Description

A kind of long-acting cold insulated cabinet

Technical field

The utility model relates to technique of refrigeration fields, and in particular to a kind of long-acting cold insulated cabinet.

Background technique

Cold Chain Logistics refer to refrigerating based food production, storage transport, sale, to consumption before links in begin Eventually under defined low temperature environment, to guarantee food quality, a systematic engineering of business of food loss is reduced, Cold Chain Logistics are fitted It include agricultural product, food, food and drink raw material etc. with range, cold insulated cabinet is the equipment that product is commonly stored in Cold Chain Logistics, existing Cold insulated cabinet be usually to place to release cold part in the cabinet for being equipped with insulated side walls, guarantee the low temperature in cold insulated cabinet.Existing cold insulation Case releases cold part due to often replacing, and operation is relatively complicated, and waste of resource.In addition, cold insulated cabinet in order to guarantee cooling capacity will not loss, Therefore it cannot often open, therefore can not also know the temperature conditions in cold insulated cabinet.

Utility model content

The purpose of this utility model is exactly to provide a kind of service life to overcome the problems of the above-mentioned prior art Longer long-acting cold insulated cabinet.

The purpose of this utility model can be achieved through the following technical solutions: a kind of long-acting cold insulated cabinet, the cold insulation luggage Cabinet and case lid to be opened/closed are included, the cabinet includes shell, by the fixed liner inside the shell of more support frames, described Water tank, buffer layer and heat insulation layer are successively arranged between shell and liner, the water tank, buffer layer and heat insulation layer are wrapped in liner Outside side wall and bottom, the water tank are closed case, and inside filling releases cold medium, is equipped with insulating layer in the case lid.This hair It is bright that cold medium sealing will be released by setting airtight water tank, make to release cold medium cold-storage by freezing using preceding, in use, by object Product are placed in liner, cover case lid, and article is persistently placed in low temperature environment.

Preferably, the shell and liner are stainless steel material.

Preferably, the water tank is flexible plastic material, and the cold medium of releasing is water.Since releasing of filling in water tank is cold Medium is water, so water is cooled, the volume that freezes becomes larger, and flexible plastic material is used, it is possible to prevente effectively from water tank is bursting at the collision.

Tank top is equipped with water filling port.

Preferably, the buffer layer is aperture flexible foam, which has preferable elasticity, and volume becomes when water freezing Greatly, water tank is compressed outwardly against the buffer layer, buffer layer, and as ice gradually melts, water tank is gradually tapered up, and buffer layer is also gradually It resiles.In above process, the outer wall of water tank can be fitted closely with buffer layer always, since aperture flexible foam also has Good insulation effect, thus can guarantee water tank cooling capacity will not loss it is too fast.

Preferably, the insulating layer in the heat insulation layer and case lid is closed pore hard polyurethane foams.

Preferably, the hasp being mutually matched is equipped at the top of the case lid sidewall bottom and side wall of outer shell.

Preferably, the liner inner wall is fixed with temperature sensor, and the outer shell outer wall is equipped with and temperature sensor The display of connection.User can be by the temperature in display monitoring incubator, in incubator, especially in liner When temperature is greater than some value, article can be replaced into incubator, which carries out cold-storage.

Compared with prior art, the beneficial effects of the utility model are embodied in following several respects:

1. lossless consumable component, maintenance cost are low.

2. cold insulated cabinet design fully considers ice water states of matter difference, increase buffer layer, structure is more stable and reliable.

3. heat insulation layer uses polyurethane material, excellent heat insulating performance, cold insulation effect is more efficient.

4. heat insulation layer and buffer layer are ep-type material, production process is to ozone layer without destruction.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model.

Wherein, 1 is handle, and 2 be cold insulation case lid, and 3 be hasp, and 4 be support frame, and 5 be liner, and 6 be water tank, and 7 be buffer layer, 8 be heat insulation layer, and 9 be shell, and 10 be water filling port, and 11 be temperature sensor, and 12 be display.
