Technical Field

[0001] The utility model belongs to the technical field of refrigeration equipment, and more specifically, relates to a refrigeration device for cold chain transportation. Background Art

[0002] At present, cold chain transport refrigeration equipment or fixed cold storage generally has a refrigeration unit installed on the ceiling. These equipments apply the principle of natural refrigeration, and there is usually no wind or weak wind around the refrigeration unit. When the refrigeration unit is working, especially when the door of the equipment is opened or closed, the hot air encounters cold air, causing a large amount of water to condense quickly on the surface of the refrigeration unit and drip downwards. The condensed water dripping onto the goods or people below may contaminate the goods and make people feel uncomfortable.

[0003] Some fixed cold storage or transportation equipment will add a tray at the bottom of the refrigeration release unit. Although the dripping condensed water can be collected, the tray will be affected by the low-temperature condensed water and its own temperature will also drop, resulting in a large amount of secondary condensed water still being generated and dripping at the bottom of the tray.

[0032] Now, the refrigeration device for cold chain transportation provided by the present utility model will be described.

[0033] Please refer to Figure 1 、 Figure 2 and Figure 3The refrigeration device for cold chain transportation includes a box body 1, multiple cold release units 2, multiple drainage trays 3 and a collecting and draining mechanism 4, wherein the multiple cold release units 2 are arranged in parallel and evenly on the inner top surface of the box body 1, and a circulation pipe 201 is connected to each cold release unit 2, and the circulation pipe 201 is connected to an external refrigeration device; multiple drainage trays 3 correspond to the cold release units 2 one by one, and the drainage tray 3 includes a tray body 301 and an isolation mechanism 302, the tray body 301 is received under the corresponding cold release unit 2, and the isolation mechanism 302 isolates the bottom surface of the tray body 301 from the air in the box body 1; the collecting and draining mechanism 4 is arranged at both ends of the drainage tray 3, and the collecting and draining mechanism 4 is connected to the inner cavity of each tray body 301, and the collecting and draining mechanism 4 is used to collect condensed water in the tray body 301 and discharge it from the box body 1.

[0034] The beneficial effect of the refrigeration device for cold chain transportation provided by the present embodiment is as follows: compared with the prior art, the refrigeration device for cold chain transportation provided by the present embodiment is provided with a drainage tray 3, and the drainage tray 3 includes a tray body 301 and an isolation mechanism 302. The tray body 301 is received under the corresponding cold release unit 2 to receive the condensed water falling from the cold release unit 2. The isolation mechanism 302 isolates the bottom surface of the tray body 301 from the air in the box body 1, so that even if the tray body 301 is cooled, it cannot come into contact with the outside air, and thus cannot produce secondary condensed water, thereby effectively preventing the secondary condensed water from contaminating the goods in the cold chain transportation, and greatly improving the safety of the cold chain transportation.

[0035] In this embodiment, the tray body 301 is integrally formed, the middle of the tray body 301 is concave to form a drainage groove 305, and the two side walls of the drainage groove 305 are arranged at an angle. Specifically, the tray body 301 can be manufactured by extrusion molding, which is simple to manufacture and can be cut to length as needed. The setting of the drainage groove 305 can temporarily store the condensed water dripping from the cooling release mechanism, and the inclined arrangement of the two side walls of the drainage groove 305 can facilitate the condensed water to be concentrated at the bottom of the drainage groove 305.

[0036] like Figure 5 As shown, the intersection of the two side walls of the drainage groove 305 is rounded so that the collected condensed water can be quickly gathered and easily flow from one end to the other.

[0037] In addition, the isolation mechanism 302 includes two plugging plates 304 and a lower sealing plate 303. The lower sealing plate 303 is U-shaped, and the top of the lower sealing plate 303 is connected to the tray body, so that the drainage tray 3 and the lower sealing plate 303 enclose the drainage pipe 402, and the side wall of the drainage groove 305 is coated on the inner side of the lower sealing plate 303, and the plugging plates 304 are respectively blocked at both ends of the drainage pipe 402. Due to the use of a structure similar to a square tube, it is light in weight, has high structural strength, and is easy to process, which is suitable for industrial mass production. In addition, the bottom of the tray body 301 can only contact with the air inside the drainage pipe 402, thereby reducing the heat conduction between the sealing plate and the tray body 301, so that the bottom of the sealing plate will not produce secondary condensed water. Of course, in addition to the sealing plate and the plug, the isolation mechanism 302 can also be a layer of thermal insulation material. The selected thermal insulation material must isolate the bottom of the tray body 301 from the air in the box body 1.

[0038] In this embodiment, the cooling unit 2 is in a rectangular shape, the width of the drainage groove 305 of the drainage tray 3 is greater than the width of the cooling unit 2, and the length of the drainage tray 3 is greater than the length of the cooling unit 2, so as to receive all the dripping condensed water. Generally, the drainage tray 3 is kept at an appropriate distance from the cooling unit 2 to reduce the impact on the cooling efficiency.

[0039] As a preferred technical solution, a reinforcing rib that follows the shape of the drain pipe 402 is provided on the inner wall of the drain pipe 402. The provision of the reinforcing rib can increase the strength of the drain tray 3 and prevent the drain tray 3 from breaking.

[0040] like Figure 2 and Figure 4 As shown, a plurality of crossbeams 101 are provided on the inner top wall of the box body 1, and the crossbeams 101 extend along the width direction of the box body 1, and the plurality of crossbeams 101 are evenly arranged along the length direction of the box body 1. The cooling unit 2 extends along the length direction of the box body 1, and the plurality of cooling units 2 are evenly arranged along the width direction of the box body 1; a plurality of first fixing hoops 306 are arranged corresponding to each cooling unit 2, and the first fixing hoops 306 correspond to the crossbeams 101 one by one, and the first fixing hoops 306 are sleeved on the corresponding cooling unit 2, and the top of the first fixing hoops 306 is fixed on the corresponding crossbeam 101, and a safety hoop 307 is provided on the inner side of the first fixing hoop 306, and the safety hoop 307 is sleeved on the cooling unit 2. The arrangement of the first fixing hoop 306 and the crossbeam 101 can facilitate the fixing of the cooling unit 2 on the inner top wall of the box body 1. The arrangement of the safety hoop 307 can facilitate the first fixing hoop 306 to fix the cooling unit 2 more firmly.

[0041] like Figure 4As shown, a plurality of second fixing hoops 308 are provided on each drainage tray 3. The second fixing hoops 308 conform to the shape of the drainage tray 3, and the second fixing hoops 308 are sleeved on the drainage tray 3. The second fixing hoops 308 correspond to the first fixing hoops 306 one by one, and the top of the second fixing hoops 308 is fixed to the bottom of the corresponding first fixing hoops 306. In this embodiment, the second fixing hoops 308 include an upper half hoop and a lower half hoop, and the upper half hoop and the lower half hoop are fixed by bolts. A connecting member is provided between the second fixing hoops 308 and the first fixing hoops 306. The top of the connecting member is welded to the bottom of the first fixing hoops 306, and the bottom of the connecting pipe is welded to the top of the upper half hoop.

[0042] Finally, the collection and drainage mechanism 4 includes a water collection tank 401, a drain pipe 402 and a reserved pipe. The water collection tank 401 is communicated with the drainage groove 305. The drain pipe 402 is arranged at one end of the water collection tank 401. The reserved pipe is arranged in the side wall of the box body 1. The drain pipe 402 is connected to the top of the reserved pipe, and the bottom end of the reserved pipe is arranged outside the box body 1. The water gathered in the drainage groove 305 flows into the water collection tank 401, and the water in the water collection tank 401 is discharged through the drain pipe 402 and the reserved pipe, preventing the condensate water from polluting the goods transported in the box body 1.

[0043] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
