Description

Technical Field

[0001] This application relates to the field of cooling equipment for outdoor construction in summer, and particularly to a cooling device using a ground source heat pump buried pipe. Background Art

[0002] During the construction process of a ground source heat pump air conditioning system, a large number of buried pipes need to be buried in the ground surface, which is a time-consuming and laborious project. Moreover, when burying the buried pipes, the construction is mostly carried out in open and unobstructed areas. Under direct sunlight during the day, the temperature is very high, and the construction environment for workers is very poor. In order to ensure the construction progress on time, there is a great risk of heat stroke for construction workers when they work continuously.

[0003] In order to improve the construction environment, conventional cooling devices such as fans and air conditioners are used. However, in an open construction environment, the cooling effects of this type of cooling device are not ideal: the fan cannot reduce the surrounding environment temperature, while the air conditioner has the problem of high power consumption. Utility Model Content

[0004] In order to improve the construction environment at the construction site, this application provides a cooling device using a ground source heat pump buried pipe.

[0005] The cooling device using a ground source heat pump buried pipe provided by this application adopts the following technical solutions:

[0008] The blowing mechanism is used to make air flow through the heat exchange mechanism to reduce the air flow temperature.

[0009] By adopting the above technical solutions, the blowing mechanism guides the external high-temperature air flow into the heat exchange mechanism, and performs heat exchange with the low-temperature heat exchange medium through the first heat exchanger, thereby reducing the air flow temperature. Then, the cooled air flow is discharged through the blowing mechanism to provide a cool environment for the construction site.

[0010] Preferably, the first heat exchanger includes a cooling water curtain and a spraying assembly, and the spraying assembly is communicated with the inlet pipe and is used to spray the heat exchange medium onto the cooling water curtain.

[0011] By adopting the above technical solutions, the low-temperature heat exchange medium is evenly sprayed on the cooling water curtain through the spraying assembly, increasing the contact area between the heat exchange medium and the air flow, improving the heat exchange efficiency, and thus enhancing the cooling effect.

[0012] Preferably, the first heat exchanger further includes a water replenishing component for replenishing the heat exchange medium into the ground buried pipe.

[0013] By adopting the above technical solution, the water replenishing component can replenish the ground buried pipe in time when the water volume is insufficient, ensuring the continuous progress of the heat exchange process and improving the stability and durability of the device.

[0014] Preferably, the first heat exchanger further includes a liquid collector connected to the water inlet pipe, and the spraying component is connected to the liquid collector.

[0015] By adopting the above technical solution, the storage of the heat exchange medium is realized through the liquid collector, which can ensure the sufficient supply of the heat exchange medium, thus ensuring the continuous and stable operation of the first heat exchanger.

[0016] Preferably, the liquid collector is arranged below the cooling water curtain, and a collection port is arranged at the top of the liquid collector; the drain pipe is connected to the liquid collector.

[0017] By adopting the above technical solution, the liquid collector is used to collect the heat exchange medium flowing down from the cooling water curtain, realizing the recycling of the heat exchange medium, reducing resource waste and simultaneously reducing the operation cost.

[0018] Preferably, multiple groups of the first heat exchangers are provided and arranged in parallel.

[0019] By adopting the above technical solution, by increasing the number of the first heat exchangers, the heat exchange area is expanded, further improving the cooling capacity and efficiency of the cooling device and adapting to the construction sites of different scales and requirements.

[0021] The second heat exchange component includes a cooling water curtain and a spraying component, and the spraying component is connected with a component for connecting to the tap water source.

[0022] By adopting the above technical solution, the setting of the second heat exchanger can use tap water for preliminary cooling, reducing the burden on the first heat exchanger, improving the overall cooling effect, and at the same time, tap water as a supplementary water source enhances the adaptability and flexibility of the device.

[0023] Preferably, it further includes a casing, and an air inlet and an air outlet are provided on the casing, and the air blowing mechanism and the cooling mechanism are both arranged inside the casing.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1.

Detailed Description of the Embodiment

[0031] The following is a further detailed description of the present application in conjunction with the attached Figure 1 drawings.

[0032] This embodiment discloses a cooling device using a ground source heat pump buried pipe, including an air blowing mechanism 1 and a heat exchange mechanism 2. The heat exchange mechanism 2 includes a first heat exchanger 21 and a first water pump 22. An inlet pipe and a drain pipe for connecting to the buried pipe 4 are provided on the first heat exchanger 21, and the first water pump 22 is connected to the inlet pipe for introducing the heat exchange medium in the buried pipe 4 into the first heat exchanger 21. The air blowing mechanism 1 is used to make the air flow pass through the heat exchange mechanism 2, thereby reducing the air flow temperature.

[0033] The first heat exchanger 21 further includes a cooling water curtain 211 and a spraying assembly 212. The spraying assembly 212 is communicated with the water inlet pipe and is used to spray the heat exchange medium onto the cooling water curtain 211. The heat exchange medium sprayed on the cooling water curtain 211 exchanges heat with the passing air flow, thereby reducing the temperature of the air flow.

[0034] The cooling filler inside the cooling water curtain 211 can be made of honeycomb paper, or straw, fiberglass, ceramic materials, etc., to reduce costs.

[0035] To realize the recycling of the heat exchange medium, the first heat exchanger 21 further includes a liquid collector 213. The liquid collector 213 is arranged below the cooling water curtain 211 and collects the heat exchange medium dripping from the cooling water curtain 211 through the collection port at its top. The liquid collector 213 is connected to the water inlet pipe, and the spraying assembly 212 is connected to the liquid collector 213, thus forming a circulation loop. The drain pipe is connected to the liquid collector 213 and is used to discharge the excess heat exchange medium.

[0036] The air blowing mechanism 1 and the heat exchange mechanism 2 are both arranged in a machine shell 3. An air inlet and an air outlet are provided on the machine shell 3. During operation, the air blowing mechanism 1 sucks in the air flow from the air inlet, makes the air flow pass through the heat exchange mechanism 2 for cooling, and then discharges the cooled air flow from the air outlet.

[0037] Using the low-temperature heat exchange medium in the ground source heat pump system, it is sprayed onto the cooling water curtain 211 through the spraying assembly 212. When the air flow sucked in by the air blowing mechanism 1 passes through the cooling water curtain 211, it exchanges heat with the low-temperature heat exchange medium, thereby reducing the temperature of the air flow. The cooled air flow is then discharged through the air outlet to provide a cooling effect for the construction site.

[0038] Furthermore, the first heat exchanger 21 further includes a water replenishing assembly. The water replenishing assembly can be connected to components such as the liquid collector 213 and the drain pipe, and is used to replenish the heat exchange medium into the ground heat exchanger 4. During long-term operation, since the cooling water curtain 211 uses evaporative cooling, the heat exchange medium in the ground heat exchanger 4 may gradually decrease. The water replenishing assembly can timely replenish the heat exchange medium into the ground heat exchanger 4 to ensure the continuous and stable operation of the cooling device.

[0039] In the embodiment of the present application, multiple groups of the first heat exchangers 21 can be provided and are distributed in parallel. Multiple groups of the first heat exchangers 21 can work simultaneously, increasing the heat exchange area, thereby improving the cooling effect and working efficiency of the cooling device.

[0040] Furthermore, the heat exchange mechanism 2 further includes a second heat exchanger 23. The second heat exchanger 23 is arranged in parallel with the first heat exchanger 21, and the air flow passes through the second heat exchanger 23 and the first heat exchanger 21 in sequence. The second heat exchanger 23 is also composed of a cooling water curtain 211, a spraying assembly 212, and a liquid collector 213. And in the second heat exchanger 23, a pipeline for connecting to a tap water source is connected to the spraying assembly 212. By introducing tap water as the heat exchange medium of the second heat exchanger 23, the cooling effect of the cooling device is further enhanced. Moreover, since the tap water has its own water pressure, the use of a water pump is eliminated and automatic water supply is achieved. At the same time, the second heat exchanger 23 and the first heat exchanger 21 can work independently or simultaneously to adapt to different environmental temperatures and construction requirements.

[0041] In addition to adopting the structure form of the cooling water curtain 211, the first heat exchanger 21 and the second heat exchanger 23 in the embodiments of the present application can also adopt structures such as heat exchange coils and heat exchange grids, with diverse structure forms.

[0042] In addition, the air blowing mechanism 1 adopts a high-efficiency and low-noise fan to improve the air flow circulation efficiency and reduce noise pollution. In addition, the air blowing mechanism 1 is also equipped with a wind speed adjustment device, which can flexibly adjust the wind speed at the air outlet according to the actual needs of the construction site, so as to achieve a more precise cooling effect.

[0043] In summary, the first heat exchanger 21 is connected to the buried pipe drilling make-up tap water. After the ambient hot air passes through the first heat exchanger 21 and exchanges heat with the tap water make-up, the temperature is reduced. At this time, the outlet air temperature is below the wet bulb temperature. The second heat exchanger 23 is connected to the buried pipe heat exchanger. By utilizing the environment with a constant temperature of about 18 °C underground, the water temperature can reach about 23 °C. At this time, the temperature of the wind can be further reduced, and the cooling effect is better when blowing on the workers.

[0044] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
