Cold chain unit distribution box with independent cold storage space

Abstract

The invention discloses a cold chain unit distribution box with independent cold storage space. The cold chain unit distribution box comprises a machine box body, and cold storage space arranged in the machine box body; a cold storage device is arranged in the cold storage space; and an evaporator with a fan is arranged in the machine box body. The cold chain unit distribution box further comprises a compressor connected to the cold storage device and an outlet end of the evaporator with the fan, and a condenser connected to an outlet end of the compressor; and a refrigerant outlet end of thecondenser is connected to an expansion valve. The cold chain unit distribution box can preferably guarantee the temperature management of goods space, prevents the risk of no temperature control of cold chain goods by failures of an air cooler system, preferably retains a cooling plate to achieve more exquisite capacity of temperature difference control and temperature maintenance, prevents the problem of higher temperature difference in the temperature control process due to refrigeration and temperature maintenance always by the air cooler, and can meet the distribution demands with more exquisite temperature requirements.

Description

technical field [0001] The invention belongs to the technical field of cold chain distribution, and in particular relates to a cold chain unit distribution box with an independent cold storage space. Background technique [0002] Cold chain transportation requires to maintain a low temperature state during medium and long-distance transportation and short-distance distribution. It mainly involves low-temperature transportation tools such as railway refrigerated vehicles, refrigerated vehicles, refrigerated ships, and refrigerated containers. During refrigerated transportation, the temperature rises or the temperature Large fluctuations are one of the main reasons for the decline in the quality of goods. Therefore, the means of transportation should have good thermal insulation performance. While maintaining the specified low temperature, it is also necessary to maintain a stable temperature. Goods transported under certain temperature conditions must be precisely temperature...

Problems solved by technology

[0006] In order to solve the above-mentioned problems in the prior art, the object of the present invention is to provide a cold chain unit distribution box with an independent cold storage space, which better solves the existing cold chain unit distribution box, and there are cooling fans and cold storage plates at the same time When controlling the temperature of cold chain goods, when the cold storage plate needs to be cooled by a cooling fan, since the temperature of the cooling cold storage plate is much lower than the control temperature of the cold chain goods, it will cause freezing damage to the cold chain goods; The defect that the chain unit distribution box cannot maintain the temperature in the box for a long time after a power failure occurs
