Description

Technical Field

[0001] This invention relates to the field of heating, ventilation and heat dissipation technology, and in particular to a high-efficiency heat dissipation structure for heating, ventilation and air conditioning systems. Background Technology

[0002] According to the load medium, HVAC systems can be classified into all-air systems, all-water systems, and direct evaporation unit systems. The characteristics of an all-water system are: the room load is borne by a centralized supply of chilled and hot water. The chilled water produced by the central unit is circulated to the coils in the air handling unit to regulate the indoor air. Heating is achieved by the circulation of hot water in the coils. When the environment only requires cooling or heating, or heating and cooling cannot be carried out simultaneously, a two-pipe system can be used. In this system, the hot water required for heating is produced by an electric heater or boiler and then dissipated using a heat dissipation structure.

[0003] Currently, existing heat dissipation structures still have certain shortcomings. During use, the heat dissipation efficiency is low, and it is impossible to dissipate the heat energy in the hot water in a timely manner. At the same time, the heat energy dissipated changes only with the temperature of the hot water itself and cannot be regulated by the heat dissipation mechanism itself. Therefore, it is urgent to design a high-efficiency heat dissipation structure for HVAC to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to address the deficiencies in the existing technology by proposing a high-efficiency heat dissipation structure for HVAC systems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-efficiency heat dissipation structure for HVAC includes a heat dissipation box containing a coil. A hot water inlet pipe is fixedly installed through one outer wall of the heat dissipation box, with one end of the hot water inlet pipe connected to one end of the coil. A wastewater outlet pipe is fixedly installed through the other outer wall of the heat dissipation box, with one end of the wastewater outlet pipe connected to the other end of the coil. Fixed covers are provided on both the bottom and top outer walls of the heat dissipation box, and heat dissipation plates are installed within the fixed covers. An air pump is installed on the outer wall of the fixed covers, and an air guide pipe is installed at the air pump's air guide end, with the end of the air guide pipe communicating with the fixed cover. The fixed cover and the heat dissipation box are connected via a connecting pipe. An air outlet pipe is fixedly installed through one outer wall of the heat dissipation box. The structure also includes:

[0007] A heat conduction mechanism is disposed in the gap of the coil and is used to conduct heat in the coil to the heat sink.

[0008] An adjustment mechanism is provided on the outside of the connecting pipe to directly guide the gas discharged from the connecting pipe to the outlet pipe.

[0009] As a further embodiment of the present invention: the adjusting mechanism includes:

[0010] A sealing assembly, disposed on the inner wall of the heat sink, is used to seal the end of the connecting pipe;

[0011] A flow guiding component is disposed on the outer wall of the connecting pipe and is used to direct the gas in the connecting pipe into the outlet pipe when the sealing component seals the connecting pipe.

[0012] As a further embodiment of the present invention: the sealing component includes a telescopic member that is fixedly disposed through the inner wall of one side of the heat sink, and the telescopic end of the telescopic member is provided with a cover plate, the inner wall of the cover plate is provided with a sealing gasket, and the sealing gasket is located at the port of the connecting pipe.

[0013] As a further embodiment of the present invention: the flow guiding assembly includes an installation cylinder, one end of which is fixedly provided with a fixing pipe, and the end of the fixing pipe is connected to a connecting pipe. Adjacent installation cylinders are connected by a connecting pipe, and the outer wall of the connecting pipe is provided with a flow guiding pipe. The end of the flow guiding pipe is connected to an air outlet pipe. A piston is also movably provided in the installation cylinder, and the outer wall of the piston is provided with a movable rod. The movable rod passes through the installation cylinder, and the outer wall of the movable rod is sleeved with an elastic element. One end of the elastic element is connected to the outer wall of the piston, and the other end of the elastic element is connected to the inner wall of the installation cylinder.

[0014] As a further embodiment of the present invention: the heat conduction mechanism includes a heat conduction rod that penetrates the heat dissipation box and is disposed in the gap of the coil. The end of the heat conduction rod is connected to the outer wall of the heat dissipation plate. Heat absorption fins are provided on both sides of the outer wall of the heat conduction rod at equal intervals. The outer wall of the coil is provided with mounting holes at equal intervals, and the ends of the heat absorption fins are fixedly disposed in the mounting holes.

[0015] As a further embodiment of the present invention: both the air pump and the telescopic component are connected to a switch via wires, and the switch is electrically connected to a controller.

[0016] As a further embodiment of the present invention: the outer wall of the heat sink is provided with equidistant ventilation holes, and the outer walls on both sides of the heat sink are also provided with staggered baffles.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] This invention provides a high-efficiency heat dissipation structure for HVAC systems. Hot water from the boiler is introduced into the coil through a hot water inlet pipe and then discharged through a wastewater outlet pipe. When the hot water is introduced into the coil, the heat is absorbed by the heat conduction mechanism and then transferred to the heat dissipation plate. At this time, an air pump draws in outside air through an exhaust pipe and then guides it into a fixed cover through the exhaust pipe. The heat dissipation plate in the fixed cover heats the air inside, allowing the heated air to be introduced into the heat dissipation box through a connecting pipe. Heat continues to radiate from around the coil, further heating the air and allowing the heat to dissipate into the coil. The heat energy of the hot water can be quickly converted into the air and then discharged through the air outlet pipe. When the outside temperature reaches a suitable value, there is no need to supply higher-temperature air to the outside. At this time, the air introduced through the connecting pipe can be directly guided to the air outlet pipe and discharged through the adjustment mechanism, eliminating the step of introducing the air into the heat dissipation box for further heating. With the initial temperature of the introduced hot water remaining unchanged, the temperature of the discharged air can be freely adjusted, making it more flexible to use. The above structure effectively realizes the rapid transfer of heat energy in the hot water into the air. At the same time, while ensuring that the temperature of the introduced hot water remains unchanged, the temperature of the discharged air can be adjusted in two levels, resulting in better performance.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] like Figure 1 As shown, an embodiment of the present invention provides a high-efficiency heat dissipation structure for HVAC, including a heat dissipation box 1, a coil 2 disposed in the heat dissipation box 1, a hot water inlet pipe 3 fixedly disposed through one side outer wall of the heat dissipation box 1, one end of the hot water inlet pipe 3 being connected to one end of the coil 2, a wastewater discharge pipe 16 fixedly disposed through the other side outer wall of the heat dissipation box 1, one end of the wastewater discharge pipe 16 being connected to the other end of the coil 2, a fixing cover 5 disposed on both the bottom and top outer walls of the heat dissipation box 1, a heat dissipation plate 9 disposed in the fixing cover 5, an air pump 7 disposed on the outer wall of the fixing cover 5, and an air guide pipe 6 disposed at the air guide end of the air pump 7, the end of the air guide pipe 6 being connected to the fixing cover 5, the fixing cover 5 and the heat dissipation box 1 being connected by a connecting pipe 18, an air outlet pipe 4 fixedly disposed through one side outer wall of the heat dissipation box 1, and further comprising:

[0026] The heat conduction mechanism 20 is disposed in the gap of the coil 2 and is used to conduct the heat in the coil 2 to the heat sink 9.

[0027] Adjustment mechanism 12 is located on the outside of connecting pipe 18 and is used to directly guide the gas discharged from connecting pipe 18 to gas outlet pipe 4.

[0028] Hot water from the boiler can be introduced into coil 2 through hot water inlet pipe 3, and then discharged through wastewater outlet pipe 16. When hot water is introduced into coil 2, the heat conduction mechanism 20 absorbs the heat from the hot water in coil 2, and then conducts the heat to radiator plate 9. At this time, outside air can be drawn in through air extraction pipe 8 by air pump 7, and then introduced into fixed cover 5 through air guide pipe 6. The radiator plate 9 in fixed cover 5 can heat the air inside fixed cover 5, so that the heated air can be introduced into radiator box 1 through connecting pipe 18. At this time, heat can still be emitted around coil 2, further heating the air, so that the hot water in coil 2 can be heated. Heat energy can be quickly converted into air and then discharged through the air outlet pipe 4. When the outside temperature reaches a suitable value and there is no need to supply higher temperature air to the outside, the air introduced through the connecting pipe 18 can be directly guided to the air outlet pipe 4 and discharged through the adjustment mechanism 12, eliminating the step of introducing the air into the heat dissipation box 1 for further heating. With the initial temperature of the introduced hot water remaining unchanged, the temperature of the discharged air can be freely adjusted, making it more flexible to use. The above structure effectively realizes the rapid transfer of heat energy in the hot water to the air. At the same time, while ensuring that the temperature of the introduced hot water remains unchanged, the temperature of the discharged air can be adjusted in two levels, resulting in better performance.

[0029] As one embodiment of the present invention, please refer to Figure 1 , Figure 2 and Figure 3 The regulating mechanism 12 includes:

[0030] A sealing component 19 is disposed on the inner wall of the heat sink 1 and is used to seal the end of the connecting pipe 18.

[0031] The flow guiding component 14 is disposed on the outer wall of the connecting pipe 18 and is used to direct the gas in the connecting pipe 18 into the gas outlet pipe 4 when the sealing component 19 seals the connecting pipe 18.

[0032] As one embodiment of the present invention, please refer to Figure 1 and Figure 2 The sealing assembly 19 includes a telescopic member 23 that is fixedly installed through the inner wall of one side of the heat sink 1. The specific structure of the telescopic member 23 is not limited. In this embodiment, preferably, the telescopic member 23 is an electric telescopic rod, and the telescopic end of the telescopic member 23 is provided with a cover plate 24. The inner wall of the cover plate 24 is provided with a sealing gasket 25, and the sealing gasket 25 is located at the port of the connecting pipe 18. When it is necessary to close the end of the connecting pipe 18, the cover plate 24 can be moved by the telescopic member 23, and the end of the connecting pipe 18 can be sealed by the sealing gasket 25 on the cover plate 24, which is very convenient to use.

[0033] As one embodiment of the present invention, please refer to Figure 1 and Figure 3The flow guiding assembly 14 includes an installation cylinder 26, one end of which is fixedly connected to a fixing pipe 17, and the end of the fixing pipe 17 is connected to a connecting pipe 18. Adjacent installation cylinders 26 are connected by a connecting pipe 15, and the outer wall of the connecting pipe 15 is provided with a flow guiding pipe 13, the end of which is connected to an outlet pipe 4. A piston 29 is also movably installed in the installation cylinder 26, and the outer wall of the piston 29 is provided with a movable rod 27, which penetrates the installation cylinder 26. An elastic element 28 is sleeved on the outer wall of the movable rod 27. The specific structure of the elastic element 28 is not limited. In this embodiment, preferably, the elastic element 28 is a spring, one end of which is connected to the outer wall of the piston 29, and the elastic element 28... The other end is connected to the inner wall of the mounting cylinder 26. When one end of the connecting pipe 18 is blocked by the sealing component 19, air is still continuously input into the connecting pipe 18. At this time, the air pressure in the connecting pipe 18 increases, and the air can enter the mounting cylinder 26 through the fixed pipe 17, causing the piston 29 to move in the mounting cylinder 26, so that the elastic element 28 on the outside of the movable rod 27 is compressed until the end of the connecting pipe 15 is exposed. At this time, the air can enter the connecting pipe 15, and then be directly introduced into the exhaust pipe 4 and discharged along the guide pipe 13 on the outer wall of the connecting pipe 15. This reduces the step of further heating the air through the coil 2 in the heat dissipation box 1, so that the temperature of the discharged air is lower than the temperature of the previously discharged air, resulting in better performance.

[0034] As one embodiment of the present invention, please refer to Figure 1 and Figure 4 The heat conduction mechanism 20 includes a heat conduction rod 21 that penetrates the heat dissipation box 1 and is disposed in the gap of the coil 2. The end of the heat conduction rod 21 is connected to the outer wall of the heat dissipation plate 9. Heat absorption fins 22 are provided on both sides of the outer wall of the heat conduction rod 21 at equal intervals. The outer wall of the coil 2 is provided with mounting holes at equal intervals, and the ends of the heat absorption fins 22 are fixedly disposed in the mounting holes. Hot water in the coil 2 can be directly absorbed by the heat absorption fins 22 and then conducted to the heat conduction rod 21 through the heat absorption fins 22. Then, it can be conducted to the heat dissipation plate 9 through the heat conduction rod 21, which is very convenient to use.

[0035] In one embodiment of the present invention, both the air pump 7 and the telescopic component 23 are connected to a switch via wires, and the switch is electrically connected to a controller. The specific structure of the controller is not limited. In this embodiment, preferably, the controller is a microprogrammed controller.

[0036] As one embodiment of the present invention, please refer to Figure 1 and Figure 4The outer wall of the heat sink 9 is provided with equidistant vent holes 11, and the outer walls on both sides of the heat sink 9 are also provided with staggered baffles 10. The air introduced into the fixing cover 5 can pass through the vent holes 11 on the heat sink 9. Under the blocking effect of the staggered baffles 10, the air can continuously pass through the vent holes 11 and shuttle back and forth on the upper and lower sides of the heat sink 9, which can fully conduct the heat of the heat sink 9 into the air, and the use effect is better.

[0037] In operation, hot water from the boiler is introduced into coil 2 through hot water inlet pipe 3, and then discharged through wastewater outlet pipe 16. When hot water is introduced into coil 2, the heat conduction mechanism 20 absorbs the heat from the hot water in coil 2, and then conducts the heat to radiator plate 9. At this time, outside air is drawn in through air extraction pipe 8 by air pump 7, and then introduced into fixed cover 5 through air guide pipe 6. The radiator plate 9 in fixed cover 5 heats the air inside fixed cover 5, allowing the heated air to be introduced into radiator box 1 through connecting pipe 18. At this time, heat can still be emitted around coil 2, further heating the air and making the heat in coil 2 more concentrated. The heat energy of the water can be quickly converted into the air and then discharged through the air outlet pipe 4. When the outside temperature reaches a suitable value and there is no need to supply higher temperature air to the outside, the air introduced through the connecting pipe 18 can be directly guided to the air outlet pipe 4 and discharged through the regulating mechanism 12, eliminating the step of introducing the air into the heat dissipation box 1 for further heating. With the initial temperature of the introduced hot water remaining unchanged, the temperature of the discharged air can be freely adjusted, making it more flexible to use. The above structure effectively realizes the rapid transfer of heat energy in the hot water to the air. At the same time, while ensuring that the temperature of the introduced hot water remains unchanged, the temperature of the discharged air can be adjusted in two levels, resulting in better performance.

[0038] It should be noted that although this specification describes the embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
