Description

Technical Field

[0001] This utility model relates to the field of air treatment technology, specifically to a coupling system of HVAC and carbon capture devices. Background Technology

[0002] In related technologies, HVAC (Heating, Ventilation, and Air Conditioning) is an air conditioning system that provides heating, ventilation, and air conditioning. It is used in various locations, such as buildings and vehicles, to effectively regulate the indoor environment and improve comfort. However, the carbon emissions from HVAC systems can further increase the concentration of carbon dioxide in the atmosphere.

[0003] Direct air carbon capture (DAC) devices are used to directly capture carbon dioxide from the atmosphere, thereby reducing the carbon dioxide content in the atmosphere. Placing DAC devices outside a site is beneficial for reducing the carbon dioxide content outside the site, but the energy consumption of installing a standalone DAC device is relatively high, and the heat dissipated from the HVAC radiators to the outside of the site can affect the adsorption process of the DAC device. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a coupled system of HVAC and carbon capture devices, capable of reducing carbon dioxide content by utilizing waste heat generated during indoor environment regulation.

[0005] A coupling system for a heating, ventilation, air conditioning system and a carbon capture device according to a first aspect embodiment of the present invention, used for carbon capture and temperature regulation of an indoor environment, includes: A heating, ventilation, and air conditioning system includes a housing and a radiator. The housing has a heat dissipation channel, which has a first heat dissipation section and a second heat dissipation section that are interconnected and isolated from each other. The first heat dissipation section is connected to the outside. At least a portion of the radiator is disposed within the second heat dissipation section and is used to introduce heat from the indoor environment into the second heat dissipation section. A direct air carbon capture device includes a collection component, a heating component, and a carbon capture unit, wherein the carbon capture unit is disposed within the first heat dissipation section; the carbon capture unit has an adsorption state and a desorption regeneration state that cycle sequentially. The direct air carbon capture device is configured such that when the carbon capture unit is in the adsorption state, it adsorbs carbon dioxide, and the first heat dissipation section and the second heat dissipation section are isolated from each other; when the carbon capture unit is in the desorption and regeneration state, the first heat dissipation section and the second heat dissipation section are connected to each other, the heating component heats the carbon capture unit, and the collecting component collects the carbon dioxide desorbed by the carbon capture unit.

[0006] The coupling system of HVAC and carbon capture device according to the present invention has at least the following beneficial effects: In the adsorption state, the carbon capture unit can adsorb carbon dioxide entering the carbon capture unit from the first heat dissipation section, thereby reducing the carbon dioxide concentration in the first heat dissipation section. Since the first heat dissipation section and the second heat dissipation section are isolated from each other, the heat dissipated by the radiator to the second heat dissipation section is difficult to flow to the first heat dissipation section through the air. The temperature of the first heat dissipation section is lower, and the carbon capture unit can adsorb carbon dioxide better. In the desorption and regeneration state, the first heat dissipation section and the second heat dissipation section are interconnected. The gas in the second heat dissipation section can flow into the first heat dissipation section. The aforementioned air flow process can drive the heat around the radiator to flow to the first heat dissipation section and heat the carbon capture unit. This is beneficial for the carbon capture unit in the desorption and regeneration state to desorb carbon dioxide, reduce the power consumption of the heating component in heating the carbon capture unit, and also allow the air with a higher carbon dioxide concentration in the second heat dissipation section to replenish the first heat dissipation section, increase the carbon dioxide concentration in the first heat dissipation section, and increase the adsorption rate when the carbon capture unit re-enters the adsorption state. At the same time, the air with a lower carbon dioxide concentration in the first heat dissipation section is sent to the outside, reducing the carbon dioxide concentration around the HVAC system and lowering the carbon dioxide concentration in the atmosphere.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0024] Please refer to Figures 1 to 3 As shown, this utility model proposes a coupling system for HVAC and a carbon capture device. The coupling system of this utility model is used for carbon capture and temperature regulation of the indoor environment, and includes an HVAC system 100 and a direct air carbon capture device 200.

[0025] The HVAC 100 of this utility model includes a housing 110 and a radiator 120. The housing 110 has a heat dissipation channel 111, which has a first heat dissipation section 1111 and a second heat dissipation section 1112 that are interconnected and isolated from each other. The first heat dissipation section 1111 is connected to the outside. At least a portion of the radiator 120 is disposed in the second heat dissipation section 1112 and is used to introduce heat from the indoor environment into the second heat dissipation section 1112.

[0026] The HVAC 100 of this invention is an air conditioner with heating, ventilation, and air conditioning functions. Those skilled in the art can easily install the HVAC 100 in various locations, such as various buildings 10 and various vehicles. The radiator 120 of this invention can introduce heat from the indoor environment into the second heat dissipation section 1112, thereby achieving temperature control of the indoor environment.

[0027] Without departing from the inventive concept of this utility model, those skilled in the art can design the structure of the heat sink 120 themselves. Please refer to... Figure 1 As shown, where Figure 1 The illustration shows an example of a heating, ventilation, and air conditioning (HVAC) system 100 installed in a building 10. In some embodiments, the radiator 120 includes a heat-conducting pipe 121 and a heat-dissipating pipe 122. One end of the heat-conducting pipe 121 is connected to the heat-dissipating pipe 122, and the other end is located in the indoor environment to guide heat from the indoor environment to the heat-dissipating pipe 122. The heat-dissipating pipe 122 is located in a second heat dissipation section 1112 and is used to introduce the heat guided by the heat-conducting pipe 121 into the second heat dissipation section 1112. This configuration allows heat to be guided into the second heat dissipation section 1112 for heat dissipation via the heat-conducting pipe 121.

[0028] The direct air carbon capture device 200 of this utility model includes a collection component 210, a heating component 220 and a carbon capture unit 230, the carbon capture unit 230 is disposed in the first heat dissipation section 1111; the carbon capture unit 230 has an adsorption state and a desorption regeneration state that are carried out in sequence.

[0029] The direct air carbon capture device 200 of this invention utilizes the adsorption structure 231 in the existing carbon capture unit 230 to capture carbon dioxide. In the prior art, the adsorption structure can adsorb carbon dioxide in the atmosphere at room temperature, and after being heated to a certain temperature, the adsorbed carbon dioxide will detach from itself. However, placing the direct air carbon capture device directly outside the site will cause the heat discharged from the HVAC system to affect the adsorption process of the adsorption structure when it is extended above room temperature, thus reducing the adsorption efficiency of the adsorption structure. On the other hand, the energy consumption of the direct air carbon capture device is also relatively high.

[0030] In view of this, the direct air carbon capture device 200 of this utility model is configured such that when the carbon capture unit 230 is in the adsorption state, it adsorbs carbon dioxide, and the first heat dissipation section 1111 and the second heat dissipation section 1112 are isolated from each other. When the carbon capture unit 230 is in the desorption and regeneration state, the first heat dissipation section 1111 and the second heat dissipation section 1112 are connected to each other, the heating component 220 heats the carbon capture unit 230, and the collecting component 210 collects the carbon dioxide desorbed by the carbon capture unit 230.

[0031] Since the heat from the radiator 120 is directly dissipated to the second heat dissipation section 1112, and when the carbon capture unit 230 is in the adsorption state, the first heat dissipation section 1111 and the second heat dissipation section 1112 are isolated from each other. Therefore, the heat dissipated from the radiator 120 to the second heat dissipation section 1112 is difficult to reach the first heat dissipation section 1111 through air flow. The temperature of the first heat dissipation section 1111 is lower, so the carbon capture unit 230 in the adsorption state can better adsorb carbon dioxide and reduce the concentration of carbon dioxide in the first heat dissipation section 1111.

[0032] In the desorption-regeneration state, the first heat dissipation section 1111 and the second heat dissipation section 1112 are interconnected. Gas in the second heat dissipation section 1112 can flow into the first heat dissipation section 1111. This airflow process can drive the heat around the radiator 120 to flow to the first heat dissipation section 1111 and heat the carbon capture unit 230. This is beneficial for the carbon capture unit 230 in the desorption-regeneration state to desorb carbon dioxide, reducing the power consumption of the heating component 220 in heating the carbon capture unit 230. It can also allow the air with a higher carbon dioxide concentration in the second heat dissipation section 1112 to replenish the first heat dissipation section 1111, increasing the carbon dioxide concentration in the first heat dissipation section 1111 and increasing the adsorption rate when the carbon capture unit 230 re-enters the adsorption state. Since the first heat dissipation section 1111 is connected to the outside, the air flowing from the second heat dissipation section 1112 to the first heat dissipation section 1111 can also simultaneously send the air with a lower carbon dioxide concentration in the first heat dissipation section 1111 to the outside, thereby reducing the carbon dioxide concentration around the HVAC 100 and lowering the atmospheric carbon dioxide concentration.

[0033] Without departing from the inventive concept of this utility model, those skilled in the art can adjust the structure of the collection component 210 according to the required installation location of the coupling system of the HVAC and carbon capture device of this utility model.

[0034] Please refer to Figure 3As shown, in some embodiments, the coupling system of HVAC and carbon capture device is installed in various vehicles such as ships, high-speed trains, and cars, or in various commercial buildings such as shopping malls and office buildings. The collection component 210 includes a vacuum pump 211 and a gas storage tank 212, with the vacuum pump 211 connected to the gas storage tank 212. The collection component 210 is configured such that the vacuum pump 211 is connected to the interior of the carbon capture unit 230 in an adsorption state, and draws the carbon dioxide inside the carbon capture unit 230 into the gas storage tank 212. Through the above scheme, the vacuum pump 211 can draw the carbon dioxide inside the carbon capture unit 230 into the gas storage tank 212 for storage, facilitating the transfer of the collected carbon dioxide.

[0035] In other embodiments, the coupling system of HVAC and carbon capture device is located within the plant area, and the collection component 210 includes a collection pipeline. The collection component 210 is configured such that the collection pipeline is connected to the interior of the carbon capture unit 230 in the adsorption state, and can transport the carbon dioxide inside the carbon capture unit 230 to the ground or to the raw material warehouse. Through the above solutions, the collection component 210 can directly bury carbon dioxide underground for storage, or directly transport carbon dioxide to the raw material warehouse, facilitating the direct use of carbon dioxide for production within the plant area.

[0036] Without departing from the inventive concept of this utility model, those skilled in the art can adjust the configuration of the heating component 220. In some embodiments, please refer to... Figure 2 As shown, the heating component 220 surrounds the carbon capture unit 230 and contains a resistance wire. When the resistance wire is energized, it heats the carbon capture unit 230. Those skilled in the art can also use a heating component 220 commonly used in the prior art to heat the carbon capture unit 230.

[0037] It should be noted that this invention does not limit the position of the collecting component 210. In some embodiments, the collecting component 210 is housed within the heat dissipation channel 111. For other embodiments, please refer to... Figures 1 to 3 As shown, the portion of the collection component 210 used to connect the carbon capture unit 230 is housed within the heat dissipation channel 111, while the remaining portion is disposed on the outside of the housing 110. This arrangement helps to reduce the size of the housing 110, thereby reducing the manufacturing cost of the housing 110.

[0038] Those skilled in the art can further adjust the timing of the heating component 220's heating of the carbon capture unit 230. For example, in some embodiments, the heating component 220 is configured to heat the carbon capture unit 230 after a preset time of interconnection between the first heat dissipation section 1111 and the second heat dissipation section 1112. The interconnected first heat dissipation section 1111 and the second heat dissipation section 1112 allow hot air from the second heat dissipation section 1112 to enter the first heat dissipation section 1111, thereby heating the carbon capture unit 230. Heating the carbon capture unit 230 by the heating component 220 after a preset time of interconnection between the first heat dissipation section 1111 and the second heat dissipation section 1112 fully utilizes the heat dissipated from the radiator 120 into the second heat dissipation section 1112 to heat the carbon capture unit 230, thereby reducing the energy consumption of the heating component 220 during the heating process and reducing the energy consumption of the coupled system of HVAC and the carbon capture device.

[0039] Please refer to Figure 1 As shown, in some embodiments, the second heat dissipation section 1112 is connected to the outside. Through the above scheme, the air in the second heat dissipation section 1112 can flow directly to the outside. When the carbon capture unit 230 is in the adsorption state, the first heat dissipation section 1111 and the second heat dissipation section 1112 are isolated from each other, and the hot air in the second heat dissipation section 1112 can flow directly to the outside, which is beneficial to the heat dissipation of the radiator 120.

[0040] In addition to the connection between the second heat dissipation section 1112 and the outside environment, in some embodiments, the coupling system of the HVAC and carbon capture device further includes a first blower assembly 300. The first blower assembly 300 is disposed in the first heat dissipation section 1111 and is configured to continuously blow air from the second heat dissipation section 1112 into the first heat dissipation section 1111 for a preset time when the carbon capture unit 230 switches to the desorption and regeneration state. When the carbon capture unit 230 switches to the desorption and regeneration state, the first heat dissipation section 1111 and the second heat dissipation section 1112 are interconnected. The hot air in the second heat dissipation section 1112 driven by the first blower assembly 300 can quickly flow into the first heat dissipation section 1111, thereby rapidly heating the carbon capture unit 230 and causing the air with a lower carbon dioxide concentration in the first heat dissipation section 1111 to be rapidly discharged to the outside environment driven by the hot air in the second heat dissipation section 1112.

[0041] In addition to the connection between the second heat dissipation section 1112 and the outside environment, in some embodiments, the coupling system of the HVAC and carbon capture device further includes a second blower assembly 400. The second blower assembly 400 is disposed in the second heat dissipation section 1112 and is configured to continuously blow air from the second heat dissipation section 1112 into the first heat dissipation section 1111 for a preset time when the carbon capture unit 230 switches to the desorption and regeneration state. When the carbon capture unit 230 switches to the desorption and regeneration state, the first heat dissipation section 1111 and the second heat dissipation section 1112 are interconnected. The hot air in the second heat dissipation section 1112 driven by the second blower assembly 400 can quickly flow into the first heat dissipation section 1111, thereby rapidly heating the carbon capture unit 230 and causing the air with a lower carbon dioxide concentration in the first heat dissipation section 1111 to be rapidly discharged to the outside environment driven by the hot air in the second heat dissipation section 1112.

[0042] Based on the above solution, those skilled in the art also simultaneously configure a first blower assembly 300 and a second blower assembly 400. When the carbon capture unit 230 switches to the desorption and regeneration state, the first blower assembly 300 and the second blower assembly 400 together continuously blow air from the second heat dissipation section 1112 into the first heat dissipation section 1111 for a preset time. This solution allows the hot air in the second heat dissipation section 1112 to flow into the first heat dissipation section 1111 more quickly, accelerating the heating of the carbon capture unit by the hot air, and allowing the air with a lower carbon dioxide concentration in the first heat dissipation section 1111 to be discharged to the outside more rapidly by the hot air from the second heat dissipation section 1112.

[0043] Please refer to Figures 4 to 6 As shown, in some embodiments, the heating and air conditioning system includes a ventilation component 500, which is used to extract indoor air to the outside. Since there is more human activity indoors, and the environment is enclosed, the carbon dioxide concentration indoors is higher than that outdoors. Therefore, the ventilation component 500 helps to reduce the carbon dioxide concentration indoors. Without departing from the inventive concept of this utility model, those skilled in the art can also provide an air intake component to introduce outside air into the room 11, thereby cooperating with the ventilation component 500 to achieve indoor and outdoor air circulation.

[0044] Based on the installation of ventilation component 500, please refer to the following further details. Figure 4As shown, in some embodiments, the housing 110 is provided with an air outlet 112 communicating with the second heat dissipation section 1112; the ventilation assembly 500 is configured to extract indoor air and deliver it to the second heat dissipation section 1112 through the air outlet 112 during the desorption and regeneration state. Through this scheme, since the first heat dissipation section 1111 and the second heat dissipation section 1112 are connected, the gas in the second heat dissipation section 1112 can flow to the first heat dissipation section 1111. Therefore, air with a higher carbon dioxide concentration in the indoor environment can also enter the first heat dissipation section 1111, increasing the carbon dioxide concentration within the first heat dissipation section 1111. This facilitates contact with air of a higher carbon dioxide concentration when the carbon capture unit 230 re-enters the adsorption state, thereby improving the efficiency of carbon dioxide adsorption when the carbon capture unit 230 re-enters the adsorption state.

[0045] Based on the above solution, this utility model does not restrict whether the second heat dissipation section 1112 is connected to the outside world.

[0046] Please refer to Figure 4 As shown, in some embodiments, the second heat dissipation section 1112 is connected to the outside. Through the above scheme, the air inside the second heat dissipation section 1112 can flow directly to the outside. When the carbon capture unit 230 is in the adsorption state, the first heat dissipation section 1111 and the second heat dissipation section 1112 are isolated from each other, and the hot air inside the second heat dissipation section 1112 can flow directly to the outside, which is beneficial for the heat dissipation of the radiator 120. Without departing from the inventive concept of this utility model, a second blower assembly 400 can also be provided inside the second heat dissipation section 1112. The second blower assembly 400 is configured to continuously extract the air from the second heat dissipation section 1112 to the outside for a preset time when the carbon capture unit 230 switches to the adsorption state. The above scheme enables the hot air dispersed in the second heat dissipation section 1112 to be quickly extracted to the outside, which is beneficial for improving the heat dissipation efficiency of the radiator 120.

[0047] Furthermore, in some embodiments, the coupling system of the HVAC and carbon capture device further includes a first blower assembly 300, which is disposed in the first heat dissipation section 1111. The first blower assembly 300 is configured to continuously blow air from the second heat dissipation section 1112 into the first heat dissipation section 1111 for a preset time when the carbon capture unit 230 switches to the desorption and regeneration state. When the carbon capture unit 230 switches to the desorption and regeneration state, the first heat dissipation section 1111 and the second heat dissipation section 1112 are interconnected. The air in the second heat dissipation section 1112 has a higher carbon dioxide concentration, so the air in the second heat dissipation section 1112 can be driven by the first blower assembly 300 to flow quickly into the first heat dissipation section 1111, which is beneficial to the efficiency of carbon dioxide adsorption by the carbon capture unit 230 when it re-enters the adsorption state.

[0048] Please refer to Figure 5 As shown, in some embodiments, the second heat dissipation section 1112 is isolated from the outside environment, and the air outlet 112 is closed in the adsorption state. Through this scheme, when the carbon capture unit 230 is in the adsorption state, the radiator 120 continuously heats the air in the second heat dissipation section 1112, causing the air temperature in the second heat dissipation section 1112 to continuously rise. After the carbon capture unit 230 switches to the desorption and regeneration state, the first heat dissipation section 1111 and the second heat dissipation section 1112 are connected, allowing the higher-temperature air in the second heat dissipation section 1112 to flow into the first heat dissipation section 1111, thereby making the heating efficiency of the air in the second heat dissipation section 1112 on the carbon capture unit 230 higher.

[0049] Based on the above description, those skilled in the art can adjust the connection between the second heat dissipation section 1112 and the outside world according to actual needs. All adjustments made based on the above embodiments are within the protection scope of this utility model.

[0050] As mentioned above, the air outlet 112 is connected to the second heat dissipation section 1112. Without departing from the inventive concept of this utility model, those skilled in the art can also place the air outlet 112 in other places.

[0051] As a preferred option, please refer to Figure 6 As shown, in some embodiments, the housing 110 is provided with an air outlet 112 communicating with the first heat dissipation section 1111; the ventilation component 500 is configured to extract indoor air and deliver it to the first heat dissipation section 1111 through the air outlet 112 during the adsorption state. Through this scheme, during the adsorption process of the carbon capture unit 230, the ventilation component 500 can continuously output indoor air with a high carbon dioxide concentration to the first heat dissipation section 1111, thereby enabling the carbon capture unit 230 to continuously contact the air with a high carbon dioxide concentration, improving the adsorption efficiency of the carbon capture unit 230.

[0052] Based on the above scheme, those skilled in the art can also improve the structure of the carbon capture unit 230 according to the orientation of the air outlet 112.

[0053] As a preferred option, please refer to Figure 2 , Figure 6 As shown, where Figure 2 It shows Figure 6 The structure of the medium carbon capture unit 230, Figure 2 The first air vent 2322 in the middle faces the opposite direction of the first direction, and the first direction is... Figure 6In some embodiments, the carbon capture unit 230 includes an adsorption structure 231, a capture body 232, a first valve 233, and a second valve 234. The capture body 232 has a capture chamber 2321, a first air vent 2322, and a second air vent 2323. Both the first air vent 2322 and the second air vent 2323 are connected to the capture chamber 2321. The first valve 233 is located at the first air vent 2322, and the second valve 234 is located at the second air vent 2323. The adsorption structure 231 is located inside the capture chamber 2321. The adsorption structure 231 can adsorb carbon dioxide at room temperature and release the adsorbed carbon dioxide when heated to a certain temperature. The carbon capture unit 230 is configured such that, in the adsorption state, both the first valve 233 and the second valve 234 are open; when the first valve 233 is open, the air outlet 112 faces the first air vent 2322.

[0054] Through the above scheme, under adsorption conditions, carbon dioxide in the air within the first heat dissipation section 1111 can enter the collection chamber 2321 through the first air vent 2322 and the second air vent 2323, and come into contact with the adsorption structure 231 located within the collection chamber 2321, thereby being captured by the adsorption structure 231. Furthermore, since the air outlet 112 faces the first air vent 2322 when the first valve 233 is open, air with a high carbon dioxide concentration flowing out of the air outlet 112 can directly flow from the first air vent 2322 into the collection chamber 2321, pass through the adsorption structure 231 within the collection chamber 2321, and then flow out from the second air vent 2323. This scheme reduces the obstruction of the air blown out of the air outlet 112 by the collection structure 2322, increases the speed at which the air blown out of the air outlet 112 flows through the adsorption structure 231, and is beneficial to improving the adsorption efficiency of the adsorption structure 231.

[0055] It should be noted that this invention does not limit the structure of the ventilation assembly 500. In some embodiments, please refer to... Figures 4 to 6 As shown, the ventilation assembly 500 includes a ventilation duct 510 and a ventilation fan 520. The ventilation fan 520 is installed inside the ventilation duct 510. One end of the ventilation duct 510 is connected to the room 11, and the other end is connected to the heat dissipation channel 111. The ventilation fan 520 can blow the air in the room 11 into the heat dissipation channel 111.

[0056] On the other hand, this utility model does not limit the structure of the carbon capture unit 230. Based on the configuration of the carbon capture unit 230 in the above embodiments, those skilled in the art can adaptively adjust the corresponding structure. For example, the number of valves and air vents can be increased or decreased, the orientation of the air vents can be adjusted, etc., and all such adjustments are within the protection scope of this utility model.

[0057] In some embodiments, the carbon capture unit 230 has an adsorption state, a vacuum state, and a desorption / regeneration state that cycle sequentially. The carbon capture unit 230 is configured such that, in the vacuum state, its interior is isolated from the heat dissipation channel 111. The collection component 210 is configured to communicate with the interior of the carbon capture unit 230 in the vacuum state and remove air from inside the carbon capture unit 230. Since the carbon capture unit 230 can adsorb carbon dioxide through the adsorption structure 231 and fix the carbon dioxide onto the adsorption structure 231, in the vacuum state, the collection component 210 can directly remove air from inside the carbon capture unit 230 by extraction, thereby reducing the air content inside the carbon capture unit 230. This facilitates the collection component 210 in collecting carbon dioxide with higher purity in the desorption / regeneration state.

[0058] Furthermore, when the carbon capture unit 230 is in a vacuum state, the first heat dissipation section 1111 and the second heat dissipation section 1112 are interconnected. Since the heat from the radiator 120 is insufficient to directly heat the carbon capture unit 230 to a state capable of desorbing carbon dioxide, connecting the first heat dissipation section 1111 and the second heat dissipation section 1112 in the vacuum state allows the hot air in the second heat dissipation section 1112 to preheat the carbon capture unit 230. This helps the carbon capture unit 230 to heat up more quickly to a state capable of desorbing carbon dioxide when in the desorption and regeneration state, accelerating the carbon dioxide desorption process and improving carbon capture efficiency.

[0059] Without departing from the inventive concept of this utility model, those skilled in the art can adjust the spatial relationship between the first heat dissipation section 1111 and the second heat dissipation section 1112. In some embodiments, please refer to Figure 1 , Figures 3 to 6 As shown, the first heat dissipation section 1111 and the second heat dissipation section 1112 are arranged horizontally.

[0060] As a preferred option, please refer to Figure 7 As shown, in some embodiments, the first heat dissipation section 1111 is located above the second heat dissipation section 1112. With the above scheme, in the desorption and regeneration state, the hot air in the second heat dissipation section 1112 can naturally flow upward into the first heat dissipation section 1111 and heat the carbon capture unit 230, and the efficiency of heating the carbon capture unit 230 with hot air is higher.

[0061] Without departing from the inventive concept of this utility model, those skilled in the art can adjust the structure of the housing 110 to achieve mutual isolation and interconnection between the first heat dissipation section 1111 and the second heat dissipation section 1112. In some embodiments, please refer to... Figure 1 , Figures 3 to 7As shown, the housing 110 also includes a heat insulation plate 113, which is slidably connected to the inner wall of the heat dissipation channel 111 to isolate or connect the first heat dissipation section 1111 and the second heat dissipation section 1112. In some embodiments, the housing 110 also includes a valve, which is disposed on the inner wall of the heat dissipation channel 111. The first heat dissipation section 1111 and the second heat dissipation section 1112 are connected to each other when the valve is open and isolated from each other when the valve is closed.

[0062] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
