Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of energy-saving heat exchange devices, in particular to a heat insulation structure and an energy-saving constant temperature and humidity box based on the heat insulation structure. BACKGROUND

[0002] With the progress of industrial technology and the increasing demand for energy saving, heat insulation structures, as the core components of thermal management systems, have been widely used in aerospace, building energy saving, 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), which achieve thermal resistance by physically isolating or reducing the heat conduction path. However, the design goal of such structures is always focused on "static insulation", and their performance depends on the inherent properties of the materials, which are difficult to dynamically adjust the insulation strength according to the external environment or equipment requirements once they are formed.

[0003] Constant temperature and humidity boxes, as precision environmental control equipment, are widely used in biopharmaceuticals, electronic component testing, food storage, and other fields. Their core requirement is to maintain high-precision stability of the temperature (±0.5℃) and humidity (±2%RH) inside the box. However, when the box needs to be rapidly cooled, the excessive insulation performance hinders the removal of internal heat, forcing the refrigeration system to operate under heavy load. When the equipment is on standby or the external environment temperature is close to the set value, it cannot actively enhance heat exchange to utilize natural temperature differences, resulting in repeated energy consumption.

[0004] The existing heat insulation structure applied in the constant temperature and humidity box cannot increase the heat conduction path by expanding the pores or adjusting the fiber orientation when the box needs to switch from the insulation state to the heat dissipation state. It can only rely on additional devices such as external fans or on-off dampers to achieve heat removal. It cannot achieve controllable switching between insulation and heat exchange states, requires additional energy for auxiliary cooling, and is forced to adopt a conservative high-energy consumption mode to ensure stability.

DETAILED DESCRIPTION

[0035] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all the other embodiments obtained by those of ordinary skill in the art without creative efforts are within the scope of the present application.

[0036] As introduced in the background, the deficiencies in the prior art exist. In order to solve the above technical problems, the present application provides a heat insulation structure and an energy-saving constant temperature and humidity box based on the heat insulation structure. Embodiment one

[0037] Please refer to Figures 1-8 A heat insulation structure comprises a middle layer frame 1, an inner heat preservation layer 2 arranged on the inner side of the middle layer frame 1, an outer heat insulation layer 3 arranged on the outer side of the middle layer frame 1, and a dynamic isolation curtain 4 arranged in the frame of the middle layer frame 1. Each dynamic isolation curtain 4 can be converted between a rolled state and a filled state. The inner heat preservation layer 2 comprises an inner layer frame 21 and a plurality of inner layer heat preservation plates 22. Each inner layer heat preservation plate 22 is rotatably connected with the inner layer frame 21, and each inner layer heat preservation plate 22 can be synchronously rotated. The outer heat insulation layer 3 comprises an outer layer frame 31 and a plurality of outer layer heat preservation plates 32. Each outer layer heat preservation plate 32 is rotatably connected with the outer layer frame 31, and each outer layer heat preservation plate 32 can be synchronously rotated. When the dynamic isolation curtain 4 is in the filled state, adjacent inner layer heat preservation plates 22 are kept in contact, adjacent outer layer heat preservation plates 32 are also kept in contact, and the two sides of the dynamic isolation curtain 4 are in contact with the inner heat preservation layer 2 and the outer heat insulation layer 3 respectively. When the dynamic isolation curtain 4 is in the rolled state, the dynamic isolation curtain 4 is hidden in the middle layer frame 1, there is a gap between adjacent inner layer heat preservation plates 22, and there is also a gap between adjacent outer layer heat preservation plates 32.

[0038] The heat insulation structure can be arranged at any position requiring heat preservation, constant temperature or heat insulation, and is used for isolating temperature transmission. In specific use, the heat insulation structure can be converted between an open state and a heat insulation state according to the rolling state and the filling state of the dynamic isolation curtain 4. When the dynamic isolation curtain 4 is in the filling state, the adjacent inner heat preservation plates 22 are kept in close contact, the adjacent outer heat preservation plates 32 are also kept in close contact, and the two sides of the dynamic isolation curtain 4 are in close contact with the heat preservation inner layer 2 and the heat insulation outer layer 3 respectively, so that the heat insulation can be realized through cooperation of the dynamic isolation curtain 4, the heat preservation inner layer 2 and the heat insulation outer layer 3. When the dynamic isolation curtain 4 is in the rolling state, the dynamic isolation curtain 4 hides in the middle layer frame 1, there are gaps between the adjacent inner heat preservation plates 22 and there are also gaps between the adjacent outer heat preservation plates 32, so that the heat can be exchanged between the inside and the outside of the heat insulation structure through the gaps between the inner heat preservation plates 22, the space of the middle layer frame 1 exposed after rolling of the dynamic isolation curtain 4 and the gaps between the outer heat preservation plates 32. Therefore, through arrangement of the heat insulation structure, the heat insulation and heat exchange conversion between the internal space and the external space of the heat insulation structure can be realized, so that the heat exchange can be effectively carried out or blocked according to actual needs, and then the working condition of the heat insulation structure can be effectively matched. Embodiment two

[0039] Please refer to Figures 1-8 The difference from the above embodiment is that the dynamic isolation curtain 4 comprises a rolling shell 41 and an isolation curtain core 42. The rolling shell 41 is internally provided with a rolling rotating shaft 43, one side of the rolling rotating shaft 43 is provided with a rolling torsional spring 44, the fixed end of the isolation curtain core 42 is fixed between the rolling rotating shaft 43, and the movable end of the isolation curtain core 42 is provided with a magnetic attraction pull rod 45. The rolling shell 41 is arranged on the inner side of the middle layer frame 1. Rolling track grooves 11 are arranged on the inner side of the middle layer frame 1 and located on both sides of the rolling shell 41. A magnetic attraction sealing groove 12 is arranged on the inner side of the middle layer frame 1 and located away from the rolling shell 41.

[0040] The two sides of the isolation curtain core 42 are respectively embedded in the two rolling track grooves 11, and the two ends of the magnetic attraction pull rod 45 are also respectively embedded in the two rolling track grooves 11. A rolling-off air rod 13 is arranged at one end of the rolling track groove 11 close to the rolling shell 41, and the movable end of the rolling-off air rod 13 is fixed between the magnetic attraction pull rod 45.

[0041] When the movable end of the unwinding air rod 13 is extended, the magnetic pull rod 45 can drive the movable end of the isolation curtain core 42 to overcome the elastic force of the winding torsion spring 44 and unwind from the winding shaft 43, and the two sides of the isolation curtain core 42 slide in the corresponding winding track groove 11 respectively. When the unwinding air rod 13 is extended to the longest state, the magnetic pull rod 45 extends into the magnetic sealing groove 12, and the magnetic pull rod 45 is magnetically fixed to the magnetic sealing groove 12; when the movable end of the unwinding air rod 13 is shortened, under the action of the elastic force of the winding torsion spring 44, the isolation curtain core 42 can be rewound on the winding shaft 43.

[0042] Several filled isolation bags 46 are respectively provided on both sides of the isolation curtain core 42, and an aerogel storage tank and an aerogel delivery pump are also provided inside the winding shell 41.

[0043] When in use, the magnetic pull rod 45 drives the movable end of the isolation curtain core 42 to overcome the elastic force of the winding torsion spring 44 and unwind from the winding shaft 43, and the two sides of the isolation curtain core 42 slide in the corresponding winding track groove 11 respectively. When the unwinding air rod 13 is extended to its longest state, the magnetic pull rod 45 extends into the magnetic sealing groove 12, and the magnetic pull rod 45 and the magnetic sealing groove 12 are magnetically fixed, so that the magnetic pull rod 45 and the magnetic sealing groove 12 are sealed, and the two sides of the isolation curtain core 42 are sealed with the corresponding winding track groove 11. The aerogel delivery pump can deliver and fill aerogel particles from the aerogel storage tank to each filling isolation bag 46 (the filling isolation bag 46 is an elastic structure), and the aerogel particles can enhance the temperature insulation ability of the two sides of the isolation curtain core 42 in each filling isolation bag 46, and then the cooperation of each filling isolation bag 46 and the isolation curtain core 42 can effectively achieve the purpose of heat insulation.

[0044] Before the movable end of the unwinding air rod 13 is shortened, the aerogel particles can be transported from each filled isolation bag 46 to the aerogel storage tank through the gel delivery pump, and the aerogel particles can be recovered, and each filled isolation bag 46 can be restored to the minimum state. Then, when the movable end of the unwinding air rod 13 is shortened, under the elastic force of the winding torsion spring 44, the isolation curtain core 42 can drive each filled isolation bag 46 in the minimum state on both sides to be rewound on the winding shaft 43, and the middle frame 1 can be opened, so that heat can pass through the vacant area of ​​the middle frame 1 and heat exchange can be carried out.
