Description

Technical Field

[0001] This utility model relates to the field of heat dissipation technology for grain warehouse ventilation openings, and in particular to a radiative heat insulation and cooling device for grain warehouse ventilation openings. Background Technology

[0002] In grain and oil storage facilities, the heat insulation effect of tall, flat warehouse doors, windows, and ventilation openings is of great significance for ensuring food security. Improving the storage conditions of warehouses and upgrading their hardware facilities are the basic guarantees for implementing scientific grain preservation and reducing grain storage losses.

[0003] In hot and humid regions, summers are long, with high temperatures typically lasting 6-8 months. Noon temperatures can reach 36-40℃. Ground ventilation openings are often simple in structure and lack self-heating equipment, resulting in limited insulation and poor heat dissipation. As temperatures continue to rise under direct sunlight in summer, more heat seeps into the grain silos, easily leading to problems such as grain overheating, moisture transfer, and pest infestation, which endanger food safety.

[0004] Therefore, how to design a radiant heat insulation material ventilation outlet cooling modification device that can solve the above-mentioned technical problems is a technical problem that needs to be solved. Utility Model Content

[0005] In order to solve the above problems, the purpose of this utility model is to provide a radiative heat insulation and cooling device for the ventilation opening of a grain warehouse, which solves the problems of poor heat insulation effect and poor heat dissipation effect of the heat dissipation opening.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: It includes a heat dissipation shroud and a cooler fixedly mounted on the air inlet side of the heat dissipation shroud; several air inlet holes are opened on one side wall of the heat dissipation shroud, and several first cooling fans are arranged and installed facing forward on the inner side of the air inlet holes; several air outlet holes are opened on the side wall of the heat dissipation shroud opposite to the air inlet holes, and several vertical ventilation holes are opened on the top end face of the heat dissipation shroud; first and second water-cooling radiators are respectively installed on the inner side of the air outlet holes and the vertical ventilation holes; several second and third cooling fans are respectively arranged and installed in opposite directions on the inner side of the first and second water-cooling radiators; a coolant tank is provided on the inner side wall of the heat dissipation shroud corresponding to the air inlet holes, and the inlet and outlet of the coolant tank are respectively connected to… The device includes an inlet pipe and an outlet pipe for contacting the outer wall of the vent. The inlet pipe is installed inside the heat sink and connected sequentially to the second and first water-cooling radiators. The outlet pipe is connected to the outlet of the first water-cooling radiator. A sealing partition is horizontally installed at the bottom of the air cooler, dividing the internal space of the air cooler into an air intake chamber and a water storage chamber. The air intake chamber has a window connected to the air intake hole on the side opposite to the air intake hole of the heat sink. Several ventilation holes are provided on the side wall of the air intake chamber away from the air intake hole and on the left and right side walls. Wet curtains are fixed on the inner side wall of the air intake chamber at the positions corresponding to the ventilation holes. A water pump is installed in the water storage chamber. A water spray pipe is installed at the outlet of the water pump. The water spray pipe extends through the sealing partition into the air intake chamber and is located above the wet curtains.

[0007] Furthermore, the water spray pipe is connected to several water spray branch pipes, which pass through the wet curtain and are located inside the wet curtain.

[0008] Furthermore, the edge of the wet curtain is fixedly connected to the inner wall of the air intake cavity by fastening bolts.

[0009] Furthermore, the inner wall of the air intake cavity is also fixed with several fixing brackets for fixing the wet curtain at the positions of several ventilation holes.

[0010] Furthermore, three fixed brackets are provided on each side wall, and they are respectively located at the top, middle and bottom positions of the side wall.

[0011] Furthermore, the outer side walls of the heat dissipation cover away from the air inlet and outlet are covered with a heat insulation film.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model provides a wet curtain on the inner wall of the air cooler. When the first cooling fan is working, the positive pressure generated draws outside air into the air cooler through the vent and the wet curtain. The water on the wet curtain evaporates under adiabatic conditions, carrying away a large amount of latent heat from the air, thereby cooling the air, increasing oxygen supply, and purifying it, so as to reduce the air temperature.

[0014] 2. This utility model adds a heat dissipation cover to the outside of the heat dissipation port. Under the negative pressure of the first heat dissipation fan, the cold air generated by the cooler is sent into the heat dissipation cover. The second and third heat dissipation fans installed in the direction of the passage accelerate the air circulation speed in the heat dissipation cover, thereby reducing the heat on the outer wall of the heat dissipation port and thus achieving the cooling of the heat dissipation port.

[0015] 3. This utility model sets up a coolant tank inside the heat dissipation port and lays an inlet pipe inside the heat dissipation shroud. The coolant tank is connected to the second water cooling radiator and the first water cooling radiator in sequence through the inlet pipe. Finally, it completes the circulation through the outlet pipe connected to the outlet end of the first water cooling radiator. The coolant carries away the heat of the outer wall of the heat dissipation port through the inlet pipe and dissipates the heat through the first water cooling radiator and the second water cooling radiator, so as to achieve the cooling of the heat dissipation port.

[0016] 4. This utility model improves the heat dissipation effect by covering both sides of the heat sink with heat insulation film, has low installation cost, and is widely applicable. Attached Figure Description

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0023] See Figure 1-2As shown, the solution includes a heat dissipation shroud 1 and a cooler 2 fixedly installed on the air inlet side of the heat dissipation shroud 1.

[0024] The heat sink shroud 1 has several air inlet holes 11 on one side wall, and several first cooling fans 12 are installed in a forward-facing arrangement on the inner side of the air inlet holes 11. The heat sink shroud 1 has several air outlet holes 13 on the side wall opposite to the air inlet holes 11, and several vertical ventilation holes 14 are provided on the top end face of the heat sink shroud 1. First water cooling radiators 15 and second water cooling radiators 16 are respectively installed on the inner side of the air outlet holes 13 and the vertical ventilation holes 14. The inner side of the first water cooling radiators 15 and the second water cooling radiators 16 are evenly distributed... A number of second cooling fans 17 and third cooling fans 18 are installed in opposite directions. A coolant tank 19 is provided on the inner side wall of the heat dissipation shroud 1 on the side corresponding to the air inlet vent 11. The inlet end and outlet end of the coolant tank 19 are respectively connected to an inlet pipe 191 and an outlet pipe 192 for contacting the outer side wall of the vent. The inlet pipe 191 is arranged inside the heat dissipation shroud 1 and is connected in sequence to the second water cooling radiator 16 and the first water cooling radiator 15. The outlet pipe 192 is connected to the outlet end of the first water cooling radiator 15.

[0025] A sealing partition 21 is horizontally installed at the bottom of the air cooler 2, dividing the internal space of the air cooler 2 into an air intake chamber 22 and a water storage chamber 23. The air intake chamber 22 has a window 24 connected to the air intake hole 11 on the side opposite to the air intake hole 11 of the heat dissipation shroud 1. Several ventilation holes 25 are provided on the side wall of the air intake chamber 22 away from the air intake hole 11 and on both the left and right side walls. Wet curtains 26 are fixedly installed on the inner side wall of the air intake chamber 22 at positions corresponding to the ventilation holes 25. A water pump 231 is installed in the water storage chamber 23, and a water spray pipe 232 is provided at the outlet of the water pump 231. The water spray pipe 232 extends through the sealing partition 21 into the air intake chamber 22 and is positioned above the wet curtains 26. The wet curtains 26 are special paper with a large surface area and a corrugated honeycomb shape.

[0026] Furthermore, the water spray pipe 232 is connected to a plurality of water spray branch pipes 2321, which pass through the wet curtain 26 and are located inside the wet curtain 26.

[0027] The edge of the evaporative cooling pad 26 is fixedly connected to the inner wall of the air intake chamber 22 by fastening bolts. In order to increase the stability between the evaporative cooling pad 26 and the outer wall of the air cooler 2, in this embodiment, a number of fixing brackets for fixing the evaporative cooling pad 26 are also fixed at the positions of the corresponding air vents 25 on the inner wall of the air intake chamber 22. Optimally, three fixing brackets are provided on each side wall, and they are respectively located at the upper, middle and lower positions of the side wall.

[0028] The heat dissipation cover 1 is covered with a heat insulation film on both outer walls away from the air inlet 11 and the air outlet 13. The heat insulation film is composed of organic polymer materials and functional inorganic materials. Through the high infrared emission capability of the atmospheric transmission window 24 band, heat is continuously and efficiently transferred to the cold source in outer space. At the same time, the absorption of solar heat is minimized by utilizing the high reflectivity of solar radiation energy, thus achieving a significant cooling effect.

[0029] The working principle is roughly as follows:

[0030] The heat dissipation shroud 1 is placed over the outside of the heat dissipation opening. The first cooling fan 12, which is installed in the forward direction, operates, creating a negative pressure inside the heat dissipation shroud 1 and a positive pressure inside the air intake chamber 22 of the air cooler 2. Under the positive pressure of the first cooling fan 12, air from outside the air cooler 2 is drawn into the chamber through the vent 25 and the highly absorbent wet curtain 26. The water on the wet curtain 26 evaporates under adiabatic conditions, carrying away a large amount of latent heat. The cooled and oxygenated air enters the heat dissipation shroud 1 through the air inlet vent 11 (the stronger the wind force of the first cooling fan 12, the better the negative pressure effect inside the heat dissipation shroud 1). The second and third cooling fans, which are installed in the opposite direction, operate, blowing air outward, accelerating the speed of air entering and exiting the heat dissipation shroud 1, and displacing the hot air inside the heat dissipation shroud 1 more quickly.

[0031] In addition, when the coolant tank 19 is working, the coolant circulates sequentially through the inlet pipe 191, the second water radiator 16, the first water radiator 15, and the outlet pipe 192, which are arranged on the outer wall of the heat dissipation port. The coolant passes through the outer wall of the heat dissipation port and carries away the heat of the outer wall of the heat dissipation port. Then, it dissipates the heat through the water radiator, thereby reducing the temperature of the outer wall of the heat dissipation port.

[0032] The above description is only a specific embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural transformations made based on the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
