[0031] The present invention is described in detail below in conjunction with the accompanying drawings:

[0032] Embodiment 1, combination Figures 1 to 5A complete vertical refrigeration display cabinet with a heat dissipation device includes a foam cabinet 1, a refrigeration system 2, a heat dissipation device 3 and a controller. The foam cabinet 1 has a refrigeration chamber 11 on the inside, and the front side of the refrigeration chamber 11 is an open structure. The four corners of the bottom of the foam cabinet 1 are respectively provided with a support leg 12. The four support legs 12 can be adjusted in height to support and stabilize the foam cabinet 1. The controller is installed on the top front side of the foam cabinet 1, and the controller already available in the prior art is used to realize automatic control of various electrical components of the refrigeration display cabinet.

[0033] The foam cabinet 1 includes an outer shell 14 and side panels. The interior of the outer shell 14 is provided with a bottom plate 15, a back plate 13 and a top plate 16. A foam layer is fixed to the inner wall of the outer shell 14, and the heat insulation of the foam layer is used to keep the interior of the foam cabinet 1 warm. The bottom plate 15 and the top plate 16 are fixedly installed at the lower and upper parts of the outer shell 14 respectively through sheet metal connectors. The back plate 13 is vertically fixedly installed at the rear of the outer shell through sheet metal columns. The upper and lower ends of the back plate 13 are respectively integrated with the rear ends of the top plate 16 and the bottom plate 15. There are two side panels, which are vertically arranged on the left and right sides of the outer shell 14 respectively. The side panels are fixedly connected to the sides of the outer shell 14. The bottom plate 15, the back plate 13, the top plate 16 and the two side panels cooperate to form the cold storage room 11.

[0034] The foam cabinet 1 has a circulating air cavity inside, and the circulating air cavity is located between the bottom plate 15, the back plate 13, the top plate 16 and the foam layer. The circulating air cavity is connected end to end by a bottom air duct 41, a back air duct 42 and a top air duct 43, wherein the bottom air duct 41 is located below the refrigerating chamber 11, the back air duct 42 is located at the rear side of the refrigerating chamber 11, and the top air duct 43 is located above the refrigerating chamber 11.

[0035] The air outlet of the circulating air chamber is located at the top of the refrigerating chamber 11, and the return air outlet is located at the bottom of the refrigerating chamber 11. Specifically, the air outlet is located at the front side of the top plate 16, and a honeycomb mesh 44 is arranged on the air outlet. The return air outlet is located at the front side of the bottom plate 15, and a return air grille 45 is arranged on the return air outlet. The circulating air chamber forms a circulation loop with the refrigerating chamber 11 through the air outlet and the return air outlet. In the working state, the cold air of the circulating air chamber is blown into the refrigerating chamber 11 through the top air duct 43 and the honeycomb mesh 44, moves downward inside the refrigerating chamber 11, and then returns to the bottom air duct 41 through the return air grille 45.

[0036] A plurality of shelves 5 are arranged at the rear side of the interior of the refrigerating chamber 11. All the shelves 5 are arranged in sequence from top to bottom and are detachably fixedly connected to the sheet metal column through a shelf bracket 51. The shelves 5 are used to place cold chain food so that the outside of the cold chain food is always kept at a low temperature to extend its storage time. The number of the shelves 5 and the spacing between the shelves 5 can be determined according to the volume of the cold chain food.

[0037] The refrigeration system 2 includes a circuit composed of a refrigerant compression unit, a condenser 21 and an evaporator 22 connected in sequence. The refrigerant compression unit is arranged at the rear side of the foam cabinet 1, and the evaporator 22 is arranged inside the circulating air chamber, and an evaporation fan 23 is arranged on one side. The condenser 21 is arranged above the top of the foam cabinet 1, and a condensation fan 24 is arranged on one side of the condenser 21. Specifically, the evaporator 22 and the evaporation fan 23 are installed in the bottom air duct 41 (such as Figure 2 At the same time, the evaporator 22 and the evaporation fan 23 can also be installed in the back duct 42 (as shown in FIG. Figure 1 The above two installation structures are essentially the same. The structure of the complete vertical refrigeration display cabinet does not occupy the bottom space of the cabinet, which not only reduces the front height but also increases the display area and volume.

[0038] One, two or more compressors 25 can be provided according to the length of the cabinet. By increasing the number of compressors, the vibration of a single compressor can be reduced to reduce the system noise. The refrigerant compression unit of this embodiment includes two compressors 25, and the two compressors 25 are fixedly mounted on the back outer side of the foaming cabinet 1. The number of compressors is actually determined according to the length of the foaming cabinet 1 or the volume of the cold storage room 11. The exhaust port of each compressor 25 is connected to the inlet pipeline of the condenser 21 through the liquid storage tank 27 and the throttling device 26 in turn. The air inlet of each compressor 25 is connected to the outlet pipeline of the evaporator 22, and the evaporator 22 is connected to the outlet pipeline of the condenser 21 through the expansion valve 28 arranged at the inlet thereof.

[0039] The refrigerant cycle starts from the exhaust of each compressor, enters the condenser 21 through a separate welded pipeline, then enters the evaporator 22 through an independent throttling device 26, and finally returns to the filter bottle of each compressor through the return air pipeline. The compressor compresses the low-temperature and low-pressure refrigerant to complete the cycle. The compressors do not need to be connected in parallel, which can reduce vibration and noise and reduce material costs.

[0040] The heat dissipation device 3 is located above the condenser 21, and includes an air suction hood 31 and an exhaust duct 32. The air suction hood 31 is a bell-mouth structure, and the expanded end at the bottom of the air suction hood 31 is located directly above the condensing fan 24. Its upper end is connected to one end of the exhaust duct 32 through the heat exhaust fan 33, and the other end of the exhaust duct 32 extends to the outdoors. During operation, the heat dissipation device 3 absorbs the heat released by the condenser 21 and discharges it to the outdoors. The refrigerant releases heat inside the condenser 21, and the heat released by the coil of the condenser 21 is blown upward into the air suction hood 31 through the condensing fan 24 on one side thereof. The heat exhaust fan 33 located above the air suction hood 31 discharges the hot air to the outdoors through the exhaust duct 32, thereby reducing the load of the indoor air conditioning system and achieving energy saving and consumption reduction.

[0041] Embodiment 2, combined Figure 6 and Figure 7 The complete vertical refrigeration display cabinet with a heat dissipation device disclosed in Example 2 has basically the same structure as the complete vertical refrigeration display cabinet disclosed in Example 1, and the functional effects achieved are basically the same. The working principles of the two are also basically the same. The difference is that the front side of the foaming cabinet body 1 disclosed in Example 2 is configured with a glass door body 6, and a handle 61 is installed on one side of the glass door body 6. The cold storage room 11 of the vertical refrigeration display cabinet can be closed through the glass door body 6, which can effectively reduce the loss of cold air and achieve further energy saving and consumption reduction.
