Abstract
The utility model provides a cryogenic temperature refrigeratory which comprises a cabinet opening, a door body and sealing strip thereon. The utility model is characterized in that at least one axial slot in the front middle of the joint between the sealing strip and the cabinet opening or chest is formed on the door body. The joint of the cabinet opening and the sealing strip with slot on the front is a ridgy arc. The utility model has reasonable sealing structure, good joint between the sealing strip and the cabinet opening, therefor increasing the entire sealing performance of the cryogenic temperature refrigeratory, preventing the failure closing due to the hard touching between the door body and the cabinet opening, and reducing the cold loss caused by the heat conduction via the door.
Description
Technical field
The utility model belongs to the cryogenic refrigeration field, is to use temperature at-40 ℃～-86 ℃ super low-temperature refrigerator specifically.
Background technology
Existing-86 ℃ of super low-temperature refrigerators are used widely in fields such as medical science, biological products, electronic materials, are used to preserve red blood cell, leucocyte, skin, bone, bacterium, and the low temperature test of electronic device and special material.Sealing is the key that can low-temp. refrigerator the temperature inside the box reach designing requirement, also is assurance equipment stable operation and energy-conservation necessary simultaneously.The constant embrittlement of encapsulant requirement is hard when low-temp. refrigerator the temperature inside the box reaches-86 ℃, and conventional hermetically-sealed construction and sealing material can't meet the demands under low temperature environment like this.Double-layer sealing structure is mostly adopted in existing-86 ℃ of low-temp. refrigerator door bodies sealing, and sealing effectiveness is not ideal enough, and it is relatively poor at the solid sealing effectiveness of the temperature inside the box designing requirement situation lower seal material hardens that What is more.The poorly sealed operation hours lengthening of making shortens downtime, has increased meaningless equipment energy consumption, and the temperature inside the box uniformity reduces simultaneously.
Summary of the invention
The purpose of this utility model is to provide a kind of super low-temperature refrigerator at the deficiencies in the prior art, and its hermetically-sealed construction is reasonable, and sealing strip and cabinet mouth post, and strengthens the sealing of refrigerator, can avoid Men Tiyu cabinet mouth to contact the pass firmly and not call.
The technical solution of the utility model is: a kind of super low-temperature refrigerator, comprise the sealing strip on refrigerator box body and cabinet mouth, door body and the door body, and have a slit vertically in the middle of the front that it is characterized in that having at least a sealing strip to contact on the body with cabinet mouth or casing.
On the described casing cabinet mouth with apertured sealing strip contact site, front for the protuberance cambered surface.
Have the front that the sealing strip of raised line is set on the described door body, there is the groove that matches with the raised line of sealing strip front the casing cabinet oral area position that contacts with the sealing bar.
On the described door inner body surface three sealing strip square frames are set, are followed successively by interior sealing strip, middle sealing strip, external seal bar from inside to outside, the front is provided with the interior sealing strip that is of raised line.
Have a slit in the middle of the front that sealing strip contacts with the cabinet mouth in described vertically, the rear portion of middle sealing strip front connects two reinforcements.
Have a slit vertically in the middle of the contact-making surface of sealing strip and cabinet mouth in described, the left and right sides symmetry of interior sealing strip and cabinet mouth contact portion cross section is respectively S shape and Z-shaped.
The utility model compared with prior art has many advantages and good effect:
The utility model adopts three layers of special hermetically-sealed construction, and interior gasket structure distortion is big, and the front is provided with raised line, can match with the groove of casing cabinet mouth corresponding position, posts good airproof performance with the cabinet mouth; In sealing strip front apertured structure can on make in the protuberance cambered surface of cabinet mouth corresponding position directly reaches in the sealing strip chamber good airproof performance; External seal bar and the adhesive of doorframe magnetic force make inside and outside isolated, further strengthen the sealing heat-proof quality.The slit is all arranged in the middle of the contact-making surface because of interior sealing strip and middle sealing strip and cabinet mouth, having avoided Men Tiyu cabinet mouth to contact the pass does not firmly call, strengthened the sealing of whole low-temp. refrigerator, and reduce inside and outside heat transfer temperature difference successively, reduced the loss of refrigeration capacity that causes by the Men Youre conduction, in satisfying case, further reduce power consumption under the design temperature condition, and improve the uniformity of the temperature inside the box.
Description of drawings
Fig. 1 is the front view of the utility model super low-temperature refrigerator;
Fig. 2 is that the A-A of Fig. 1 is to profile;
Fig. 3 is the partial enlarged drawing of B portion among Fig. 2.
The specific embodiment
Referring to Fig. 1-Fig. 3, a kind of embodiment of ultralow temperature vertical freezer comprises the sealing strip 1,2,3 on cabinet mouth 6, door body 7 and the door body of installing on the refrigerator box body 47.On door body 7 inner faces three square frame shape sealing strips 1,2,3 are set, sealing strip 3, middle sealing strip 2, external seal bar 1 in being followed successively by from inside to outside, middle sealing strip 2 materials are low temperature resistant silicon rubber, have a slit vertically in the middle of the front that middle sealing strip 2 contacts with cabinet mouth 6, middle sealing strip 2 is connected two inclined plane reinforcements with the rear portion, front of cabinet mouth 6 contacts.Casing cabinet mouth 6 is the cambered surface 5 of protuberance with the contact site of middle sealing strip 2.
Have a slit in the middle of the front that interior sealing strip 3 contacts with cabinet mouth 6 vertically, the left and right sides symmetry of interior sealing strip 3 and cabinet mouth 6 contact portion cross sections is respectively S shape and Z-shaped structure.Interior sealing strip 3 fronts are provided with raised line, with position on the cabinet mouth 6 that interior sealing strip 3 contacts for protuberance little cambered surface (or plane), the groove that matches with the raised line of interior sealing strip 3 fronts is arranged on the plane on little cambered surface and both sides.
The low temperature resistant silicon rubber of interior sealing strip 3 material selections does not become fragile in the time of-86 ℃, and keeps certain flexibility.Interior sealing strip 3 all has a certain amount of strain and cabinet mouth 6 to fit under pressure, and interior sealing strip 3 cross sections are open structure, and exhaust velocity is not slow in the time of the air cavity compression can not occurring, deflection is little, close the phenomenon of not calling.In sealing strip 2 fit with the cambered surface 5 of cabinet mouth protuberance because middle sealing strip 2 contacts with protuberance cambered surface 5, not only play sealing function, and cambered surface 5 can not occur swelling and directly withstand on middle sealing strip 2 crucial points, cause closing the phenomenon of not calling.External seal bar 1 is all selected low temperature resistant PVC for use with the gate seal material.External seal bar 1 strain and doorframe under the magnetic force adhesive are fitted and are played sealing function, further strengthen the sealing heat-proof quality.Three-layer sealed structure acting in conjunction had both been avoided closing and had not been called, and had guaranteed effective seal again.
Certainly; above-mentioned explanation is not to be to restriction of the present utility model; the utility model also is not limited to above-mentioned ultralow temperature cabinet and also can be used for low-temp. refrigerator or common refrigerator; those skilled in the art; in essential scope of the present utility model; the variation of having done, remodeling, interpolation or replacement also should belong to protection domain of the present utility model.
