A kind of ultra-low temperature preservation box

A technology of ultra-low temperature storage and box body, which is applied in the direction of thermal insulation containers, household refrigeration devices, lighting and heating equipment, etc., which can solve the problems of reduced thermal insulation effect, sagging of the door body, and increase of the weight of the door body, so as to reduce the probability of damage and reduce the risk of damage. The thickness of the small insulation layer reduces the effect of product quality

Problems solved by technology

[0004] 1. Since this equipment is used for ultra-low temperature refrigeration equipment, in order to effectively maintain the temperature, when the foam insulation material is used alone, the foam insulation material layer is generally made thicker, which highlights that the equipment is bulky and inflexible, and the weight of the door body increases. prone to door sagging
[0005] 2. When the foam insulation material is used alone, the insulation performance is poor, resulting in frequent startups of the refrigeration system and high power consumption
[0006] 3. Use foam insulation materials and vacuum insulation panels to form an insulation layer to maintain the internal temperature of the storage chamber. This technical solution can significantly improve the insulation performance, and the formed insulation layer is thinner. However, due to the use of vacuum insulation panels The outer membrane must not be damaged during the process, and the direct contact between the vacuum insulation panel and the metal wall will easily cause damage to the outer membrane, resulting in a greatly reduced or even invalid insulation effect, and the outer membrane damage of the vacuum insulation panel is not easy to be found

Embodiment Construction

[0026] A kind of ultra-low temperature preservation box of the present invention is described in detail below in conjunction with accompanying drawing:

[0027] like figure 1 and figure 2 As shown, the vertical ultra-low temperature storage box according to an embodiment of the present invention includes a box body assembly 8 , a door body assembly 9 , a cabin assembly 10 and a refrigeration system 12 .

[0028] The vertical ultra-low temperature storage box mainly sends the heat inside the storage box to the outside of the storage box through the refrigeration system 12 provided in the engine room assembly 10 and the evaporator 13 in the box assembly 8 to make the inside of the storage room reach a low temperature effect. In order to maintain the low-temperature cold capacity inside the preservation box, the box body assembly 8 and the door body assembly 9 play an insulating role to effectively reduce the overflow of cold capacity.

[0029] The box assembly 8 of the presen...

Abstract

The invention provides an ultra-low-temperature storage box which comprises a box shell, an inner container and a door assembly. The inner container is arranged in the box shell. The door assembly comprises a door shell and a lining. Heat preservation layer structures are arranged between the door shell and the lining and between the box shell and the inner container respectively. The heat preservation layer structures are formed by compounding foam heat insulation boards, vacuum heat insulation boards and foam heat preservation materials. Each ultra-low-temperature heat preservation layer structure with at least three layers of heat insulation heat preservation materials is adopted in the storage box, the thickness of each insulation layer is reduced, the mass of a product is decreased, the heat preservation effect is improved, and meanwhile, the vacuum heat insulation boards are protected.

Description

technical field [0001] The invention relates to the field of low-temperature storage equipment, in particular to an ultra-low temperature storage box. Background technique [0002] The ultra-low temperature preservation box is a kind of refrigeration equipment that reduces the temperature inside the preservation box to -86 degrees through the refrigeration system. Foam insulation and vacuum insulation panels. [0003] But there is following shortcoming in above-mentioned technical scheme: [0004] 1. Since this equipment is used for ultra-low temperature refrigeration equipment, in order to effectively maintain the temperature, when the foam insulation material is used alone, the foam insulation material layer is generally made thicker, which highlights that the equipment is bulky and inflexible, and the weight of the door body increases. It is easy to cause the door body to sag. [0005] 2. When the foam insulation material is used alone, the insulation performance is po...
