Cold accumulation plate and cold accumulation method thereof

Abstract

The invention discloses a cold accumulation plate and a cold accumulation method thereof. A plurality of cold accumulation strips are arranged inside the cold accumulation plate from top to bottom in parallel. Gaps are reserved between the adjacent cold accumulation strips, the head of one gap is communicated with the tail of the adjacent gap, and refrigerating medium flowing channels are formed by the gaps inside the cold accumulation plate. The cold accumulation strips are internally provided with a cold accumulation agent cavity for containing a cold accumulation agent, and the cold accumulation plate is provided with an inlet and an outlet both of which are communicated with the refrigerating medium flowing channels. A refrigerating unit is started to enable a refrigerating medium to enter the refrigerating medium flowing channels inside the cold accumulation plate from the inlet, heat exchanging is carried out between the refrigerating medium and the cold accumulation strips in the process that the refrigerating medium flows inside the refrigerating medium flowing channels, the refrigerating medium flows out of the outlet to flow back to the refrigerating unit after heat exchanging, and circulation is finished. The refrigerating capacity for refrigerating is stored inside the cold accumulation agent inside the cold accumulation strips on which heat exchanging is carried out.

Description

technical field [0001] The patent of the present invention relates to a cold storage plate, especially a cold storage plate applied to refrigerated transport vehicles, refrigerated railway wagons and refrigerated containers. Background technique [0002] At present, cold storage refrigerated transportation is a refrigerated transportation technology with obvious advantages. It can not only fully guarantee the continuity and temperature stability of refrigerated transportation, but also ensure the transportation quality of frozen and refrigerated goods. It has the advantages of energy saving, environmental protection and low operating cost. The existing cold storage type refrigerated transport equipment mainly relies on sealed cold storage plates or cold storage strips to cool down to maintain low temperature. However, its disadvantage is that it requires a complex refrigeration system to charge the cold plate with refrigerant, and the charging time is long, usually 8-12 hou...

Problems solved by technology

However, its disadvantage is that it requires a complex refrigeration system to charge the cold plate with refrigerant, and the cooling time is long, usually 8-12 hours

Moreover, if the cold storage strips or refrigeration pipes are not well packaged, the cold storage agent or refrigerant will leak, which will cause pollution to the cargo.
