Movable cabinet freezer for cold chain

Abstract

The invention discloses a movable cabinet freezer for a cold chain. The movable cabinet freezer comprises an insulation heat-preservation box body, a compressor refrigerating module; a cold source supply device, a temperature sensing and transmission module and an electric power module, wherein the insulation heat-preservation box body is provided with a storage chamber for holding articles; the compressor refrigerating module is used for providing the refrigerating capacity; the cold source supply device is arranged on the periphery of the storage chamber and used for alleviating the temperature variation of the storage chamber within a preset time, and when the compressor refrigerating module is not operated, the current temperature of the storage chamber can be maintained as far as possible; the temperature sensing and transmission module is used for sensing the current temperature of the storage chamber and transmitting a temperature signal; the electric power module is used for supplying the electric power; a processor of a control module is used for receiving and processing the temperature signal, a temperature management module is used for calculating the electric power needed for reducing the temperature of the storage chamber to the preset temperature range according to the current temperature of the storage chamber and the residual electric power of the electric power module, then the electric power module supplies the electric quantity corresponding to the electric power to the compressor refrigerating module, and the compressor refrigerating module is started.

Description

technical field [0001] The invention relates to a mobile freezer, in particular to a mobile freezer used in cold chains. Background technique [0002] There are known portable compressor refrigerators capable of providing cooling capacity, however, the design of known portable compressor refrigerators has not considered how to integrate with the freezer chain. On the other hand, most of the power sources of known portable compressor refrigerators are rechargeable storage batteries, such as storage batteries for vehicles, which are difficult to provide long-term power. Furthermore, when the storage battery has no power, the charging problem will also fail to meet the strict requirements of the cold chain. [0003] Known US Patent No. 7,271,719B2 "RFID SYSTEM FRO MONITORING FOOD HYGIENE", which teaches how to use RFID tag technology to monitor the hygiene of transported food. [0004] Known U.S. Patent No. 6,326,892B1 "is used for supervising cold chain and is used for the m...
