Problems solved by technology
[0005] The disadvantage of the above patent is that the cold storage box produced by this technology only has a filling port and no exhaust port. When filling the liquid cold storage agent, it is easy to produce air resistance, which increases the difficulty of filling; grooves are arranged on the opposite sides of the box body , although it can increase the effective heat transfer surface area of the box, it will have the disadvantage of poor box strength

The invention discloses a method for manufacturing an attapulgite gel cold storage box, and the key points of the technical scheme are as follows: the attapulgite gel cold storage box is a rectangular casing body, a feeding hole and an external cover of the feeding hole are formed at the upper left part of the attapulgite gel cold storage box, an exhaust hole and an internal cover of the exhaust hole are formed at the upper right part of the attapulgite gel cold storage box, a horizontal groove and a vertical groove are designed on the front surface and the back surface of the attapulgite gel cold storage box, an attapulgite gel cold storage agent is added into the attapulgite gel cold storage box from the feeding hole, and an expansion space is reserved at the upper right part in the attapulgite gel cold storage box. The cold storage speed of the attapulgite gel cold storage box is fast, the internal temperature of the cold storage box can be reduced to below minus 25 DEG C, and the attapulgite gel cold storage box can be maintained at minus 10-0 DEG C for a long time in a refrigerator after cold storage. The attapulgite gel cold storage box can repeatedly carry out the cold storage and keep a certain cooling temperature, and the installation is convenient. The method for manufacturing the attapulgite gel cold storage box is applicable to fabricating the cold storage boxes, cold storage plates and cold storage cabinets.
Description
technical field [0001] The invention relates to a cold storage box, in particular to a method for making an attapulgite gel cold storage box. Background technique [0002] There are many types of cold accumulators used to store cold storage agents, and they are constantly being updated, including: refrigerator cold accumulators, refrigerator or freezer cold accumulators, portable refrigerators, cold storage bags, energy-saving cold storage refrigerator boxes, cold storage air conditioners and cold storage box etc. [0003] Most of the existing cold storage devices use cold storage boxes for cold storage pretreatment, and the cold storage boxes are added to the cold storage for use after cold storage. [0004] Chinese patent authorization announcement number CN2789165, the date of authorization announcement is June 21, 2006, and the name is "a kind of cold storage box". groove (3). The utility model is provided with grooves on opposite sides of the box body, which increases...
