Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. The applicant emphasizes here that the following embodiments are examples of the technical solutions of the present invention, which can achieve corresponding technical effects and solve corresponding technical problems, and the protection scope of the technical solutions does not include only the following embodiments.

As shown in fig. 1 to 13, the water-cooled fan capable of circulating refrigeration of the present invention mainly includes a housing 1, a water storage box 2, a cooling fan 401, and a cooling core 301. Wherein the water storage box 2 is detachably arranged at the bottom of the shell 1, the cooling fan 401 and the cooling core 301 are fixed in the shell 1, and the positions of the two are corresponding to each other.

The cooling core 301 and the water storage box 2 are both positioned in the shell 1 and are arranged from top to bottom, and the water storage box 2 is also internally provided with a water pump 302. The water storage box 2 can be drawn out from the shell 1, so that the water storage box can be operated by a user such as water adding and cleaning. A pipeline is connected to the water outlet 305 of the water pump 302, and the water in the water storage box 2 is output from the upper part of the cooling core 301 through the guide of the pipeline. And a water return plate 303 is fixed below the cooling core 301 and used for collecting water which cannot be absorbed by the cooling core due to sufficient infiltration. The water return plate 303 is provided with a water return hole 304, and the water return hole 304 is communicated with the water storage box 2. The water in the water storage box 2 is guided above the cooling core 301 by the conveying of the water pump 302 and the guiding of the pipeline, so that the cooling core 301 is prevented from being incapable of being completely soaked due to the gravity action of the water in the absorption process.

In order to further realize the cooling of water in the water storage box 2 and improve the cooling effect of the water cooling fan on the indoor hot air, a refrigeration assembly is further arranged on the pipeline of the water pump 302. Because the water-cooling fan has the cooling effect of water, the requirement of the refrigerating capacity of the refrigerating assembly is not high, but how to effectively reduce the water temperature of the cooling core 301 during working under the conditions of low power consumption and small refrigerating capacity is the key of the setting of the refrigerating assembly. The refrigeration assembly mainly comprises a refrigeration box 307, a semiconductor refrigeration piece 308 and a radiating fin 309, wherein the semiconductor refrigeration piece 308 is fixed in the refrigeration box 307, a water outlet 305 and a water inlet 306 are respectively arranged at two ends of the refrigeration box 307, and the water inlet 306 is communicated with a water pump 302 pipeline. The water flow enters the refrigeration box 307 from the water inlet 306 by the transmission of the water pump 302, and exchanges heat with the semiconductor refrigeration piece 308 and then is output through the water outlet 305. The heat sink 309 is fixedly disposed above the semiconductor chilling plate 308, and is used for reducing a temperature difference between the cold end and the hot end of the semiconductor chilling plate 308 to ensure that the semiconductor chilling plate 308 works normally. In fact, in order to avoid the splash phenomenon caused by the excessively high flow rate of the water flow outputted from the water outlet 305, the water diversion table 319 is provided at the lower portion of the water outlet 305, and the water diversion table 319 and the water outlet 305 are integrally formed.

Since the refrigerating capacity cannot be too large when the refrigerating assembly is in operation, or the heating capacity is increased, the larger the contact area between the water flow in the refrigerating box 307 and the semiconductor refrigerating sheet 308 is, the longer the contact time is, and the higher the utilization efficiency of the cold energy is. The semiconductor refrigeration piece 308 of the invention adopts a fin-shaped structure with staggered heights, the refrigeration box 307 is internally provided with the connecting groove 313, the connecting groove 313 and the refrigeration box 307 are integrally processed and molded, and the semiconductor refrigeration piece 308 is used for fixing the semiconductor refrigeration piece 308, so that the structural stability of the semiconductor refrigeration piece 308 in the refrigeration box 307 is improved, and the smooth heat exchange between water flow and the semiconductor refrigeration piece 308 can be ensured. The connecting slots 313 are arranged in a zigzag pattern so that a serpentine water channel is formed in the cooling box 307, increasing the contact area between the water flow and the semiconductor cooling fins 308. The bottom of the coupling groove 313 is provided with a water passage groove 314, and the water passage groove 314 is formed in a downwardly concave shape, which allows the water flowing through the refrigeration cassette 307 to pass therethrough. In addition, a sealing ring 318 is arranged at the contact part of the refrigeration box 307 and the semiconductor refrigeration piece 308 to ensure that the water flow does not overflow.

In the invention, a water distribution disc 310 is fixed below a water outlet 305 of a refrigeration box 307, a plurality of water outlet holes 311 are formed in the water distribution disc 310, and the water outlet holes 311 are positioned above a cooling core 301 and are uniformly distributed in the water distribution disc 310. The water distribution disc 310 is arranged to enable water flow to be uniformly distributed and dropped onto the upper surface of the cooling core 301 after the water flow comes out of the refrigeration box 307, so that cold water continuously permeates and soaks downwards in the cooling core 301 under the action of gravity. In order to further improve the uniformity of water output in the water diversion disc 310, a water guide platform 312 can be fixedly arranged at the bottom of the water diversion disc 310, and the water guide platform 312 and the water diversion disc 310 are integrally formed and communicated with the water outlet hole 311. When water flows out through the outlet holes 311 by the surface tension of the water, water drops adhere to the water diversion table 319. When the amount of water in the knock out tray 310 reaches the upper limit of gravity, the water droplets will leave the knock out table 319 against the surface tension and drip onto the cooling core 301. The structure can further ensure the uniform dripping of water drops on the upper surface of the cooling core 301, ensure the uniform distribution of water flow in the cooling core 301 and improve the uniformity and stability of the water flow to the passing hot air cooling. Because the water flow drops from the water diversion disc 310 to the cooling core 301, in order to prevent cold water from splashing out of the cooling core 301, the cooling core 301 is fixedly provided with a water blocking block 315, and the water blocking block 315 and the cooling core 301 are processed in an integrated forming mode and correspond to the water diversion disc 310.

In addition, because the water flow power of the invention is the water pump 302, in order to avoid the water pump 302 from having too high power and causing the water flow speed to be too fast, the refrigeration effect of the refrigeration component is reduced, the pipeline of the water pump 302 is provided with a pressure relief opening 316 positioned in the water storage box 2, and the pressure relief opening 316 is transversely arranged. The water blocking piece 317 is fixedly arranged in the water storage box 2, the water blocking piece 317 corresponds to the pressure relief opening 316 in position and has a small distance with the pressure relief opening 316, the structure avoids the noise caused by the overhigh water flow speed of the pressure relief opening 316, and the silencing effect of the water cooling fan during working is improved.

The outer casing 1 of the present invention is further provided with an inner casing 4, the cooling core 301 and the cooling fan 401 are fixedly connected to the inner casing 4, and the inner casing 4 is fixed with the outer casing 1. The housing 1 is provided with an air outlet 402 and an air inlet 403, and the air outlet 402 and the air inlet 403 correspond to the cooling core 301 and the cooling fan 401 respectively. When the water cooling fan works, the cooling fan 401 pumps external hot air into the cooling core 301, and the hot air generates heat exchange and cools when the cooling core 301 soaked by cold water passes through, and then is output to the outside through the air outlet 402. Because the overall temperature of the cooling core 301 is lower when the cooling core is soaked in cold water, heat exchange is generated between the cooling core and the outside, and the phenomenon of cold energy dissipation is caused. In the present invention, the outer casing 1 and the inner casing 4 are separated from each other, and a gap between the two forms a return air channel 405 to store cold energy dissipated from the cooling core 301 to the surface of the inner casing 4. Since the air itself has a low thermal conductivity, further dissipation of cold energy to the surface of the housing 1 via thermal conduction is prevented. A return air inlet 404 is formed in the casing 1, and a return air passage 405 is communicated with the return air inlet 404 and the side where the cooling fan 401 supplies air. When the cooling fan 401 works, negative pressure is generated at the outer side of the cooling fan, air outside the air return opening 404 flows to the cooling fan 401 through the air return channel 405 due to the influence of the negative pressure, and cold energy dissipated on the surface of the inner shell 4 flows to the cooling fan 401 through the air return channel 405 together, so that the recovery of the dissipated cold energy is realized. In fact, in order to make the recovery of the dissipated cold energy more complete, the return air inlet 404 may be provided at a side of the outer casing 1 corresponding to the cooling fan 401, so that the return air passage 405 may encompass the entire side of the inner casing 4.

In the present invention, since the inner casing 4 is fixed in the outer casing 1, when the air flow is generated in the air return channel 405, the air flow cooled at the air outlet 402 is also pulled by the air flow, so that the air output of the air outlet 402 is reduced. To prevent this, a vertical baffle 406 is provided on the inner case 4, which is located at one side of the air outlet 402 and is connected to the inner wall of the outer case 1. In addition, an air return frame 407 is disposed on the inner casing 4, and the air return frame 407 is located between the cooling fan 401 and the air inlet 403 and can communicate the air return channel 405 and the cooling fan 401. The air return frame 407 is disposed to form a gap between the air inlet 403 and the cooling fan 401, so that a negative pressure space is formed outside the cooling fan 401 during operation, and the communication between the negative pressure space and the air return channel 405 causes air outside the air return inlet 404 to continuously receive a negative pressure pulling force to flow to the cooling fan 401 through the air return channel 405, thereby bringing cold energy dissipated on the surface of the inner casing 4 into the cooling fan 401.

In order to form a one-way flow passage for the return air duct 405, a transverse baffle 408 is fixed to the return air frame 407. Through the separation effect of horizontal baffling board 408, prevent that the air of casing top from getting into cooling fan 401, ensure that the air current of return air passageway 405 is not influenced to realize the effective recovery of cold energy. The vertical flow baffle 406 and the horizontal flow baffle 408 are formed integrally with the inner casing 4, which improves the connection stability between the vertical flow baffle 406 and the inner casing 4, and improves the sealing performance between the vertical flow baffle 406 and the inner casing and the air return channel 405.

The interior of the water storage box 2 is divided into a cold water cavity 21 and a normal temperature water cavity 22, and the cold water cavity 21 and the normal temperature water cavity 22 are divided and isolated through a heat insulation wall. Be provided with the gib block 27 on the water storage box 2 outer wall, this gib block 27 matches with the shell 1 inner wall and is connected, and the setting of gib block 27 can make things convenient for operating personnel to peg graft smoothly in shell 1 bottom after adding water in water storage box 2 to avoid obscuring of cold water chamber 21 and normal atmospheric temperature water chamber 22 position. The cold water cavity 21 is communicated with a water cooling component of the water cooling fan, the cold water cavity is used for directly supplying water for normal work of the water cooling fan, and return water of the water cooling fan directly enters the cold water cavity 21. The cold water chamber 21 can be filled with a refrigerant such as an ice bag or ice cubes, or the water in the cold water chamber 21 can be refrigerated by a refrigerating part. The heat insulating wall is provided with a connecting wall 23, and a water replenishing hole 24 is formed at the lower part of the connecting wall 23. The water replenishing hole 24 is communicated with the cold water cavity 21 and the normal temperature water cavity 22, and is used for introducing normal temperature water from the normal temperature water cavity 22 into the cold water cavity 21 when the water amount of the cold water cavity 21 is reduced, and keeping the liquid levels of the cold water cavity 21 and the normal temperature water cavity 22 balanced. In fact, because the water in the cold water cavity 21 continuously enters the water cooling assembly, the liquid level in the cold water cavity 21 is always lower than the normal temperature water cavity 22 when the water cooling fan works, and the cold water in the cold water cavity 21 is prevented from entering the normal temperature water cavity 22 to cause the outflow of cold energy.

In order to further realize the centralized utilization of cold energy and reduce the large loss of the cold energy caused by heat exchange with the outside in the working process of the water cooling fan, the volume of the cold water cavity 21 is set to be smaller than that of the normal temperature water cavity 22. The structure of the heat insulation wall mainly comprises a wall body 25 and a heat insulation cavity 26, wherein the heat insulation cavity 26 is arranged in the wall body 25 and is communicated with the outside air. The structure realizes effective isolation of cold energy in the cold water cavity 21 and the normal temperature water cavity 22 by utilizing the principle that the thermal conductivity of air is far lower than that of water. Meanwhile, due to the adoption of the hollow heat insulation structure, the heat insulation wall and the water storage box 2 can be integrally formed for processing, the sealing and isolating effect between the cold water cavity 21 and the normal-temperature water cavity 22 is enhanced, and the loss of the cold energy in the cold water cavity 21 is further reduced. In addition, the side part of the cold water cavity 21 is also provided with a backflow table 28, and the backflow table 28 can prevent water in the water cooling fan from generating dripping sound during backflow, so that the silencing effect of the water cooling fan during working is improved.

In order to realize the control function, the power on-off switch 103 can be connected in series with the external power supply and the circuit of the water-cooling fan circuit controller.

In the invention, the magnetic attraction component mainly comprises an installation seat 104, a fixed seat 105, a magnetic conductive sheet 106 and a magnet 107.

When the water-cooling fan works, a user firstly adds water into the water storage box 2, and the water pump 302 pumps the water in the cold water cavity 21 of the water storage box 2 and conveys the water to the refrigeration component. After the water flows through the refrigeration assembly and is cooled, the water is output from the water outlet 305 of the refrigeration box 307 to the water diversion disc 310. Under the action of the gravity and the surface tension of the water, the water is uniformly distributed in the water distribution disc 210 and flows out through the water outlet holes 311, and then drops onto the cooling core 301. The water continuously permeates and soaks downwards on the cooling core 301 through gravity, and exchanges heat with the hot air pumped by the cooling fan 401 in the cooling core 301 to reduce the temperature of the hot air. Finally, the cooled air flow is blown out of the outside through the door body 101, so that the indoor temperature is reduced.
