[0003] The existing high-temperature VOC cabin can reach 250°C or even higher, and uses jacket temperature control, which can only cool down by ventilation. When the temperature in the cabin reaches or exceeds the boiling point of water, the water will evaporate rapidly and lose the temperature control effect, and it is not possible to use water as a temperature control medium. Even if the boiling point of water is increased by pressurization or other means to keep it in a liquid state at a higher temperature, on the one hand, the cost is high, and on the other hand, the heat conduction performance of water will decrease significantly at high temperature, resulting in low heat conduction and temperature control efficiency. Therefore, in the prior art, the cooling of the high-temperature VOC cabin is carried out by a large air compressor for ventilation, but the air volume produced by the large air compressor per unit time is small, the air pressure is high, the noise is loud, and the cost of the whole machine and accessories is high.

[0015] DETAILED DESCRIPTION
[0019] The preferred embodiments of the utility model will be described in detail below with reference to the drawings, and the utility model will be further described.
[0020] Firstly, the high-temperature VOC cabin cooling device according to the embodiments of the utility model will be described in combination with Figure 1 The high-temperature VOC cabin cooling device according to the embodiments of the utility model is widely applied in environmental protection testing and other scenes. In the present embodiment, the related test of detecting VOC at high temperature is taken as an example for illustration.
[0021] As shown in Figure 1 The high-temperature VOC cabin cooling device according to the embodiments of the utility model is used for cooling the high-temperature VOC cabin. In the prior art, high temperature generally refers to a test temperature higher than 250 degrees Celsius.
[0022] Specifically, as shown in Figure 1 The high-temperature VOC cabin cooling device comprises a convection assembly 2 and a conduction assembly 3. The convection assembly 2 is arranged outside the test cabin body 1 and is provided with an air outlet. The side of the test cabin body 1 opposite to the convection assembly 2 is provided with an opening. The air outlet can output flowing gas and the flowing gas enters the test cabin body 1 from the opening. Since the one-step cooling in the prior art is changed into a multi-step cooling process, when the temperature difference between the inside and outside of the test cabin body 1 is very large, the fluid flow can also be used for rapid cooling, and it is not necessary to use an air compressor for pressurization. Moreover, the air volume of the fan without pressurization is larger, and the controllability is stronger. In actual operation, energy is saved, and noise is low. The conduction assembly 3 is arranged inside the test cabin body 1. The conduction assembly 3 is connected with the sensor and is controlled by the controller to a preset temperature. The conduction assembly 3 and the inside of the test cabin body 1 can generate heat conduction. The jacket traditionally arranged outside the test cabin body 1 is changed into the conduction assembly 3 arranged inside the test cabin body 1. The conduction assembly 3 directly utilizes the flowing refrigerant to perform heat conduction with the inside of the test cabin body 1, and is more efficient than the jacket.
[0023] Preferably, the convection assembly 2 comprises a fan. The convection is realized by the fan. The high-temperature air in the cabin can be quickly extracted in circulation, and is replaced by the relatively low-temperature cold air from the outside, so that rapid cooling is realized. The cost and maintenance cost of the fan are significantly reduced compared with the large air compressor. In the stage where the temperature is reduced to above 110 degrees, the cooling efficiency of the fan is almost not inferior to that of the large air compressor, but the energy consumption is smaller and the noise is significantly reduced.
[0024] Preferably, as shown in Figure 1As shown, a filter box 4 is provided between the air outlet of the fan and the opening, and the fluid from the air outlet passes through the filter box 4 before entering the test cabin 1. The filter box 4 can filter out dust, particles and other impurities in the air entering the test cabin 1, keeping the cabin environment clean. This is particularly important for VOC cabins that require high-precision test conditions, as it can avoid the impact of external pollution on test results.
[0025] Preferably, the fan includes a frequency converter that adjusts the air volume and flow rate of the fan. The frequency converter can adjust the air volume and flow rate of the fan, making the cooling process more flexible and controllable. According to different cooling needs, the operating state of the fan can be adjusted to achieve energy saving and consumption reduction.
[0026] Preferably, the convection assembly 2 also includes a liquid evaporator (not shown in the figure), and the fluid entering the test cabin 1 through the opening includes both gas and evaporated liquid. The addition of the liquid evaporator allows the fluid entering the test cabin 1 to contain not only gas but also evaporated liquid. This can further improve the cooling efficiency, as the evaporated liquid can absorb a large amount of heat, thereby achieving faster cooling.
[0027] Preferably, the conduction assembly 3 is hollow inside and can flow with refrigerant. The hollow interior of the conduction assembly 3 and the flow of refrigerant can fully utilize the heat conduction properties of the refrigerant to quickly remove heat from the cabin. When the temperature in the test cabin gradually approaches room temperature, the cooling effect of the convection assembly 2 is poor, and the conduction assembly 3 is turned on and the temperature of the refrigerant is controlled to achieve better cooling effect.
[0028] Preferably, the conduction assembly 3 is a number of groups of coils, and each group of coils can be controlled by a controller. Each group of coils being controlled by a controller separately allows for precise cooling of different areas within the cabin. This design improves the flexibility and adaptability of the cooling system, better meeting complex and variable test requirements.
[0029] Preferably, the conduction assembly 3 is a finned heat sink, a plate-type heat sink or a spiral heat sink. These types of heat sinks have high heat dissipation efficiency and can quickly dissipate heat from the cabin to the outside. The finned heat sink increases the heat dissipation area to improve heat dissipation efficiency; the plate-type heat sink has a compact structure and uniform heat dissipation; the spiral heat sink can enhance heat dissipation by utilizing the spiral motion of the fluid. The choice of these types of heat sinks can be determined according to specific test conditions and cooling requirements to achieve the best cooling effect. Although these heat sinks do not have as good a cooling effect as controlling the temperature of the refrigerant to quickly dissipate heat, and are not as adaptable as controlling the refrigerant, they can be used for cooling in scenarios where efficiency is not required or at the end of an experiment, achieving noiseless and energy-saving cooling.
[0030] After a round of testing is completed in test chamber 1, when cooling is required, the first stage is to activate convection component 2. High-speed fluid enters the test chamber through the opening and forms a circulation within the chamber to remove heat. The air volume and flow rate can be adjusted as needed. When the temperature reaches the critical point, the boundary efficiency of convection component 2 decreases significantly. The second stage is then activated to use conduction cooling to further remove heat from the test chamber. One or more sets of coils can be activated according to efficiency requirements to achieve the desired effect while saving energy and reducing emissions as much as possible.
[0031] Above, refer to Figure 1 This invention describes a high-temperature VOC chamber cooling device according to an embodiment of the present invention. Through the synergistic effect of the conduction component 3 and the convection component 2, the cooling of the high-temperature VOC chamber can be achieved more efficiently. This solution combines cooling methods for both high-temperature and low-temperature VOC chambers and specifically adjusts the layout of the conduction component 3. The conduction component 3 directly utilizes the refrigerant for heat conduction with the interior of the test chamber 1, reducing unnecessary energy loss. The first stage uses convection, and the second stage uses conduction. The switching time and temperature critical point between the two can be adjusted according to experimental requirements, allowing for more intelligent adaptation to different test objects. Compared to traditional large air compressor cooling methods, this solution can further improve cooling efficiency through temperature control and optimized heat conduction component 3 area and refrigerant application, thereby reducing long-term operating costs.

[0033] The high-temperature VOC chamber of the second embodiment of this utility model can efficiently cool down and save energy, while significantly reducing the noise level during equipment operation, providing a quieter working environment. This is not only beneficial to the physical and mental health of operators, but also avoids noise interference that would otherwise make the experimental process more efficient and comfortable when precise monitoring and recording of experimental data are required.
