Abstract
The utility model relates to a radiation protection screen component used for subzero refrigerators, which mainly aims to resolve problems that vapor is condensed at a joint of a top cover and a refrigerator body of a subzero refrigerator when air is cooled, and then the cover of the refrigerator can not be opened. The radiation protection screen component comprises a radiation protection screen cover plate and at least one radiation protection screen, circle centers of the radiation protection screen cover plate and the radiation protection screens are located on the same axial line, arranged in parallel at intervals and fixed integrally, and the radiation protection screen cover plate and the three radiation protection screens are fixed via screw stems and nuts and arranged in parallel at an interval ranging from 15mm to 25mm. The radiation protection screen component is arranged between an opening of an inner container of the subzero refrigerator body and the top cover of the refrigerator body, effectively shields heat radiation and heat conduction which are caused by large temperature difference inside and outside the refrigerator body, and avoids conditions that the cover of the refrigerator can not be opened because vapor condensation at the joint of the top cover and the refrigerator body of the subzero refrigerator when air is cooled so that the refrigerator cover can be opened easily.
Description
Affiliated technical field:
The utility model relates to the parts in the deep cooling refrigerator, is specifically related to a kind of protective shield of radiation assembly that is used for the deep cooling refrigerator, is convenient to the unlatching of case lid.The deep cooling refrigerator is mainly used in the midium or long term preservation of the various bioactivators in the fields such as biology, medical research, medical treatment are clinical, agriculture, animal husbandry.The utility model belongs to refrigeration and cryogenic engineering field.
Background technology:
Temperature in the deep cooling refrigerator body is-100～-180 ℃, with circumstance of temperature difference very big (about about 200 ℃), traditional deep cooling refrigerator case lid and casing interface very easily are frozen in and cause case lid to be difficult for being opened, main cause is that the casing internal-external temperature difference is very big, there are heat radiation and heat conduction, cause the steam in the outer hot-air of casing to meet the condensation knot and the case lid of not opening at case lid and casing interface.
Summary of the invention:
At above-mentioned problems of the prior art, the purpose of this utility model is to solve the cold problem that very easily causes top cover to be frozen by frosting and do not open of air chance that deep cooling refrigerator body top cover meets the envelope place, the utility model proposes a kind of protective shield of radiation assembly that is used for the deep cooling refrigerator for this reason, this assembly has good shielding heat radiation and heat conducting function, has guaranteed that deep cooling refrigerator case lid can open easily.
The utility model is the technical scheme that its purpose of realization is taked: a kind of protective shield of radiation assembly that is used for the deep cooling refrigerator comprises protective shield of radiation cover plate and at least one protective shield of radiation, the center of circle of described protective shield of radiation cover plate and protective shield of radiation is positioned on the same axis, and spaced and parallel is arranged and is fixed as one.
Described protective shield of radiation is three, fixes with screw rod and nut between protective shield of radiation cover plate and each the sheet protective shield of radiation, and parallel interval 15-25mm arranges successively.
Described protective shield of radiation cover plate is that diameter is that φ 200-240mm, thickness are the duralumin plate material of 2-4mm; Described protective shield of radiation diameter is φ 185-205mm, and thickness is the stainless steel disk of 0.4-0.6mm, and two-sided roughness is greater than 3.2.
Described screw rod and nut are stainless steel screw rod, the nut of three groups of M5, are the equilateral triangle symmetric arrangement and fix; Bail is equipped with in described protective shield of radiation cover plate center.
Heat radiation of the utility model maskable and heat conduction, it is placed between deep cooling refrigerator body inner bag opening part and the casing top cover, inside and outside big heat radiation that the temperature difference causes of casing and heat conduction have been shielded effectively, the situation that the case lid of having avoided casing top cover and casing interface to cause owing to air chance cold water vapour condenses can't be opened can be opened case lid easily.
The beneficial effects of the utility model: adopt this protective shield of radiation assembly to guarantee that the cold in the inside and outside big temperature difference condition lower box of casing is difficult for being transmitted to casing top cover place by radiation, thereby guaranteed that the casing top cover can not freeze in frosting, can open easily.
Description of drawings:
Below in conjunction with accompanying drawing and example the utility model is further specified:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the position view of the utility model in casing.
Among Fig. 1: 1, protective shield of radiation cover plate, 2, protective shield of radiation, 3, screw rod, 4, nut;
Among Fig. 2: 5, box liner, 6, the casing top cover, 7, the protective shield of radiation assembly, 8, the sterlin refrigerator refrigerating part.
The specific embodiment:
In Fig. 1, protective shield of radiation assembly of the present utility model is made up of the protective shield of radiation 2 of the thick stainless steel of the thick aluminium matter protective shield of radiation cover plate 1 of a slice φ 220 * 3mm of interval 20mm and three φ 195 * 0.5mm, with the screw rod 3 of M5 they is connected in series at interval therebetween and fixing with the nut 4 of M5.The thermal conductivity factor of stainless steel is low, and the two-sided roughness height (reaching 3.2) of protective shield of radiation has played good radiation protection simultaneously.Protective shield of radiation cover plate 1 and three protective shield of radiation 2 plate faces interval 20mm are arranged in parallel, and the center of circle is on same axis, and three groups of screw rods, nuts are the equilateral triangle symmetric arrangement to be fixed; Bail is equipped with in protective shield of radiation cover plate center, is convenient to mention.
The protective shield of radiation cover plate, the duralumin plate material had not only guaranteed merrily and lightheartedly but also had satisfied intensity and anticorrosion requirement.
Three protective shield of radiations not only have the characteristics of thermal conductivity factor low (14.7W/m. ℃), have played fine shielding heat radiation and heat conducting effect, also have etch-proof effect simultaneously.In actual fabrication, also can adopt a slice, the protective shield of radiation more than two or three, depend on the needs.
Fig. 2 is the location drawing of protective shield of radiation assembly in the deep cooling casing.Deep cooling refrigerator body among the figure is a round box that vacuumizes with the polyurethane foam composite adiabatic, internal capacity is 5L (diameter is φ 198mm), circular casing top cover 6 upwardly opens and closes, the protective shield of radiation assembly is placed in box liner 5 opening parts, close casing top cover 6 then, when the refrigeration machine cold head is lowered the temperature the process of freezing and being incubated in inner bag in, the protective shield of radiation assembly can stop radiant heat transfer effectively, when cryogenic temperature is minimum when reaching-161 ℃, casing top cover 6 still can be opened easily through experimental verification.
The utility model is arranged between deep cooling refrigerator body inner bag opening part and casing top cover, has so just suppressed the heat transmission of radiation and conduction pattern effectively, has guaranteed that promptly the cold in the casing is not is not scattered and disappeared, and the casing top cover is opened and also is easy to simultaneously.The utility model has played good shielding heat radiation and heat conducting effect, has guaranteed that deep cooling refrigerator case lid can open easily.
