Portable refrigerating heat-preservation box and control method thereof

Abstract

The invention discloses a portable refrigerating heat-preservation box and a control method thereof. The portable refrigerating heat-preservation box comprises an electric control plate, a semiconductor refrigerating piece, a water pump, a storage battery, a heat-preservation water tank, a first heat-preservation box body and a second heat-preservation box body; and the heat-preservation water tank comprises a heat conduction liner and a heat-preservation layer, the heat conduction liner is covered with the heat-preservation layer, the cold end face of the semiconductor refrigerating piece is attached to the heat conduction liner, the water pump communicates with the heat conduction liner, a first water cooling module is arranged in the first heat-preservation box body, a second water cooling module is arranged in the second heat-preservation box body, the water pump is connected with a water inlet of the first water cooling module and a water inlet of the second water cooling module, and the first water cooling module and the second water cooling module communicate with the heat conduction liner. The purpose that heat-preservation performance and refrigerated storage temperature uniformity of the portable refrigerating heat-preservation box are improved is achieved, thus continuous refrigerating time is prolonged, and service reliability is improved.

Description

technical field [0001] The invention relates to refrigeration equipment, in particular to a portable refrigeration insulation box and a control method thereof. Background technique [0002] Portable refrigeration equipment is widely used because it is easy to carry out. The portable refrigeration equipment in the prior art usually includes an incubator. Due to the limitation of power supply in an environment without external power supply, the incubator usually adopts a direct cooling refrigeration method. , for example: using dry ice, or configuring refrigeration components driven by batteries for refrigeration. However, due to the influence of the cooling method, the temperature at the position close to the dry ice or the refrigeration component is often lower, while the temperature at the farther position is higher, which makes the temperature distribution in the incubator uneven. How to design an incubator with high thermal insulation performance, long continuous refrige...
