Thus, the appearances of "in one embodiment" or "in an embodiment" in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any manner in one or more embodiments.

[0039] like Figures 1 to 2 As shown, an embodiment of the present invention provides a heat exchange device, including a box body 1, and the heat exchange device also includes:

[0040] A fan assembly is arranged in the first area of ​​the box body 1;

[0041] A first heat exchange assembly, the first heat exchange assembly is disposed in the second area of ​​the housing 1 and below the fan assembly; and

[0042] The second heat exchange component is arranged in the third area inside the box body 1 and is located below the first heat exchange component. The first end of the second heat exchange component is connected to one end of the first heat exchange component, and the second end of the second heat exchange component is connected to the external water supply equipment; the refrigerant is compressed by the first heat exchange component to perform heat exchange treatment on the water to be heat exchanged entering the second heat exchange component.

[0043] In this embodiment, the fan assembly, the first heat exchange assembly, and the second heat exchange assembly are sequentially arranged from top to bottom inside the housing 1, respectively occupying different areas inside the housing 1, so as to improve the rationality of the layout of the components inside the housing 1 and avoid mutual interference between different components during the operation of the entire device. Among them, the fan assembly is arranged at the top of the housing 1, mainly used to assist the first heat exchange assembly in heat exchange and heat dissipation, and also assist in the internal heat dissipation of the entire heat exchange device.

[0044] The first heat exchange component is connected to the second heat exchange component so that the refrigerant in the first heat exchange component can be used to perform heat exchange and cooling treatment on the water to be exchanged in the second heat exchange component. At the same time, it is also convenient to recover the refrigerant to achieve the recycling of the refrigerant. Here, the refrigerant is in a gas-liquid mixed state before entering the second heat exchange component. After entering the second heat exchange component for heat exchange, it is evaporated into a gaseous state and recovered into the first heat exchange component through the pipeline connecting the second heat exchange component and the first heat exchange component to achieve recycling.

[0045] By arranging different components in different areas, different components can cooperate with each other to exchange heat, thereby improving the heat exchange efficiency. At the same time, the layout of different components in the heat exchange equipment box is made more reasonable, thereby reducing the production, preparation and maintenance costs of the heat exchange equipment.

[0046] In an optional embodiment of the present invention, the first heat exchange component includes:

[0047] A flat microchannel heat exchanger 2 is disposed below the fan assembly and fixedly connected to both sides of the housing 1, with the second end of the microchannel heat exchanger 2 communicating with the first end of the second heat exchange assembly; and

[0048] The compressor 3 is arranged below the microchannel heat exchanger 2, one side of the compressor 3 is connected to the first end of the microchannel heat exchanger 2, and the other side of the compressor 3 is connected to the first end of the second heat exchange component.

[0049] In this embodiment, the compressor 3 serves as a gaseous refrigerant supply device. One side of the compressor 3 is connected to the first end of the flat-plate microchannel heat exchanger 2 via a second pipe 30 to provide high-pressure gaseous refrigerant to the microchannel heat exchanger 2. The other side of the compressor 3 is connected to the second heat exchange component to recover the refrigerant. Here, the gaseous refrigerant may be Freon gas.

[0050] The flat-plate microchannel heat exchanger 2 acts as a condenser, condensing the high-pressure gaseous refrigerant provided by the compressor 3 and converting it into high-pressure liquid refrigerant for use by the second heat exchange component; the two ends of the flat-plate microchannel heat exchanger 2 are fixedly connected to the inner walls on both sides of the box body 1, and a refrigerant inlet and outlet are opened on the first end. The gaseous refrigerant enters through the refrigerant inlet, is condensed in the microchannel heat exchanger 2, and circulates once before flowing out through the refrigerant outlet. The outflowing high-pressure liquid refrigerant flows into the second heat exchange component through the first pipe 20 to assist the second heat exchange component in heat exchange; here, the flat-plate microchannel heat exchanger 2, on the one hand, occupies a smaller space in the box body 1, which can reduce the volume of the entire box design; on the other hand, compared with conventional heat exchangers, the microchannel heat exchanger can improve the heat exchange efficiency of the entire heat exchange equipment due to its higher heat exchange efficiency; in addition, unlike conventional heat exchangers, the preparation cost of the microchannel heat exchanger is also relatively low, which further reduces the manufacturing cost of the entire heat exchange equipment.

[0051] In an optional embodiment of the present invention, the compressor 3 is fixedly connected to the inner wall of the box body 1 through a shock-absorbing base;

[0052] In this embodiment, the compressor 3 is fixedly connected to the inner wall of the box body 1 through a shock-absorbing base to reduce the impact of vibration generated by the compressor 3 during operation on other components in the box body 1 and the entire heat exchange device;

[0053] Specifically, the shock-absorbing base includes:

[0054] A base 301, the base 301 is fixedly connected to the inner wall of the box 1; and

[0055] Multiple shock-absorbing pads 302 , the multiple shock-absorbing pads 302 are evenly distributed on the base 301 , and the upper end surfaces of the multiple shock-absorbing pads 302 are fixedly connected to the compressor 3 ;

[0056] Here, one side of the base 301 can be welded and fixed to the inner wall of the box body 1, and a plurality of shock-absorbing pads 302 are installed on the other side. The upper end surfaces of the plurality of shock-absorbing pads 302 are fixedly connected to the compressor 3 to reduce the impact of vibration generated by the compressor 3 during operation on the overall equipment; preferably, the plurality of shock-absorbing pads 302 can be made of flexible materials, such as rubber.

[0057] In an optional embodiment of the present invention, the second heat exchange component includes:

[0058] a plate heat exchanger 4, wherein a first position of a first end of the plate heat exchanger 4 is connected to a second end of the microchannel heat exchanger 2, a second position of the first end of the plate heat exchanger 4 is connected to one side of the compressor 3, and a third position of the second end of the plate heat exchanger 4 is connected to a water outlet at the bottom of the housing 1; and

[0059] A water pump 5, wherein the input end of the water pump 5 is connected to the water inlet at the bottom of the box body 1, and the output end of the water pump 5 is connected to the fourth position of the second end of the plate heat exchanger 4; wherein, the height from the first position to the inner wall of the box body 1 is less than the height from the second position to the inner wall of the box body 1, and the height from the third position to the inner wall of the box body 1 is less than the height from the fourth position to the inner wall of the box body 1.

[0060] In this embodiment, the plate heat exchanger 4 acts as an evaporator, and exchanges heat with the water in its pipeline by evaporating the gas-liquid mixed refrigerant entering it; a refrigerant inlet is opened at a first position of the first end of the plate heat exchanger 4, and a refrigerant outlet is opened at a second position; wherein the refrigerant inlet is connected to the second end of the microchannel heat exchanger 2, and the refrigerant outlet is connected to one side of the compressor 3. After the liquid refrigerant enters the plate heat exchanger 4 from the refrigerant inlet at a lower height, it is evaporated inside the plate heat exchanger 4 and converted into a gaseous refrigerant. After a cycle, it flows out of the plate heat exchanger 4 from the refrigerant outlet at a higher height and enters the compressor 3 for recycling;

[0061] A water outlet is provided at the third position of the second end of the plate heat exchanger 4, and a water inlet is provided at the fourth position; wherein the water inlet is connected to the output end of the water pump 5, and the water delivered by the external equipment is pumped into the pipeline of the plate heat exchanger 4 through the water pump 5, and the water outlet is connected to the water outlet at the bottom of the box body 1, so as to discharge the cooled water from the pipeline of the plate heat exchanger 4.

[0063] In this embodiment, the gaseous refrigerant is converted into a high-temperature and high-pressure gaseous refrigerant after being compressed by the compressor 3, and then enters the microchannel heat exchanger 2 for condensation and is converted into a normal-temperature and high-pressure liquid refrigerant. The normal-temperature and high-pressure liquid refrigerant flows to the plate heat exchanger 4 through the first pipe 20. When flowing through the electromagnetic expansion valve 21, the electromagnetic expansion valve throttles the normal-temperature and high-pressure liquid refrigerant to become low-temperature and low-pressure wet steam. The low-temperature and low-pressure wet steam then absorbs heat in the plate heat exchanger 4 to achieve a heat exchange effect.

[0064] Preferably, a dryer 12 is also provided on the first pipe 20, and the dryer 12 is provided on the first pipe 20 between the expansion valve 21 and the second end of the microchannel heat exchanger 2; before filling the refrigerant, residual moisture may remain in the first pipe 20 due to incomplete vacuuming or errors in the installation or welding process. After filling the refrigerant, the residual moisture may condense in the low-temperature pipe and cause ice blockage. The setting of the dryer 12 can absorb this moisture to avoid ice blockage.

[0065] In an optional embodiment of the present invention, the fan assembly includes:

[0066] A fan bracket 6 is disposed in the first area of ​​the box body 1 , and one side of the fan bracket 6 is fixedly connected to the inner wall of the box body 1 ; and

[0067] The fan 7 is arranged in the fan bracket 6 and is fixedly connected to the fan bracket 6.

[0069] In an optional embodiment of the present invention, a fan protection net 60 is provided on the top of the box body 1 to prevent the operator from accidentally touching the fan 7.

[0075] a second pressure sensor 41 provided on a third pipe 40 at a second position connecting the first end of the plate heat exchanger 4 and one side of the compressor 3;

[0076] A third pressure sensor 51 is provided on a fourth pipe 50 connecting the input end of the water pump 5 and the water inlet at the bottom of the box 1 .

[0079] In this embodiment, since the fourth pipe 50 and the fifth pipe 52 are both pipes for water circulation, both can be pipes made of flexible materials, such as rubber. On the one hand, the flexible pipe can relieve the pressure generated when the water flows, and on the other hand, it is easy to install; in addition, compared with pipes made of other metal materials, the flexible pipe also reduces the production and use costs of the heat exchange equipment; preferably, the fourth pipe 50 can be fixed to the inner wall of the bottom of the box body 1 by a clamp, and the fifth pipe 52 can be supported by a pipe bracket 52 to avoid pipe collapse and affect the flow of water.
