Abstract
Description
Technical Field
[0001] This utility model relates to the field of heat dissipation devices, and in particular to a heat dissipation device for a refrigerated dryer. Background Technology
[0002] The heat dissipation device of a refrigerated dryer is like a "radiator". Its core task is to effectively discharge the heat gained by the refrigerant during compression and the heat absorbed in the evaporator to the external environment of the machine. This ensures that the refrigerant can be smoothly condensed from a high-temperature, high-pressure gaseous state to a medium-temperature, high-pressure liquid state, thereby ensuring that the refrigeration cycle can operate continuously, efficiently, and stably, and ultimately achieve the purpose of cooling and drying the compressed air to the required dew point.
[0003] When a refrigerated air dryer is in use, it relies on a fan to allow air to pass through the heat exchanger, enabling the heat dissipation device to operate normally and dissipate the heat generated inside the air dryer in a timely manner. This ensures the stable operation of the equipment and extends its service life. However, when the fan runs for a long time, a lot of dust will accumulate on the surface of the heat exchanger, affecting the heat exchanger's heat exchange.
[0004] Therefore, those skilled in the art have provided a heat dissipation device for a refrigerated dryer to solve the problems mentioned in the background art. Utility Model Content

An axial flow fan unit is fixedly installed on both sides of the bottom surface of the fixing frame. The rear end face of the first mounting plate and the second mounting plate are fixedly provided with a snap-fit groove. A fixing frame is snapped onto opposite sides of the two snap-fit grooves.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Reference Figure 1-4 An embodiment of this utility model provides a heat exhaust device for a refrigerated dryer, including a fixed box 1, a heat exchanger 2 fixedly installed inside the fixed box 1, two air inlet pipes 16 fixedly installed on the upper side of one side of the heat exchanger 2, two air outlet pipes 17 fixedly installed on the lower side of one side of the heat exchanger 2, a first mounting plate 3 fixedly installed on the upper rear end face of the fixed box 1, and a second mounting plate 5 fixedly installed on the lower rear end face of the fixed box 1.
[0024] A fixing frame 4 is bolted to one side of the first mounting plate 3 and the second mounting plate 5. An axial flow fan unit 7 is fixedly installed on both sides of the bottom surface of the fixing frame 4. A snap-fit groove 10 is fixedly installed on the rear end face of the first mounting plate 3 and the second mounting plate 5. A fixing frame 11 is snapped onto one side of the two snap-fit grooves 10. A dustproof net 12 is fixedly installed inside the fixing frame 11.
[0025] Specifically, during use, a heat exchanger 2 is installed inside the fixed box 1. The heat exchanger 2 performs heat exchange and uses flat tubes instead of round tubes to increase the heat dissipation area, reduce wind resistance, and improve heat exchange efficiency. Two air inlet pipes 16 are fixed to the upper side of one side of the heat exchanger 2, allowing gas to enter the interior. An air outlet pipe 17 is fixed to the lower side of one side of the heat exchanger 2, discharging the gas after heat exchange. A first mounting plate 3 and a second mounting plate 5 are fixed to the upper and lower parts of the rear end face of the main body. The first mounting plate 3 and the second mounting plate 5 are fixed using fixing bolts 9 and a fixing bracket 4, allowing the fixing bracket 4 to be fixed in place. The rear end of the fixed box 1 remains stable. When in use, the fixed frame 4 can fix two sets of axial flow fans inside. When in use, the axial flow fans allow air to pass through the heat exchanger 2. The rear ends of the first mounting plate 3 and the second mounting plate 5 are both fixed with snap-fit grooves 10. When in use, the snap-fit grooves 10 can snap-fit the fixed frame 11 inside. When in use, the fixed frame 11 is equipped with a dustproof net 12 inside. The dustproof net 12 can be set at the rear end of the axial flow fan group 7. When the axial flow fan group 7 is working, the dustproof net 12 can reduce dust passing through the axial flow fan and reduce dust adsorption onto the heat exchanger 2. Since the dustproof net 12 will become clogged after long-term use, the device needs to be replaced regularly after a period of use.
[0026] Reference Figure 1-4 Two air inlet pipes 16 and two air outlet pipes 17 are each fixedly equipped with a three-way pipe 6 on one side. A support rod 8 is fixedly installed in the middle of the bottom surface of the fixing frame 4. Multiple fixing bolts 9 are threaded on the inner walls of the upper and lower ends of the fixing frame 4. A snap-fit block 15 is fixedly installed on the upper and lower ends of the fixing frame 11. A third mounting plate 13 is fixedly installed on the lower part of the rear end face of the fixing frame 11. Multiple threaded holes 14 are opened on the upper end face of the third mounting plate 13.
[0027] Specifically, the heat exchanger 2 has two inlet pipes 16 and two outlet pipes 17 on one side. Each of the two inlet pipes 16 and two outlet pipes 17 is connected to a three-way pipe 6 on one side, facilitating connection between the heat exchanger 2 and other structures. A support rod 8 is fixed to the center of the inner bottom surface of the mounting bracket 4. The support rod 8 reinforces the mounting frame 11 during use, increasing the strength of the mounting bracket 4. The mounting bracket 4 is secured to the first mounting plate 3 and the second mounting plate 5 using fixing bolts 9. (The last sentence appears to be incomplete and possibly refers to an axial flow circuit.) When the fan unit 7 is damaged, the fixing frame 4 can be disassembled by removing the fixing bolts 9, allowing the staff to replace the axial fan unit 7. The upper and lower ends of the fixing frame 11 are fixed with snap-fit blocks 15, allowing the fixing frame 11 to be placed inside the snap-fit groove 10. The lower rear end face of the fixing frame 11 is fixed with a third mounting plate 13. The upper end face of the third mounting plate 13 is provided with multiple threaded holes 14. When in use, bolts can be placed inside the threaded holes 14, so that the fixing frame 11 can be connected to the snap-fit groove 10 at the lower end.
[0028] Working principle: When the device is in use, the heat exchanger 2 is installed inside the fixed box 1. Two air inlet pipes 16 and two air outlet pipes 17 are provided on one side of the heat exchanger 2. One side of each of the two air inlet pipes 16 and the two air outlet pipes 17 is connected to a three-way pipe 6 to facilitate the connection of the heat exchanger 2 with other structures. The rear ends of the first mounting plate 3 and the second mounting plate 5 are both fixed with snap-fit grooves 10. When in use, the snap-fit grooves 10 can snap the fixed frame 11 inside. When in use, the fixed frame 11 is equipped with a dustproof net 12 inside, so that the dustproof net 12 can be placed at the rear end of the axial flow fan unit 7. When the axial flow fan unit 7 is started, the dustproof net 12 can reduce dust passing through the heat exchanger.
[0029] The first mounting plate 3 and the second mounting plate 5 can be fixed by fixing bolts 9 and fixing bracket 4, so that fixing bracket 4 can be kept stable at the rear end of fixing box 1. When in use, fixing bracket 4 can fix two sets of axial flow fans inside. When the axial flow fan set 7 is damaged, fixing bracket 4 can be disassembled by removing fixing bolts 9, so that the staff can replace the axial flow fan set 7.
[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
