[0002] Most of the contemporary buildings are made of reinforced concrete, and the concrete has the characteristic of storing a lot of heat, so the thicker the wall is, the more heat it absorbs and stores. Especially in summer, the wall surface absorbs a large amount of heat from the sun, and the heat still cannot dissipate for a long time at night, so even if the air conditioner is turned on at full capacity, the indoor comfort cannot be quickly restored, which increases the energy consumption.

[0003] In the prior art, a water curtain system is used to cool the wall, or a wall surface water spraying method is used to cool the wall. The water curtain system has certain humidity in the refrigeration process and is not easy to control, and certain noise is generated during operation. If a large amount of water is directly sprayed on the wall surface in the wall surface water spraying method, the wall surface is prone to be damp, which affects the service life. If a spraying method is used, the distribution range of the pipe fittings is large, and the pipe fittings are mostly fixedly arranged on the wall surface, so the flexibility is not high. SUMMARY

[0031] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0032] like Figures 1 to 5 As shown, the present invention provides a building wall cooling device, including an extension mechanism 1, a bending pipe assembly 2, a cooling fan 3, and a pressing pipe mechanism 4.

[0033] Among them, the bending pipe group 2 is a flexible hose, which includes a bending pipe 206 that can be bent back and forth and installed on the wall to be cooled. The inlet 203 and outlet 204 of the bending pipe 206 are connected by a return pipe (not shown in the figure).

[0034] A water injection mechanism (not shown in the figure) is installed at the water inlet 203, and the return water pipe is connected to the heat exchanger (not shown in the figure).

[0035] The extension mechanism 1 includes a fixed mounting plate 101 vertically installed in the middle of the wall to be cooled, and movable mounting plates 102 vertically installed on both sides of the fixed mounting plate 101, which can be slidably arranged horizontally via a power component. Specifically:

[0036] The upper and lower guide rails 103 and 104 are horizontally mounted on the upper and lower ends of the fixed mounting plate 101, respectively. The upper and lower ends of the two movable mounting plates 102 are horizontally slidably disposed between the upper and lower guide rails 103 and 104.

[0037] The power assembly includes a bidirectional lead screw 105 that is horizontally rotatably mounted above the fixed mounting plate 101. One end of the bidirectional lead screw 105 is driven to rotate by a motor 106. The upper ends of the two movable mounting plates 102 are mounted on screws of the bidirectional lead screw 105 with different directions of rotation via lead screw nuts (not shown in the figure).

[0038] The bent tube 206 is reciprocated and disposed between the fixed mounting plate 101 and the movable mounting plate 102. Specifically;

[0039] The bent tubes 206 are two sets disposed between the fixed mounting plates 101 and the movable mounting plates 102 on both sides of the fixed mounting plate 101. Each bent tube 206 includes a horizontal portion 201 installed between the fixed mounting plate 101 and the movable mounting plate 102, and a bent portion 202 installed at the folded-back portion of the adjacent horizontal portion 201. The movable mounting plate 102 has a through hole 107 for sliding through the horizontal portion 201. Preferably, a sleeve 108 that can slide along the through hole 107 is installed on the outside of the bent tube 206 fitted at the through hole 107. The sleeve 108 can reduce wear caused by the bent tube 206 sliding relative to the through hole 107 during the extension and retraction of the device.

[0040] The length of the horizontal part 201 in the horizontal expansion state is greater than the distance between the fixed mounting plate 101 and the moving mounting plate 102 after expansion. Thus, the bending pipe 206 can adapt to the position change in the expansion and contraction state, avoiding the bending pipe 206 being stretched or pressed in the process, thereby shortening the service life.

[0041] The bending part 202 close to the fixed mounting plate 101 is fixedly connected to the fixed mounting plate 101.

[0042] The heat dissipation fan 3 is arranged on the fixed mounting plate 101 and the moving mounting plate 102 for heat dissipation of the gap of the bending pipe 206.

[0043] The heat dissipation gap 207 is left between the upper and lower adjacent horizontal parts 201, and the heat dissipation fan 3 is opposite to the heat dissipation gap 207. The horizontal part 201 of the bending pipe 206 is provided with a water outlet 208 opposite to the heat dissipation gap 207, and the total water amount of the water outlet 208 is always less than the water amount in the diameter of the bending pipe 206. Thus, the bending pipe 206 is in a tensioned state during use.

[0044] The pipe pressing mechanism 4 includes two first upper connecting rods 401 vertically hinged on the two sides of the upper edge of the fixed mounting plate 101 and two first lower connecting rods 402 vertically hinged on the two sides of the lower edge of the fixed mounting plate 101. The upper and lower ends of the moving mounting plate 102 are respectively vertically hinged with a second upper connecting rod 403 and a second lower connecting rod 404. The first upper connecting rod 401 and the second upper connecting rod 403 on the corresponding side are hinged with a downward pressing rod 405 perpendicular to the wall surface, and the first lower connecting rod 402 and the second lower connecting rod 404 on the corresponding side are hinged with an upward pressing rod 406 perpendicular to the wall surface.

[0045] The outer end of the downward pressing rod 405 is vertically downward, and the outer end of the upward pressing rod 406 is vertically upward. The baffle 407 is arranged to avoid the bending pipe 206 from being loose and moving outward in the contraction state of the device.

[0046] The working principle of the device is as follows:

[0047] I. Expansion state:

[0048] The two moving mounting plates 102 driven by the motor 106 on the different rotation direction screw rods of the bidirectional lead screw 105 move away from each other under the guidance of the upper guide rail 103 and the lower guide rail 104.

[0049] The first upper link 401 and the second upper link 403, which are respectively hingedly installed on the upper end of the fixed mounting plate 101 and the movable mounting plate 102, have a tendency to spread horizontally, and in the process, the downward pressing rod 405, which is hingedly installed between the first upper link 401 and the second upper link 403 and is used to limit the upper part of the middle part of the bent pipe 206, gradually moves upward, no longer presses the horizontal part 201 of the bent pipe group 2, and because the distance between the fixed mounting plate 101 and the movable mounting plate 102 gradually increases, the horizontal part 201 of the bent pipe group 2 installed between the two is gradually stretched horizontally. Until the angle between the first upper link 401 and the second upper link 403 is greater than 150° and less than 175°, the motor 106 is turned off.

[0050] Similarly, the horizontal part 201 of the bent pipe group 2, which was previously limited in the middle by the lower downward pressing rod 406, is also gradually spread. Thus, the bent pipe 206 can be relatively evenly distributed on the surface of the wall to be cooled.

[0051] After that, the water injection mechanism is started to inject water into the bent pipe group 2, and the hose bent pipe 206 is lifted by the water to form a water bag that is distributed in a reciprocating spiral on the surface of the wall. On the one hand, the water bag is in relatively uniform contact with the wall and exchanges heat, reducing the temperature of the wall; in addition, the water mist sprayed from the water spraying port 208 of the bent pipe 206 can also have a cooling effect on the wall surface; on the other hand, in cooperation with the heat dissipation fan 3 to dissipate heat in the heat dissipation gap 207, the cooling of the wall can be uniformly and relatively quickly achieved. And in this process, the heated water mist will quickly vaporize, reducing the temperature of the wall without causing the wall to feel wet.

[0052] After the water in the bent pipe 206 exchanges heat with the wall surface, it flows into the return pipe from the water outlet 204 part, and the heated water in the return pipe is cooled when flowing through the heat exchanger part, and then flows into the bent pipe 206 part from the water inlet 203 for reuse. The above process also reduces the waste of water resources.

[0053] In cold winter, hot water is introduced into the bent pipe 206, which also has a heat preservation effect on the wall surface.

[0054] II. Contraction state:

[0055] When the temperature of the wall surface does not need to be processed, the water outlet (not shown in the figure) connected to the bent pipe 206 is opened, and the water in the bent pipe 206 is discharged.

[0056] The two movable mounting plates 102 can be driven by the motor 106 to converge towards the middle part of the fixed mounting plate 101, reducing the wall area occupied when idle. At this time, the pipe pressing mechanism 4 between the fixed mounting plate 101 and the movable mounting plate 102 is contracted.

[0057] The lower pressing rod 405 presses the horizontal part 201 of the bent pipe 206 downwards and the upper pressing rod 406 presses the horizontal part 201 of the bent pipe 206 upwards, so as to bend the horizontal part 201 from the middle part, thereby the whole bent pipe 206 can be accommodated between the fixed mounting plate 101 and the moving mounting plate 102. The residual water in the pipe can be squeezed out from the water outlet part.

[0058] The present application can realize the contraction and expansion of the device according to the cooling demand by the cooperation of the extension mechanism 1, the bent pipe group 2, the heat dissipation fan 3 and the pipe pressing mechanism 4. On one hand, the bent pipe 206 after expansion can be evenly distributed on the surface of the wall by using the device, thereby improving the uniformity of heat dissipation. The bent pipe 206 after contraction can be relatively flat and accommodated under the guidance of the pipe pressing mechanism 4, thereby improving the service life of the pipe and reducing the floor area of the device after accommodation. On the other hand, the present application can use the heat dissipation fan to dissipate heat at the spraying part of the heat dissipation gap 207 of the bent pipe 206 on the basis of using the bent pipe 206 and the wall for heat exchange, thereby reducing the direct penetration of the water mist to the wall, reducing the moisture degree of the wall and improving the heat dissipation efficiency of the device to the wall. Finally, the device has low noise and realizes the recycling of water resources, thereby improving the heat dissipation efficiency of the device to the wall as a whole.

[0059] Although the present application has been described in detail by the general description and specific embodiments above, some modifications or improvements can be made on the basis of the present application, which is obvious to those skilled in the art. Therefore, these modifications or improvements made on the basis of not deviating from the spirit of the present application are within the scope of the present application.
