Self-contained refrigeration medium temperature controllable cargo cold chain transport ice box

Abstract

The invention discloses a temperature-controllable cargo cold chain transportation ice box with a refrigeration medium. The temperature-controllable cargo cold chain transportation ice box comprises a refrigeration device, a refrigeration chamber and a box body, and is characterized in that a heat preservation layer is arranged in a heat preservation shell body of the refrigeration device; a medium flow-out pipe is connected below an alcohol dry ice medium container and is connected with a cold and heat exchange copper pipe by connecting a valve and a relay; the valve, the relay and the cold and heat exchange copper pipe are connected with a medium recycling container through a medium backflow pipe; a CO2 discharging microhole is formed in the medium recycling container; the cold and heat exchange copper pipe is arranged below an isolation layer at the bottom of the heat preservation shell of the refrigeration device; and the valve and the relay are connected with each other through a singlechip arranged in a temperature controller in a control manner. According to the temperature-controllable cargo cold chain transportation ice box, a cold medium made of alcohol replaces a compressible refrigerant of a refrigerator; a heavy motor and a heavy compressor are eliminated; the temperature-controllable cargo cold chain transportation ice box is light in weight and can automatically control the temperature; the refrigeration time period is prolonged; a cooling medium can be added during refrigeration; and the temperature-controllable cargo cold chain transportation ice box can be used for a relatively long time.

Description

technical field [0001] The invention relates to a cold chain transport storage device, in particular to an ice box for cold chain transport of goods with its own refrigeration medium temperature controllable. Background technique [0002] In the cold chain transportation of goods, packaging boxes that are insulated and self-refrigerated are required. In medical work, there are also some medicines that need to be stored at low temperature and must be displaced with people’s actions, or remote delivery of special substances (such as human transplanted organs). Temperature-controlled thermal box. However, the refrigeration machinery and electrical control settings designed and manufactured according to the working mechanism of traditional refrigerators will inevitably make the refrigerators bloated, heavy, and difficult to move. Therefore, the refrigerator formula ice box that people need can only be a kind of fantasy. In the case of no way, once you need to carry medicines ...
