Description

Technical Field

[0001] The utility model relates to the field of cooling devices, in particular to a high-efficiency and energy-saving direct cooling type cooling device. Background Art

[0002] With the development of industry and urbanization in my country, the contradiction between the rapid increase in water consumption and the relative scarcity of water resources, as well as the wastewater and mist generated by the heat exchange process, have put great pressure on environmental protection. Various types of cooling towers and cooling technologies are one direction for saving water, reducing emissions, reducing noise and protecting the environment.

[0003] A cooling tower is a device that uses water as a circulating coolant, absorbing heat from the system and discharging it into the atmosphere, thereby lowering the air temperature inside the tower. This allows for the recycling of cooling water and is widely used in air conditioning cooling systems and industrial water cooling.

[0004] At present, the traditional mechanical fan high-density filler cooling tower is widely used in the market and has developed rapidly. Various structural forms of cooling towers have emerged. However, from the perspective of long-term operation, the mechanical tower has high energy consumption and loud noise, and the filler is prone to aging, scaling, and high resistance. Once the filler scales, the cooling effect is difficult to guarantee.

[0005] Later, a type of EC fan exhaust closed cross flow cooling tower appeared on the market, such as CN The bottom of the two sides of the cooling tower body is fixedly connected with a receiving plate by bolts, and the upper end of the water pump mounting seat is provided with a water pump; the cleaning nozzle can be used to flush the air guide plate when the cooling tower is in use, thereby reducing the accumulation of dust on the air guide plate, and the cleaning nozzle can be used to clean the air guide plate more conveniently and quickly during operation, thereby reducing the need for regular maintenance and cleaning of the air guide plate, making the cooling tower more convenient to use; the cleaning nozzle can be used to clean the air guide plate more conveniently and quickly during operation, thereby reducing the need for regular maintenance and cleaning of the air guide plate, making the cooling tower more convenient to use; but this exhaust type cooling tower has the following defects:

[0006] For example, the fan cooling method of this type of cooling tower is the exhaust method. During cooling, it is usually static cooling, so the cooling is from the outside to the inside, which not only reduces the cooling speed, but also consumes a lot of electricity and the cooling tower cooling efficiency cost is high.

[0007] Therefore, it is necessary to study a new technical solution to solve the above problems. Utility Model Content

[0008] In view of this, the present invention aims to address the deficiencies in the existing technology, and its main purpose is to provide a high-efficiency and energy-saving direct cooling device. Through the structural design and coordination between the cooling tower, the water collector, the first adjustable speed fan and the nozzle assembly, it effectively solves the problems in traditional technology where the cooling tower uses the exhaust method, resulting in low cooling speed, high power consumption and high cooling tower cooling efficiency cost.

[0009] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0010] A high-efficiency and energy-saving direct cooling device comprises a cooling tower, a water collector, a first adjustable-speed fan and a nozzle assembly;

[0011] The cooling tower has a water inlet, an air outlet and a cooling chamber; the water collector is used to separate water and air; the water collector is arranged in the cooling chamber to form a first chamber and a second chamber; the water inlet is connected to the first chamber; the air outlet is connected to the second chamber; the first adjustable speed fan is arranged on the cooling tower, and the air outlet end of the first adjustable speed fan is connected to the first chamber and is opposite to one side of the water collector; the nozzle assembly is arranged in the first chamber and is located on the bottom end surface of the first chamber.

[0012] As a preferred solution, the cooling tower is further provided with a controller, and the controller is electrically connected to the first adjustable speed fan.

[0013] As a preferred solution, a temperature sensor is further provided in the first chamber, and the temperature sensor is electrically connected to the controller.

[0014] As a preferred solution, the nozzle assembly includes a connecting pipe and several vortex nozzles; the input end of the connecting pipe is connected to the output end of the water inlet; the several vortex nozzles are arranged on the connecting pipe at intervals and are all connected to the output end of the connecting pipe.

[0015] As a preferred solution, a baffle is provided on the side of the first chamber close to the water collector, and a water storage chamber is formed between the side of the baffle close to the water collector and the side of the water collector; a water storage tank is also provided on the cooling tower, and the water storage tank is connected to the water storage chamber.

[0016] As a preferred solution, a water pump is further provided on a side of the cooling tower close to the water tank, and an input end of the water pump is connected to the water tank through a water pipe.

[0017] As a preferred solution, a second adjustable-speed fan is further provided at the air outlet for discharging hot air out of the cooling chamber, and the second adjustable-speed fan is electrically connected to the controller.

[0018] As a preferred solution, the cooling tower includes a left side panel, a right side panel, an upper side panel, a lower side panel, a front side panel and a rear side panel, the upper and lower ends of the left side panel and the right side panel are respectively connected to the upper side panel and the lower side panel; the front and rear ends of the left side panel and the right side panel are respectively connected to the front side panel and the rear side panel to form a cooling chamber.

[0021] Compared with the prior art, the utility model has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solution that it mainly realizes the structural design and coordination between the cooling tower, the water collector, the first adjustable-speed fan and the nozzle assembly. When in use, the nozzle assembly sprays from low to high in the shape of a rotating atomization, thereby increasing its contact area with the wind and greatly increasing the cooling effect. At the same time, in conjunction with the direct-blowing cooling method of the first adjustable-speed fan, the direct-blowing wind and water collide and contact more fully to produce rich bubble water, thereby cooling the heat and humidity in the room. The hot air in the water ball is blown away, making the cooling effect better, cooling faster and saving electricity and energy consumption; secondly, the water falls from high to low, giving the wind and water more time to collide and mix, thereby extending the cooling time of the cooling water in the cooling chamber; on the other hand, the hot water sprayed out from the nozzle assembly is blown on the water collector in a scattered form under the blowing of the first adjustable speed fan. The bubble water ball directly collides with the water collector to achieve a barrier effect, and the water and wind are instantly separated. The water flows downward and the hot air floats upward, so that the water collector can fully absorb the heat, thereby improving the cooling effect.

The water collector 20 can be a swirl plate water collector or a folding plate water collector or a folding plate water collector.

[0042] Preferably, a baffle 14 is provided on the side of the first chamber 131 close to the water collector 20, and a water storage chamber 141 is formed between the side of the baffle 14 close to the water collector 20 and the side of the water collector 20; a water storage tank 15 is also provided on the cooling tower 10, and the water storage tank 15 is connected to the water storage chamber 141.

[0043] Preferably, a water pump 16 is further provided on the side of the cooling tower 10 close to the water tank 15.

After the cooling effect is completed, the cooled water is stored in the water tank 15, and then the water pump 16 supplies water to the workshop or production equipment for recycling.

[0044] Preferably, the nozzle assembly 40 includes a connecting pipe 41 and a plurality of vortex nozzles 42; the input end of the connecting pipe 41 is connected to the output end of the water inlet 11; the plurality of vortex nozzles 42 are spaced apart on the connecting pipe 41 and are all connected to the output end of the connecting pipe 41.

[0047] Since the cooling tower 10 is a closed design with a square structure, it fully utilizes fluid mechanics and aeolian mechanics. The mixture of water and air produces rich water vapor bags, which take away heat faster and more. There is no physical contact with sunlight, other impurities, and other sediment pollution, which greatly protects the cooling water. The water quality is also protected, and there is no occurrence of moss or algae, so the water quality is guaranteed.

[0048] The general working principle of this embodiment is described in detail below:

[0049] During use, hot water or warm water enters the connecting pipe 41 through the inlet, and then the nozzle of the nozzle assembly 40 sprays the hot water or warm water in the connecting pipe 41 from low to high in the shape of a rotating atomization to form a shower mist, which is sprayed in the closed first chamber 131 space. Then, in conjunction with the direct-blowing cooling method of the first adjustable-speed fan 30, the direct-blowing wind directly contacts the water in the first chamber 131, collides and mixes to form a steam drum state, thereby blowing away the hot air of the hot and wet water ball in the cooling chamber 13. Due to the mixing of wind and water, direct blowing will produce more water vapor and steam drums, and finally the air and the warm and wet water ball will be further separated after being blocked and collided by the water collector 20, and the water will flow downward and then be exhausted through the second adjustable-speed fan 70.

[0050] The key design features of the present invention lie primarily in the structural design and coordination between the cooling tower, the water collector, the first adjustable-speed fan, and the nozzle assembly. During operation, the nozzle assembly sprays water from a low-to-high position, creating a rotating atomized pattern. This increases the contact area with the air and significantly enhances the cooling effect. Furthermore, the first adjustable-speed fan utilizes direct-blowing cooling, allowing the direct-blowing air and water to more fully collide and interact, producing abundant bubbles, which remove the heat from the hot, wet water spheres within the cooling chamber. This results in better cooling, faster cooling, and energy savings. Furthermore, the water falls from a high position to a low position, allowing the air and water to collide and mix more frequently, thereby extending the cooling time of the cooling water within the cooling chamber. Furthermore, the hot water sprayed from the nozzle assembly, driven by the first adjustable-speed fan, is dispersed onto the water collector. The bubbles directly collide with the water collector, creating a barrier effect that instantly separates the water and air, allowing the water to flow downward and the hot air to float upward. This allows the water collector to fully absorb heat, thereby enhancing the cooling effect.

[0051] The above description is merely a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
