[0017] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the scheme of the present invention will be further described below. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0018] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Combine the following Figures 1 to 6 The specific embodiments of the present invention are described in detail.

[0020] This embodiment provides an integrated refrigeration device, including a cabinet 1, a ventilation assembly 4 and a refrigeration assembly 8. The cabinet 1 is formed with an evaporation chamber 2 and a condensation chamber 3, and the evaporation chamber 2 is a sealed chamber; the ventilation assembly 4 includes a return air port 5, an air supply port 6 and an evaporation fan 7, the return air port 5 and the air supply port 6 are both arranged on the cavity wall of the evaporation chamber 2 and are used to connect the space to be refrigerated, and the evaporation fan 7 is placed in the evaporation chamber 2 and is used to form an airflow entering from the return air port 5 and blowing out from the air supply port 6; the refrigeration assembly 8 includes an evaporator 9, a compressor 10, a condenser 11 and a capillary tube 12 which are connected in series to form a loop, the evaporator 9 is placed in the evaporation chamber 2 to exchange heat with the airflow, and the compressor 10, the condenser 11 and the capillary tube 12 are placed in the condensation chamber 3.

[0021] Cabinet 1 Specifically, the cabinet 1 includes a frame 13, an evaporation shell 16 and a condensation plate group; the frame 13 is formed with adjacent first installation areas 14 and second installation areas 15; the evaporation shell 16 is fixed in the first installation area 14, the evaporation shell 16 forms a sealed cavity, and the return air port 5 and the air supply port 6 are opened on the side wall of the evaporation shell 16; the condensation plate group includes a condensation top cover 17 arranged on the top surface of the second installation area 15, a condensation bottom plate 18 arranged on the bottom surface of the second installation area 15, and three condensation side plates 19 respectively arranged on three adjacent side surfaces of the second installation area 15, and the condensation plate group and the evaporation shell 16 enclose a condensation cavity 3. The independent arrangement of the evaporation shell 16 is conducive to forming the evaporation cavity 2 into a sealed cavity.

[0022] It is easy to understand that the so-called "sealed cavity" means that except for the return air port 5 and the supply air port 6, the rest of the evaporation cavity 2 is sealed, and only the air flow is allowed to enter from the return air port 5 and blow out from the supply air port 6. Specifically, sealant can be applied to the weld, and M-shaped sealing strips can be used to seal the joints of the components.

[0023] More specifically, two opposite condensing side plates 19 are each provided with an air inlet grid plate 20, and the remaining condensing side plate 19 is provided with a condensing fan 21. The condensing fan 21 guides the outside air to enter the condensing chamber 3 from the two air inlet grid plates 20, and blows out from the position of the condensing fan 21, so as to form a flowing gas to improve the heat dissipation effect of the condenser 11.

[0024] More specifically, the three side walls of the evaporation housing 16 that are not adjacent to the condensation chamber 3 are respectively provided with a return air port 5, an air supply port 6 and an access panel 26, and the access panel 26 is detachably mounted on the corresponding side walls of the evaporation housing 16. The access panel 26 facilitates the maintenance and replacement of the internal components of the evaporation housing 16. In detail, the access panel 26 can be detachably fixed to the evaporation housing 16 by means of bolts or the like.

[0025] More specifically, an operation screen 22 and an aviation plug interface 23 are provided on the maintenance panel 26. The operation screen 22 can control the start and stop of each component, and the aviation plug interface 23 can be connected to external electrical components, and the plugging is faster and more convenient.

[0026] More specifically, in this embodiment, a protection plate 27 is further provided on the outer side of the evaporation shell 16 .

[0027] Specifically, a drain pipe interface 25 is provided at the bottom of the evaporation chamber 2. When the airflow exchanges heat in the evaporation chamber 2, part of the gas is easily liquefied to form liquid, so in this embodiment, a drain pipe interface 25 is provided at the bottom of the evaporation chamber 2. When in use, the drain pipe interface 25 is sealed and connected to the external water collection structure to be able to discharge the liquefied liquid and avoid excessive water accumulation in the evaporation chamber 2.

[0028] Ventilation components 4 Specifically, both the return air outlet 5 and the supply air outlet 6 are provided with a connecting flange 24, which is more conducive to connecting the pipeline, so as to communicate with the refrigerated space through the pipeline.

[0029] Refrigeration components 8 It is easy to understand that the refrigeration principle is as follows: after the evaporator 9 exchanges heat with the airflow, the refrigerant is heated and vaporized into high-temperature gas, and the high-temperature gas is converted into high-temperature and high-pressure gas through the compressor 10. The high-temperature and high-pressure gas enters the condenser 11 and exchanges heat with the outside world and then liquefies into low-temperature and high-pressure liquid. The low-temperature and high-pressure liquid releases pressure through the capillary 12 to form a low-temperature and low-pressure liquid. The low-temperature and low-pressure liquid enters the evaporator 9 and exchanges heat with the airflow again, and the cycle continues. The gas in the space to be refrigerated enters the evaporation chamber 2 through the return air port 5 and exchanges heat with the refrigerant in the low-temperature and low-pressure liquid state. The gas temperature decreases, the refrigerant temperature increases, and the cooled gas is blown into the space to be refrigerated through the air supply port 6, thus achieving refrigeration.

[0030] Specifically, the refrigeration assembly 8 further includes an electric control box 28 to control the operation of various electrical components.

[0031] The working principle of the integrated refrigeration device of the present invention is as follows: When in use, the device is installed as a whole on the outside of the space to be refrigerated, and the return air inlet 5 and the supply air inlet 6 are connected to the space to be refrigerated through a pipe; after the device is started, the evaporating fan 7 is activated to guide the gas in the space to be refrigerated to enter the evaporating chamber 2 through the return air inlet 5 and exchange heat with the evaporator 9 for cooling, and then blown back into the space to be refrigerated from the supply air inlet 6 to achieve refrigeration.

[0032] It should be noted that the device has a cooling function when both the refrigeration component 8 and the ventilation component 4 are turned on, but has a ventilation function if only the ventilation component 4 is turned on and the refrigeration component 8 is turned off.

[0033] The above is only a specific implementation of the present invention, which enables those skilled in the art to understand or implement the present invention. Although detailed descriptions are given with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments, and they should all be covered by the protection scope of the claims.
