Description

Technical Field

[0001] The utility model relates to the technical field of warehouse ventilation, in particular to a ventilation device for a cold chain warehouse. Background Art

[0002] The main function of a cold chain warehouse is to maintain a low-temperature environment to extend the shelf life of perishable foods. However, while maintaining a low temperature, the air quality and humidity control inside the warehouse are also very important. Appropriate ventilation can help regulate the air humidity inside the warehouse and prevent goods from getting damp or moldy due to excessive humidity. In addition, ventilation also helps reduce the accumulation of odors and harmful gases inside the warehouse and keep the air inside the warehouse fresh.

[0003] The patent with the publication number CN217785574U discloses a cold storage ventilation and air change device, including a cold storage, a top intake pipe and a top exhaust pipe; the top intake pipe is arranged directly above the top surface outside the cold storage, with an inclined axis, one end being lower and the other end being higher; the lower end of the top intake pipe is connected to the top of one end of the cold storage and is in communication; a condensate discharge hole is provided at the lower end of the top intake pipe, and the higher end is the air inlet; the top exhaust pipe is also arranged directly above the top surface outside the cold storage, with its axis arranged in parallel with the axis of the top intake pipe, one end being lower and the other end being higher; the lower end of the top intake pipe is connected to the top of one end of the cold storage and is in communication, and its side wall abuts against the side wall of the top intake pipe, and the higher end is the exhaust port. Dehumidification is carried out by means of the cold air flowing out of the cold storage.

[0004] However, since the temperature of the air entering the cold storage is relatively higher than the room temperature inside the cold storage, continuous ventilation and air change will cause the indoor temperature of the cold storage to rise rapidly, thereby increasing the burden on the refrigeration equipment in the cold storage and consuming a large amount of energy. Summary of the Utility Model

[0005] In view of the above problems, the utility model provides a ventilation device for a cold chain warehouse.

[0006] In order to achieve the above invention purpose, the technical scheme adopted by the utility model is as follows:

[0007] There is provided a ventilation device for a cold chain warehouse, including an intake pipe and an exhaust pipe. The first end of the intake pipe is connected to the warehouse and the other end is connected to the outside. An intake fan is arranged on the intake pipe, and an exhaust fan is arranged on the exhaust pipe. It further includes a heat exchange sleeve. Both the intake pipe and the exhaust pipe are connected to the heat exchange sleeve. The heat exchange sleeve includes an outer sleeve and an inner tube coaxially sleeved. Both ends of the inner tube are connected to the exhaust pipe, and both ends of the outer sleeve are connected to the intake pipe. A heat exchange structure and a drainage structure are arranged inside the heat exchange sleeve. The drainage structure is used for collecting and discharging the condensate on the surface of the inner tube.

[0008] Further, the heat exchange structure includes fins, which are fixedly arranged on the outer wall of the inner pipe. A support rod is arranged between the inner pipe and the outer sleeve pipe, and both ends of the support rod are fixedly connected to the inner pipe and the outer sleeve pipe respectively.

[0009] Further, the inner pipe is in a spiral shape.

[0010] Further, the heat exchange sleeve is horizontally arranged. The drainage structure includes absorbent cotton. A drain pipe is fixedly connected to the bottom of the outer sleeve pipe. A water collecting cylinder is detachably connected to the bottom of the drain pipe. The absorbent cotton is filled in the drain pipe, and the bottom end of the absorbent cotton extends into the water collecting cylinder. A communication groove is axially formed through the drain pipe along its own axis.

[0011] Further, a water collecting surface inclined towards the drain pipe is arranged on the inner wall of the outer sleeve pipe.

[0012] Further, a water collecting part is arranged at one end of the inner pipe close to the indoor side, and the outer wall of the water collecting part is spherical.

[0013] The beneficial effects of the present utility model are as follows: When the air inlet fan and the air outlet fan are regularly turned on to renew the air in the warehouse, the heat exchange sleeve exchanges heat between the normal-temperature air in the air inlet pipe and the low-temperature air in the air outlet pipe, reducing the temperature change in the warehouse during the ventilation process. At the same time, the drainage structure collects the condensed water generated during the heat exchange process, preventing the condensed water from entering the warehouse and causing the warehouse floor to be slippery.

Detailed Embodiments

[0017] In order to better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the drawings of the specification and specific embodiments.

[0018] An embodiment of the present application discloses a ventilation device for a cold chain warehouse 3. Refer to Figure 1 and Figure 2, including an air inlet pipe 1, an air outlet pipe 2 and a heat exchange sleeve 4. One end of the air inlet pipe 1 is connected with an air inlet fan 11, and the other end is communicated with the inside of the warehouse 3. One end of the air outlet pipe 2 is connected with an air outlet fan 21, and the other end is communicated with the inside of the warehouse 3. Both the air inlet pipe 1 and the air outlet pipe 2 are connected with the heat exchange sleeve 4. Specifically, the heat exchange sleeve 4 includes an outer sleeve 41 and an inner pipe 42. The inner pipe 42 coaxially penetrates through the outer sleeve 41. Both ends of the inner pipe 42 are connected in series with the air outlet pipe 2. Both ends of the outer sleeve 41 are connected in series with the air inlet pipe 1. A heat exchange structure and a drainage structure 7 are provided inside the heat exchange sleeve 4. The heat exchange structure is used for exchanging heat between the normal temperature air sent into the air inlet pipe 1 and the low-temperature cold air sent out from the air outlet pipe 2 in the cold storage. The drainage structure 7 is used for collecting and discharging the condensed water on the surface of the inner pipe 42.

[0019] In the embodiment of the present application, the heat exchange structure includes fins 5. The fins 5 are fixed on the outer wall of the inner pipe 42. Both the inner pipe 42 and the fins 5 are made of copper material. A support rod 6 is provided between the inner pipe 42 and the outer sleeve 41. Both ends of the support rod 6 are respectively fixedly connected with the inner pipe 42 and the outer sleeve 41, so as to stably fix the inner pipe 42 in the outer sleeve 41. A heat-insulating cotton sleeve is sleeved outside the outer sleeve 41 and on the outer sides of the air inlet pipe 1 and the air outlet pipe 2 between the heat exchange sleeve 4 and the warehouse 3. Further, the inner pipe 42 is in a spiral shape, which can increase the passing distance of the low-temperature air in the inner pipe 42, and thus improve the heat exchange efficiency of the heat exchange sleeve 4.

[0020] The heat exchange sleeve 4 is horizontally installed. The drainage structure 7 specifically includes a water-absorbing cotton 71, a drain pipe 72 and a water collection cylinder 73. The top end of the drain pipe 72 is vertically connected to the bottom of the outer sleeve 41. The water collection cylinder 73 is detachably connected to the bottom end of the drain pipe 72. The water collection cylinder 73 is communicated with the inside of the outer sleeve 41 through the drain pipe 72. The water-absorbing cotton 71 is filled in the drain pipe 72, and both ends of the water-absorbing cotton 71 respectively extend into the outer sleeve 41 and the water collection cylinder 73. The water collection cylinder 73 can be threadedly connected to the drain pipe 72. The water collection cylinder 73 can be made of a transparent material, which is convenient for observing the condensed water collected in the water collection cylinder 73.

[0021] During the heat exchange process of the inner pipe 42 and the fins 5, condensed water will condense on the surfaces of the inner pipe 42 and the fins 5. The condensed water drops onto the lower outer sleeve 41. After being adsorbed by the water-absorbing cotton 71, the condensed water drops into the water collection cylinder 73 for collection, which can prevent the condensed water in the water collection cylinder 73 from being sucked into the warehouse 3 during the process of sending air into the warehouse 3 through the air inlet pipe 1. A communication groove 75 is axially penetrated along the drain pipe 72 itself. Through the communication groove 75, the air pressure in the water collection cylinder 73 and the drain pipe 72 can be kept uniform, so that the condensed water in the water-absorbing cotton 71 can smoothly drip downward.

[0022] Furthermore, a water collecting surface 74 inclined towards the drain pipe 72 is provided on the inner wall of the outer sleeve 41, which can enable the condensed water at the bottom of the outer sleeve 41 to flow smoothly towards and gather in the drain pipe 72. A water collecting part 421 is provided at one end of the inner pipe 42 close to the interior, and the outer wall of the water collecting part 421 is spherical. Through the water collecting part 421, the condensed water at one end of the inner pipe 42 close to the warehouse 3 can be blocked by the water collecting part 421, preventing the condensed water from flowing along the inner pipe 42 into the air inlet pipe 1.

[0023] By performing heat exchange on the air in the air inlet pipe 1 and the exhaust pipe 2 of the cold chain warehouse 3, the refrigeration energy consumption of the cold storage can be reduced, the temperature change during the ventilation and air exchange process of the cold chain warehouse 3 can be reduced, and at the same time, the condensation water droplets falling into the warehouse 3 can be avoided, preventing the ground from becoming slippery.
