Description

Technical Field

[0001] The present invention relates to the technical field of energy-saving heat exchange devices, and specifically to a heat insulation structure and an energy-saving constant temperature and humidity chamber based on the heat insulation structure. Background Art

[0002] With the progress of industrial technology and the increasing demand for energy conservation, the heat insulation structure, as the core component of the thermal management system, has been widely used in fields such as aerospace, building energy conservation, cold chain logistics, and precision instruments. Traditional heat insulation structures mainly rely on materials with low thermal conductivity (such as polyurethane foam, ceramic fiber, or aerogel composite materials) or vacuum insulation technology (such as vacuum insulation panels) to achieve thermal insulation by physically isolating or reducing the heat conduction path. However, the design goals of such structures always revolve around "static heat insulation", and their performance depends on the inherent properties of the materials. Once formed, it is difficult to dynamically adjust the heat insulation intensity according to the external environment or equipment requirements.

[0003] As a precision environmental control device, the constant temperature and humidity chamber is widely used in fields such as biopharmaceuticals, electronic component testing, and food storage. Its core requirement is to maintain high-precision stability of the temperature (±0.5°C) and humidity (±2%RH) inside the chamber. When the chamber needs to be cooled quickly, too strong heat insulation performance will instead hinder the discharge of internal heat, forcing the refrigeration system to operate overload; when the equipment is on standby or the external environmental temperature is close to the set value, it is unable to actively enhance heat exchange to utilize the natural temperature difference, resulting in repeated energy consumption.

[0004] When the existing heat insulation structure is applied to a constant temperature and humidity chamber, when the chamber needs to switch from the heat insulation state to the heat dissipation state, the material itself cannot increase the heat conduction path by pore expansion or fiber orientation adjustment, and can only rely on additional devices such as external fans or open-close dampers to discharge heat. It is impossible to achieve a controllable switch between the heat insulation and heat exchange states, and additional energy is required for auxiliary heat dissipation, so a conservative high-energy consumption mode has to be adopted to ensure stability. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a heat insulation structure and an energy-saving constant temperature and humidity chamber based on the heat insulation structure.

[0006] To solve the above technical problems, the present invention provides the following technical solutions: A heat insulation structure includes a middle layer frame.

[0009] Preferably, when the movable end of the pay-off air rod extends, the magnetic attraction pull rod can drive the movable end of the isolation curtain core to unwind from the retraction rotating shaft against the elastic force of the retraction torsion spring, and both sides of the isolation curtain core slide respectively inside the corresponding retraction track grooves. When the pay-off air rod extends to the longest state, the magnetic attraction pull rod extends into the magnetic attraction sealing groove, and the magnetic attraction pull rod and the magnetic attraction sealing groove are magnetically fixed to each other; when the movable end of the pay-off air rod shortens, under the action of the elastic force of the retraction torsion spring, the isolation curtain core can be rewound on the retraction rotating shaft again.

[0010] Preferably, a number of filling isolation bags are respectively arranged on both sides of the isolation curtain core. An aerogel storage tank and an aerogel delivery pump are further arranged inside the winding housing. The aerogel storage tank can be connected to each of the filling isolation bags through pipelines by means of the aerogel delivery pump; after the magnetic attraction pull rod extends into the magnetic attraction sealing groove, the aerogel delivery pump can convey aerogel particles from the aerogel storage tank to each of the filling isolation bags; before the magnetic attraction pull rod disengages from the magnetic attraction sealing groove, the aerogel delivery pump can convey aerogel particles from each of the filling isolation bags to the aerogel storage tank.

[0011] Preferably, a number of inner layer driving rods are rotatably arranged inside the inner layer frame. Each inner layer driving rod is fixed to a number of the inner layer heat preservation plates respectively. One end of the inner layer driving rod penetrating out of the inner layer frame is provided with an inner layer driving gear. Each of the inner layer driving gears is power-transmitted to an inner layer driving air rod through an inner layer driving rack; a number of outer layer driving rods are rotatably arranged inside the outer layer frame. Each outer layer driving rod is fixed to a number of the outer layer heat preservation plates respectively. One end of the outer layer driving rod penetrating out of the outer layer frame is provided with an outer layer driving gear.

[0012] Preferably, the power outputs of the inner layer driving air rod and the outer layer driving air rod are synchronized; only when the dynamic isolation curtain is in a winding state, the inner layer driving air rod can drive all the inner layer heat preservation plates to rotate simultaneously, causing gaps to appear due to the misalignment of adjacent inner layer heat preservation plates; only when the dynamic isolation curtain is in a winding state, the outer layer driving air rod can drive all the outer layer heat preservation plates to rotate simultaneously, causing gaps to appear due to the misalignment of adjacent outer layer heat preservation plates.

[0013] An energy-saving constant temperature and humidity box based on a heat insulation structure uses a heat insulation mechanism as described above for temperature control, and includes: a lifting base and an isolation housing. The isolation housing is arranged at the top of the lifting base. An isolation frame is arranged inside the isolation housing. An isolation door is arranged on the front of the isolation frame. The frame inside the isolation frame is filled with a number of the heat insulation mechanisms. An isolation cavity is formed by the enclosure of each of the heat insulation mechanisms and the isolation door.

[0014] Preferably, a humidity constant adjustment mechanism is disposed inside the isolation housing and outside the isolation frame. The humidity constant adjustment mechanism includes an exhaust fan, an intake fan, a humidifying tank, and a selective intake valve. The selective intake valve can control whether the intake path of the intake fan passes through the humidifying tank; the exhaust fan and the intake fan can adjust the humidity inside the isolation chamber. During the humidity adjustment process inside the isolation chamber, the dynamic isolation curtains of the heat insulation mechanism near the exhaust fan and the intake fan are in a retracted state.

[0015] Preferably, when dehumidifying the isolation chamber, the exhaust fan can unidirectionally discharge the gas inside the isolation chamber to the outside of the isolation housing. At the same time, the selective intake valve controls the intake fan to be directly communicated with the outside of the isolation housing, and the intake fan can supply air from the outside of the isolation housing to the inside of the isolation chamber; when humidifying the isolation chamber, the selective intake valve controls the communication between the intake fan and the humidifying tank, and the intake fan can supply the air entering from the outside of the isolation housing to the inside of the isolation chamber after passing through the humidifying tank, and the exhaust fan can unidirectionally discharge the gas inside the isolation chamber to the outside of the isolation housing.

[0016] Compared with the prior art, the present invention provides a heat insulation structure and an energy-saving constant temperature and humidity box based on the heat insulation structure, having the following beneficial effects: 1. For this heat insulation structure, when the dynamic isolation curtains are in a filled state, each adjacent inner thermal insulation board remains in contact, and each adjacent outer thermal insulation board also remains in contact. The two sides of the dynamic isolation curtains are respectively in contact with the inner thermal insulation layer and the outer heat insulation layer, and heat insulation can be achieved through the cooperation of the dynamic isolation curtains with the inner thermal insulation layer and the outer heat insulation layer; when the dynamic isolation curtains are in a retracted state, the dynamic isolation curtains are recessed into the middle frame. There are gaps between each adjacent inner thermal insulation board, and there are also gaps between each adjacent outer thermal insulation board, so that heat can pass through the gaps existing between each adjacent inner thermal insulation board, the space where the middle frame is exposed after the dynamic isolation curtains are retracted, and the gaps existing between each adjacent outer thermal insulation board to exchange heat between the inside and outside of this heat insulation structure; thus, through the setting of this heat insulation structure, the conversion between heat insulation and heat exchange can be carried out between the internal space and the external space set by the heat insulation structure, so that heat exchange can be effectively carried out and blocked according to actual needs, and further, the use conditions of the heat insulation structure can be effectively coordinated.

[0017] 2. In this heat insulation structure, when the unwinding air rod extends to the longest state, the magnetic attraction pull rod extends into the magnetic attraction sealing groove, and the magnetic attraction pull rod and the magnetic attraction sealing groove are magnetically fixed to each other. As a result, the two sides of the curtain core are sealed through the magnetic attraction between the magnetic attraction pull rod and the magnetic attraction sealing groove, and the two sides of the curtain core are sealed from the corresponding winding track grooves. The aerogel delivery pump can deliver and fill aerogel particles from the aerogel storage tank to each filling isolation bag, so that the temperature insulation ability on both sides of the curtain core can be enhanced by the aerogel particles in each filling isolation bag. Furthermore, the cooperation between each filling isolation bag and the curtain core can effectively achieve the purpose of heat insulation.

[0018] 3. In this heat insulation structure, only when the dynamic isolation curtain is in the winding state, the inner layer driving air rod can drive all the inner layer heat insulation plates to rotate simultaneously, causing gaps to appear due to the misalignment of adjacent inner layer heat insulation plates. Only when the dynamic isolation curtain is in the winding state, the outer layer driving air rod can drive all the outer layer heat insulation plates to rotate simultaneously, causing gaps to appear due to the misalignment of adjacent outer layer heat insulation plates. Thus, heat exchange can occur between the inside and outside of this heat insulation structure through the gaps formed by the misalignment of adjacent inner layer heat insulation plates, the space of the middle frame where the curtain core is wound and open, and the gaps formed by the misalignment of adjacent outer layer heat insulation plates.

[0019] 4. In this energy-saving constant temperature and humidity box based on the heat insulation structure, an isolation cavity is formed by enclosing between each heat insulation mechanism and the isolation door. The semiconductor heating and semiconductor refrigeration elements arranged inside the isolation frame can heat or cool the inside of the isolation cavity to keep the temperature inside the isolation cavity constant. The temperature is fully isolated by each inner layer heat insulation plate of each heat insulation mechanism, the curtain core enhanced by aerogel particles in each filling isolation bag, and each outer layer heat insulation plate, so that heat exchange can be reduced, and energy can be effectively saved. When dehumidifying the isolation cavity, the exhaust fan can unidirectionally discharge the gas inside the isolation cavity to the outside of the isolation shell. At the same time, the intake valve is selected to control the intake fan to be directly connected to the outside of the isolation shell, and the intake fan can supply gas from the outside of the isolation shell to the inside of the isolation cavity for effective dehumidification. When humidifying the isolation cavity, the intake valve is selected to control the intake fan to be connected to the humidifying tank. The intake fan can supply the air entering from the outside of the isolation shell to the inside of the isolation cavity after passing through the humidifying tank, and the exhaust fan can unidirectionally discharge the gas inside the isolation cavity to the outside of the isolation shell for effective humidification.

Detailed implementation manners

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0023] As introduced in the background art, there are deficiencies in the prior art. To solve the above technical problems, the present application proposes a heat insulation structure and an energy-saving constant temperature and humidity box based on the heat insulation structure. Embodiment 1

[0024] Please refer to Figures 1 - 8 , a heat insulation structure, including a middle layer frame 1, a heat preservation inner layer 2 is arranged inside the middle layer frame 1, a heat insulation outer layer 3 is arranged outside the middle layer frame 1, a dynamic isolation curtain 4 is installed inside the frame of the middle layer frame 1, and each dynamic isolation curtain 4 can be converted between a retracted state and a filled state; the heat preservation inner layer 2 includes an inner layer frame 21 and a plurality of inner layer heat preservation plates 22, and each inner layer heat preservation plate 22 is rotatably connected to the inner layer frame 21, and each inner layer heat preservation plate 22 can rotate synchronously; the heat insulation outer layer 3 includes an outer layer frame 31 and a plurality of outer layer heat preservation plates 32, and each outer layer heat preservation plate 32 is rotatably connected to the outer layer frame 31, and each outer layer heat preservation plate 32 can rotate synchronously; when the dynamic isolation curtain 4 is in the filled state, adjacent inner layer heat preservation plates 22 are kept in contact with each other, and adjacent outer layer heat preservation plates 32 are also kept in contact with each other, and both sides of the dynamic isolation curtain 4 are respectively in contact with the heat preservation inner layer 2 and the heat insulation outer layer 3; when the dynamic isolation curtain 4 is in the retracted state, the dynamic isolation curtain 4 retracts into the middle layer frame 1, there are gaps between adjacent inner layer heat preservation plates 22, and there are also gaps between adjacent outer layer heat preservation plates 32.

[0025] This heat insulation structure can be set at any position that needs heat preservation, constant temperature or heat insulation to isolate the transmission of temperature. In specific use, the heat insulation structure can be converted between an open state and a heat insulation state according to the retracted state and the filled state of the dynamic isolation curtain 4; when the dynamic isolation curtain 4 is in the filled state, adjacent inner layer heat preservation plates 22 are kept in contact with each other, adjacent outer layer heat preservation plates 32 are also kept in contact with each other, and both sides of the dynamic isolation curtain 4 are respectively in contact with the heat preservation inner layer 2 and the heat insulation outer layer 3, so that heat insulation can be carried out through the cooperation of the dynamic isolation curtain 4 with the heat preservation inner layer 2 and the heat insulation outer layer 3; when the dynamic isolation curtain 4 is in the retracted state, the dynamic isolation curtain 4 retracts into the middle layer frame 1, there are gaps between adjacent inner layer heat preservation plates 22, and there are also gaps between adjacent outer layer heat preservation plates 32, so that heat can pass through the gaps between the inner layer heat preservation plates 22, the space where the middle layer frame 1 is exposed after the dynamic isolation curtain 4 is retracted, and the gaps between the outer layer heat preservation plates 32 to exchange heat between the inside and outside of this heat insulation structure; thus, through the setting of this heat insulation structure, the conversion between heat insulation and heat exchange can be carried out between the internal space and the external space where the heat insulation structure is set, so that the heat exchange can be effectively carried out and blocked according to the actual needs, and further the use conditions of the heat insulation structure can be effectively matched. Example 2

[0026] Please refer to Figures 1 - 8 , which is different from the above embodiment in that the dynamic isolation curtain 4 includes a winding housing 41 and an isolation curtain core 42. A winding rotating shaft 43 is arranged inside the winding housing 41, and a winding torsion spring 44 is arranged on one side of the winding rotating shaft 43. The fixed end of the isolation curtain core 42 is fixed to the winding rotating shaft 43, and a magnetic attraction pull rod 45 is arranged at the movable end of the isolation curtain core 42; the winding housing 41 is arranged inside the middle layer frame 1, and winding track grooves 11 are opened on both sides of the winding housing 41 inside the middle layer frame 1, and a magnetic attraction sealing groove 12 is arranged on the side of the middle layer frame 1 away from the winding housing 41 inside the middle layer frame 1.

[0027] Both sides of the isolation curtain core 42 are respectively embedded inside the two winding track grooves 11, and both ends of the magnetic attraction pull rod 45 are also respectively embedded inside the two winding track grooves 11; a pay-off air rod 13 is arranged at one end of the winding track groove 11 close to the winding housing 41, and the movable end of the pay-off air rod 13 is fixed to the magnetic attraction pull rod 45.

[0028] When the movable end of the pay-off air rod 13 extends, the magnetic attraction pull rod 45 can drive the movable end of the isolation curtain core 42 to unwind from the winding rotating shaft 43 against the elastic force of the winding torsion spring 44, and both sides of the isolation curtain core 42 slide inside the corresponding winding track grooves 11 respectively. When the pay-off air rod 13 extends to the longest state, the magnetic attraction pull rod 45 extends into the magnetic attraction sealing groove 12, and the magnetic attraction pull rod 45 is magnetically fixed to the magnetic attraction sealing groove 12; when the movable end of the pay-off air rod 13 shortens, under the action of the elastic force of the winding torsion spring 44, the isolation curtain core 42 can be rewound on the winding rotating shaft 43 again.

[0029] A number of filling isolation bags 46 are respectively arranged on both sides of the isolation curtain core 42, and an aerogel storage tank and an aerogel delivery pump are also arranged inside the winding housing 41. The aerogel storage tank can be communicated with each filling isolation bag 46 through pipelines by the aerogel delivery pump; after the magnetic attraction pull rod 45 extends into the magnetic attraction sealing groove 12, the aerogel delivery pump can convey aerogel particles from the aerogel storage tank to each filling isolation bag 46; before the magnetic attraction pull rod 45 disengages from the magnetic attraction sealing groove 12, the aerogel delivery pump can convey aerogel particles from each filling isolation bag 46 to the aerogel storage tank.

[0030] Thus, during specific use, the movable end of the magnetic attraction pull rod 45 drives the isolation curtain core 42 to unwind from the winding rotating shaft 43 against the elastic force of the winding torsion spring 44, and both sides of the isolation curtain core 42 slide inside the corresponding winding track grooves 11 respectively. When the winding air rod 13 extends to the longest state, the magnetic attraction pull rod 45 extends into the magnetic attraction sealing groove 12, and magnetic attraction fixation is achieved between the magnetic attraction pull rod 45 and the magnetic attraction sealing groove 12. Thus, sealing is achieved between the magnetic attraction pull rod 45 and the magnetic attraction sealing groove 12, and sealing is achieved between both sides of the isolation curtain core 42 and the corresponding winding track grooves 11. And through the aerogel delivery pump, aerogel particles can be transported and filled from the aerogel storage tank to each filling isolation bag 46 (the filling isolation bag 46 is a structure with elasticity), and the temperature isolation ability on both sides of the isolation curtain core 42 can be enhanced through the aerogel particles inside each filling isolation bag 46. Furthermore, the purpose of heat insulation can be effectively achieved through the cooperation of each filling isolation bag 46 and the isolation curtain core 42; Before the movable end of the winding air rod 13 shortens, through the gel delivery pump, aerogel particles can be transported from each filling isolation bag 46 to the aerogel storage tank, and the aerogel particles are recovered, and each filling isolation bag 46 is restored to the smallest state. Furthermore, when the movable end of the winding air rod 13 shortens, under the elastic force of the winding torsion spring 44, the isolation curtain core 42 can drive each filling isolation bag 46 in the smallest state on both sides to wind around the winding rotating shaft 43 again, and thus the middle layer frame 1 can be opened, and furthermore, heat can pass through the vacant area of the middle layer frame 1 and heat exchange can be carried out.

[0032] The power output of the inner driving air cylinder 26 and the outer driving air cylinder 36 is synchronized; only when the dynamic isolation curtain 4 is in the retracted state, the inner driving air cylinder 26 can drive all the inner heat preservation plates 22 to rotate simultaneously, causing adjacent inner heat preservation plates 22 to be misaligned and creating gaps; only when the dynamic isolation curtain 4 is in the retracted state, the outer driving air cylinder 36 can drive all the outer heat preservation plates 32 to rotate simultaneously, causing adjacent outer heat preservation plates 32 to be misaligned and creating gaps.

[0033] In specific use, when the dynamic isolation curtain 4 is in the filling state, the temperature can be fully isolated by each inner heat preservation plate 22, the isolation curtain core 42 enhanced by aerogel particles inside each filling isolation bag 46, and each outer heat preservation plate 32; only when the dynamic isolation curtain 4 is in the retracted state, the inner driving air cylinder 26 can drive all the inner heat preservation plates 22 to rotate simultaneously, causing adjacent inner heat preservation plates 22 to be misaligned and creating gaps, and only when the dynamic isolation curtain 4 is in the retracted state, the outer driving air cylinder 36 can drive all the outer heat preservation plates 32 to rotate simultaneously, causing adjacent outer heat preservation plates 32 to be misaligned and creating gaps, so that heat exchange can occur between the inside and outside of this heat insulation structure through the gaps formed by the misalignment of adjacent inner heat preservation plates 22, the space of the middle layer frame 1 where the isolation curtain core 42 is retracted and opened, and the gaps formed by the misalignment of adjacent outer heat preservation plates 32.

The humidity constant adjustment mechanism 9 includes an exhaust fan 91, an intake fan 92, a humidifying tank 93, and a selection intake valve 94. The selection intake valve 94 can control whether the intake path of the intake fan 92 passes through the humidifying tank 93; the exhaust fan 91 and the intake fan 92 can adjust the humidity inside the isolation cavity. During the humidity adjustment process inside the isolation cavity, the dynamic isolation curtain 4 of the heat insulation mechanism close to the exhaust fan 91 and the intake fan 92 is in the retracted state.

[0036] When dehumidifying the isolation chamber, the exhaust fan 91 can unidirectionally discharge the gas inside the isolation chamber to the outside of the isolation housing 6. At the same time, the intake valve 94 is selected to control the intake fan 92 to be directly connected to the outside of the isolation housing 6, and the intake fan 92 can supply air from the outside of the isolation housing 6 to the inside of the isolation chamber.

[0037] During use, an isolation chamber can be formed by enclosing between each heat insulation mechanism and the isolation door 8. The inside of the isolation chamber can be heated or cooled by the semiconductor heating and semiconductor refrigeration elements arranged inside the isolation frame 7 to keep the temperature inside the isolation chamber constant. The temperature can be fully isolated by each inner thermal insulation board 22 of each heat insulation mechanism, the isolation curtain core 42 enhanced by aerogel particles inside each filling isolation bag 46, and each outer thermal insulation board 32, so that heat exchange can be reduced, and thus energy can be effectively saved. When dehumidifying the isolation chamber, the exhaust fan 91 can unidirectionally discharge the gas inside the isolation chamber to the outside of the isolation housing 6. At the same time, the intake valve 94 is selected to control the intake fan 92 to be directly connected to the outside of the isolation housing 6, and the intake fan 92 can supply air from the outside of the isolation housing 6 to the inside of the isolation chamber for effective dehumidification.
