Description

Technical Field

[0001] The invention relates to the field of HVAC equipment, and in particular to a high-efficiency heat exchange component for HVAC equipment. Background Art

All equipment related to heating and ventilation, such as air conditioners, ventilation ducts, control equipment, water heating boilers, pipes, radiators, and electric heating equipment, are generally called HVAC equipment. The most important component in HVAC equipment is the heat exchange element, which mainly realizes the transfer of heat between two or more fluids through structures such as metal plates, pipes, and tube bundles.

Furthermore, the entire device is easy to inspect and clean, which is conducive to use.

[0004] During use of existing HVAC heat exchange components, since it is necessary to pass the heat medium through the copper tube and transfer the temperature to the metal plate welded on the copper tube, the air passes through the gap between the metal plates to heat the air, thereby completing the heat exchange step. However, in the existing heat exchange process, due to the flow of the medium in the copper tube, the heat is lost in the process of being transferred to the metal plate, and the contact area between the air and the metal plate is limited during the flow, so that the heat cannot be transferred evenly, which reduces the efficiency of air heat lifting, affects the effect of heat exchange, and causes a waste of heat resources.

DETAILED DESCRIPTION

[0032] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0033] The present invention provides Figure 1-9 A high-efficiency HVAC equipment heat exchange component shown includes a fan housing 001, a grille plate 101 is installed on one side of the fan housing 001, and a filter plate 102 is installed on the side of the fan housing 001 away from the grille plate 101;

[0034] The heat exchange component 002 is arranged in the fan housing 001 and is used for heat exchange between the heat medium and the air;

[0035] The high-efficiency control component 003 is arranged in the fan housing 001 and is used to improve the efficiency of air heat exchange.

[0036] Furthermore, in the above structure, the heat exchange component 002 includes a fixing frame 201, which is symmetrically installed on the inner wall of the fan casing 001, and curved tubes 202 are installed in the two groups of fixing frames 201, and one side of the curved tube 202 is connected to the pipeline of the heat medium generating device, and the other side of the curved tube 202 is connected to the pipeline of the heat medium recovery device.

[0037] The curved tube 202 can be firmly fixed in the fan housing 001 by the fixing frame 201 , and the curved tube 202 can transport the heat medium into the fan housing 001 .

[0038] Furthermore, in the above structure, eight groups of heat exchange copper plates 203 are arranged in the fan casing 001, and each group of heat exchange copper plates 203 is integrally penetrated and sleeved with the curved tube 202, and the heat exchange copper plates 203 and the curved tube 202 are fixed by welding, and multiple groups of heat exchange copper plates 203 are arranged and welded in sequence.

[0039] By welding the heat exchange copper plates 203, the heat medium in the curved tube 202 can transfer heat to the heat exchange copper plates 203 during the flow, thereby completing the heat transfer conversion, and the air is transported between the heat exchange copper plates 203, which can heat the air and complete the heat conversion.

[0040] Furthermore, in the above structure, a fixing frame 204 is installed on the inner wall of the fan housing 001 , and the fixing frame 204 is close to one side of the filter plate 102 , and a plurality of sets of fans 205 are installed in the fixing frame 204 .

[0041] The fan 205 can filter the air from the filter plate 102 and allow the air to enter the fan housing 001 , and finally be discharged from the fan housing 001 from the grille plate 101 .

[0042] Furthermore, in the above structure, the high-efficiency control component 003 includes a flow limiting ring 301 , which is installed on the inner wall of the curved tube 202 , and three flow limiting rings 301 form a group, which are respectively arranged in the gap position between each group of heat exchange copper plates 203 .

[0043] The flow rate of the heat medium in the curved tube 202 can be slowed down by the flow limiting ring 301 when passing through the flow limiting ring 301 , thereby extending the residence time of the medium and better transferring the heat to the curved tube 202 and the heat exchange copper plate 203 .

[0044] Furthermore, in the above structure, one side of the heat exchange copper plate 203 is rotatably connected with a corrugated copper plate 302 , and two groups are sequentially installed downward, and the corrugated copper plate 302 is located near the grid plate 101 .

[0045] By setting two groups of corrugated copper plates 302 downward in sequence, the corrugated copper plates 302 can be rotated independently in groups without affecting each other, and the corrugated copper plates 302 can be heated by the excess heat when the air passes through, so that the subsequent air can transfer the heat when passing through the corrugated copper plates 302, and the corrugated copper plates 302 can increase the area of ​​air contact, thereby improving the heat conversion rate.

[0046] Furthermore, in the above structure, a through groove 303 is opened on one side of each group of corrugated copper plates 302, and a slide groove 304 is symmetrically opened on the inner wall of the through groove 303. An internal threaded tube 305 is arranged in the through groove 303, and a slider 306 is symmetrically installed on the internal threaded tube 305, and the slider 306 is slidably connected with the corresponding slide groove 304.

[0047] By setting the slider 306 and the slide groove 304 , the internal threaded barrel 305 can slide while rotating in the through groove 303 .

[0048] Furthermore, in the above structure, a rotating shaft 307 is rotatably connected to the inner wall of the fan housing 001, and opposite threads 308 are symmetrically provided on the surface of the rotating shaft 307, and the threads 308 are grouped in pairs, and four groups are provided in sequence, and each group of threads 308 is screwed with the corresponding internal thread tube 305, and a servo motor 309 is rotatably connected to the outer side of the fan housing 001, and the servo motor 309 is axially connected to the rotating shaft 307, a control box 311 is installed on the outer side of the fan housing 001, and a temperature sensor 312 is linearly connected to one side of the control box 311, and the temperature sensor 312 is connected to the outer side of the fan housing 001, and the control box 311 is linearly connected to each group of servo motors 309, and the control box 311 is linearly connected to the fan 205.

[0049] By opening the threads 308 in groups in opposite directions, the internal threaded tubes 305 can be grouped in pairs and rotated in opposite directions, so that the angle of the corrugated copper plate 302 can be changed, so that the air can contact the corrugated copper plate 302, and the air can be heated in a concentrated manner when flowing, thereby improving the heat conversion rate. The temperature of the environment can be detected by the temperature sensor 312, so that the servo motor 309 can control the angle of each group of corrugated copper plates 302 and control the rotation speed of the fan 205, thereby performing real-time adjustments to achieve the effect of the air environment temperature.

[0050] Furthermore, in the above structure, the heat exchange copper plate 203 is rotatably connected to a guide copper plate 310 on one side away from the wavy copper plate 302, and the guide copper plate 310 is located between the fan 205 and the curved tube 202, and the structure of one side of the guide copper plate 310 is the same as that of one side of the wavy copper plate 302.

[0051] By moving the guide copper plates 310 toward each other, the gap between the guide copper plates 310 is increased to guide the air. At this time, the temperature concentrated in the limiting ring 301 can better heat the air. When the temperature here returns to normal, the openings of the two adjacent groups of guide copper plates 310 can be enlarged by adjusting the guide copper plates 310, thereby increasing the adjacent openings, so that the temperature concentrated in the limiting ring 301 here can also be effectively heated.

[0052] like Figure 1-9 As shown, air is sucked into the fan housing 001 through the fan 205. At this time, heat medium flows in the curved tube 202, thereby performing heat conversion. At the same time, the temperature sensor 312 detects the ambient temperature. When the required temperature is not reached, the angle of the wave copper plate 302 can be changed to reduce the passing gap, and the angle of the opposite guide copper plate 310 can be changed to increase the passing gap, so that the air is more concentrated in the space where the curved tube 202 is located. At this time, due to the effect of the limiting ring 301, the temperature here is higher than other positions, and the air flow is more concentrated, which can make the air temperature rise rapidly, and with the continuous conversion, the temperature here will gradually increase. Gradually returns to normal, at this time the guide copper plate 310 and the corresponding wavy copper plate 302 rotate in opposite directions, so that the openings of the two adjacent groups of guide copper plates 310 are enlarged, and the wavy copper plate 302 is adjusted accordingly, so that the control enters between the two adjacent groups of guide copper plates 310, and the concentrated temperature of the current limiting ring 301 here is relatively high. Through the back and forth conversion, the efficiency of heat conversion is guaranteed to be improved. When the temperature is high or normal, the angle of the guide copper plate 310 and the wavy copper plate 302 can be controlled separately to achieve the effect of controlling the temperature. This structure can effectively improve the efficiency of heat conversion and greatly reduce the energy loss in the heat conversion process, thereby reducing the waste of heat energy.

[0053] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
