Fig. 1 is a schematic partial block diagram of a refrigerated display case according to an embodiment of the present utility model, as shown in fig. 1, and referring to fig. 2 to 4, the embodiment of the present utility model provides a refrigerated display case including a case 100, a door body, and a first heat exchanger 200. The housing 100 has a housing cavity 110 formed therein, which is open forward. The door body is movably installed at the forward opening of the receiving chamber 110 to open or close the forward opening. The first heat exchanger 200 is disposed at the bottom of the accommodating chamber 110, the refrigerant flows in the first heat exchanger 200, and the refrigerant flows in the first heat exchanger 200 from front to back.

In this embodiment, the door body is installed at the forward opening of the accommodating cavity 110, the first heat exchanger 200 is disposed at the bottom of the accommodating cavity 110, and the first heat exchanger 200 has the refrigerant flowing from front to back. Since the temperature of the refrigerant exiting from the compressor is far lower than the external temperature, the refrigerant can absorb external heat while flowing in the first heat exchanger 200, thereby reducing the external temperature and increasing the temperature thereof. With the flowing of the refrigerant, the temperature of the refrigerant gradually increases, so that the heat which can be absorbed gradually decreases, and the temperature of the area through which the refrigerant flows is lower than that of the area through which the refrigerant flows. In this embodiment, the cooling flows from front to back in the first heat exchanger 200, so that the front temperature of the accommodating cavity 110 is lower than the rear temperature, and the temperature of the door area caused by escape of the cooling air in the area near the door can be made up for being higher than the temperature in the refrigeration display cabinet, so that the temperatures of all areas in the refrigeration display cabinet are balanced, and further, the temperatures of foods in all areas of the refrigeration display cabinet are similar, and the user satisfaction is improved.

In some embodiments of the present utility model, the first heat exchanger 200 includes a plurality of heat exchange tubes 210 and a plurality of arc-shaped connection tubes 220. The plurality of heat exchange tubes 210 are disposed in parallel and at intervals in the front-rear direction. Every two adjacent heat exchange tubes 210 are communicated through an arc-shaped connecting tube 220. One end of one heat exchange tube 210 located at the front is communicated with the fluid inlet tube 310; one end of one heat exchange tube 210 located at the rear communicates with the fluid outlet tube 320. Since the plurality of heat exchange tubes 210 are disposed in parallel in the front-rear direction, one end of the front one of the heat exchange tubes 210 communicates with the fluid inlet tube 310, and the refrigerant flows into the heat exchange tube 210 located at the forefront through the fluid inlet tube 310 and flows in the horizontal direction. Meanwhile, since each two adjacent heat exchange tubes 210 are communicated through the arc-shaped connection tube 220, when the refrigerant flows to the end in one heat exchange tube 210, the refrigerant flows into the heat exchange tube 210 at the rear through the arc-shaped connection tube 220, so that the refrigerant flows in an S shape from the heat exchange tube 210 at the front to the heat exchange tube 210 at the rear, and finally flows out of the first heat exchanger 200 through the fluid outlet tube 320. By the arrangement, the contact area of the heat exchange tube 210 and the heat exchange space where the heat exchange tube is positioned is increased, a good heat exchange effect is realized, meanwhile, the refrigerant flows back and forth from front to back, and the effect that the front temperature of the accommodating cavity 110 is lower than the rear temperature is realized, so that the temperature imbalance of each area in the refrigeration showcase caused by escape of cold air in the area near the door body can be compensated.

In some embodiments of the present utility model, at least two of the first heat exchangers 200 are provided, and at least two of the first heat exchangers 200 are disposed in parallel; the first heat exchanger 200 is disposed in the accommodating chamber 110 in the left-right direction in sequence. Also, since the receiving chamber 110 is generally a long and narrow geometry having a length much longer than a width in the related art, and only one of the first heat exchangers 200, the flow path of the refrigerant in the heat exchange tube 210 is excessively long. The refrigerant absorbs external heat in the flowing process, the temperature of the refrigerant rises, the temperature difference between the refrigerant and the external air is smaller as the temperature of the refrigerant is higher, and the refrigerant is harder to absorb heat from the external, so that the temperature of a region through which the refrigerant flows first can be reduced quickly, and the temperature of a region through which the refrigerant flows last is difficult to reduce, and therefore, the refrigerating effect of each region is different. In the utility model, at least two first heat exchangers 200 are arranged, so that the refrigerant in each first heat exchanger 200 only flows in the heat exchange tube 210 of the area, the flow path of the refrigerant in the single first heat exchanger 200 is effectively reduced, and the temperature in the area is relatively balanced. That is, by arranging the plurality of first heat exchangers 200, the accommodating cavity 110 is also divided into a plurality of areas to be subjected to heat exchange, one first heat exchanger 200 corresponds to one area, and the refrigerant in each heat exchanger only needs to have a very short flowing path, so that the temperature in each area is relatively balanced, and the plurality of first heat exchangers 200 are arranged in parallel, so that the temperatures among the areas are relatively balanced, and finally the refrigerating effect of the areas in the accommodating cavity 110 is similar.

In some embodiments of the present utility model, as shown in fig. 2, the first heat exchanger 200 further includes a fixing bar 230 provided with a plurality of fixing holes 231, and one heat exchange tube 210 is positioned in one fixing hole 231. Further, the first heat exchanger 200 further includes a cold permeable plate 240, and the cold permeable plate 240 is disposed above the heat exchange tube 210 and connected to the fixing strip 230; the cooling plate 240 is provided with a plurality of cooling holes 241. By this arrangement, the heat exchange tube 210 is limited in the fixing hole 231, so that the heat exchange tube 210 cannot move, and stable operation of the first heat exchanger 200 is not affected. On the other hand, the heat exchange tube 210 is limited in the fixing hole 231, and the cooling permeable plate 240 is arranged on the fixing strip 230, so that the fixing strip 230 can support the cooling permeable plate 240, and the situation that the cooling permeable plate 240 is directly placed on the heat exchange tube 210, and articles such as food, dinner plates and the like on the cooling permeable plate 240 deform the heat exchange tube 210 to affect the use of the first heat exchanger 200 is avoided. Meanwhile, the heat exchange tube 210 positioned below the cold permeable plate 240 absorbs heat of surrounding air, so that the air is cooled, and low-temperature air can be diffused to an area above the cold permeable plate 240 through the cold permeable holes 241, thereby improving the refrigerating efficiency.

In some embodiments of the present utility model, in order to facilitate maintenance of the first heat exchanger 200, the number of the cold permeable plates 240 is plural, and the plurality of cold permeable plates 240 are sequentially laid over the heat exchange tubes 210 in the left-right direction. Because the number of the cooling-permeable plates 240 is plural, only one cooling-permeable plate 240 can be detached during maintenance, and the partial heat exchanger below the cooling-permeable plates 240 is maintained, so that the problems of taking down and troublesome operation of the whole large cooling-permeable plate 240 when maintenance is required in the prior art are avoided.

In some embodiments of the present utility model, at least two of the door bodies are movably mounted at the forward opening of the receiving chamber 110. When the two door bodies completely block the forward opening, the edges of the two door bodies are contacted and abutted. When the forward opening is to be opened, one door body is pushed to be overlapped with the other door body, so that the part of the forward opening is blocked, and a user can take out an article from the accommodating cavity 110 or put the article into the accommodating cavity 110 through the unblocked area. Meanwhile, the two door bodies can move, so that the accommodating cavity 110 is communicated with the outside through different positions of the forward opening, and a user can conveniently take and put articles in different areas. Further, the door body is made of a transparent material so that a user can directly see the condition inside the receiving space.

In some embodiments of the present utility model, to increase the cooling efficiency, the refrigerated display case further includes an air cooling assembly 400, as shown in fig. 3 and 4. The air cooling assembly 400 is disposed at the top of the accommodating chamber 110 and configured to blow air downward. Air-cooled assembly 400 includes a housing 410, a fan 420, and a second heat exchanger 430. The casing 410 is provided with an air inlet 411 and an air outlet 412 with a downward opening. The fan 420 is disposed at the air outlet 412. The second heat exchanger 430 is located between the air outlet 412 and the fan 420. The second heat exchanger 430 is configured to flow a refrigerant.

In this embodiment, since the air cooling assembly 400 is additionally provided, and the air cooling assembly 400 is configured to blow downwards, the air in the accommodating cavity 110 is promoted to circulate, and in the flowing process, the low-temperature air around the first heat exchanger 200 drives the air to each region in the accommodating cavity 110, so that the temperature of each region in the accommodating cavity 110 is rapidly reduced, and the refrigeration efficiency is effectively improved. Meanwhile, since the second heat exchanger 430 is further disposed between the air outlet 412 of the air cooling assembly 400 and the air blower 420, under the action of the air blower 420, air in the accommodating cavity 110 enters the casing 410 from the air inlet 411, exchanges heat with the second heat exchanger 430 after passing through the air blower 420, and flows into the accommodating cavity 110 from the air outlet 412 after the temperature is reduced, so that the air cooling assembly 400 can promote the air flow and reduce the temperature in the accommodating cavity 110.

In some embodiments of the present utility model, in order to achieve both space utilization and refrigeration effect of the receiving cavity 110, the refrigerated display case further includes a storage plate 500, where the storage plate 500 is horizontally disposed in the receiving cavity 110. The storage plate 500 is provided with a first ventilation area 510 and a second ventilation area 520 at intervals along the front-rear direction. The first ventilation area 510 and the second ventilation area 520 are each provided with a plurality of ventilation holes. In the first ventilation zone 510, the air flow passes through the ventilation holes from below the storage plate 500 to above the storage plate 500; in the second venting area 520, airflow passes from above the storage panel 500 through the vents to below the storage panel 500. Because the accommodating cavity 110 is internally provided with the accommodating plate 500, articles can be placed on the accommodating plate 500, and meanwhile, the accommodating plate 500 is provided with the first ventilation area 510 and the second ventilation area 520, air flow can pass through the first ventilation area 510 and the second ventilation area 520 to flow up and down, and the air flow in the accommodating space can not be blocked to flow circularly, so that the space utilization rate and the refrigerating effect of the accommodating cavity 110 are both considered.

Further, in order to increase the space utilization of the refrigerated display cabinet, the number of the storage boards 500 is plural; a plurality of sets of shelf 600 distributed along the vertical direction are provided on the rear wall of the housing 100, and each set of shelf 600 extends into the accommodating cavity 110. One storage plate 500 is positioned on a set of shelves 600, and each storage plate 500 can be used for storing articles, so that the space utilization rate of the refrigerated display cabinet is improved.
