Description

Technical Field

[0001] This invention relates to the field of heat exchange equipment technology, and more specifically to an air conditioning coil circulation pipeline that facilitates heat exchange. Background Technology

[0002] Fan coil units consist of fans, coils, and filters. As terminal devices of the air conditioning system, they are installed in various air-conditioned rooms and can independently process the air. The hot and cold water required for air processing is centrally prepared in the air conditioning room and supplied to each fan coil unit through the water supply system.

[0003] However, most air conditioning coils on the market are single-pass coils. Single-pass coils only have one channel for refrigerant or heat transfer, resulting in a relatively small contact area with the pipe wall and thus relatively low heat exchange efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide an air conditioning coil circulation pipeline that facilitates heat exchange, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: An air conditioning coil circulation pipeline for easy heat exchange includes an equipment housing, a heat exchange chamber, and an air supply chamber. A combined coil is fixedly connected to the inner wall of the heat exchange chamber, and a fan is fixedly connected to the inner wall of the air supply chamber.

[0006] The combined coil includes a water inlet pipe, a penetrating heat exchange tube fixedly connected to the top end of the water inlet pipe, a spiral heat exchange tube fixedly connected to the outer wall of the water inlet pipe, a drain pipe fixedly connected to the outlet end of the penetrating heat exchange tube, the outer wall of the drain pipe fixedly connected to the outlet end of the spiral heat exchange tube, fins fixedly connected to the outer wall of the water inlet pipe, and the penetrating heat exchange tube located in the vertical space of the spiral heat exchange tube, and the two do not contact each other.

[0007] The inner wall of the air supply chamber is provided with a vibration damping and noise reduction component for damping and reducing the noise of the fan.

[0008] A further improvement of the technical solution of the present invention is that: the vibration damping and noise reduction assembly includes a sound-absorbing cotton layer located on the inner wall of the air supply chamber, and vibration damping components disposed on both sides of the fan. The vibration damping component includes a fixing ring fixedly connected to the inner wall of the air supply chamber, a spring damping rod fixedly connected to the inner wall of the fixing ring, an installation collar fixedly connected to one end of the spring damping rod, a fixing rod fixedly connected to the inner wall of the installation collar, and one end of the fixing rod fixedly connected to one side of the fan.

[0009] A further improvement of the technical solution of the present invention is that: the number of spring damping rods is eight sets, and the eight sets of spring damping rods are distributed in a ring array on the outer wall of the mounting collar.

[0010] A further improvement of the technical solution of the present invention is that a wind guide plate is fixedly connected to the top of the inner wall of the equipment housing.

[0011] A further improvement of the technical solution of the present invention is that a water receiving tray is provided below the combined coil, and the bottom surface of the water receiving tray is fixedly connected to the bottom of the inner wall of the heat exchange chamber.

[0012] A further improvement of the technical solution of the present invention is that the bottom ends of both the water inlet pipe and the water outlet pipe extend to the bottom of the equipment housing.

[0013] A further improvement of the technical solution of the present invention is that: the inner wall of the water inlet pipe is fixedly connected with auxiliary micro ribs.

[0014] Due to the adoption of the above technical solution, the technical progress achieved by this invention compared to the prior art is as follows: 1. This invention provides an air conditioning coil circulation pipe that facilitates heat exchange. By using an inlet pipe, a spiral heat exchanger pipe, and a through-type heat exchanger pipe in combination, the fluid continuously changes direction as it flows inside the pipe, promoting fluid turbulence, reducing the influence of the boundary layer, and enhancing the heat exchange effect. At the same time, by utilizing the flow diversion effect formed by the through-type heat exchanger pipe and the spiral heat exchanger pipe, the space ratio of the combined coil is reduced while further increasing its surface area in contact with air, thereby further enhancing the heat exchange effect.

[0015] 2. This invention provides an air conditioning coil circulation pipeline that facilitates heat exchange. By using a combination of a fixing ring, a spring damping rod, a mounting collar, and a fixing rod, the vibration generated during the operation of the fan can be buffered. Combined with the sound absorption effect of the sound-absorbing cotton layer, the noise generated by the fan can be reduced, and the comfort of using the device can be improved.

[0018] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0019] The present invention will be further described in detail below with reference to embodiments: Example 1 like Figure 1-4 As shown, the present invention provides an air conditioning coil circulation pipeline that facilitates heat exchange, including a housing 1, a heat exchange chamber 4 and an air supply chamber 5. A combined coil 2 is fixedly connected to the inner wall of the heat exchange chamber 4, and a fan 3 is fixedly connected to the inner wall of the air supply chamber 5.

[0020] The combined coil 2 includes an inlet pipe 8, with a through-type heat exchange tube 10 fixedly connected to the top end of the inlet pipe 8. A spiral heat exchange tube 9 is fixedly connected to the outer wall of the inlet pipe 8. A drain pipe 11 is fixedly connected to the outlet end of the through-type heat exchange tube 10. The outer wall of the drain pipe 11 is fixedly connected to the outlet end of the spiral heat exchange tube 9. Fins 16 are fixedly connected to the outer wall of the inlet pipe 8. The through-type heat exchange tube 10 is located in the vertical space of the spiral heat exchange tube 9, and the two do not contact each other.

[0021] The inner wall of the air supply chamber 5 is equipped with a vibration damping and noise reduction component for damping and reducing the noise of the fan 3.

[0022] The vibration damping and noise reduction assembly includes a sound-absorbing cotton layer 6 located on the inner wall of the air supply chamber 5, and vibration damping components disposed on both sides of the fan 3. The vibration damping components include a fixing ring 14 fixedly connected to the inner wall of the air supply chamber 5, a spring damping rod 15 fixedly connected to the inner wall of the fixing ring 14, an installation collar 13 fixedly connected to one end of the spring damping rod 15, a fixing rod 12 fixedly connected to the inner wall of the installation collar 13, and one end of the fixing rod 12 fixedly connected to one side of the fan 3.

[0023] The inner wall of the water inlet pipe 8 is fixedly connected with auxiliary micro-ribs. The auxiliary micro-rib structure in the water inlet pipe 8 can increase the turbulence of the fluid. Under turbulent conditions, strong mixing will occur between different parts of the fluid, and the cold fluid and the hot fluid can come into more complete contact, thereby greatly improving the efficiency of heat transfer.

[0024] Example 2 like Figure 1-4 As shown, based on Embodiment 1, the present invention provides a technical solution: preferably, the number of spring damping rods 15 is eight sets, and the eight sets of spring damping rods 15 are distributed in a ring array on the outer wall of the mounting collar 13.

[0025] A wind guide plate 17 is fixedly connected to the top of the inner wall of the equipment housing 1.

[0026] A water receiving tray 7 is provided below the combined coil 2, and the bottom surface of the water receiving tray 7 is fixedly connected to the bottom of the inner wall of the heat exchange chamber 4.

[0027] The bottom ends of both the water inlet pipe 8 and the drain pipe 11 extend to the bottom of the equipment housing 1.

[0028] The working principle of this heat exchange-facilitating air conditioning coil circulation system will be explained in detail below.

[0029] like Figure 1-4 As shown, during use, the refrigerant is delivered to the inlet pipe 8. When the refrigerant is delivered to the spiral heat exchanger tube 9 through the inlet pipe 8, the spiral structure of the spiral heat exchanger tube 9 causes the fluid to continuously change direction as it flows inside the tube, promoting fluid turbulence, reducing the influence of the boundary layer, and enhancing the heat exchange effect. At the same time, a portion of the refrigerant delivered in the inlet pipe 8 is also diverted to the penetrating heat exchanger tube 10. The penetrating heat exchanger tube 10 penetrates the vertical space of the spiral heat exchanger tube 9, reducing the space ratio of the combined coil 2 while further increasing its surface area in contact with air, thereby further enhancing the heat exchange effect.

[0030] The fins 16 on the outer wall of the inlet pipe 8 can further enhance the contact area between the pipe wall and the air, thus further enhancing the heat exchange effect. The structure of the through-type heat exchange tube 10 and the spiral heat exchange tube 9 is the same as that of the inlet pipe 8.

[0031] When the fan 3 is running and blowing air into the heat exchange chamber 4, the resistance of the inner wall of the heat exchange chamber 4 to the air blowing process is reduced under the guidance of the air guide plate 17, so that the air force can be output through the air outlet more smoothly.

[0032] Meanwhile, during the vibration generated by the operation of the fan 3, the fixing rod 12 on its side will drive the mounting ring 13 to start vibrating. The mounting ring 13 will then squeeze or pull the spring damping rod 15. Moreover, the spring damping rod 15 is distributed in multiple directions, which can more comprehensively absorb the vibration generated by the fan 3 to reduce the noise it generates. At the same time, after the sound-absorbing cotton layer 6 absorbs the noise, the noise reduction effect of the device is further improved.

[0033] It should be noted that, in this document, the terms "comprising," "including," or any other variations are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element. The present invention has been described in detail above, but modifications or improvements can be made based on it, which will be apparent to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
