Description

Technical Field

[0001] This utility model relates to the field of building energy-saving equipment technology, specifically a green building surface cooling device. Background Technology

[0002] With increasing emphasis on environmental protection and energy conservation, the development of green buildings is receiving more and more attention. In summer, the temperature of building surfaces rises due to solar radiation, which not only increases the load on the building's internal air conditioning system, causing energy waste, but also exacerbates the urban heat island effect.

[0003] The existing patent document CN220338741U discloses a surface cooling device for green buildings. This utility model drives the output shaft of the drive motor to drive the adjustment component to rotate synchronously, thereby adjusting the angle of the rotating frame, so that the blowing component can face the exterior wall of the green building, realize water mist diffusion, fully cover the exterior wall of the green building, and improve cooling efficiency.

[0004] However, existing green building surface cooling devices, which use motor-driven adjustment components to rotate the frame to achieve water mist coverage cooling, have obvious defects. They rely on mechanical transmission, which consumes a lot of energy, has a complex and easily damaged structure, and has high maintenance costs and usage risks. The water mist cannot be recovered after evaporation, resulting in serious waste of water resources. Moreover, relying solely on physical cooling, they lack solar radiation blocking methods, making it difficult to maintain stable temperature control under high temperature and strong sunlight. The cooling efficiency and energy-saving effect are both insufficient to meet the requirements of green buildings. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] The purpose of this utility model is to provide a green building surface cooling device to solve the problems of high energy consumption, high maintenance costs, water waste and insufficient cooling efficiency of existing green building surface cooling devices mentioned in the background art.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a green building surface cooling device, including a building exterior wall, wherein a cooling plate is attached to the outer surface of the building exterior wall, and the other side of the cooling plate is a wavy cooling surface, wherein the wavy cooling surface has multiple protrusions and depressions, the protrusions and depressions are alternately arranged, and the surface of the wavy cooling surface is coated with a nano titanium dioxide coating.

[0009] Furthermore, a water inlet pipe is provided above the cooling plate, a distributor is provided at the bottom end of the water inlet pipe, and multiple channel inlets are provided on the upper surface of the cooling plate. Each distributor outlet of the distributor is connected to a channel inlet.

[0010] Furthermore, the cooling plate has several interconnected cooling channels inside, and the channel inlets are connected to the cooling channels.

[0011] Furthermore, the bottom end of the cooling plate is provided with multiple channel outlets, which are connected to the cooling channels.

[0012] Furthermore, a drain pipe is connected to the outlet of the channel, and a water collection tank is provided on the outer surface of the building exterior wall below the cooling plate. The end of the drain pipe away from the cooling plate is connected to the water collection tank.

[0013] Furthermore, a water pump is fixedly installed on one side of the water collection tank, and a water supply pipe is connected to the outlet end of the water pump. An aluminum heat sink is provided on the corrugated cooling surface.

[0014] Furthermore, the aluminum heat sink is tightly fitted to the outer wall of the cooling channel, and multiple evenly distributed solar cooling fans are arranged on the outer side of the aluminum heat sink on the wavy cooling surface.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This green building surface cooling device innovatively adopts a biomimetic wave-shaped cooling surface structure. Through the alternating arrangement of protrusions and depressions, the cooling area is increased compared to the traditional planar structure, which greatly enhances the heat exchange efficiency with the outside air. At the same time, the nano-titanium dioxide intelligent coating on the cooling surface uses the photocatalytic principle to achieve a solar radiation reflectivity of more than 90%, forming a dual protection system of "passive heat insulation + active heat dissipation". This effectively blocks the external heat from entering the building, significantly reduces the operating load of the air conditioning system, and truly achieves energy conservation and consumption reduction in buildings.

[0017] 2. This green building surface cooling device achieves the recycling of cooling water through a water circulation system consisting of an inlet pipe, a distributor, cooling channels, a drain pipe, and a water collection tank. The distributor can evenly distribute the water flow to each cooling channel to ensure uniform cooling of the cooling plate. The water collection tank, in conjunction with the water pump, collects the used water and transports it to the circulation system, reducing water waste and conforming to the concept of green building environmental protection and energy conservation.

[0018] 3. This green building surface cooling device, through the close fit between aluminum heat sinks and cooling channels, can quickly conduct heat from the water in the cooling channels. Combined with the solar cooling fan on the wave-shaped cooling surface, it forces the airflow speed to accelerate, forming efficient convection heat dissipation, further improving heat dissipation efficiency. Moreover, the solar fan uses clean energy to power the device, reducing the device's operating energy consumption and improving energy utilization efficiency. Attached Figure Description

[0025] 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.

[0026] Please see Figure 1 - Figure 5 This utility model provides a technical solution: a green building surface cooling device, including a building exterior wall 1, a cooling plate 2 attached to the outer surface of the building exterior wall 1, and a wave-shaped cooling surface 3 on the other side of the cooling plate 2. The wave-shaped cooling surface 3 has multiple protrusions and depressions, which are alternately arranged. The surface of the wave-shaped cooling surface 3 is coated with a nano-titanium dioxide coating 4.

[0027] A water inlet pipe 5 is installed above the cooling plate 2, and a distributor 6 is installed at the bottom of the water inlet pipe 5. Multiple channel inlets 7 are installed on the upper surface of the cooling plate 2. Each distributor outlet of the distributor 6 is connected to a channel inlet 7. Several interconnected cooling channels 8 are provided inside the cooling plate 2. The channel inlets 7 are connected to the cooling channels 8. Multiple channel outlets 9 are provided at the bottom of the cooling plate 2. The channel outlets 9 are connected to the cooling channels 8. A drain pipe 10 is connected to the channel outlets 9. A water collection tank 11 is installed on the outer surface of the building exterior wall 1 below the cooling plate 2. The end of the drain pipe 10 away from the cooling plate 2 is connected to the water collection tank 11. A water pump 12 is fixedly installed on one side of the water collection tank 11. The outlet end of the water pump 12 is connected to a water supply pipe 13. An aluminum heat sink 14 is installed on the corrugated cooling surface 3. The aluminum heat sink 14 is tightly attached to the outer wall of the cooling channel 8. Multiple evenly distributed solar cooling fans 15 are installed on the outer side of the aluminum heat sink 14 on the corrugated cooling surface 3.

[0028] Working Principle: When the device is working, external water flows into the distributor 6 through the inlet pipe 5. The distributor 6 evenly distributes the water flow to multiple channel inlets 7 on the upper surface of the cooling plate 2. The water then enters the interconnected cooling channels 8 inside the cooling plate 2. Inside the cooling channels 8, the water flows through the wall of the cooling plate 2 and exchanges heat with the corrugated cooling surface 3, absorbing the heat conducted by the building's exterior wall 1 and the heat absorbed by the corrugated cooling surface 3 from the outside. The corrugated cooling surface 3, with its alternating convex and concave structure, significantly increases the contact area with the air. The nano-titanium dioxide coating 4 on the surface utilizes high reflectivity to reduce the absorption of solar radiation by the corrugated cooling surface 3. At the same time, the aluminum heat sink is tightly attached to the outer wall of the cooling channel 8. The aluminum heat sink 14 quickly transfers the heat from the hot water in the cooling channel 8 to itself. The solar cooling fan 15, installed on the outside of the aluminum heat sink 14, operates, accelerating airflow and forcing convection to remove the heat from the aluminum heat sink 14, further improving heat dissipation efficiency. After heat exchange, the water flows from the channel outlet 9 at the bottom of the cooling plate 2 through the drain pipe 10 into the water collection tank 11. The water pump 12 in the water collection tank 11 transports the collected water to the external water circulation system through the water supply pipe 13. After treatment, the water flows back into the cooling channel 8 through the water inlet pipe 5, realizing the recycling of cooling water. The whole process does not require complex mechanical transmission. By using solar energy to drive the fan and recycle water, the temperature of the building's exterior wall 1 is efficiently reduced, achieving the goal of green energy saving.
