Description
Technical field
The utility model belongs to the low-temp. refrigerator technical field, more particularly relates to the improvement of the door sealing structure of low-temp. refrigerator.
Background technology
Low temperature, super low-temperature refrigerator refer generally to cryogenic temperature can reach-60 ℃ ,-86 ℃ even lower refrigerator.Be mainly used in the preservation of red blood cell, lymphocyte, skin, organ, DNA, embryo's seed, pollen etc. and the low-temperature test of special material.Its user mainly contains hospital, blood station, epidemic prevention station, institution of higher education, R﹠D institution etc.
Reach-60 ℃ ,-86 ℃ even lower because the temperature inside the box of low-temp. refrigerator is low, the cold conduction that the big temperature difference causes inside and outside loss of refrigeration capacity when picking and placeing article in order to prevent to open the door and the case, it is exactly crucial being equipped with highly exhausted cold door sealing structure.Therefore, the door sealing structure of existing low-temp. refrigerator still awaits improving.
The purpose of this utility model just is to overcome above-mentioned deficiency, provides a kind of exhausted cold performance higher, and the cold coefficient of conductivity and loss of refrigeration capacity are littler, the new improvement of the door sealing structure of the better low-temp. refrigerator of cold storage effect.
Summary of the invention
In order to achieve the above object, the utility model is made of the Men Timen envelope that is fixed on the doorframe door envelope on the doorframe and be fixed on the body.Adopt double density strip of paper used for sealing structure.One of Men Timen envelope or doorframe door envelope are that a kind of section is the elastomer strip of paper used for sealing of rectangle, and be another kind of then be that a kind of section is the elastomer strip of paper used for sealing that has the sphere of fixed edge.Close behind the door, the Men Timen envelope is pressed on the doorframe door and seals up and be out of shape.After the distortion, the elastomer strip of paper used for sealing hard-pressed bale of rectangle becomes one on the elastomer strip of paper used for sealing of sphere.Be close to tight pressure on the one hand, its seam has been deformed into the curve of intermediate projections on the other hand, has significantly reduced the loss of cold.
Section is that the elastomer strip of paper used for sealing and the section of rectangle is that the elastomer strip of paper used for sealing that has the sphere of fixed edge is made by rubber-plastics material.Rubber-plastics material is a polyurethane elaster.The exhausted cold coefficient height of polyurethane elaster, low temperature resistant ageing properties is good, and effect is best.
Doorframe adopts collapsible two anti-cold bridge construction.Have high outside and low outside two-layer table top on the doorframe, collapsible two anti-cold bridge construction is installed.The exhausted cold mould material of the plastics that on the two-layer table top section to be installed respectively be H shape, the shell steel plate of doorframe and inner bag steel plate insert two H respectively and mould in the water jacket of expecting exhausted cold mould material, and another steel plates that are bent into two foldings insert two H respectively and mould in the inside groove of expecting exhausted cold mould material.Section is to have one of the elastomer strip of paper used for sealing of sphere of fixed edge or elastomer strip of paper used for sealing that section is rectangle to be fixed on outer field H and to mould on exhausted cold mould material of material and the shell steel plate.Two H mould the exhausted cold mould material of material and play cold effect of opening circuit, and have improved cold storage effect of the present utility model to a greater extent.This collapsible two anti-cold bridge constructions link to each other inner bag with shell, both prevented that cold from passing through scattering and disappearing of cold bridge, have solved material breakage problem at low temperatures again, greatly reduce loss of refrigeration capacity.
Section is that the sphere of elastomer strip of paper used for sealing that has a sphere of fixed edge can be one or more.The sealing property of the strip of paper used for sealing of a plurality of spheries is better, because its curve is more tortuous, the exhausted cold performance after compressing is also just better.But can not be too many, should decide on the installation site.
The utility model be installed in doorframe and the door body around.One side of doorframe and door body has hinge, is convenient to open the door.Opposite side has a nose, is convenient to close the door.
Task of the present utility model comes to this and finishes.
The utility model provides a kind of exhausted cold performance higher, and the cold coefficient of conductivity and loss of refrigeration capacity are littler, the new improvement of the door sealing structure of the better low-temp. refrigerator of cold storage effect.It can be widely used in various common, low temperature, super low-temperature refrigerator and the refrigerator.
Description of drawings
Structural representation when Fig. 1 opens the door for the utility model.
Fig. 2 is a schematic diagram at closing time.
Shown in Figure 1, the utility model adopts double density strip of paper used for sealing structure.Constitute by the Men Timen envelope that is fixed on the doorframe door envelope on the doorframe 1 and be fixed on the body 2.The Men Timen envelope is that a kind of section is the elastomer strip of paper used for sealing 3 of rectangle, and doorframe door envelope is that a kind of section is the elastomer strip of paper used for sealing 4 that has the sphere of fixed edge.The two is made by rubber-plastics material.Effect was best when rubber-plastics material was polyurethane elaster.Adopt collapsible two anti-cold bridge construction on the doorframe 1.Have high outside and low outside two-layer table top 5 and 6 on the doorframe 1.The exhausted cold mould material 7 and 8 of the plastics that on the two-layer table top 5 and 6 section to be installed respectively be H shape.The shell steel plate 9 of doorframe 1 and inner bag steel plate 10 insert two H respectively and mould in the water jacket of expecting exhausted cold mould material 7 and 8.Another steel plate 11 that is bent into two foldings inserts two H respectively and moulds in the inside groove of expecting exhausted cold mould material 7 and 8.Section is that the elastomer strip of paper used for sealing 4 (doorframe door envelope) that has the sphere of fixed edge is fixed on outer field H and moulds on exhausted cold mould material 7 of material and the shell steel plate 9.
Shown in Figure 2, to close behind the door, the Men Timen envelope is pressed on the doorframe door and seals up and be out of shape.After the distortion, elastomer 3 hard-pressed bales of rectangle become one on the elastomer strip of paper used for sealing 4 of sphere, have significantly reduced the loss of cold.Fig. 1 and Fig. 2 are the horizontal cutaway top view of low-temp. refrigerator front portion.12 is hinge, and 13 is the door nose.
