The cold accumulation device 2 comprises a heat exchanger, and the cooling medium obtains cold energy through the heat exchanger. The heat exchanger mode is adopted as the cold accumulation device 2, the temperature and the flowing condition of the cooling medium can be controlled according to the use requirement, and the cold quantity is conveniently stored. Wherein the cooling medium preferably adopts glycol solution, and has high cold storage effect.
Preferably, the ice box 23 is arranged in the heat exchanger, and can absorb excessive cold energy and provide cold energy for the surrounding environment by utilizing the characteristic of large specific heat capacity of water.
In order to facilitate the cooling medium to obtain more cold energy in the heat exchanger, a cold fluid channel in the heat exchanger is set as a single flow path formed by connecting a plurality of groups of U-shaped pipes in series. Two or more paths may be provided. And the flow channel of the cooling medium in the heat exchanger is provided with a plurality of guide plates 24 which are arranged in a staggered way, so that the cooling medium is reversed for many times in the heat exchanger and exchanges heat with cold fluid to obtain more cold energy.
The specific structure is an internal three-dimensional structure as shown in fig. 3, the flow direction channel of the cooling medium is an S-shaped channel, and the cold fluid channel is arranged in the S-shaped channel. The mode of the same-direction convection heat exchange is adopted, namely the flow direction of the cooling medium is the same as that of the cold fluid; alternatively, the efficiency of reverse heat exchange may be somewhat higher in theory, and for convenience of illustration, only the cocurrent flow path is shown.
The cooling medium is guided by the guide plate 24 to flow out of the heat exchanger after being bent for multiple times. The ice box 23 can be fixed on the guide plate 24, water is arranged in the ice box, and the ice box stores cold energy through freezing (phase change). The ice bank 23 can release cold to the cooling medium without the cold fluid providing cold.
The refrigerating box 1 is connected with the cold accumulation device 2 through the quick connector 11, so that the refrigerating box and the cold accumulation device are conveniently connected and disconnected, the action is simple, and time and labor are saved.
The cold accumulation device 2 comprises a driving pump for driving the cooling medium to flow, such as a peristaltic pump 21, and the peristaltic pump 21 has the advantages of good sealing performance, no pollution, high precision and convenience for better controlling the stable flow of the cooling medium.

The condenser 32 is on the back of the refrigerator as in a conventional refrigerator. The U-shaped pipe is also in a form of two inlets and two outlets. A three-in three-out flow path may be used. Theoretically speaking, when the branches are two to three, the heat exchange efficiency is good.
The evaporator 34 exchanges heat with the cooling medium through a heat exchanger to store the cooling energy in the cooling medium. Excess cold, may be stored in the ice bin 23, which is water in the ice bin 23.
When the refrigerator is used, the difference between peak and valley electricity is utilized to realize the refrigeration and cold accumulation of valley electricity, and when the peak electricity is used, the refrigeration is stopped, the peristaltic pump 21 is started, and the cooling medium is driven to slowly flow to each refrigerating chamber, freezing chamber and movable storage chamber. The temperature in the holding compartment is reduced by the release of cold. The rotation speed of the peristaltic pump 21 is adjustable, and the opening degree of the electric valve 4 can be controlled to maintain the temperature in the cabin by controlling the flow rate of the cooling medium.
In the product, the refrigerating box 1 and the cold accumulation device 2 are connected by using the quick connector 11, and certain cold quantity can be stored by using the cooling medium, so long as the required temperature of the refrigerating box 1 is set in advance. After the temperature is reached, the quick connector 11 is detached, and the hasp is opened, so that the electric heating furnace can be taken away, and the electric heating furnace is simple and convenient and does not need to use electric energy. And the heat preservation effect of the shell of the refrigerator 1 can be used as a movable cold source within a certain time.
When the movable refrigerating box 1 is particularly disassembled and taken, the corresponding electric valve 4 is closed through the controller, so that the outlet of the secondary refrigerant in the movable cabin is cut off, and then the liquid inlet pipe is closed, and the U pipe in the refrigerating box 1 is ensured to be filled with the cooling medium. When the mobile refrigerator 1 is returned to the refrigerator, the quick connector 11 is completely connected, and the return is input on the control interface, and the program control electric valve 4 is opened.
