Abstract

The invention discloses a vaccine cold chain heat insulation box adapted to military, and the heat insulation box provides guarantees for articles which need to be refrigerated such as vaccine when the military is under peacetime and war time conditions or performs rescue and relief work. The military cold chain heat insulation box is one-time formed by adopting a unique rotational moulding technology, an insulation layer adopts a polyurethane foaming filling technology, and the heat insulation performance is good. An ice raft fixing frame is assembled to enable the function and space selecting and using to be more flexible. Two-dimension code or one-dimension code bar identification is made on a display screen on the front face of a box body, and an identification card is installed on the back face of the box body. The weight is designed to be smaller than or equal to 12.6 kg. Ice rafts are adopted to achieve refrigeration under the 35 DEG C external environment, and it can be guaranteed that the temperature in the box ranges from 2 DEG C to 8 DEG C in 48-72 hours. The normal service life of the box body is more than 12 years. A pull rod is assembled outside the box body so that the box can be conveniently carried. Air guide channels are reserved in the box body to enable the temperature in the box to be more uniform. An anti-electromagnetic radiation package bag is adopted to protect the vaccine and the like against electromagnetic pollution.

Description

Military cold chain heat insulation box

Technical field

Patent of the present invention belongs to the preservation of vaccine cold chain and technical field of transportation, particularly relates to a kind of cold chain heat insulation box.

Background technology

The vaccine overwhelming majority needs 2 DEG C ~ 8 DEG C storages.But in vaccine storage and transport process, the problems such as Basic characteristics invalidated, temp. controlling alarm are not complete, vaccine is frozen all have report.This just requires the condition that the reception of vaccine, accumulating and end use, and needs scientific, systematization further, normalisation and practical.The crushing resistance of domestic and international similar insulation can, crash resistance all do not reach my national military standard standard, and are generally 2 ~ 3 years service life.Do not meet the cold chain heat insulation box of army's field operations or disaster assistance requirement at present.

Summary of the invention

The problem to be solved in the present invention needs chilled goods to provide safeguard for army puts down vaccine etc. under war condition.

A kind of cold chain heat insulation box, adopts unique rotational molding technique, one-shot forming, and heat-insulation layer adopts polyurethane foam filling process, and heat-proof quality is excellent.Its coefficient of thermal conductivity is only 0.016--0.024W/m.k, is one of good heat preserving and insulating material of best performance.Equipped ice raft fixed mount, makes function, space selects more flexible.Above the read-out of casing front, make Quick Response Code or one-dimension code bar mark, box back surface is equipped with tag card.Also can as required, shift one's position arbitrarily.Size conforms GJB182A-2000.Outside dimension: 640mm × 440mm × 520mm, adds inside dimension: 558mm × 260mm × 353mm after ice raft, effective internal volume: 51.21 liters, design weight≤12.6kg.Under extraneous 35 DEG C of environment, adopt ice raft to freeze, ensure that in 48-72 hour, the temperature inside the box is at 2 DEG C-8 DEG C.The normal service life of casing is more than 12 years.The exterior pull bar of casing, is easy to carry.Reserved air conducting groove in casing, make the temperature inside the box evenly.Employing anti-electromagnetic radiation packaging bag guarantee vaccines etc. are from electromagnetic pollution.Under extraneous 35 DEG C of environment, ice raft is adopted to freeze ensure the temperature inside the box to ensure at 2 DEG C-8 DEG C in 48 hours.Compatible with environment: 1. ambient temperature :-20 DEG C, under+35 DEG C of conditions, the temperature inside the box meets the storage traffic condition of 2 DEG C ~ 8 DEG C, temperature retention time 48 ~ 72 hours; 2. relative humidity: 20% ~ 98% (25 DEG C); 3. leakage performance: outer case leak tightness meets the regulation that method in GJB2711-1996 carries out testing, and meets IP55 requirement; 4. high-temperature behavior, low-temperature properties: meet GJB150.9-1986, GJB150.4-1986, GJB150.4-1986 regulation.Mechanical property: 1. anti-dropping capability: meet GJB2711.1-96 requirement, and meet low temperature and fall requirement; 2. compressive property: meet GJB2711.12-96 requirement; 3. shock resistance: meet GJB2711.9.11-96 requirement; 4. stacking performance: meet GJB2711.13-96 requirement.

The beneficial effect of patent of the present invention is: heat-insulation layer heat-proof quality is excellent, the normal service life of casing is more than 12 years, the exterior pull bar of casing is easy to carry, in casing reserved air conducting groove make the temperature inside the box evenly, under extraneous 35 DEG C of environment, adopt ice raft to freeze ensure the temperature inside the box to ensure at 2 DEG C-8 DEG C in 48 hours.

Comprising 1. case lids, 2. ice raft, 3. carrying handle, 4. air conducting groove, 5. hasp, 6. casing, 7. pull bar, 8. drain gutter, 9. control panel, 10. acoustic-optic alarm.

Detailed description of the invention

As shown in Figure 1, after opening box covers, vaccine is put into case.Press and control panel enables button, send application to backstage and enable message, start storage temperature data in storage card simultaneously, and report temperature data by communication module.Temperature data in cold chain heat insulation box in the display of casing outside, and can be derived as requested.Beginning in case is loaded until be transported to destination, case inner sensor real-time collecting temperature data, battery status data etc. at vaccine.Exceed standard as occurred, the situation such as power-off, cold chain heat insulation box itself can carry out sound and light alarm, and automatically sends note to relevant responsible official.
