Technical Field
[0001] The present invention relates to the technical field of automobile temperature control, and in particular to a temperature control device for an automobile compartment and a temperature control method thereof. Background Art

[0017] Temperature control method for automobile compartment
[0018] A1. By installing double-layer glass in the vehicle windows and arranging a temperature control component therein, excess heat or cold in the vehicle can be absorbed and stored while the vehicle is running, and slowly released after parking and shutting down, achieving continuous temperature regulation in the vehicle without the need for air conditioning. The first airbag in the temperature control component is a closed structure filled with phase-change capsules. When expanding, the capsules adhere to the inner wall of the double-layer glass to enhance thermal conductivity. When contracting, they detach from the glass to reduce the heat exchange rate, thereby achieving controllable heat release and improving temperature control efficiency. The stabilization component installed in the vehicle door serves as an auxiliary energy storage module, synchronously absorbing heat energy in the vehicle and working in conjunction with the temperature control component to form integrated multi-point temperature control for doors and windows, significantly expanding the temperature control coverage and slow-release effect.
[0019] A2. The flat strip shape allows the first airbag to fully utilize the edge cavity space inside the double-layer glass, without blocking the light transmission line of the middle part of the window, while effectively covering the main channel area for heat exchange in the upper and lower directions of the window. Because the first airbag is configured as a flat strip structure, its expansion direction is mainly along the direction perpendicular to the glass surface, with slight deformation. Therefore, it can be stably attached to the inner wall of the double-layer glass during operation, achieving large-area thermal contact.
[0020] A3. When the temperature inside the vehicle gradually rises, the door, as part of the vehicle body, is prone to absorbing heat or cold from the interior environment. At this time, the second airbag and the phase change pad are attached to the inner wall of the door, which can first absorb the heat or cold conducted from the door body and store it through the phase change material inside the phase change pad. When the vehicle is turned off, as the temperature of the vehicle changes, the heat or cold stored in the phase change pad can be slowly released to the surface of the door interior panel through the reverse process of phase change, and indirectly radiated to the interior space of the vehicle, maintaining the stability of the vehicle temperature for a short period of time.
[0021] Beneficial effects
[0022] The temperature control device of the above-mentioned automobile compartment can store the heat or cold generated in the car during driving through the compartment temperature control mechanism, and slowly release it after the vehicle stops, which can effectively delay the drastic fluctuation of the compartment temperature in a short period of time. Compared with the problem of rapid increase or decrease in the temperature in the car after the vehicle is turned off in the prior art, it can maintain the relative stability of the interior environment in a short time, especially in high temperature in summer or low temperature in winter, and effectively avoid the problems of stuffiness, biting cold, etc. when the passengers re-enter the compartment after a short stop.

[0041] The following combination Figures 1-10 The present invention describes a temperature control device for a vehicle compartment and a temperature control method thereof.
[0042] In one embodiment, a temperature control device for a car compartment includes a compartment door 100, a window 200 is provided on one side of the compartment door 100, and a double-layer glass 210 is fixedly installed inside the compartment window 200; a compartment temperature control mechanism 300, the compartment temperature control mechanism 300 includes a sealing belt 310, a temperature control component 320 and a stabilization component 330, the sealing belt 310 is fixedly installed on the outside of the double-layer glass 210, a gap is provided between the double-layer glass 210, the temperature control component 320 is provided inside the gap, and the stabilization component 330 is provided inside the compartment door 100; wherein, the temperature control component 320 includes two first airbags 321 fixedly installed inside the double-layer glass 210, and a plurality of phase change capsules 325 are provided inside the two first airbags 321.
[0043] In this embodiment, by providing double-layer glass 210 in the vehicle window 200 and a temperature control assembly 320 therein, it is possible to absorb and store excess heat or cold during vehicle operation, and then slowly release it after the vehicle is parked and turned off, thereby achieving continuous regulation of the vehicle interior temperature without relying on the air conditioning system. The first airbag 321 in the temperature control assembly 320 adopts a closed structure and is filled with phase-change capsules 325. When the first airbag 321 is inflated, the phase-change capsules 325 can be attached to the inner surface of the double-layer glass 210 to improve heat conduction efficiency. When the first airbag 321 is deflated, it detaches from the double-layer glass 210, reducing the heat exchange rate and achieving active regulation of the heat release process, significantly improving the energy storage utilization rate and temperature control effect. The stabilization assembly 330 is provided in the internal structure of the vehicle door 100 and can serve as an auxiliary energy storage unit to synchronously absorb and store excess heat energy in the vehicle. It forms a cooperative working mechanism with the temperature control assembly 320 of the vehicle window 200, expanding the range of temperature control and achieving a multi-point passive temperature control effect for the integrated door and window.
[0044] The setting of the sealing strip 310 can form a good sealing structure at the edge of the double-layer glass 210, preventing heat leakage or external air infiltration during the expansion of the first airbag 321, while ensuring the stability of the working environment of the internal phase change capsule 325, and improving the sealing and service life of the system.
[0045] like Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 As shown, the temperature control component 320 also includes two heat-conducting plates 326 arranged on the outside of the multiple phase change capsules 325. The multiple phase change capsules 325 inside the same first airbag 321 are all equidistantly distributed. Two limiting belts 322 are fixedly installed inside the double-layer glass 210, and the two limiting belts 322 are fixedly installed on the adjacent side of the two first airbags 321.
[0046] In this embodiment, during use, the first airbag 321 in the temperature control assembly 320 expands and adjusts, causing the multiple phase-change capsules 325 within it to adhere to the inner wall of the double-glazed window 210. At this point, the phase-change capsules 325 absorb heat transmitted from the vehicle window 200 and store some of this heat energy within them through a phase-change heat absorption process. A thermally conductive sheet 326 disposed on the outer surface of the phase-change capsules 325 evenly directs heat to the surfaces of the multiple phase-change capsules 325, improving phase-change efficiency and heat exchange rate, thereby rapidly absorbing excess heat energy within the vehicle. When the vehicle is turned off or the air conditioner stops operating, the gas pressure in the first airbag 321 is released, causing it to gradually contract, driving the thermally conductive sheet 326 and phase-change capsules 325 away from the inner wall of the double-glazed window 210, achieving a controlled, sustained release. During this process, the phase change capsule 325 gradually releases the absorbed heat to the inner side of the double-layer glass 210, which radiates or conducts the heat into the vehicle through the double-layer glass 210, thereby maintaining the short-term stability of the vehicle compartment temperature. The two limiting belts 322 set inside the double-layer glass 210 can provide stable support for the first airbag 321, preventing it from offsetting or rotating due to changes in expansion pressure, thereby ensuring that the deformation direction is stable and controllable.
[0047] A stabilizing layer 327 is fixedly mounted on the outer side of the phase change capsule 325 , a protective layer 328 is fixedly mounted on the outer side of the stabilizing layer 327 , and two heat conducting sheets 326 are fixedly mounted on the outer side of the protective layer 328 .
[0048] In this embodiment, the multiple phase change capsules 325 in the first airbag 321 are divided into two types, high-temperature type and low-temperature type, according to different heat storage or cold storage functions. They are staggered and filled in different partitions of the first airbag 321. The high-temperature phase change capsules 325 use hexadecane phase change material with a phase change temperature set at 28-32°C for heat absorption and slow release for cooling in summer. The low-temperature phase change capsules 325 use tetradecane material with a phase change temperature set at 16-20°C for heat storage and slow release for heating in winter. Through the zoning arrangement, they work together and can be used year-round, realizing two-way regulation of the thermal environment inside the vehicle when the vehicle is stationary.
[0049] It should be noted that when the ambient temperature rises above its phase transition point, the internal material of the phase change capsule 325 absorbs heat and undergoes a solid-to-liquid phase transition, thereby storing heat. When the temperature drops below the phase transition point, the phase change material solidifies from liquid to solid, releasing the previously stored heat during the phase transition, creating a slow-release heating effect. Through this physical change process, the phase change capsule 325 can regulate and maintain the thermal energy of the vehicle interior without relying on any external energy source.
[0050] It should be noted that the stabilization layer 327 is a flexible polymer matrix composite layer. Its main function is to limit the disordered movement and accumulation of the phase change capsules 325 inside the first airbag 321 through physical support, ensuring that the capsules always maintain an equidistant and flat distribution during each expansion or contraction of the first airbag 321, thereby improving the uniformity of the fit between the heat transfer surface and the double-layer glass 210. On the other hand, the stabilization layer 327 itself has a certain thermal conductivity, which can help diffuse the heat conducted by the thermal conductive plate 326 to the surface of the phase change capsule 325, thereby improving the thermal response rate.
[0051] The heat conducting sheet 326 is configured in an “O” shape, and the two heat conducting sheets 326 are in contact with the inner wall of the first airbag 321 at their respective sides away from each other.
[0052] In this embodiment, when the first airbag 321 expands close to the double-layer glass 210, the outer side of the heat conductive plate 326 can form surface contact with the inner wall of the double-layer glass 210, thereby quickly obtaining heat or cold conducted from the interior of the vehicle, and improving the absorption speed and efficiency of the phase change material.
[0053] The two first air bags 321 are respectively located on the top wall and the bottom wall of the double-layer glass 210 , and the first air bags 321 are configured in a flat strip shape.
[0054] In this embodiment, the flat strip shape allows the first airbag 321 to fully utilize the edge cavity space inside the double-layer glass 210, without blocking the light transmission line of sight in the middle of the vehicle window 200, and effectively covering the main channel area for heat exchange in the upper and lower directions of the vehicle window 200. Since the first airbag 321 is configured as a flat strip structure, its expansion direction is mainly along the direction perpendicular to the glass surface with slight deformation. Therefore, it can be stably attached to the inner wall of the double-layer glass 210 during operation to achieve large-area thermal contact. At the same time, the strip structure has good adhesion and flexibility, and will not produce bulging or partial suspension during the expansion process. It can enable the phase change capsule 325 and the heat conductive sheet 326 to be evenly deployed on the inner wall of the glass, forming a continuous and stable heat conduction path. The first airbag 321 is respectively arranged at the top and bottom of the vehicle window 200, and can simultaneously absorb and slowly release thermal radiation from above and below the vehicle window 200, further expanding the temperature control coverage range and improving the temperature control balance.
[0055] A connecting pipe 324 is fixedly installed between the two first airbags 321 . A telescopic pipe 323 is fixedly connected to the bottom of the first airbag 321 at the bottom. The other end of the telescopic pipe 323 extends to the inside of the vehicle door 100 and is fixedly connected to a first micro pump 329 .
[0056] In this embodiment, the two first airbags 321 are connected by a connecting tube 324 to achieve a balanced flow of gas between the two first airbags 321, so that the first airbags 321 located on the upper and lower sides of the double-layer glass 210 can move synchronously during inflation or deflation, maintaining a symmetrical expansion and contraction state. The bottom of the first airbag 321 located at the bottom is connected to the first micro pump 329 inside the vehicle door 100 through a telescopic tube 323. The telescopic tube 323 has flexible and compressible characteristics and can be freely extended and bent within the structure of the vehicle door 100 to adapt to the deformation and vibration of the vehicle door 100 during opening and closing, ensuring the continuity and sealing of the gas path connection. The first micro pump 329 is a low-power gas drive device on the vehicle, which is used to actively fill the first airbag 321 according to the control signal. Or extract gas to control the expansion and contraction state of the first airbag 321. When heat absorption and storage are required, the first micro pump 329 is controlled to inflate the first airbag 321. The two first airbags 321 expand synchronously through the connecting tube 324, so that the temperature control component 320 fits the inner wall of the double-layer glass 210, and thermal contact between the phase change capsule 325 and the glass is achieved. When slow release of stored energy is required, the first micro pump 329 reversely pumps air, and the first airbag 321 slowly retracts, driving the phase change capsule 325 to separate from the inner wall of the glass, reducing the heat exchange efficiency, thereby controlling the release rate. The connecting tube 324 and the telescopic tube 323 can realize synchronous pneumatic adjustment of the two first airbags 321, and the power source first micro pump 329 is arranged inside the car door 100, effectively saving the space in the glass cavity.
[0057] like Figure 2 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10 As shown, the stabilizing assembly 330 includes a second airbag 331 fixedly mounted inside the vehicle door 100 , and a phase change pad 332 fixedly mounted inside the second airbag 331 .
[0058] In this embodiment, the second airbag 331 has a flat bag-like structure and is attached to the cavity area between the interior panel of the vehicle door 100 and the door body structure. A phase change pad 332 is fixedly installed inside the second airbag 331. The phase change pad 332 is composed of a composite of phase change material and a flexible substrate. The overall structure is sheet-like and can cover the main heat exchange area inside the vehicle door 100. When the temperature inside the vehicle gradually rises, the vehicle door 100, as a part of the vehicle body, is easy to absorb heat or cold from the vehicle interior environment. At this time, the second airbag 331 and the phase change pad 332 are attached to the inner wall of the vehicle door 100, which can first absorb the heat or cold conducted from the door body and store it through the phase change material inside the phase change pad 332. When the vehicle is turned off, as the vehicle cabin temperature changes, the heat or cold stored in the phase change pad 332 can be slowly released to the surface of the interior panel of the vehicle door 100 through the phase change reverse process, and indirectly radiated to the interior space of the vehicle cabin, thereby maintaining the stability of the vehicle cabin temperature for a short period of time.
[0059] The second airbag 331 is configured as a U-shaped structure, and the shape of the phase change pad 332 is adapted to the second airbag 331 .
[0060] In this embodiment, the U-shaped second airbag 331, when inflated, evenly props up the four sides of the phase-change backing plate 332, allowing it to fit snugly against the interior panel of the vehicle door 100. This effectively enhances heat exchange efficiency between the backing plate and the interior air. The central void allows for the removal of audio components, electronic control wiring, or handle mechanisms within the door, improving structural adaptability.
[0061] A plurality of deformation grooves 333 are formed on both side surfaces of the phase change pad 332 , and the plurality of deformation grooves 333 are equidistantly distributed.
[0062] In this embodiment, when the second airbag 331 expands and drives the phase change pad 332 to fit the surface of the interior panel of the vehicle door 100, the deformation groove 333 can automatically form local bends at different positions according to the slight curvature of the door surface, so that the phase change pad 332 can fit the interior panel better as a whole, avoiding the occurrence of overhanging or warping, and ensuring that the phase change pad 332 forms a stable thermal contact surface during the large-area attachment process. At the same time, the deformation groove 333, as a weakened area of the surface structure, can absorb local thermal expansion and contraction stress, prevent the phase change pad 332 from curling, deformation or fatigue cracking under thermal cycles, and significantly improve its mechanical stability for long-term use.
[0063] A second micro pump 334 is provided at the bottom of the second airbag 331, a guide plate 336 is provided at the top of the second micro pump 334, a plurality of shunt tubes 337 are fixedly installed on the top of the guide plate 336, and the shunt tubes 337 are all connected to the interior of the second airbag 331. The output end of the second micro pump 334 is connected to the guide plate 336, and a controller 335 is fixedly installed at the bottom of the guide plate 336.
[0064] In this embodiment, when the temperature in the vehicle cabin rises or falls to a preset threshold, the controller 335 controls the second micro pump 334 to start, outputs air flow to the guide plate 336, and evenly injects gas into the second airbag 331 through multiple diversion tubes 337, so that the phase change pad 332 is fully in contact with the surface of the interior panel of the vehicle door 100, thereby achieving synchronous absorption of heat or cold in the vehicle. When the set release condition is reached, the controller 335 adjusts the second micro pump 334 to run in reverse or stop, so that the second airbag 331 slowly retracts and releases the stored heat energy, thereby completing a passive temperature control cycle. By setting the guide plate 336 and multiple diversion tubes 337, not only is the gas flow distribution optimized and the uniformity of the second airbag 331 during the expansion process improved, but it can also effectively reduce the problems of local air stagnation, uneven air pressure or delayed inflation time, thereby improving the response speed and temperature control accuracy.
[0065] Temperature control method for automobile compartment
[0066] A1. By installing double-glazed glass 210 in the vehicle window 200 and arranging a temperature control assembly 320 therein, excess heat or cold within the vehicle can be absorbed and stored while the vehicle is in operation, and slowly released after the vehicle is parked and turned off, achieving continuous temperature regulation within the vehicle without the need for air conditioning. The first airbag 321 within the temperature control assembly 320 is a closed structure filled with phase-change capsules 325. When expanded, the capsules adhere to the inner wall of the double-glazed glass 210 to enhance thermal conductivity. When contracted, they detach from the glass, reducing the heat exchange rate. This allows for controllable heat release and improves temperature control efficiency. The stabilization assembly 330 within the vehicle door 100 acts as an auxiliary energy storage module, simultaneously absorbing heat energy within the vehicle. Working in conjunction with the temperature control assembly 320, it forms an integrated multi-point temperature control system for the doors and windows, significantly expanding the temperature control coverage and slow-release effect.
[0067] A2. The flat strip shape allows the first airbag 321 to fully utilize the edge cavity space inside the double-layer glass 210, without blocking the light transmission line of the middle part of the vehicle window 200, and effectively covering the main channel area for heat exchange in the upper and lower directions of the vehicle window 200. Since the first airbag 321 is configured as a flat strip structure, its expansion direction is mainly along the direction perpendicular to the glass surface with slight deformation. Therefore, it can be stably attached to the inner wall of the double-layer glass 210 during operation, achieving large-area thermal contact.
[0068] A3. When the temperature inside the vehicle gradually rises, the vehicle door 100, as a part of the vehicle body, easily absorbs heat or cold from the vehicle interior environment. At this time, the second airbag 331 and the phase change pad 332 are attached to the inner wall of the vehicle door 100, which can first absorb the heat or cold conducted from the door body and store it through the phase change material inside the phase change pad 332. When the vehicle is turned off, as the vehicle compartment temperature changes, the heat or cold stored in the phase change pad 332 can be slowly released to the surface of the interior panel of the vehicle door 100 through the reverse process of phase change, and indirectly radiated to the interior space of the vehicle compartment, thereby maintaining the stability of the vehicle compartment temperature for a short period of time.
[0069] Working principle: Through the two energy storage temperature control structures set inside the car window 200 and the car door 100, the absorption, storage and slow release of heat or cold in the car are realized, so that the short-term stability of the temperature in the car is maintained after the vehicle is turned off or the air conditioner is turned off. The car window 200 is partially provided with double-layer glass 210, and two first airbags 321 are installed inside, located at the top and bottom of the glass respectively. The first airbag 321 is a flat strip structure, filled with multiple phase change capsules 325, and the outside of the capsule is provided with a stabilizing layer 327, a protective layer 328 and an "O"-shaped heat conductive sheet 326 in sequence. When the first micro pump 329 is inflated through the telescopic tube 323, the first airbag 321 expands close to the glass, and the heat conductive sheet 326 conducts the heat in the car to the phase change capsule 325, completing heat absorption and energy storage. When the air is deflated, the first airbag 321 contracts, and the phase change capsule 325 is compressed. The variable capsule 325 moves away from the glass and begins to release heat slowly. The two first airbags 321 are connected by a connecting tube 324 to ensure synchronous expansion. The stabilizing component 330 inside the car door 100 includes a second airbag 331 and an internally fixed phase-change pad 332. The surface of the phase-change pad 332 is provided with multiple deformation grooves 333. The second micro pump 334 controls the inflation and deflation of the second airbag 331 through a guide plate 336 and multiple shunt pipes 337, so that the phase-change pad 332 can fit or detach from the interior panel of the car door 100, completing the synchronous absorption and slow release of heat. The controller 335 controls the working status of the first micro pump 329 and the second micro pump 334 according to the temperature inside the car. The overall structure is centered on the inflation and deflation drive structure of the first airbag 321 and the second airbag 331 to achieve a temperature control cycle of fitting, absorbing heat, and shrinking and slow release.

The specific models can be selected according to actual needs. At the same time, the first micro pump and the second micro pump can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.
