection port 104 on the front end face of the test box 1, the key shaft 4022 and the sleeve 4023 structure that are slidably connected facilitate the replacement of a new sleeve 4023 or the cleaning and repair of an old sleeve 4023, thereby maintaining its stickiness.

[0031] Furthermore, a dustproof net is provided in the second air inlet 1071 , the dust collecting box 403 is interference installed at the second air outlet 1072 , and a dust removing cloth 4031 is provided on the side of the dust collecting box 403 .

[0032] The dust blown away by the second fan 404 enters the dust box 403 and is trapped by the dust removal cloth 4031 at the bottom of the dust box 403. The interference-connected dust box 403 is easy to disassemble and clean.

[0033] Furthermore, a slider 1081 is disposed at the bottom of the support seat 108 , a slide rail 1063 cooperating with the slider 1081 is disposed in the test chamber 106 , and a magnet sheet 1082 is disposed on the upper end surface of the support seat 108 .

[0034] The notebook is supported by the support base 108 so that the bottom of the notebook is suspended in the air. The slidingly connected support base 108 is convenient for adjusting the spacing to accommodate notebooks of different sizes. The magnet sheet 1082 can be adsorbed on the bottom of the notebook to fix it and prevent it from moving and shaking.

[0035] Furthermore, the sealing cover 101 is made of transparent PC material, and a thermal imager 102 is disposed on the inner end surface of the sealing cover 101 .

[0036] The sealing cover 101 made of transparent material is convenient for viewing the real-time temperature displayed by the monitoring software on the notebook display screen, and the heat distribution of the body is convenient for observing through the thermal imager 102, which is convenient for later optimization and improvement.

[0037] See also Figure 1-Figure 9 , a computer heat dissipation performance testing method, comprising the following steps: Step 1, open the notebook, run the baking machine temperature measurement software installed in the notebook, then place the notebook on the support base 108, and ensure that its bottom is suspended to facilitate air circulation, close the sealing cover 101, and start the preparation work before the test; Step 2: Set the temperature required for the test through the controller 103. The controller 103 automatically adjusts the working state of the semiconductor refrigeration sheet 201 to achieve the set temperature condition. The first temperature sensor 202 detects the external ambient temperature, and the second temperature sensor 203 detects the temperature inside the test chamber 106. The controller 103 adjusts the working state of the semiconductor refrigeration sheet 201 based on the target temperature set by the user to maintain a constant temperature in the test chamber 106. If the target temperature is higher than the ambient temperature, the controller 103 will use the second motor 204 to turn the hot end of the refrigeration sheet downward, otherwise, the cold end will be turned downward; Step 3: Air enters through the first air inlet 1061 and is filtered by the belt-type dust curtain 303 to reduce dust from entering the test chamber 106. The belt-type dust curtain 303 is driven by the first motor 204 and moves through the friction between the driving roller 301 and the driven roller 302 to filter the air entering the test chamber 106. Step 4, except that during the test, the dust removal mechanism 4 continues to work, and the dust curtain is kept clean by using the brush roller 401 and the sticky roller 402 in combination. The brush roller 401 and the sticky roller 402 are used in combination. The former removes dust on the dust curtain through nylon bristles, and the latter further cleans through the sticky silicone layer. The first motor 204 drives the rotation of the brush roller 401 and the sticky roller 402 at the same time to achieve an efficient dust removal process; Step 5: Observe the real-time temperature of each hardware in the baking software through the sealing cover 101 , and check the temperature distribution of each position of the laptop computer through the thermal imager 102 .

[0038] During step 2 and step 3, in order to improve the efficiency of the refrigeration plate, the heat exchange chamber 107 is provided with a second fan 404 and a heat exchanger 205, which helps the hot end to dissipate heat or the cold end to absorb heat by increasing the air circulation speed, thereby affecting the temperature change at the other end. At the same time, the second fan 404 uses suction to absorb the dust brushed by the brush roller 401, and filters it through the dust removal cloth 4031, and the dust is trapped in the dust collecting box 403, thereby greatly reducing the replacement frequency of the sticky roller 402.
