[0004] The technical solutions for achieving the above objectives include the following:

[0005] A heat exchange device includes: a support body, a first heat exchange mechanism, a second heat exchange mechanism, and a centrifugal fan.

The first heat exchange mechanism is at least partially located close to the first heat exchange port, and the second heat exchange mechanism is at least partially located close to the second heat exchange port.

[0006] The centrifugal fan has an air outlet and two air inlets. The air outlet is located on the outer surface of the support body, and the two air inlets are arranged opposite to each other. The two air inlets correspond to the first heat exchange port and the second heat exchange port, respectively.

[0007] In one embodiment, the first heat exchange mechanism includes a first air-side heat exchanger, a first compressor, a first connecting pipe, a first condenser, and a first pipe. The first air-side heat exchanger is installed at a first heat exchange port, and a first air duct is formed between the first air-side heat exchanger and one of the air inlets.

[0008] The first condenser has a first heat exchange chamber and a second heat exchange chamber, which are separated from each other. The first air-side heat exchanger, the first compressor, and the first heat exchange chamber are connected by a first connecting pipe to form a first temperature regulator. The second heat exchange chamber is connected to a first pipe.

[0009] In one embodiment, the second heat exchange mechanism includes a second air-side heat exchanger, a second compressor, a second connecting pipe, a second condenser, and a second pipe. The second air-side heat exchanger is installed at a second heat exchange port, and a second air duct is formed between the second air-side heat exchanger and another air inlet.

[0010] The second condenser has a third heat exchange chamber and a fourth heat exchange chamber, which are separated from each other. The second air-side heat exchanger, the second compressor, and the third heat exchange chamber are connected by a second connecting pipe to form a second temperature regulator. The fourth heat exchange chamber is connected to a second pipe.

[0011] In one embodiment, the first pipe is an inlet pipe and the second pipe is an outlet pipe. The inlet pipe is connected to the first end of the second heat exchange chamber and the fourth heat exchange chamber, and the outlet pipe is connected to the second end of the second heat exchange chamber and the fourth heat exchange chamber.

[0012] In one embodiment, both the first temperature regulator and the second temperature regulator are provided with a throttle valve.

[0013] In one embodiment, the air inlet is perpendicular to the air outlet.

[0014] In one embodiment, the support body includes an outer shell and an inner shell. An installation cavity is formed inside the outer shell, and the inner shell is installed inside the installation cavity, separating the installation cavity to form a first receiving cavity and a second receiving cavity. The first heat exchange mechanism and the second heat exchange mechanism are disposed in the first receiving cavity, and the centrifugal fan is disposed in the second receiving cavity.

[0015] In one embodiment, the support body further includes a support frame, the outer shell is mounted on the support frame, and the centrifugal fan is fixedly connected to the side wall of the support frame;

[0016] The support frame includes at least two support rods, which are perpendicular to each other and fixedly connected.

[0017] This utility model also proposes a hanging air conditioner, including a hanging rod, an air outlet duct, two air inlet ducts, and a heat exchange device as described above. The first end of the hanging rod is installed on the ceiling, and the heat exchange device is installed on the second end of the hanging rod. The hanging rod and the support frame of the heat exchange device are arranged opposite to each other.

[0018] The two air inlets of the heat exchange device are connected to two air inlet pipes respectively, and the air outlet of the heat exchange device is connected to the air outlet pipe.

[0019] In one embodiment, the wall-mounted air conditioner further includes a flexible hose and a silencer.

[0020] The technical solution provided by this utility model has the following advantages and effects:

[0021] On the one hand, when the centrifugal fan starts, it draws air from two air inlets, which correspond to the first and second heat exchange ports respectively, thus accelerating the airflow through the first and second heat exchange ports. The first heat exchange mechanism exchanges heat with the air at the first heat exchange port, and the second heat exchange mechanism exchanges heat with the air at the second heat exchange port. The accelerated airflow through the first and second heat exchange ports can improve the heat exchange efficiency of the first and second heat exchange mechanisms.

[0022] On the other hand, since the two air inlets are arranged opposite each other, and each air inlet corresponds to the first heat exchange port and the second heat exchange port respectively, and the first heat exchange port and the second heat exchange port are also arranged opposite each other, the first heat exchange mechanism and the second heat exchange mechanism can be arranged symmetrically, making full use of the space inside the support body. The air outlet is located on the outer surface of the support body. When the first heat exchange mechanism and the second heat exchange mechanism are started, the first heat exchange mechanism exchanges heat with the air at the first heat exchange port, and the second heat exchange mechanism exchanges heat with the air at the second heat exchange port. The air outlet discharges the hot air from the first heat exchange port and the second heat exchange port. Attached Figure Description

[0033] To facilitate understanding of this utility model, the specific embodiments of this utility model will be described in more detail below with reference to the accompanying drawings.

[0034] Unless otherwise specified or defined, the terms "first," "second," etc., used in this document are for distinguishing names only and do not represent a specific number or order.

[0035] Unless otherwise stated or defined, the term “and / or” as used herein includes any and all combinations of one or more of the associated listed items.

[0036] It should be noted that when a component is considered "fixed" to another component, it can be directly fixed to the other component or there can be an intervening component; when a component is considered "connected" to another component, it can be directly connected to the other component or there can be an intervening component; when a component is considered "mounted" on another component, it can be directly mounted on the other component or there can be an intervening component; when a component is considered "placed" on another component, it can be directly placed on the other component or there can be an intervening component.

[0037] This utility model proposes a heat exchange device 100, such as Figures 1 to 4As shown, the system includes a support body 1, a first heat exchange mechanism 2, a second heat exchange mechanism 3, and a centrifugal fan 4. The first heat exchange mechanism 2, the second heat exchange mechanism 3, and the centrifugal fan 4 are all installed inside the support body 1. The support body 1 has a first heat exchange port 13 and a second heat exchange port 14 on both sides. The centrifugal fan 4 is located between the first heat exchange port 13 and the second heat exchange port 14. The first heat exchange mechanism 2 is at least partially located near the first heat exchange port 13, and the second heat exchange mechanism 3 is at least partially located near the second heat exchange port 14. The centrifugal fan 4 has an air outlet 42 and two air inlets 41. The air outlet 42 is located on the outer surface of the support body 1, and the two air inlets 41 are arranged opposite to each other. The two air inlets 41 correspond to the first heat exchange port 13 and the second heat exchange port 14, respectively.

[0038] Specifically, since the support body 1 has a first heat exchange port 13 and a second heat exchange port 14 on both sides, the centrifugal fan 4 is located between the first heat exchange port 13 and the second heat exchange port 14, while the first heat exchange mechanism 2 is located near the first heat exchange port 13 and the second heat exchange mechanism 3 is located near the second heat exchange port 14. When the centrifugal fan 4 is started, it draws air from the two air inlets 41, which correspond to the first heat exchange port 13 and the second heat exchange port 14 respectively, thus accelerating the air flow in the first heat exchange port 13 and the second heat exchange port 14. The first heat exchange mechanism 2 exchanges heat with the air at the first heat exchange port 13, and the second heat exchange mechanism 3 exchanges heat with the air at the second heat exchange port 14. The accelerated air flow in the first heat exchange port 13 and the second heat exchange mechanism 3 can improve the heat exchange efficiency of the first heat exchange mechanism 2 and the second heat exchange mechanism 3.

[0039] Furthermore, since the two air inlets 41 are arranged opposite each other, and the two air inlets 41 correspond to the first heat exchange port 13 and the second heat exchange port 14 respectively, and the first heat exchange port 13 and the second heat exchange port 14 are also arranged opposite each other, the first heat exchange mechanism 2 and the second heat exchange mechanism 3 can be arranged symmetrically, making full use of the space inside the support body 1. The air outlet 42 is located on the outer surface of the support body 1. When the first heat exchange mechanism 2 and the second heat exchange mechanism 3 are started, the first heat exchange mechanism 2 exchanges heat with the air at the first heat exchange port 13, and the second heat exchange mechanism 3 exchanges heat with the air at the second heat exchange port 14. The air outlet 42 discharges the hot air from the first heat exchange port 13 and the second heat exchange port 14.

[0040] In addition, even if the first heat exchange mechanism 2 or the second heat exchange mechanism 3 is installed close to the wall, the centrifugal fan 4 can draw air from the first heat exchange port 13 or the second heat exchange port 14 to reduce the air resistance when air enters the first heat exchange mechanism 2 and the second heat exchange mechanism 3, making the air extraction more uniform and ensuring the normal operation of the first heat exchange mechanism 2 and the second heat exchange mechanism 3.

[0041] Preferably, the first heat exchange mechanism 2 includes a first air-side heat exchanger 21, a first compressor 22, a first connecting pipe 23, a first condenser 24, and a first pipe 25. The first air-side heat exchanger 21 is installed at the first heat exchange port 13, and a first air duct 15 is formed between the first air-side heat exchanger 21 and one of the air inlets 41. The first condenser 24 has a first heat exchange chamber and a second heat exchange chamber (not shown in the figure). The first heat exchange chamber and the second heat exchange chamber are separated. The first air-side heat exchanger 21, the first compressor 22, and the first heat exchange chamber are connected by the first connecting pipe 23 to form a first temperature regulator. The second heat exchange chamber is connected to the first pipe 25.

[0042] Specifically, the first air-side heat exchanger 21, the first compressor 22, and the first heat exchange chamber are connected by a first connecting pipe 23, forming a first temperature regulator. The heat exchange medium flows within the first connecting pipe 23, enters the suction end of the first compressor 22, and discharges high-pressure, high-temperature heat exchange medium from the discharge end of the first compressor 22. The heat exchange medium enters the first condenser 24 for condensation and heat release, and then flows back to the first air-side heat exchanger 21 to exchange heat with the air at the first heat exchange outlet 13. The heat exchange medium completes evaporation and heat absorption in the first air-side heat exchanger 21, thereby lowering the indoor temperature and completing summer cooling. When heating in winter, the heat exchange medium flows in the reverse direction in the first connecting pipe 23. The heat exchange medium completes condensation and heat release in the first air-side heat exchanger 21, and evaporation and heat absorption in the first condenser 24. The first pipe 25 is used to transport cooling water, which exchanges heat with the heat exchange medium in the second heat exchange chamber and the first heat exchange chamber, further enabling the first temperature regulator to regulate the indoor temperature.

[0043] Preferably, the second heat exchange mechanism 3 includes a second air-side heat exchanger 31, a second compressor 32, a second connecting pipe 33, a second condenser 34, and a second pipe 35. The second air-side heat exchanger 31 is installed at the second heat exchange port 14, and a second air duct 16 is formed between the second air-side heat exchanger 31 and another air inlet 41. The second condenser 34 has a third heat exchange chamber and a fourth heat exchange chamber, which are separated from each other. The second air-side heat exchanger 31, the second compressor 32, and the third heat exchange chamber are connected by the second connecting pipe 33 to form a second temperature regulator. The fourth heat exchange chamber is connected to the second pipe 35.

[0044] Specifically, the second air-side heat exchanger 31, the second compressor 32, and the second heat exchange chamber are connected by a second connecting pipe 33 to form a second temperature regulator. The heat exchange working fluid flows in the second connecting pipe 33. The structure, technical principle, and technical effect of the second heat exchange mechanism 3 are similar to those of the first heat exchange mechanism 2, and will not be described in detail here.

[0045] Preferably, the first pipe 25 is an inlet pipe, and the second pipe 35 is an outlet pipe. Both inlet pipes are connected to the first end of the second and fourth heat exchange chambers, and both outlet pipes are connected to the second end of the second and fourth heat exchange chambers. Specifically, the water supply pipe 207 is connected to the first pipe 25, and the drainage pipe 208 is connected to the second pipe 35. Both the water supply pipe 207 and the drainage pipe 208 are equipped with valves 209. Cooling water enters the second and fourth heat exchange chambers through the first pipe 25, exchanges heat with the heat exchange medium in the first and third heat exchange chambers, and then flows out from the second pipe 35, thus achieving cooling water circulation.

[0046] Preferably, both the first and second temperature regulators are equipped with throttling valves. Specifically, the throttling valve blocks the flow of the heat exchange medium through a small orifice or narrow channel inside the valve, working in conjunction with the compressor to create a high-pressure zone (condenser end) and a low-pressure zone (evaporator end) in the system. This process reduces the pressure of the high-pressure liquid heat exchange medium output from the condenser to the evaporation pressure, while simultaneously lowering the temperature, allowing the heat exchange medium to rapidly vaporize and absorb heat in the evaporator, thus achieving a refrigeration cycle.

[0047] Preferably, the air inlet 41 is perpendicular to the air outlet 42. Specifically, the air inlet 41 is perpendicular to the air outlet 42. Air from both sides of the outer casing 12 enters the air inlet 41 through the first air duct 15 and the second air duct 16, and exits from the air outlet 42. The air inlet and outlet are relatively independent to avoid interference. Hot air is discharged after heat exchange, further improving heat exchange efficiency.

[0048] In other embodiments, the support body 1 includes an outer shell 12 and an inner shell 17. An installation cavity is formed within the outer shell 12, and the inner shell 17 is installed within the installation cavity, separating the installation cavity to form a first receiving cavity 101 and a second receiving cavity 102. A first heat exchange mechanism 2 and a second heat exchange mechanism 3 are disposed within the first receiving cavity 101, and a centrifugal fan 4 is disposed within the second receiving cavity 102. Specifically, this installation cavity is separated by the inner shell 17 to form the first receiving cavity 101 and the second receiving cavity 102. The pipelines of the first heat exchange mechanism 2 and the second heat exchange mechanism 3 are placed in the first receiving cavity 101, while the second receiving cavity 102 is used to house the centrifugal fan 4, and provides ample space for air from the first heat exchange port 13 to circulate between the first air duct 15 and the air inlet 41, and for air from the second heat exchange port 14 to circulate between the second air duct 16 and the air inlet 41.

[0049] Preferably, the support body 1 further includes a support frame 11, the outer shell 12 is mounted on the support frame 11, and the centrifugal fan 4 is fixedly connected to the side wall of the support frame 11; the support frame 11 includes at least two support rods, which are perpendicular to each other and fixedly connected. Specifically, the support frame 11 is used to support the outer shell 12 and improve the stability of the outer shell 12. At the same time, the support frame 11 is also used to improve the stability of the centrifugal fan 4 inside the outer shell 12; the two support rods are perpendicular to each other and form the support frame 11, which can play a certain supporting role.

[0050] like Figure 5 As shown, this utility model also proposes a hanging air conditioner 200, including a hanging rod 202, an air outlet duct 203, two air inlet ducts 204, and a heat exchange device 100 as described above. The first end of the hanging rod 202 is installed on the ceiling 201, and the heat exchange device 100 is installed on the second end of the hanging rod 202. The hanging rod 202 and the support frame 11 of the heat exchange device 100 are arranged opposite to each other. The two air inlets 41 of the heat exchange device 100 are respectively connected to the two air inlet ducts 204, and the air outlet 42 of the heat exchange device 100 is connected to the air outlet duct 203.

[0051] Specifically, the heat exchange device 100 is suspended from the ceiling 201 by a hanging rod 202. The air inlet duct 204 is used to transport indoor air to the centrifugal fan 4. The centrifugal fan 4 accelerates the air flow in the room and improves the indoor cooling efficiency. The first heat exchange mechanism 2 and the second heat exchange mechanism 3 exchange heat with the air at the first heat exchange port 13 and the second heat exchange port 14. After evaporation and heat absorption by the first air-side heat exchanger 21 and the second air-side heat exchanger 31, the air is cooled down and enters the air outlet 42 through the centrifugal fan 4 and is discharged from the air outlet duct 203 to achieve indoor cooling.

[0052] Furthermore, the hanging rod 202 is positioned opposite to the support frame 11 of the heat exchange device 100, so that the support frame 11 supports the first heat exchange mechanism 2, the second heat exchange mechanism 3, and the centrifugal fan 4, thereby improving the structural stability of the heat exchange device 100.

[0053] Preferably, the wall-mounted air conditioner 200 further includes a flexible hose 206 and a silencer 205. The air inlet duct 204 is connected to the air inlet 41 via the flexible hose 206, and the air outlet duct 203 is connected to the air outlet 42 via the flexible hose 206. The silencer 205 is fitted over the air inlet duct 204 or the air outlet duct 203. Specifically, the air inlet duct 204 and the air outlet duct 203 are connected to the air inlet 41 and the air outlet 42 respectively via the flexible hose 206, improving the installation flexibility of the air inlet duct 204 and the air outlet duct 203; at the same time, the silencer 205 is fitted over the air inlet duct 204 or the air outlet duct 203 to reduce the noise generated by the centrifugal fan 4 when drawing air.

[0054] When referencing drawings, new features are explained. To avoid redundant references to drawings that would make the description less concise, features already described will not be referenced again on the drawings if the description is clear.
