In the present embodiment, the integrated heat exchange device includes a heat exchange part 100 and a flow guide part 200 which are integrated together. In the heat exchanging part 100, a first medium passage 110 and a second medium passage 120 are formed to be separated from each other. Wherein the second medium passage 120 may be used to communicate with the first heat source. In the embodiments of the present specification, the first heat source is mainly exemplified by a heat pump. The first medium passage 110 may be used to circulate heating water, and the first medium passage 110 may be a partial heating passage of the first heat source.

The second medium channel 120 is a part of the heat exchange medium channel of the first heat source; the second medium passage 120 is configured to allow a heat exchange medium (e.g., a refrigerant) to flow therethrough. When in use, the heat exchange medium in the second medium channel 120 can exchange heat with the heating water in the first medium channel 110 to realize heating or cooling.

The heat exchanging part 100 is matched with the flow guide part 200 to form a flow guide channel, or a flow guide channel is arranged in the flow guide part 200. The flow guide channel is separately disposed in the flow guide part 200, or the flow guide channel is formed by matching the heat exchanging part 100 and the flow guide part 200, and specifically, the formation manner of the flow guide channel may be different according to the specific shape and configuration of the flow guide part 200. For example, referring to fig. 1 to 10, when the flow guiding portion 200 is in the form of a flow guiding groove with an open end, the flow guiding channel may be formed by the heat exchanging portion 100 and the flow guiding portion 200, and referring to fig. 11 to 17, when the flow guiding portion 200 is a relatively closed hollow cavity, the flow guiding channel may be formed inside the flow guiding portion 200.

The position of the first medium outlet joint 130 can be determined comprehensively according to a specific application scene of the integrated heat exchange device, and multiple factors such as arrangement of heating water pipes and convenience of installation.

For example, when the integrated heat exchanger and the combustion heat exchanger 5 (e.g., a wall-hanging stove) are integrally disposed in one housing 4, the first medium outlet connector 130 may be inserted into the top of the housing 4, so as to directly guide the heating water out by using the first medium outlet connector 130.

On the whole, for prior art, the integrated heat transfer device that provides in this application specification utilizes this integration to set up in water conservancy diversion portion 200 or the integrated water conservancy diversion passageway that sets up between heat transfer portion 100 and water conservancy diversion portion 200 can realize the function of the play water of heating water at least, in addition, can reach and simplify the structure, reduce the volume, save installation space, simplify the installation, reduce cost reduces the water leakage point, the follow-up maintenance of being convenient for.

Specifically, the heat exchange portion 100 may be in the form of a plate heat exchanger. Of course, the heat exchanging part 100 may also be in the form of other heat exchangers. When the heat exchanging part 100 is in the form of a plate heat exchanger, the heat exchanging part 100 may include a plurality of heat exchanging fins stacked one on another. The number of the heat exchange fins can be set according to conditions such as actual heat exchange requirements and the like, and the application is not specifically limited. The heat exchanging part 100 has first and second sides a and B opposite to each other in a second direction Y stacked along the interval of the heat exchange fins, and the flow guide part 200 may be disposed at one side of the heat exchanging part 100. The first media channel 110 has a first media inlet end 111 and a first media outlet end 112; the second media channel 120 comprises a second media inlet end 121 and a second media outlet end 122. The specific location of the flow guide part 200 may be determined according to the fitting relationship with the heat exchange part 100.

Further, the first medium inlet end 111 and/or the first medium outlet end 112 are communicated with the flow guide channel.

Taking the heat exchange portion 100 as a plate heat exchanger as an example, heating water may flow through the first medium passage 110 inside the heat exchange portion 100. The heating water enters the first medium channel 110 from the first medium inlet 111, exchanges heat with the refrigerant in the second medium channel 120, and then flows out through the first medium outlet 112. When the first medium outlet port 112 is communicated with the guide passage, the heating water after heat exchange with the refrigerant may enter the guide passage.

When the first medium inlet port 111 communicates with a guide passage, heating water in the guide passage may enter the first medium inlet port 111.

When the first medium outlet port 112 and the first medium inlet port 111 are both communicated with the flow guide channel, the flow guide channel may include a plurality of relatively independent portions (for example, a first flow guide channel 210, a second flow guide channel 220, and the like shown in fig. 18), the heating water may enter the first flow guide channel 210 from the first medium outlet port 112, then flow out from the first flow guide channel 210 and enter a heating water main water outlet pipeline (not shown), and after exchanging heat with the heat exchange terminal, flow back to the first medium inlet port 111 through the heating water main water return pipeline (not shown) and the second flow guide channel 220.

When the first medium inlet end 111 is communicated with the diversion channel, the above-mentioned situation that both the first medium outlet end 112 and the first medium inlet end 111 are communicated with the diversion channel can be referred to, that is, the heating water after heat exchange with the heat exchange terminal can enter the heat exchange portion 100 from the first medium inlet end 111 through the heating water main return pipeline and the second diversion channel 220 for heat exchange.

The heat exchanging part 100 may extend lengthwise along a first direction X.

The second medium inlet port 121 may be located at an upper portion of the heat exchanging part 100 to serve as a refrigerant inlet, and the second medium outlet port 122 may be located at a lower portion of the heat exchanging part 100 to serve as a refrigerant outlet. The first media inlet end 111 and the first media outlet end 112 are also arranged in the height direction. In order to ensure high heat exchange efficiency between the first medium and the second medium, the two media flow in opposite directions, a first medium inlet 111 for introducing heating water to be heat-exchanged with a refrigerant may be located at a lower portion of the heat exchanging portion 100, and a first medium outlet 112 for discharging heating water heat-exchanged with the refrigerant may be located at an upper portion of the heat exchanging portion 100.

At least a portion of the flow guide portion 200 may extend along the first direction X, and specifically, when the flow guide portion 200 at least includes a flow guide channel communicated with the first medium, the portion of the flow guide channel communicated with the first medium may have one end communicated with the first medium outlet port 112 and the other end connected with the first medium outlet joint 130. The first medium outlet joint 130 may be used to connect an outlet pipe for supplying heating water to the heat exchange terminal. When the first medium outlet port 112 and the first medium outlet connector 130 are both disposed near the upper portion of the heat exchanging part 100, the flow guiding part 200 may extend along the first direction X from top to bottom, and then extend along the first direction X from top to bottom, so as to form a U-shaped flow channel shown in the drawing. Of course, the specific shape and structure of the flow guide portion 200 are not limited to the examples of the present specification and the drawings, and may be determined comprehensively according to the shape of the actual heat exchanging portion 100, the position of the joint, and the like.

The different structures and forming manners of the flow guide portion 200 will be described in a classification manner with reference to the accompanying drawings.

The specific shape and configuration of the diversion trench can be matched according to the function required to be realized.

In order to ensure that a sealed flow guide channel is formed between the flow guide part 200 and the heat exchange part 100, the flow guide part 200 and the heat exchange part 100 are integrated by welding. When the flow guide part 200 and the heat exchange part 100 are integrated by welding, the welding process may include a brazing process. The flow guide part 200 is disposed on the first side a of the heat exchanging part 100, and a solder is disposed between two adjacent heat exchanging fins and between the side of the flow guide part 200 where the opening is disposed and the first side a of the heat exchanging part 100.

The diversion part 200 and the heat exchange part 100 may be connected by a sealing flange, and the sealing connection between the diversion part 200 and the heat exchange part 100 is not limited to the above example, as long as reliable sealing and fixing of the diversion part 200 and the heat exchange part 100 can be achieved.

In this specification, the second media passage 120 includes a second media inlet end 121 and a second media outlet end 122. Wherein the flow guide part 200 and the second medium inlet end 121 and/or the second medium outlet end 122 may be located at the same side of the heat exchanging part 100.

In the present embodiment, the flow guide portion 200 may be located on the same side of the heat exchanging portion 100 as at least one of the second medium inlet end 121 and the second medium outlet end 122, for example, the first side a of the heat exchanging portion 100. In this specification, the second medium inlet port 121 may be a refrigerant inlet port, and the second medium outlet port 122 may be a refrigerant outlet port. When the flow guide part 200 and at least one of the inlet end and the outlet end of the refrigerant are positioned on the same side, the refrigerant pipeline is favorably and reasonably arranged or integrated subsequently. In the following embodiments, the flow guide portion 200, the second medium inlet port 121, and the second medium outlet port 122 are mainly located on the first side a of the heat exchanging portion 100.

The second medium outlet end 122 may also be provided with a second medium outlet extension joint, which may be a length extension formed on the second medium outlet end 122, such as a hollow joint. The second media inlet port 121 and/or the second media outlet port 122 may pass through the flow guide 200 through a joint. The length of the joint may be greater than the thickness of the guide portion 200, so that a protrusion portion for connecting a refrigerant pipe is formed after penetrating through the guide portion 200.

As shown in fig. 7 and 10, the present embodiment is mainly different from the first embodiment in that: a spacer 215 is arranged between the second medium inlet extension joint and/or the second medium outlet extension joint and the flow guide 200. The partition 215 disposed between the second medium inlet extension joint and/or the second medium outlet extension joint and the guide part 200 is used to separate the refrigerant from the heating water in the guide part 200, thereby preventing the refrigerant from exchanging heat with the heating water in the guide part 200.

Specifically, the partition 215 may be a cavity formed on the flow guide portion 200, the second medium inlet extension joint and/or the second medium outlet extension joint are/is located in the cavity, and an annular gap is formed between the second medium inlet extension joint and/or the second medium outlet extension joint and the cavity; alternatively, the spacer 215 may be a sleeve pipe sleeved on the second medium inlet extending joint and/or the second medium outlet extending joint, and an annular gap is formed between the sleeve pipe and the joint, so as to prevent the refrigerant from exchanging heat with the heating water in the flow guide portion 200. Of course, the specific form of the partition 215 is not limited to the above examples, for example, the partition 215 may also be provided with a thermal insulation layer and the like on the second medium inlet extending joint and/or the second medium outlet extending joint, and the application is not limited in this respect.

In addition, in order to prevent the refrigerant from exchanging heat with the heating water in the guide part 200, in another embodiment, the second medium passage 120 includes a second medium inlet port 121 and a second medium outlet port 122, and the guide part 200 and the second medium inlet port 121 and/or the second medium outlet port 122 are located at different sides of the heat exchanging part 100.

In the present embodiment, when the guide part 200 and the second medium inlet port 121 and/or the second medium outlet port 122 are located at different sides of the heat exchanging part 100, for example, when the guide part 200 is located at the first side a of the heat exchanging part 100 and the second medium inlet port 121 and/or the second medium outlet port 122 is located at the second side B of the heat exchanging part 100, the refrigerant flowing in from the second medium inlet port 121 or the refrigerant flowing out from the second medium outlet port 122 is separated from the heating water in the guide part 200 by the heat exchanging part 100, and thus the heat exchange between the refrigerant and the heating water in the guide part 200 can be prevented.

Referring to fig. 11, 12, 13, 14, 15, 16 and 17, in the third embodiment, the flow guide channel is formed only by the inner cavity of the flow guide part 200.

As shown in fig. 17, the flow guide part 200 may be a hollow housing 4, a cavity is formed in the housing 4, and a flow guide channel is formed only by the inner cavity of the flow guide part 200.

Specifically, a connection portion matched with the first medium inlet end 111 and/or the first medium outlet end 112 is disposed at one side of the flow guide portion 200 facing the heat exchanging portion 100, and one side of the flow guide portion 200 at which the connection portion is disposed is in butt contact with the first side a of the heat exchanging portion 100.

In this embodiment, the first side a of the heat exchange portion 100 may be provided with the first medium inlet port 111 and/or the first medium outlet port 112. The first media inlet end 111 and/or the first media outlet end 112 may particularly be in the form of openings. The side of the flow guiding part 200 facing the heat exchanging part 100 is provided with a connecting part, which may be in the form of an opening, but may also be in other connecting forms provided with an opening. When the guide part 200 is butted with the heat exchange part 100, the first medium outlet 112 is matched with the connection part, and the heating water flowing out of the first medium outlet 112 can flow into the guide part 200.

As shown in fig. 18, in the fourth embodiment, the guide portion 200 may be formed by injection molding. The connecting part is connected with the first medium inlet end 111 and/or the first medium outlet end 112 through a connecting piece.

In the present embodiment, the flow guide portion 200 may be formed by injection molding, and when the flow guide portion 200 is formed by injection molding, the flow guide portion 200 is integrally formed as an injection molded part. Of course, the flow guide portion 200 may also be manufactured by other processing and forming manners, and correspondingly, the material of the flow guide portion 200 may also be different according to different processing and forming manners, which is not listed herein. Wherein the connecting piece may be in the form of a connecting joint. The connection may be connected with the first media inlet port 111 and/or the first media outlet port 112 by a connection joint.

In one embodiment, the preset position of the connection comprises a first medium outlet connection 130, the flow guiding channel comprises at least a first flow guiding channel 210 for communicating the first medium channel 110, the first flow guiding channel 210 is for communicating the first medium outlet end 112 and the first medium outlet connection 130.

In the present embodiment, the joint at the preset position includes a first medium outlet joint 130, and the first medium outlet joint 130 may be a heating water outlet joint. The flow guide channel at least includes a first flow guide channel 210, and the first flow guide channel 210 may be a heating water outlet channel, and is used for communicating the first medium outlet port 112 and the first medium outlet connector 130.

Referring to fig. 18, in the fourth embodiment, the joint at the preset position may further include a first medium inlet joint 140, the flow guide channel further includes a second flow guide channel 220 for communicating the first medium, and the second flow guide channel 220 is used for communicating the first medium inlet end 111 of the first medium channel 110 and the first medium inlet joint 140.

In this embodiment, the joint at the preset position may further include a first medium inlet joint 140, and the first medium inlet joint 140 may be a heating water return joint. The guide passage may further include a second guide passage 220, and the second guide passage 220 may be a heating water return passage for communicating the first medium inlet port 111 and the first medium inlet joint 140.

In one embodiment, the first and second

flow guide passages

210 and 220 are disposed on the same side of the heat exchanging part 100.

In this embodiment, when the first flow guiding channel 210 and the second flow guiding channel 220 are integrated on the same side (for example, the first side a) of the heat exchanging portion 100, it is beneficial to integrate a plurality of flow guiding channels with different functions into the same module, so as to reduce the manufacturing cost and the size of the integrated heat exchanging device, and make the whole integrated heat exchanging device more compact in structure and more convenient to install.

Referring to fig. 19, the flow guide channels may further include a third flow guide channel, one end of the third flow guide channel is communicated with the second medium outlet 122, and the other end of the third flow guide channel is communicated with the second medium outlet connector 150. When the integrated heat exchange device is applied to a composite indoor unit, the second medium outlet joint 150 may lead the refrigerant in the heat exchange portion 100 out of the casing 4, and flow back to the first heat source (e.g., an outdoor unit of a heat pump) through a refrigerant pipeline. In this embodiment, the third diversion channel is a flow channel for guiding the second medium (refrigerant) out of the integrated heat exchange device. When a third flow guide channel is integrated in the flow guide channel, one end of the third flow guide channel is communicated with the second medium outlet end 122, and the other end of the third flow guide channel is communicated with the second medium outlet connector 150, so that a refrigerant guide pipeline can be omitted.

Still further, the flow guide channel may further include a fourth flow guide channel, and the joint at the preset position may further include: and one end of the fourth guide channel is communicated with the second medium inlet end 121, and the other end of the fourth guide channel is communicated with the second medium inlet joint 160.

In this embodiment, the fourth diversion channel is a flow channel for guiding the second medium (refrigerant) into the integrated heat exchange device. When a fourth flow guide channel is integrated in the flow guide channel, one end of the fourth flow guide channel is communicated with the second medium inlet end 121, and the other end of the fourth flow guide channel is communicated with the second medium inlet joint 160, so that a refrigerant introducing pipeline can be omitted. When the integrated heat exchanger is applied to a composite indoor unit, the second medium inlet joint 160 can guide the refrigerant provided by the heat pump outdoor unit into the heat exchanging part 100 in the casing 4.

In the embodiment provided in the present specification, the first flow guide channel 210 is further provided with a first port 201 and a second port 202 for communicating with a third medium channel.

Specifically, the first connector 201 and the second connector 202 may be in the form of threaded holes formed in a cavity wall of the first flow guide channel 210, or the first connector 201 and the second connector 202 may also be in the form of joints hermetically fixed on the cavity wall of the first flow guide channel 210; in addition, the first port 201 and the second port 202 may be formed as joints integrally formed with the cavity wall of the first flow guide channel 210, or may be formed in other forms. In general, the specific form of the first interface 201 and the second interface 202 is not specifically limited in this application.

The third medium channel is used for being communicated with a second heat source, and the third medium channel can be a partial heating channel of the second heat source. The first guide passage 210 is communicated with the first medium passage 110, that is, the heating water of the first medium passage 110 and the heating water of the third medium passage may be mixed in the first guide passage 210. When the water temperatures of the heating water in the first medium passage 110 and the third medium passage are different, for example, the water temperature of the heating water in the first medium passage 110 is lower, and the water temperature of the heating water in the third medium passage is higher, the high-temperature water in the third medium passage can be used to raise the temperature of the outlet water of the heating water in the first medium passage 110. At this time, the first diversion channel 210 or a part of the first diversion channel 210 for mixing two heating water with different temperatures also has a function of coupling a plurality of heating water with different temperatures.

Taking fig. 5, 10, and 18 as an example, the heat exchanging portion 100 extends lengthwise along a first direction X, and the first flow guiding channel 210 may include: the first sub-channel 211 and the second sub-channel 212 are arranged along a width direction Z of the heat exchanging portion 100, and the third sub-channel 213 is used for connecting the first sub-channel 211 and the second sub-channel 212, where the first sub-channel 211 and the second sub-channel 212 extend along the first direction X.

In the present embodiment, the specific arrangement and configuration of the first guide channel 210 may be determined comprehensively according to the width dimension of the heat exchange portion 100, the position of the first medium outlet end 112, the position of the first medium outlet joint 130, and the like.

In order to ensure that the size occupied by the integrated heat exchange device is as small as possible, the height dimension of the integrated heat exchange device coincides with the dimension of the first direction X (height direction) of the heat exchange portion 100 in the first direction X, and the width dimension of the integrated heat exchange device coincides with the dimension of the width direction Z of the heat exchange portion 100 in the width direction Z.

Specifically, the heat exchanging part 100 extends lengthwise along a first direction X, and the first sub-flow passage 211 and the second sub-flow passage 212 extend along the first direction X. The third sub-flow channel 213 is used to connect the first sub-flow channel 211 and the second sub-flow channel 212, and may extend along the width direction Z as a whole.

The first sub-channel 211 is communicated with the first medium outlet end 112. The heating water flowing out of the first medium outlet port 112 flows through the first sub-flow passage 211, the third sub-flow passage 213, and the second sub-flow passage 212 in order along the fluid flow direction.

When the first diversion channel 210 is provided with the first interface 201 and the second interface 202, one interface can be used as a backwater outlet of a second heat source (such as a wall-mounted furnace); one interface may be used as a hot water inlet for a wall-hanging stove.

At least a part of the first sub-flow channel 211, the third sub-flow channel 213 and the second sub-flow channel 212 has a flow channel section with a larger flow cross section than the other sub-flow channels, and the flow channel section is used for forming a coupling part.

In this specification, when the diversion part 200 integrates the function of the coupling part and is integrated with the heat exchanging part 100, the heating water path between the coupling part and the heat exchanging part 100 can be omitted without affecting the water path communication relation, thereby facilitating the simplification of the structure, the reduction of the cost and the reduction of the volume. When the integrated heat exchange device is applied to a heat exchange system, the integrated heat exchange device integrated with the flow guide part 200 of the coupling part and the heat exchange part 100 is further assembled and integrated with other parts, so that a composite internal machine with small volume and low cost can be formed.

The position with a larger flow cross section forms a coupling portion, and the heating water flowing out from the first medium outlet port 112 and the heating water entering the first diversion channel 210 from the first port 201 can be mixed in the coupling portion and finally can be output from the second port 202.

Specifically, the first connector 201 and the second connector 202 may be disposed on the second sub-channel 212; or the first port 201 and the second port 202 may be disposed one on the second sub-flow passage 212 and one on the third sub-flow passage 213; or the first port 201 and the second port 202 may be disposed one in the second sub flow channel 212 and one on the first sub flow channel 211.

In one embodiment, the first port 201 and the second port 202 are both connected to the second sub-channel 212, and the first port 201 and the second port 202 are disposed along the first direction X.

When the first connector 201 and the second connector 202 are both disposed on the second sub-channel 212, a height difference may be formed between the first connector 201 and the second connector 202, for example, the first connector 201 may be higher than the second connector 202. The first port 201 at the upper portion may be used as a return water outlet of a second heat source (e.g., a wall-hanging stove), and the second port 202 at the lower portion may be used as a hot water inlet of the wall-hanging stove. Of course, the functions of the first interface 201 and the second interface 202 can be interchanged, that is, the first interface 201 at the upper part can be used as a hot water inlet of the wall-hanging stove, and the second interface 202 at the lower part can be used as a water return outlet of the wall-hanging stove.

Further, the flow cross sections of the first sub-flow channel 211 and the second sub-flow channel 212 are the same or close to each other, and the flow cross section of the third sub-flow channel 213 is larger than the flow cross section of the first sub-flow channel 211 or the second sub-flow channel 212.

When the flow cross section of the third sub-flow passage 213 is greater than the flow cross section of the first sub-flow passage 211 or the second sub-flow passage 212, when the heating water flows from the position with the smaller flow cross section to the position with the larger flow cross section, the flow rate is reduced, the pressure is reduced, and the third sub-flow passage 213 with the larger flow cross section is used for realizing the function of coupling the heating water, so that a coupling tank can be omitted. In use, the heating water flowing into the first medium passage 110 from the first medium outlet port 112 and the heating water flowing into the first medium passage 110 through one joint (e.g., the first joint 201) may be mixed in the third sub-channel 213; and subsequently can exit the integrated heat exchange device through another port (e.g., second port 202).

In addition, the flow cross section of the second sub flow channel 212 may be larger than that of the first sub flow channel 211. When the flow cross section of the second sub-flow passage 212 is greater than that of the first sub-flow passage 211, the second sub-flow passage 212 or the second sub-flow passage 212 and the third sub-flow passage 213 may perform two functions of coupling heating water.

As shown in fig. 18, in one embodiment, the second diversion passage 220 includes a first diversion subsection 221 and a second diversion subsection 222, and the first diversion subsection 221 and the second diversion subsection 222 are connected in series with any one or a combination of the water pump 3, the flow path detection/control component.

In the present embodiment, the second guide passage 220 may include a first guide sub-portion 221 and a second guide sub-portion 222. Wherein, a water pump 3 may be disposed between the first guide subsection 221 and the second guide subsection 222, and the water pump 3 is used to provide driving force for the heating water to flow back to the heat exchanging part 100. In addition, a flow path detecting member (e.g., a flow rate detecting member), and a control member (e.g., a control valve) may be disposed between the first guide sub-portion 221 and the second guide sub-portion 222. Specifically, the specific components arranged between the first diversion subsection 221 and the second diversion subsection 222 may be different according to the different functions required to be implemented in the specific application scenario of the actual integrated heat exchange device, and this application is not given as an example.

In one embodiment, the heat exchanging part 100 extends lengthwise along a first direction X, and the heat exchanging part 100 has a first end and a second end opposite to each other along the first direction X, and the first medium outlet joint 130 and the first medium inlet joint 140 are located at the first end of the heat exchanging part 100.

In the present embodiment, referring to the description of the above embodiments, taking the heat exchanging part 100 in the installed state as an example, the first direction X of the heat exchanging part 100 may be a height direction, and the heat exchanging part 100 has a first end and a second end opposite to each other, wherein the first end may be a top end of the heat exchanging part 100, and the second end may be a bottom end of the heat exchanging part 100. When the first medium outlet joint 130 and the first medium inlet joint 140 are both located at the first end of the heat exchanging part 100, wherein the first medium outlet joint 130 may be butted with a main heating water outlet pipe, and the first medium inlet joint 140 may be butted with a main heating water return pipe; the heating water main water outlet pipeline and the heating water main water return pipeline connected with the heat exchange part 100 are installed from the top, so that the simplified installation and the reasonable arrangement of subsequent pipelines are facilitated, the pipelines can be connected as far as possible, and particularly unnecessary exposed pipelines are reduced.

Further, the first media outlet end 112 is disposed proximate the first end and the first media inlet end 111 is disposed proximate the second end.

After entering the first medium channel 110 of the heat exchanging part 100 from the first medium inlet end 111, the heating water exchanges heat with the refrigerant in the second medium channel 120; the heating water after heat exchange of the refrigerant enters the diversion part 200 from the first medium outlet end 112; the heating water entering the guide part 200 is mixed with the heating water flowing into the guide part 200 from the first port 201; the mixed heating water may then flow out through the first connection 201 together. A part of the outflow heating water may flow into the combustion heating water outlet pipe 51 for supply to the heat exchange terminal; and the other part of the heating water flows back to the third medium channel to be heated again.

In a specific application scenario, the first medium channel 110 is used for circulating heating water, and the second medium channel 120 is used for circulating a refrigerant; the first flow guide channel 210 is used for communicating the first medium outlet end 112 with a first medium outlet joint 130 for supplying heating water outwards; the second guide channel 220 is used for communicating the first medium inlet end 111 and the first medium inlet joint 140 for receiving return heating water. Wherein the heat exchanging part 100 extends lengthwise along a first direction X and has a first end and a second end opposite to each other, the first medium outlet joint 130 is disposed near the first end of the heat exchanging part 100, and the first medium outlet end 112 is disposed near the first end; the first media inlet connection 140 is disposed proximate the first end.

In the embodiments of the present specification, the integrated heat exchanger is actually installed in a composite internal machine as an example. The lengthwise extending direction (i.e., the first direction X) of the heat exchanging part 100 is arranged along the height direction, the first end of the heat exchanging part 100 is an upper end, and the second end of the heat exchanging part 100 is a lower end. The joint of the preset position of the integrated heat exchanging apparatus may include a joint disposed near the first end of the heat exchanging part 100. Specifically, the joint at the predetermined position may at least include: a first media outlet connection 130 and a first media inlet connection 140.

Taking the integrated heat exchange device installed in a composite internal machine as an example, generally, the composite internal machine is provided with a shell with a predetermined size, a long and narrow space for installing the integrated heat exchange device is formed in the shell, in order to arrange the integrated heat exchange device in the long and narrow space, each originally external pipeline of the integrated heat exchange device can be integrated at one side of the heat exchange part 100, and joints (at least comprising a first medium outlet joint 130 and a first medium inlet joint 140) which need to be connected with the outside are arranged at the upper end as much as possible and are close to the top of the shell 4, so that the structure of the integrated heat exchange device can be simplified to the greatest extent, the volume of the integrated heat exchange device is reduced, and meanwhile, the connection of a plurality of pipelines can be omitted.

As shown in fig. 18, further, when the flow guide part 200 further includes a second flow guide channel 220, the second flow guide channel 220 is a channel for recovering the heating water in the main circuit, and the water pump 3 is disposed on the second flow guide channel 220.

Wherein the water pump 3 is used to provide driving force for the flow of heating water. When the heat exchanging part 100 has a dimensional margin in the width direction Z, at least a portion of the second flow guide channel 220 may be arranged side by side with the first flow guide channel 210. For example, the second guide passage 220 may include a first guide sub-part 221 and a second guide sub-part 222 connected to both sides of the water pump 3, wherein the first guide sub-part 221 may be disposed side by side with the first guide passage 210, and the second guide passage 220 may be located below the first guide passage 210, so that the surface size (i.e., the surface size formed by the height direction and the width direction Z in cooperation) of the heat exchange portion 100 can be maximally utilized.

In addition, the flow guide portion 200 may further include a third flow guide channel (not shown) for circulating a refrigerant, one end of the third flow guide channel is communicated with the second medium outlet 122, the other end of the third flow guide channel is communicated with a second medium outlet connector 150, the second medium outlet 122 is disposed near the second end, and the second medium outlet connector 150 is disposed near the first end.

In this case, the joint at the predetermined position may further include a second medium outlet joint 150, and the refrigerant pipe is also led out through the second medium outlet joint 150 located at the upper portion. When a user installs the air conditioner, the refrigerant pipe and the heating water pipe can be hidden in the suspended ceiling in a top mounting mode, and therefore attractiveness can be improved.

In this embodiment, the composite internal unit is installed in a user room, and can be matched with an external unit of a heat pump to form a heat exchange system. Specifically, the compound internal machine may include: a housing 4, and a combustion heat exchanger 5 and an integrated heat exchanger integrated in the housing 4.

Specific functions, components, structures and technical effects which can be realized of the integrated heat exchange device can refer to the specific description of the embodiment of the integrated heat exchange device, and repeated description is omitted herein.

The combustion heat exchange device 5 may further be provided with a combustion heating water outlet pipe 51 for outputting heating water and a combustion heating water return pipe 52 for receiving the heating water.

The first diversion channel 210 of the integrated heat exchange device is provided with a first interface 201 connected with the combustion heating water return pipe 52 and a second interface 202 connected with the combustion heating water outlet pipe 51. When the combustion heating water outlet pipe 51 is connected to the second connector 202 and the combustion heating water return pipe 52 is connected to the first connector 201, the high-temperature heating water heated by the self-combustion heat exchanging device 5 may enter the first guide flow passage 210 through the first connector 201, be mixed with the heating water from the heat exchanging part 100 in the first guide flow passage 210, and finally flow out through the second connector 202. A part of the heating water flowing out through the second connection port 202 may flow back to the combustion heat exchanging device 5 through the combustion heating return pipe 52, and another part may be supplied to the heat exchanging terminal through the heating main loop. As shown in the drawings, the first port 201 may be located above the second port 202 in the height direction. Of course, in another embodiment, interchanging the positions of the first interface 201 and the second interface 202 is not excluded. Specifically, the housing 4 has a height direction, a width direction Z, and a depth direction which are opposite to each other. For example, the housing 4 may be a hollow box structure having a predetermined size. Wherein a first direction X in which the heat exchanging portion 100 extends lengthwise is aligned with a height direction of the housing 4. The width direction Z of the heat exchanging part 100 may coincide with the width direction Z of the case 4.
