The present invention provides a radiant heat exchanger 10 for use in a radiant air conditioning system.
In an embodiment of the present invention, as shown in fig. 1, the radiant heat exchanger 10 includes a heat exchanger plate 100, a connecting rod 200, and a mounting bracket 300. Wherein, the heat exchanging fins 100 are arranged in a plurality and are arranged side by side at intervals; the connecting rod 200 connects a plurality of heat exchange plates 100 in series; one end of the mounting bracket 300 is fixedly connected with the connecting rod 200, and the other end is fixedly connected with the mounting wall.
By arranging a plurality of heat exchange plates 100 arranged side by side at intervals and connecting the plurality of heat exchange plates 100 in series by the connecting rod 200, on one hand, the connection between the heat exchange plates 100 and the connecting rod 200 is realized, and on the other hand, the function of supporting the weight of the plurality of heat exchange plates 100 can be realized; meanwhile, one end of the mounting bracket 300 is fixedly connected with the connecting rod 200, and the other end of the mounting bracket is fixedly connected with the mounting wall, so that the effect of fixedly connecting the connecting rod 200 with the mounting wall is realized. Through the connecting action of the connecting rod 200 and the heat exchange plate 100 and the connecting action of the connecting rod 200 and the installation wall, the connecting action of the heat exchange plate 100 and the installation wall is realized, and the stable installation effect of the radiation heat exchanger 10 is ensured.
Specifically, the cross-sectional shape of connecting rod 200 is not limited, so long as the strength required to support and connect plate 100 is met. For example, the cross-sectional shape of the linkage rod 200 may be circular, triangular, rectangular, or other polygonal shape, etc. When all the heat exchange plates 100 are connected in series, one connecting rod 200 can be adopted and can simultaneously connect all the heat exchange plates 100 in series; a plurality of fins may be used, and each fin may connect all of the fins 100 in series at the same time; multiple tie rods 200 may be used to connect all of the heat exchanger plates 100 in series.
In the technical scheme of the invention, in order to further improve the strength of bearing the weight of the heat exchange plate 100, the preferable scheme is as follows: a plurality of tie rods 200 are arranged in parallel, and each tie rod 200 connects all heat exchanger plates 100 in series.
A plurality of tie rods 200 are connected in series between the plurality of heat exchanger plates 100, and the strength of supporting the weight of the plurality of heat exchanger plates 100 can be further improved by the tie rods 200.
Further, the connecting rod 200 may be made of a metal material, so that the connecting rod 200 made of a metal material can improve the heat conduction efficiency of the whole radiant heat exchanger 10, and the connecting rod 200 made of a metal material can ensure the connection strength of the connection heat exchange fins 100. Of course, in other embodiments, the material of the connecting rod 200 may also be a high polymer material with high strength.
In addition, when the mounting bracket 300 is connected to the mounting wall by the connecting rod 200, the connecting form of the connecting bracket to the mounting wall can be screw connection, anchor bolt connection, or the like; the heat exchanger plate and the connecting rod 200 can be fixedly connected by adopting a screw connection mode, a riveting mode or an adhesion mode and the like, the fixed connection position can be selected from the heat exchange plates 100 on two sides, and the connecting rod 200 part between the two heat exchange plates 100 can also be selected for fixedly connecting.
According to the technical scheme, the plurality of heat exchange plates 100 are arranged side by side at intervals, and the plurality of heat exchange plates 100 are connected in series through the connecting rods 200, so that the integrity of the plurality of heat exchange plates 100 is realized; meanwhile, the mounting bracket 300 is used, one end of the mounting bracket 300 is connected with the connecting rod 200, and the other end of the mounting bracket 300 is fixedly connected with the mounting wall, so that the radiation heat exchanger 10 can be conveniently and integrally mounted on the mounting wall, and the stability of the mounting structure is realized.
On the premise that the mounting bracket 300 can be connected between the connecting rod 200 and the mounting wall, the mounting bracket 300 includes a joint portion 310 sleeved on the outer surface of the connecting rod 200 and a connecting portion 320 fixedly connected with the joint portion 310, and the connecting portion 320 is fixedly connected with the mounting wall.
The joint part 310 of the mounting bracket 300 is sleeved on the outer surface of the connecting rod 200, so that the mounting of workers can be facilitated on the basis of realizing the connecting effect of the mounting bracket 300 and the connecting rod 200, and the assembly efficiency is improved; further, the connection portion 320 fixed to the joint portion 310 is fixedly connected to the mounting wall, whereby the connection function of the mounting bracket 300 and the mounting wall, and further, the connection function of the link 200 and the mounting wall are realized. Since the connecting rod 200 connects a plurality of heat exchanging fins 100 in series, the connecting effect of each part of the whole radiant heat exchanger 10 is achieved, and therefore the connecting effect of the connecting rod 200 and the installation wall enables the whole radiant heat exchanger 10 to be fixedly installed with the installation wall. Of course, in other embodiments, the fixing connection form between the mounting bracket 300 and the connecting rod 200 may not be limited to the sleeving connection, and for example, a fixing splicing connection or a fixing clamping connection may also be adopted.
Specifically, the engaging portion 310 of the mounting bracket 300 may be detachably and fixedly connected to the connecting portion 320, and may also be integrally formed to ensure the fixing connection between the engaging portion 310 and the connecting portion 320. The specific structure of the connection portion 320 is not limited as long as the required connection strength can be satisfied. For example, the connection portion 320 may be configured as a connection plate, and may be configured as a connection hook.
Based on the connection form of the joint 310 and the connecting rod 200, the joint 310 includes a first half ring 311 fastened to the outer surface of the connecting rod 200 and a second half ring 312 fastened to the outer surface of the connecting rod 200 and fixedly connected to the first half ring 311, and one end of the second half ring 312 is fixedly connected to the connecting portion 320 through a connecting rib 330.
The joint 310 includes a first half ring 311 engaged with the outer surface of the connecting rod 200 and a second half ring 312 fixedly connected to the first half ring 311, the second half ring 312 also engages with the outer surface of the connecting rod 200, such that the fixed connection between the first half ring 311 and the second half ring 312 achieves the effect of the joint 310 being sleeved on the outer surface of the connecting rod 200, thereby achieving the connection between the joint 310 and the connecting rod 200. The joint part 310 has a structure of two half rings, so that it is possible to prevent the joint part 310 and the connecting rod 200 from failing to meet the assembling requirement due to machining error or assembling error. For example, when the outer diameter of the connecting rod 200 is larger than the inner diameter of the connecting portion 310 and the outer surface of the connecting rod 200, the gap between the two half rings can be flexibly adjusted by the two half rings of the connecting portion 310, and the connecting action between the first half ring 311 and the second half ring 312 can be realized through the connecting member, so as to realize the fixed connecting action between the connecting portion 310 and the connecting rod 200.
In addition, one end of the second half ring 312 is fixedly connected to the connecting portion 320 via the connecting rib 330, so that the joint portion 310 of the mounting bracket 300 is fixedly connected to the connecting portion 320.
Of course, in other embodiments, the structure of the joint portion 310 sleeved on the outer surface of the connecting rod 200 may also be an integrally formed structure, and in addition, the joint portion 310 may be provided with a gap, so that in the process of sleeving the joint portion 310 on the outer surface of the connecting rod 200, the connecting rod 200 may be connected between the joint portion 310 and the connecting rod 200 by penetrating the gap, and then the connecting members are used to connect the two end portions where the gap is located, thereby reinforcing the connection effect between the connecting rod 200 and the joint portion 310. Further, the connecting rod 200 may have a hollow structure on the premise that the connecting strength is satisfied and the strength of the heat exchanger plate 100 is received, and the joint 310 may be engaged with the inner surface of the connecting rod 200 to achieve the effect of connecting the joint 310 and the connecting rod 200.
On the basis that the joint part 310 adopts a structure that the first half ring 311 and the second half ring 312 are fixed, in order to realize the connection function of the first half ring 311 and the second half ring 312, one end of the first half ring 311 is provided with a first lug 311a fixedly connected with the connecting rib 330, and the other end is provided with a second lug 311b extending opposite to the first lug 311 a; the end of the second half ring 312 away from the connecting rib 330 is protruded with a flange 312a extending opposite to the connecting rib 330, and the flange 312a is fixedly connected with the second lug 311 b.
The first lug 311a fixedly connected with the connecting rib 330 is arranged at one end of the first half ring 311, and simultaneously, due to the fixed connection function of the connecting rib 330 and the second half ring 312, the connection function between the first half ring 311 and the second half ring 312 is realized. In addition, the other end of the first half ring 311 is provided with a second lug 311b extending opposite to the first lug 311a, the end of the second half ring 312 away from the connecting rib 330 is provided with a flange 312a extending opposite to the connecting rib 330, and the flange 312a is fixedly connected with the second lug 311b, so that the fixed connection effect of the first half ring 311 and the second half ring 312 is further realized. Meanwhile, the first lug 311a, the second lug 311b and the flange 312a can meet the connection strength of the first half ring 311 and the second half ring 312 on the premise of meeting the connection requirement of the first half ring 311 and the second half ring 312, so that the first half ring 311 and the second half ring 312 are stably connected.
Further, the radiant heat exchanger 10 further includes two side plates 400 disposed at an interval, the plurality of heat exchanger fins 100 are sandwiched between the two side plates 400, and the side plates 400 are fixedly connected to the connection rod 200.
The heat exchanger plate 100 is clamped between the two side plates 400 connected to the two ends of the connecting rod 200, so that the stability of the heat exchanger plate 100 can be further ensured, and the transportation and installation processes of the radiation heat exchanger 10 can be facilitated.
In the above radiation heat exchanger 10 having the two side plates 400, both ends of the connecting rod 200 abut on the plate surfaces of the two side plates 400 facing each other.
In this embodiment, the two ends of the connecting rod 200 are abutted to the opposite surfaces of the two side plates 400, so that the connecting position between the mounting bracket 300 and the connecting rod 200 is ensured to be located between the two side plates 400, and the appearance of the whole radiant heat exchanger 10 is more concise and elegant.
The present invention further includes another embodiment, which is different from the previous embodiment in that: the connecting rod 200 is connected between the two side plates 400, the end of the connecting rod 200 penetrates through the side plates 400, and the mounting bracket 300 is fixedly connected with the end of the connecting rod 200.
In this embodiment, the connecting rod 200 is connected between the two side plates 400 and the end portion thereof penetrates through the side plates 400, such that the two end portions of the connecting rod 200 are exposed outside the side plates 400; meanwhile, the mounting bracket 300 is fixedly connected with the end of the connecting rod 200, so that the mounting bracket 300 is also exposed outside the side plate 400, thereby on one hand, avoiding a mounting worker from touching the heat exchanger fin 100 in the mounting process, ensuring that the heat exchanger fin 100 is in a nondestructive state, and on the other hand, facilitating the worker to directly and fixedly mount the radiation heat exchanger 10 and the mounting wall.
On the premise of ensuring the normal operation of the radiation heat exchanger 10, in order to avoid that the installation surface of the installation wall is affected with damp when condensed water appears on the heat exchange fin 100 in the refrigeration mode, in the technical scheme of the invention, the radiation heat exchanger 10 is further provided with a back plate 700 clamped between the heat exchange fin 100 and the installation wall, and the back plate 700 can be fixedly connected with the side plate 400 and also can be fixedly connected with the connecting rod 200, so that the fixed connection effect of the back plate 700 and the heat exchange fin 100 is realized, and the fixed connection of all the components of the whole radiation heat exchanger 10 is ensured. Specifically, the heat exchanging fins 100 and the back plate 700 may be disposed in parallel or at an included angle. Considering that the overall size of the radiant heat exchanger 10 is not too large, it is preferable that the heat exchanger plate 100 and the back plate 700 form an included angle.
Further, the radiation heat exchanger 10 further includes a bottom plate 500 having a through hole 510, and the bottom plate 500 is fixedly connected with the side plate 400.
The function of protecting the radiation heat exchange plate 100 can be further realized by arranging the chassis 500 fixedly connected with the side plate 400; meanwhile, the through hole 510 is formed in the base plate 500, so that when condensed water is accumulated on the radiation heat exchange plate 100, the condensed water can flow into an external water receiving tank or a water receiving pipe through the through hole 510 in the base plate 500 under the action of gravity, and the condensed water generated on the radiation heat exchange plate 100 is prevented from directly flowing to the ground to influence the living environment of a user.
In the case of fixedly connecting the entire radiation heat exchanger 10 to the installation wall, in order to prevent the radiation heat exchanger 10 from falling off the installation wall due to insufficient fatigue strength, the radiation heat exchanger 10 further includes legs 600 for supporting the weight of the entire radiation heat exchanger 10, thereby improving the stability of the entire radiation heat exchanger 10.
Specifically, the support legs 600 are fixedly connected to the radiant heat exchanger plate 100. In this way, the feet 600 can support the weight of the entire radiant heat exchanger 10 on the one hand, thereby ensuring the stability of the radiation heat exchanger 10 in placement; on the other hand, the heat exchange plate can be directly contacted with the radiation heat exchange plate 100 to be subjected to heat transfer, so that the heat exchange path is increased.
Of course, the supporting legs 600 can also be fixedly connected to the connecting rods 200, the side plates 400 or the bottom plate 500, and can all function to support the whole radiation heat exchanger 10, thereby improving the stability of the radiation heat exchanger 10.
Further, the heat exchanger plate 100 includes a plurality of hollow pipes 110 for flowing the working fluid and side wings 120 protruding from outer surfaces of both sides of the pipes 110.
The structure enables the working medium to absorb or release heat to the surrounding air in the process of changing the physical state of the working medium when passing through the hollow pipeline 110, so that the temperature of the pipeline 110 is reduced or increased relative to the temperature of the outside air; then, because the outer surface of the pipe 110 is convexly provided with the side wing 120, the temperature of the side wing 120 also reaches the same temperature or the similar temperature as the temperature of the pipe 110 through the heat conduction function of the pipe 110; finally, the wings 120 and the duct 110 both achieve a moderate heat exchange effect by radiating themselves to make the indoor air reach a proper temperature.
Specifically, the side wings 120 are wave-shaped curved plates. The wavy curved plate is adopted by the side wing 120, so that the contact area between the side wing 120 and the outside air is increased, and the heat exchange effect and the heat exchange efficiency of the side wing 120 are enhanced. In addition, the duct 110 may be provided in plurality. By providing a plurality of tubes 110, the volume of the working fluid flowing through the tubes 110 at a time can be doubled, thereby improving the heat exchange efficiency of the radiation heat exchanger 10.
On the premise that the above-mentioned side wing 120 is a curved plate, further, the side wing 120 includes a flat plate portion 121 and a plurality of convex ribs 122 protruding on the plate surface of the flat plate portion 121; on the same plate surface of the flat plate part 121, the distance L between the center lines of two adjacent convex ribs 122 is less than or equal to 2.5 mm.
The side wings 120 comprise a flat plate part 121 and a plurality of convex ribs 122 convexly arranged on the surface of the flat plate part 121, so that the surface area of the side wings 120 is greatly increased, the heat exchange efficiency is further improved, and a better heat exchange effect is achieved. Meanwhile, the distance L between two adjacent ribs 122 is set to be less than or equal to 2.5 mm. Thus, the convex ribs 122 convexly arranged on the flat plate part 121 are more compact, thereby realizing larger heat exchange area and obtaining better heat exchange effect.
Further, the cross-sectional profile of the rib 122 is a circular arc, and the diameter D of the circle on which the circular arc is located is 2 mm. The cross-sectional profile of the rib 122 is an arc, so that the rib 122 can be conveniently processed, and the rib 122 has an arc on the other hand, so that the rib 122 can be smoothly touched, and the phenomenon that a worker is scratched by the rib 122 due to the fact that the worker touches the rib 122 when assembling or disassembling the radiation heat exchanger plate 100 is avoided. The diameter D of the circle where the circular arc is located is set to be 2mm, so that the cross-sectional area of the convex ribs 122 is smaller, the surfaces of the side wings 120 are folded when the plurality of convex ribs 122 are gathered together for arrangement, the surface area is larger, and a larger heat exchange area is provided, so that a better heat exchange effect is realized.
Under the condition of meeting the installation condition of a common household, in order to ensure that the heat exchange efficiency is as high as possible, the size range of the overall diameter of the pipeline 110 is 4-32 mm;
the range of the wall thickness of the pipeline 110 is 0.1 mm-3.0 mm;
the length of the conduit 110 is within 2500 mm.
The overlarge outer diameter of the pipeline 110 may cause the overall size of the heat exchanger plate 100 to be too large, and it is difficult to meet indoor installation scenarios; the pipe 110 has an excessively small outer diameter, and it may be difficult to ensure a good heat exchange effect. The overall diameter of the pipeline 110 in the technical scheme of the invention is between 4mm and 32mm, so that the pipeline 110 can ensure that enough working medium flows in the inner wall of the pipeline on one hand, and further ensure the heat exchange effect between the working medium and the pipeline 110; on the other hand, the condition of indoor installation of the family can be ensured. Meanwhile, the wall thickness of the pipe 110 also affects the heat exchange effect, the strength of the pipe 110 is difficult to ensure when the wall thickness of the pipe 110 is too small, and the heat exchange rate is affected when the wall thickness of the pipe 110 is too large; therefore, in the technical scheme of the invention, the wall thickness of the pipeline 110 is between 0.1mm and 3.0mm, and on one hand, when working medium flowsThe pipe 110 can have certain strength, the reliability of heat exchange is ensured, and the heat exchange rate is prevented from being influenced because the wall thickness of the pipe 110 is not too thick; the length of the pipe 110 is within 2500mm, so that the pipe 110 can also adapt to the size of an indoor room of a common household on the premise of ensuring that certain heat exchange requirements can be met, and the radiation heat exchange fins 100 are prevented from being overlarge in size and not being damagedPreferably indoorsThe possibility of installation.
The invention further provides an air conditioning system, which comprises a host system and the radiation heat exchanger 10, wherein the radiation heat exchanger 10 is connected with the host system. The specific structure of the radiation heat exchanger 10 refers to the above embodiments, and since the air conditioning system adopts all technical solutions of all the above embodiments, at least all the beneficial effects brought by the technical solutions of the above embodiments are achieved, and no further description is given here. The main system of the air conditioning system is composed of a compressor, a heat exchanger, a control assembly and the like, and is installed outdoors, and the radiation heat exchanger 10 is installed indoors.
When the air conditioning system is refrigerating, the compressor, the heat exchanger and the radiation heat exchanger 10 of the indoor unit in the main machine system are connected to form a circulation loop through a conveying channel through which a refrigerant flows. The refrigerant is compressed into high-temperature and high-pressure gas by a compressor, and then enters a heat exchanger to be changed into low-temperature liquid; at this time, the refrigerant in liquid state is decompressed by the throttling device, enters the outdoor heat exchanger through the conveying channel connected with the pipeline 110 in the indoor radiation heat exchanger 10, and is then conveyed into the pipeline 110 of the radiation heat exchanger 10 through the conveying channel, and the refrigerant evaporates and absorbs heat in the pipeline 110, so that the temperature of the surface of the pipeline 110 is reduced. So that the indoor air reaches a proper temperature by performing radiant heat exchange with the external environment through the duct 110 and the wings 120 connected to the duct 110.
When the air conditioning system heats, the same medium as that used for cooling can be used, and heat media capable of transferring heat such as hot water, heat transfer oil and the like can be used to realize the heat exchange process between the pipeline 110 and the outside air. When the same medium is used for cooling, the heating process is different from the cooling process in that: after the refrigerant is compressed into high-temperature and high-pressure gas by the compressor, the refrigerant enters the pipe 110 of the indoor radiation heat exchanger 10 and then enters the heat exchanger of the outdoor unit. The refrigerant is condensed and released to form a liquid state when entering the pipe 110 of the indoor radiation heat exchanger 10, so that the surface temperature of the pipe 110 is raised, and finally, the refrigerant exchanges heat with the external environment through the pipe 110 and the side wings 120 connected with the pipe 110, so that the effect of radiating heat to the external is achieved. When hot water, heat transfer oil and other heat media are used, the host system may use a water pump to deliver the heat media to the pipe 110, and then radiate the heat outwards through the pipe 110 and the side wings 120 connected to the pipe 110.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
