Description

Technical Field

[0001] The utility model belongs to the technical field of heat exchange equipment, and particularly relates to an integrated coil heat exchanger. Background Art

[0002] A heat exchanger (also known as a heat exchanger or heat exchange equipment) is used to transfer heat from a hot fluid to a cold fluid, that is, a device that uses a temperature difference to exchange heat. A heat exchanger is a traditional general-purpose product, and heat exchangers are indispensable in the process flows of many manufacturing industries. For example, household appliances such as water heaters, refrigerators, and air conditioners used in people's daily lives all require heat exchangers. There are various types of heat exchangers on the market. For example, the common coil heat exchanger that we often see is still the mainstream on the market at present because of its simple structure and convenient use.

[0003] However, for common coil heat exchangers, generally, a single-channel flow method is usually used for heat exchange. For example, for a coil heat exchanger disclosed in Chinese Patent CN104697362B, as can be seen from the attached drawings disclosed therein, this kind of coil is mainly wound in a conventional manner from bottom to top (or from top to bottom), and a medium inlet and a medium outlet are provided at both ends of the pipe. From the inlet to the outlet, there is only one channel for the fluid to flow through. And because the height of this kind of spirally wound coil itself is relatively large, that is, the distance from the inlet to the outlet is relatively long, and heat will be continuously absorbed during the process of medium flow, so there is often a situation where the temperature near the inlet end is relatively high and the temperature near the outlet end is relatively low. Then, this single-channel flow method will result in uneven heat exchange effect and slow heat exchange efficiency.

[0004] Therefore, it is necessary to improve the deficiencies of the existing technology and provide an integrated coil heat exchanger that can use a multi-channel method for medium flow to exchange heat, so as to improve the heat exchange efficiency and make the heat exchange effect more uniform.

Therefore, it will not be described in detail in this embodiment.

[0028] Such as Figures 1-6As shown in the figure, this embodiment provides an integrated coil heat exchanger, which includes a housing 1 and a heat exchange coil 2. A cavity 10 for liquid circulation is provided inside the housing 1, and an inlet pipe 11 and an outlet pipe 12 communicating the cavity 10 with the outside are provided on the housing 1; the heat exchange coil 2 is located inside the cavity 10, and the heat exchange coil 2 includes a medium inlet pipe 20, a medium outlet pipe 21 and a heat exchange tube assembly 22. The medium inlet pipe 20 is communicated with the medium outlet pipe 21 through the heat exchange tube assembly 22. A first through hole 13 and a second through hole 14 are also provided on the housing 1. The inlet end 204 of the medium inlet pipe 20 and the outlet end 213 of the medium outlet pipe 21 can extend out of the housing 1 through the first through hole 13 and the second through hole 14 respectively; there are multiple groups of heat exchange tube assemblies 22, and multiple groups of heat exchange tube assemblies 22 are connected in parallel between the medium inlet pipe 20 and the medium outlet pipe 21. In this embodiment, the heat exchange coil 2 can be made of stainless steel, or titanium tube, or copper tube; the housing can be made of stainless steel, with a smooth surface and not easy to hide dirt. Of course, this is only an example here and does not represent a limitation to it. The integrated coil heat exchanger provided by the present utility model is suitable for the use of hot water tanks and also suitable for heat exchange of chillers, etc., and has a relatively wide application field.

[0029] For the integrated coil heat exchanger provided by the present utility model, its specific working process is as follows:

[0030] During use, liquid (such as water) is poured into the cavity 10 through the inlet pipe 11. At the same time, a medium (such as refrigerant or hot water, mainly for the purpose of forming a temperature difference between the liquid and the medium to achieve heat conversion) is input into the heat exchange coil 2 through the inlet end 204 of the medium inlet pipe 20. At this time, the medium flows in the medium inlet pipe 20, then flows through the heat exchange tube assembly 22 and through the medium outlet pipe 21. And by arranging multiple groups of heat exchange tube assemblies 22 in parallel between the medium inlet pipe 20 and the medium outlet pipe 21, after the medium enters the medium inlet pipe 20, there are not only a single channel to flow to the medium outlet pipe 21, but multiple channels can be formed between the medium inlet pipe 20 and the medium outlet pipe 21 for circulation. Specifically, after the medium enters the medium inlet pipe 20, it can be diverted into each heat exchange tube assembly 22 and finally flow to the medium outlet pipe 21 for discharge; during the circulation process, the heat carried by the medium is absorbed by the liquid in the cavity 10, thus completing the heat exchange process. Finally, the medium is discharged from the outlet end 213 of the medium outlet pipe 21, and the heat-exchanged liquid is discharged through the outlet pipe 12; threads are provided in both the inlet pipe 11 and the outlet pipe 12 for threaded connection with external equipment, which is convenient for connection.

[0031] The integrated coil heat exchanger provided by the present utility model has the following beneficial effects compared with the existing ones:

[0032] By arranging multiple groups of heat exchange tube assemblies 22 in parallel between the medium inlet pipe 20 and the medium outlet pipe 21, the function of shunting the medium during the flow process is realized, so that after the medium enters the medium inlet pipe 20, there are multiple different channels that can flow to the medium outlet pipe 21. Compared with the traditional single-channel flow mode, it has the effects of higher heat exchange efficiency and more uniform heat exchange.

[0033] Reference Figure 2 and 4 In a preferred embodiment, a plurality of first connection holes 201 and a plurality of second connection holes 210 are respectively formed in the medium inlet pipe 20 and the medium outlet pipe 21. The plurality of first connection holes 201 and the plurality of second connection holes 210 are respectively arranged at intervals along the circumferential direction of the medium inlet pipe 20 and the medium outlet pipe 21; the heat exchange tube assembly 22 includes an inlet pipe 220 and an outlet pipe 221 that are connected and communicated. The inlet pipe 220 can be communicated with the medium inlet pipe 20 through the first connection hole 201, and the outlet pipe 221 can be communicated with the medium outlet pipe 21 through the second connection hole 210. Reference Figure 4 A plurality of first connection holes 201 are formed in the medium inlet pipe 20. The first connection holes 201 are mainly used to communicate the inside and outside of the medium inlet pipe 20. The plurality of first connection holes 201 are arranged around the pipe body of the medium inlet pipe 20, which can save installation space to a certain extent; the structure and function of the second connection hole 210 are the same as those of the first connection hole 201, and will not be elaborated here. During use, one end of the inlet pipe 220 is communicated with the medium inlet pipe 20 through the first connection hole 201, and the other end of the inlet pipe 220 extends outward relative to the medium inlet pipe 20. One end of the outlet pipe 221 is communicated with the medium outlet pipe 21 through the second connection hole 210, so as to realize the mutual connection between the medium inlet pipe 20, the heat exchange tube assembly 22 and the medium outlet pipe 21; in this embodiment, the structures of the inlet pipe 220 and the outlet pipe 221 are the same. By arranging a plurality of first connection holes 201 and second connection holes 210, it is convenient to install a plurality of heat exchange tube assemblies 22, and further realizes the formation of multiple channels for circulation between the medium inlet pipe 20 and the medium outlet pipe 21, further improving the heat exchange efficiency.

[0034] Reference Figure 2 and 3, in a preferred embodiment, the heat exchange tube assembly 22 further includes a connecting pipe 222. One end of the connecting pipe 222 is connected to the inlet pipe 220, and the other end is connected to the outlet pipe 221. Or, the inlet pipe 220 and the outlet pipe 221 are communicated through the connecting pipe 222; the medium inlet pipe 20, the inlet pipe 220, the connecting pipe 222, the outlet pipe 221, and the medium outlet pipe 21 are sequentially communicated. At this time, the flow direction of the medium is as follows: the medium enters its interior through the inlet end 204 of the medium inlet pipe 20, then flows through the inlet pipe 220 into the connecting pipe 222, and finally flows through the outlet pipe 221 into the medium outlet pipe 21, and thus is discharged to the outside from the outlet end 213 of the medium outlet pipe 21, and circulates in this way.

[0035] Reference Figure 3 , in a preferred embodiment, the heat exchange tube assembly 22 includes an inlet pipe 220, an outlet pipe 221, and a connecting pipe 222. Both ends of the connecting pipe 222 are respectively communicated with the inlet pipe 220 and the outlet pipe 221; the inlet pipe 220 and the outlet pipe 221 are also respectively communicated with the medium inlet pipe 20 and the medium outlet pipe 21; there are multiple connecting pipes 222, and the multiple connecting pipes 222 are arranged at intervals along the length directions of the inlet pipe 220 and the outlet pipe 221. Reference Figure 3 , the inlet pipe 220 and the outlet pipe 221 are arranged at intervals, and both ends of the connecting pipe 222 are respectively communicated with the inlet pipe 220 and the outlet pipe 221. Specifically, a plurality of mounting holes are opened on the side walls of the inlet pipe 220 and the outlet pipe 221, and the plurality of mounting holes are arranged at intervals along the length direction of the inlet pipe 220 / outlet pipe 221; both ends of the connecting pipe 222 can be communicated with the inlet pipe 220 and the outlet pipe 221 through the mounting holes; that is, the connecting pipes 222 are arranged at different heights of the inlet pipe 220 and the outlet pipe 221, so that when the medium flows through the inlet pipe 220, it can be further divided into each connecting pipe 222 to improve the heat exchange efficiency and achieve the effect of uniform heat exchange. Further, the inlet pipe 220, the outlet pipe 221, and the connecting pipe 222 can be integrally formed to improve the overall sealing performance of the heat exchange tube assembly 22 and avoid leakage during the flow of the medium.

[0036] Reference Figure 3 , in a preferred embodiment, the connecting pipe 222 is bent into an arc shape from one end to the other end. By bending the connecting pipe 222, the overall volume of the coil can be further compressed, saving the installation space.

[0037] Reference Figure 4 and 6, in a preferred embodiment, both the medium inlet pipe 20 and the medium outlet pipe 21 are arranged in an annular shape, and the diameter of the inner ring surface of the medium inlet pipe 20 is greater than the diameter of the outer ring surface of the medium outlet pipe 21; alternatively, the diameter of the outer ring surface of the medium inlet pipe 20 is less than the diameter of the inner ring surface of the medium outlet pipe 21. Refer to Figure 6 , taking the medium inlet pipe 20 as an example, the so-called diameter of the inner ring surface is the Figure 6 diameter represented by d1 in Figure 6 , and the so-called diameter of the outer ring surface is the Figure 6 diameter represented by d2 in Figure 6 . It can be seen from

[0038] that the medium inlet pipe 20 and the medium outlet pipe 21 are arranged in a large-small combination; and since both ends of the heat exchange tube assembly 22 are respectively connected to the medium inlet pipe 20 and the medium outlet pipe 21, through this large-small combination, when installing the heat exchange tube assembly 22, it can be in a state of converging towards the middle (refer to Figure 4 , from this top view angle, it is in a state of spiraling outwards), so that the overall volume of the heat exchange coil 2 will be relatively small, saving a certain amount of installation space; in this embodiment, the larger pipe can also be used as the medium outlet pipe, and the smaller pipe can also be used as the medium inlet pipe, that is, the two can be interchanged without limitation.

[0039] Refer to Figure 5, in a preferred embodiment, the housing 1 includes an outer housing 15 and a connecting column 16. The connecting column 16 is of a hollow structure. The two ends of the connecting column 16 are respectively connected to the top and bottom of the outer housing 15. A cavity 10 is formed between the outer wall of the connecting column 16 and the inner wall of the outer housing 15. The liquid inlet pipe 11 and the liquid outlet pipe 12 are respectively arranged on the outer housing 15 at intervals. Specifically, the connecting column 16 is of a hollow cylindrical structure. The two ends of the connecting column 16 are respectively connected to the top and bottom of the outer housing 15. During use, since the inlet ends 204 of the liquid inlet pipe 11, the liquid outlet pipe 12, the medium inlet pipe 20 and the outlet end 213 of the medium outlet pipe 21 will all be connected to external devices, and during actual use, when liquid is transported into the cavity 10, there will be a certain pressure. When this part of the pressure acts on the top and bottom of the outer housing 15, specifically, it will generate an outward pressure on the top and bottom of the outer housing. At this time, by setting the connecting column 16, a tensile force can be exerted on the top and bottom of the outer housing 15, which is equivalent to offsetting part of the outward pressure, thereby preventing the top and bottom of the outer housing 15 from deforming due to excessive pressure in the cavity 10 (the specific manifestation of deformation is that the top and bottom of the outer housing 15 bulge outwards). In severe cases, it may even cause the weld joints of the outer housing to crack and liquid leakage to occur.

[0040] Reference Figure 1 and 2 , in a preferred embodiment, the housing 1 includes an outer housing 15. The liquid inlet pipe 11 and the liquid outlet pipe 12 are respectively arranged on the outer housing 15 at intervals. An installation seat 17 is further arranged on the outer housing 15. One end of the installation seat 17 is connected to the outer housing 15, and the other end extends outwards relative to the outer housing 15. A fixing hole 170 is formed in the installation seat 17, and the fixing hole 170 runs through the installation seat 17 along the thickness direction. There are multiple installation seats 17, and the multiple installation seats 17 are arranged around the outer housing 15. In this embodiment, by setting the installation seat 17, it is convenient to install and fix the heat exchanger, and the stability of the heat exchanger is improved.

[0041] Reference Figure 5 , in a preferred embodiment, the housing 1 includes an outer housing 15 and a connecting column 16. A cavity 10 is formed between the outer wall of the connecting column 16 and the inner wall of the outer housing 15. The outer housing 15 and the connecting column 16 are integrally formed by welding.
