Description

Technical Field

[0001] This utility model relates to the field of composite pipes and their application technology, and in particular to a water-air composite pipe and a natural temperature-regulating ventilation device. Background Technology

[0002] Traditional ventilation systems mostly only allow air circulation and cannot effectively regulate air temperature. Common air conditioning devices, such as air conditioners, typically consume large amounts of electricity to achieve temperature control, increasing energy consumption and potentially causing adverse environmental impacts. Furthermore, the temperature control process is relatively enclosed, resulting in poor air circulation. Additionally, some devices that combine ventilation and temperature control functions are complex in structure, expensive, and have limitations in terms of temperature control effectiveness and energy efficiency, making it difficult to achieve natural, efficient, and economical air temperature control and recycling. Utility Model Content

[0003] This utility model aims to provide a water-air composite pipe and a natural temperature-regulating ventilation device. The connection structure of the specific ventilation channel of the water-air composite pipe can simultaneously realize water flow and ventilation functions. When water flows through the inner water pipe, the air in the ventilation channel can also utilize the temperature conducted by the water in the inner water pipe to achieve natural temperature regulation. The natural temperature-regulating ventilation device is based on the water-air composite pipe and, by combining a water storage device and a spray design, can both regulate the temperature of the incoming air and achieve water recycling. In addition, the ventilation channel structure design of the water-air composite pipe further regulates the temperature of the air entering the ventilation channel, improving the temperature regulation effect.

[0004] This utility model's natural temperature regulation ventilation device does not require complex and costly equipment; it can achieve the effect of natural temperature regulation by utilizing existing fire-fighting sealed water tanks or sealed water wells.

[0005] To solve the above problems, this utility model achieves this through the following technical solution:

[0006] The first objective of this invention is:

[0007] A water-air composite pipe is provided, comprising: an outer ventilation pipe and an inner water pipe installed inside the outer ventilation pipe, wherein a ventilation channel exists between the inner wall of the outer ventilation pipe and the outer wall of the inner water pipe.

[0008] The water-passing inner pipe is made of a metal material with good thermal conductivity;

[0009] The ventilation channel is closed at one end A of the outer ventilation pipe, but the end of the inner water pipe corresponding to the closed end A of the outer ventilation pipe continues to extend beyond the closed end A of the outer ventilation pipe, becoming the outlet of the inner water pipe; the other end of the inner water pipe is the inlet of the inner water pipe.

[0010] The other end B of the ventilation duct is the air inlet a;

[0011] The ventilation duct has at least one air outlet a on its wall, which is connected to the ventilation channel.

[0012] Outside air enters through the air inlet a at the end B of the ventilation duct and exits through the air outlet a on the duct wall.

[0013] External water enters from the inlet near the end B of the ventilation duct and exits from the outlet at the closed end A of the ventilation duct. Water circulation can also be achieved as needed.

[0014] The water-air composite pipe of this utility model is further optimized as follows:

[0015] The inner water pipe is composed of multiple small water pipes clustered together, with all gaps between them sealed, or it is a multi-hole water pipe. The design of multiple small water pipes or a multi-hole structure can make the water flow more stable and the temperature regulation effect more stable; on the other hand, the fact that it is composed of multiple small water pipes clustered together can increase the contact area between the outer surface of the inner water pipe and the air, which can enhance the temperature regulation effect.

[0016] The water-air composite pipe of this utility model is further optimized as follows:

[0017] The water-conducting inner pipe section outside the closed end A of the ventilation outer pipe has only one water-conducting inner channel;

[0018] The water-passing inner pipe enters the ventilation outer pipe through an installation hole on the pipe wall near the end B of the ventilation outer pipe. After installation, the installation hole and the outer wall of the water-passing inner pipe are sealed.

[0019] The water-air composite pipe of this utility model is further optimized as follows:

[0020] A support bracket is installed on the outer wall of the inner water pipe. This bracket is located within the ventilation channel between the outer wall of the inner water pipe and the inner wall of the outer ventilation pipe, supporting the two pipes. The support bracket must not block the ventilation channel and must ensure unobstructed ventilation. The use of the support bracket ensures the consistency and smoothness of the ventilation channel.

[0021] The water-air composite pipe of this utility model is further optimized as follows:

[0022] The ventilation duct is made of segments, and its length can be flexibly adjusted according to actual needs. It can also be convenient to fix and install when the support bracket needs to be welded or fixed. In addition, it can also facilitate special installation operations such as bending.

[0023] The water-air composite pipe of this utility model is further optimized as follows:

[0024] The water-passing inner pipe is made of segmented connection, and its length can be flexibly adjusted according to actual needs.

[0025] This utility model's water-air composite pipe uses a large pipe enclosing a small pipe (preferably with a support frame). Water flows through the inner water pipe (small pipe), and ventilation is provided through the ventilation channel formed between the outer ventilation pipe (large pipe) and the inner water pipe (small pipe). One end of the outer ventilation pipe is sealed, and multiple air outlets 'a' are provided on the wall of the outer ventilation pipe, which are connected to the ventilation channel. This allows for the convenient introduction of air at a suitable temperature into the corresponding space, depending on the actual situation.

[0026] The second objective of this invention is:

[0027] A natural temperature-regulating ventilation device is provided, comprising: a water storage device and the aforementioned water-air composite pipe;

[0028] The water storage device is a sealed container, and the top plane of the water storage device is provided with: air inlet b, air outlet b, circulating water inlet, circulating water outlet and tap water inlet;

[0029] The air inlet b is connected to the outside air; preferably, there is a perforated isolation structure at the air inlet b to prevent foreign objects, fallen leaves, etc.

[0030] The water storage device is equipped with a water pump and multiple spray heads. The water inlet of the water pump is located below the water surface of the water storage device, and the spray heads are located above the water surface of the water storage device. The water outlet of the water pump is connected to the spray heads. The spray heads are designed to regulate the temperature of the outside air entering the water storage device when spraying water (utilizing the property of water being warm in winter and cool in summer to achieve the effect of cooling in summer and warming in winter). In addition, spraying water can also reduce particulate matter such as dust in the air, making the air fresher.

[0031] The air inlet a at the end B of the water-air composite pipe is connected to the air outlet b on the water storage device.

[0032] The air outlet a on the wall of the water-air composite pipe is connected to the exhaust fan and guided to the space to be reached (preferably, a detachable dustproof net can also be installed between the air outlet a and the exhaust fan for easy cleaning in the future); when the exhaust fan is ventilating, it will discharge the air at a suitable temperature above the water surface in the ventilation channel and the water storage device to the target space.

[0033] The water inlet near the end B of the ventilation pipe is connected to the circulating water outlet on the water storage device; the circulating water outlet is connected to the water pump, and the water inlet of the water pump is located below the water surface of the water storage device.

[0034] The outlet of the closed end A of the ventilation pipe is connected to the circulating water inlet on the water storage device.

[0035] The natural temperature regulating ventilation device of this utility model is further optimized as follows:

[0036] The multiple spray heads are arranged at corresponding intervals along the inner wall of the water storage device. The arrangement of the spray heads can regulate the temperature of the air entering the water storage device, mainly utilizing the property of water being warm in winter and cool in summer compared to air.

[0037] The natural temperature regulating ventilation device of this utility model is further optimized as follows:

[0038] The water storage device is equipped with a water level limit to ensure that the device can operate normally for a long time.

[0039] The natural temperature regulating ventilation device of this utility model is further optimized as follows:

[0041] The natural temperature regulating ventilation device of this utility model can make full use of the water in the water storage device to cool the incoming air (through the spraying action of the spray head), and at the same time, it can also conduct the temperature of the water in the pipe to the air in the ventilation channel through the water pipe, thereby achieving the effect of regulating the temperature of the air in the ventilation channel.
