Abstract
Description
Technical Field
[0001] This utility model relates to the field of steam cooler technology, and in particular to an evaporative cooler with an anti-icing device. Background Technology
[0002] An evaporative cooler is a device that cools a liquid by utilizing the latent heat absorbed by water during evaporation. In existing technology, evaporative coolers are generally box-shaped structures with a fan, spray system, and multiple cooling pipes inside. When the evaporative cooler is working, the fan carries away water vapor from the box, causing the cooling water sprayed onto the cooling pipes to evaporate rapidly, thus cooling the liquid inside the pipes. The multiple cooling pipes are arranged in a specific shape, and ventilation windows with multiple louvers are located on opposite sides of the box. These louvers primarily prevent water from splashing out of the tower. Furthermore, the louvers also serve as air guides, guiding the cold air outside the box to convectively exchange heat with the cooling water inside, thereby lowering the temperature inside the cooling box. The spray system inside the box sprays cooling water in a mist form, which exchanges heat with the cold air through the spray packing material, further achieving the cooling effect.
[0003] When the spray system sprays water, some of it splashes onto the inner wall of the cooler housing. The water on the inner wall then slides down the inner wall onto the louvers of the ventilation windows. Especially in the cold winters of northern China, this causes ice to form on the louvers. Over time, this ice buildup creates an ice wall that blocks the ventilation windows, preventing cold air from entering the cooler. Consequently, the hot water in the cooling pipes cannot exchange heat with the cold air, reducing the heat exchange efficiency of the hot water in the cooling pipes and preventing the cooler housing from cooling down. In northern winters, de-icing the louvers is usually done manually, which increases safety hazards, damages the equipment, and raises maintenance costs. Utility Model Content
[0004] The main objective of this invention is to provide an evaporative cooler with an anti-icing device, which can effectively solve the problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] An evaporative cooler with an anti-icing device includes a housing, inside which a condenser tube is installed. A left auxiliary tube and a right auxiliary tube are arranged sequentially from left to right on the condenser tube. The ends of the left and right auxiliary tubes away from the condenser tube are fixedly connected to a manifold. Control valves are fixedly connected to the outer surfaces of the left and right auxiliary tubes.
[0007] Preferably, storage slots are provided on both sides of the box body, an electric push rod is fixedly connected to the inner top wall of the storage slot, and a louver is fixedly connected to the bottom end of the electric push rod.
[0008] Preferably, a mounting bracket is fixedly connected to the inner wall of the housing, and a lower arc-shaped tube is fixedly connected to the mounting bracket. An upper arc-shaped tube is hinged to the upper surface of the lower arc-shaped tube, and the upper and lower arc-shaped tubes are connected by locking bolts.
[0009] Preferably, dustproof nets are fixedly connected to both sides of the box body by bolts.
[0010] Preferably, a fan is fixedly connected to the upper surface of the housing, and the number of fans is two.
[0011] Preferably, two support bases are fixedly connected to both sides of the lower surface of the box body, and the support bases are made of stainless steel.
[0012] Preferably, a drain pipe is fixedly connected to the outer surface of the manifold, and the drain pipe passes through the bottom of the box and extends below it.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] 1. This evaporative cooler with an anti-icing device is designed with a coordinated structure of the housing, condenser tubes, left auxiliary tubes, right auxiliary tubes, manifold, control valve, and drain pipe. When the external environment is cold, the operator can open the control valve. As hot gas passes through the condenser tubes, some of the hot gas will flow along the left and right auxiliary tubes. Furthermore, the left and right auxiliary tubes are located inside the louvers. The flowing hot gas can heat the space at the louver location, effectively preventing icing and allowing the cooler to operate normally without subsequent manual intervention, thus saving maintenance costs.
[0015] 2. When the ambient temperature is high, the operator closes the control valve of the evaporative cooler equipped with an anti-icing device to prevent hot gas from the condenser from flowing into the left and right auxiliary pipes.

[0026] 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.
[0027] Example 1
[0028] like Figure 1-9As shown, an evaporative cooler with an anti-icing device includes a housing 1. A condenser pipe 2 is installed inside the housing 1. A left auxiliary pipe 3 and a right auxiliary pipe 4 are arranged on the condenser pipe 2 from left to right. The ends of the left auxiliary pipe 3 and the right auxiliary pipe 4 away from the condenser pipe 2 are fixedly connected to a manifold 5. A control valve 6 is fixedly connected to the outer surface of the left auxiliary pipe 3 and the right auxiliary pipe 4.
[0029] In practical use, through the coordinated arrangement of the housing 1, condenser pipe 2, left auxiliary pipe 3, right auxiliary pipe 4, manifold 5, control valve 6, and drain pipe 16, when the external environment is cold, the operator can open the control valve 6. When hot gas passes through the condenser pipe 2, some of the hot gas will flow along the left auxiliary pipe 3 and right auxiliary pipe 4. Furthermore, the left auxiliary pipe 3 and right auxiliary pipe 4 are also located inside the louvers 9. The flowing hot gas can heat the space at the location of the louvers 9, effectively preventing the probability of icing and allowing the cooler to work normally without subsequent manual handling, saving maintenance costs. When the external ambient temperature is high, the operator closes the control valve 6 to prevent the hot gas from the condenser pipe 2 from flowing into the left auxiliary pipe 3 and right auxiliary pipe 4, and activates the electric push rod 8. The electric push rod 8 drives the louvers 9 to move upward, retracting the louvers 9 into the storage slot 7, increasing the ventilation volume and improving the cooling effect.
[0030] In this embodiment, storage slots 7 are provided on both sides of the box body 1. An electric push rod 8 is fixedly connected to the inner top wall of the storage slot 7, and a louver 9 is fixedly connected to the bottom end of the electric push rod 8.
[0031] In practical use, with the setting of storage slot 7, electric push rod 8 and louver 9, when the temperature is high, the louver 9 can be retracted into the storage slot 7. Since there is no louver 9 to block the air, the air intake can be increased and the ventilation effect is better.
[0032] In this embodiment, a mounting bracket 10 is fixedly connected to the inner wall of the housing 1, and a lower arc-shaped tube 11 is fixedly connected to the mounting bracket 10. An upper arc-shaped tube 12 is hinged to the upper surface of the lower arc-shaped tube 11, and the upper arc-shaped tube 12 and the lower arc-shaped tube 11 are connected by locking bolts.
[0033] In practical use, by installing the bracket 10, the lower arc-shaped tube 11 and the upper arc-shaped tube 12, the condenser tube 2 can be placed on the lower arc-shaped tube 11, and then the upper arc-shaped tube 12 is used to clamp and fix the condenser tube 2, making the condenser tube 2 more stable.
[0034] In this embodiment, dustproof nets 13 are fixedly connected to both sides of the box 1 by bolts.
[0035] In practical use, the dustproof net 13 can effectively reduce the entry of external dust and keep the inside of the box 1 clean.
[0036] In this embodiment, a fan 14 is fixedly connected to the upper surface of the housing 1, and there are two fans 14.
[0037] In practical use, the fan 14 blows air onto the condenser tube 2 to lower its temperature, causing the gas inside the condenser tube 2 to turn into liquid.
[0038] In this embodiment, two support bases 15 are fixedly connected to both sides of the lower surface of the box 1. The support bases 15 are made of stainless steel. A drain pipe 16 is fixedly connected to the outer surface of the manifold 5. The drain pipe 16 passes through the bottom of the box 1 and extends below it.
[0039] In practical use, the support base 15 makes the box 1 more stable. The water that has condensed in the left auxiliary pipe 3 and the right auxiliary pipe 4 can be drained through the manifold 5 and the drain pipe 16.
[0040] Working principle: When the external environment is cold, the operator can open the control valve 6. When hot gas passes through the condenser pipe 2, some of the hot gas will flow along the left auxiliary pipe 3 and the right auxiliary pipe 4. The left auxiliary pipe 3 and the right auxiliary pipe 4 are also located inside the louver 9. The flowing hot gas can heat the space at the location of the louver 9 and prevent the louver 9 from freezing. When the external temperature is high, the operator closes the control valve 6 to prevent the hot gas from the condenser pipe 2 from flowing into the left auxiliary pipe 3 and the right auxiliary pipe 4, and starts the electric push rod 8. The electric push rod 8 drives the louver 9 to move upward and retract the louver 9 into the storage groove 7, thereby increasing the ventilation volume.
