Description

Technical Field

[0001] This invention relates to the field of heat pump equipment technology, and in particular to a heat pump equipment with optimized and improved performance. Background Technology

[0002] An air source heat pump is an energy regeneration device that uses air heat energy for heating. It is frequently used in air conditioners and heating systems. For example, the hot water we use for bathing needs to rely on an air source heat pump so that the water temperature can rise in a very short time. Similarly, the heating mode of an air conditioner also relies on an air source heat pump.

[0003] However, most existing heat pump devices structurally include a mounting frame to support the entire unit. This frame typically houses a titanium tube heat exchanger, a refrigerant circulation system, a modular electrical box, a finned heat exchanger, and an exhaust fan. The titanium tube heat exchanger and the finned heat exchanger exchange heat through the refrigerant circulation pipes of the refrigerant circulation system. Driven by a compressor within the refrigerant circulation system, the refrigerant circulates between the finned and titanium tube heat exchangers. The exhaust fan draws outside air into the heat pump through airflow channels within the mounting frame. As the outside air travels along these channels past the finned heat exchangers, the refrigerant exchanges heat with the air, absorbing low-grade heat. This heat is then transferred through the refrigerant circulation pipes to the interior of the titanium tube heat exchanger and further to the circulating water pipes inside. The water in these pipes continuously collects heat from the outside air, thus enabling the heat pump to collect heat from the ambient air.

[0004] However, the aforementioned existing heat pump equipment still exhibits poor heat exchange performance, generally due to the following three reasons:

[0005] 1. Due to the limited opening area of ​​the air inlet in the existing air source heat pump, the amount of external air drawn in is restricted. This results in insufficient intake of external heat source air by the heat pump equipment, which in turn prevents the finned heat exchanger inside the heat pump from exchanging heat with enough external heat source air, leading to poor heat exchange performance of the heat pump equipment.

[0006] 2. In most heat pump equipment, the internal titanium tube heat exchanger assembly structure typically has multiple heat exchangers connected in series to the inlet and outlet pipes. Water entering from the inlet pipe flows through each heat exchanger in sequence before exiting from the outlet pipe. This results in a large water flow rate for the titanium tube heat exchangers near the outlet of the inlet pipe, while the water flow rate for those farther away is small. This leads to a certain difference in the water flow rate of each titanium tube heat exchanger, resulting in uneven water flow throughout the entire titanium tube heat exchanger assembly. Consequently, the overall heat exchange effect of the titanium tube heat exchanger assembly is poor, which indirectly weakens the actual heat exchange capacity of the heat pump equipment.

[0007] 3. Existing finned heat exchanger structures are generally composed of three or more rows of copper tube aluminum fin assemblies. Each row of copper tube aluminum fin assemblies extends from the bottom to the top of the heat pump and is arranged side by side. That is, the structure of the finned heat exchanger is composed of multiple layers of copper tube aluminum fin assemblies arranged side by side. During operation, the refrigerant circulates in each layer of copper tube aluminum fin assemblies and exchanges heat with the air entering the heat pump equipment. However, in practical applications, the airflow generated by the fan exhibits a phenomenon where the airflow increases closer to the fan and decreases further away. This results in a larger airflow near the fan and a smaller airflow further away from the fan within the heat pump. This leads to uneven airflow across the upper, middle, and lower sections of the heat pump, with the lowest airflow at the bottom, followed by the middle, and the highest at the top. Consequently, the top of the finned heat exchanger has a high heat exchange demand, while the bottom has a low demand. The upper part of the finned heat exchanger receives the most heat exchange due to its greater contact with the airflow, while the airflow gradually weakens further away from the fan. The middle and bottom of the finned heat exchanger have relatively less contact with the airflow, resulting in a reduced degree of heat exchange. Existing finned heat exchangers, with their structure consisting of three or more layers of copper tube and aluminum fin assemblies arranged side-by-side from bottom to top within the heat pump, and each layer having the same specifications and dimensions, suffer from reduced heat exchange efficiency in the middle and lower parts of the finned heat exchanger, failing to fully utilize its heat exchange performance. The heat exchange effect in the middle and lower parts of the finned heat exchanger is poor. Summary of the Invention

[0008] In order to solve the technical problems existing in the prior art to a certain extent, the present invention provides a heat pump device with optimized and improved performance. The structure of the heat pump device is optimized and improved from multiple aspects, thereby further improving the heat exchange performance of the heat pump device.

[0009] This invention discloses a heat pump device with optimized performance, comprising a mounting frame. The mounting frame contains a titanium tube heat exchanger assembly, a refrigerant circulation system, a modular electrical box, and an airflow channel. A finned heat exchanger is mounted on the airflow channel. The titanium tube heat exchanger assembly and the finned heat exchanger exchange heat through the refrigerant circulation pipe of the refrigerant circulation system. An exhaust fan connected to the airflow channel is installed at the top air outlet of the mounting frame.

[0010] The mounting frame is surrounded by multiple grid plates, and multiple grid holes distributed on the grid plates respectively penetrate into the interior of the mounting frame to connect the airflow channel;

[0011] The titanium tube heat exchanger assembly includes an inlet pipe, an outlet pipe, and multiple heat exchangers. The inlet of each heat exchanger is connected to the inlet pipe, and the outlet of each heat exchanger is connected to the outlet pipe.

[0012] The finned heat exchanger includes several overlapping heat exchange combination layers, each of which extends along the exhaust direction of the exhaust fan; the starting ends of each heat exchange combination layer overlap each other near the exhaust fan, and the ending ends of each heat exchange combination layer are staggered from each other away from the exhaust fan.

[0014] According to a performance-optimized heat pump device of the present invention, the titanium tube heat exchanger assembly further includes a first water distributor and a second water distributor; the inlet of the first water distributor is connected to the inlet pipe; multiple water outlets of the first water distributor are respectively connected to a first multi-port pipe through pipes; multiple water outlets of each of the first multi-port pipes are respectively connected to the inlet of each of the heat exchangers.

[0015] The outlet of the second water distributor is connected to the outlet pipe; the multiple outlets of the second water distributor are respectively connected to the second multi-port pipe through pipes; the multiple inlets of each of the second multi-port pipes are respectively connected to the outlets of each of the heat exchangers.

[0016] According to a heat pump device with performance optimization and improvement according to the present invention, each heat exchange combination layer includes a plurality of finned heat exchange tubes, and each finned heat exchange tube is arranged along the exhaust direction of the exhaust fan. The finned heat exchange tubes of heat exchange combination layers with different extension lengths have different arrangement lengths.

[0017] A heat exchange assembly with shorter finned heat exchange tube arrangement lengths is closer to the airflow generated by the exhaust fan than a heat exchange assembly with longer finned heat exchange tube arrangement lengths.

[0018] According to a performance-optimized heat pump device of the present invention, the module electrical box is provided with an air inlet chamber and an air outlet chamber. The air inlet chamber is used to connect to the first air inlet of the heat pump, and the electrical components are located in the air inlet chamber. The air outlet chamber is used to connect to the exhaust fan. A partition plate is provided between the air inlet chamber and the air outlet chamber, and a ventilation structure connecting the air inlet chamber and the air outlet chamber is provided on the partition plate.

[0019] According to a heat pump device with performance optimization and improvement according to the present invention, the ventilation structure includes a hollow shell, a first through hole on one side of the hollow shell corresponding to the air inlet cavity, and a second through hole on one side of the hollow shell corresponding to the air outlet cavity.

[0020] According to a heat pump device with optimized and improved performance according to the present invention, the mounting frame is provided with a fan mounting plate and a fan support plate;

[0021] The fan mounting plate has fan mounting holes for fixing the exhaust fan.

[0022] The fan support plate and the fan mounting plate overlap each other in a cross shape and support the fan mounting plate upwards at the position of the fan mounting hole.

[0023] According to a heat pump device with optimized performance according to the present invention, an electrical box support frame for sleeved onto the module electrical box is fixedly provided inside the mounting frame;

[0024] The fan mounting plate has a first bent plate integrally formed at each of its opposite ends, and a first hook is provided on the first bent plate; the fan support plate has a second bent plate integrally formed at each of its opposite ends, and a second hook is provided on the second bent plate.

[0025] One end of the fan mounting plate is fixedly hung on the mounting frame by the first hook, and the other end is fixedly hung on the electrical box support frame by the first hook;

[0026] The two opposite ends of the fan support plate are respectively fixedly hung on the mounting frame by the second hook.

[0027] According to a heat pump device with optimized performance according to the present invention, the fan mounting plate and the fan support plate are respectively integrally formed with fixing pieces, and the fixing pieces of the fan mounting plate and the fixing pieces of the fan support plate are overlapped in correspondence.

[0028] According to a heat pump device with performance optimization and improvement according to the present invention, the mounting frame further includes an outer frame and an inner frame, both of which are located at the top of the mounting frame and are spaced apart from each other by a certain distance, and a slot is formed by the distance between the outer frame and the inner frame.

[0029] The first hook at the end of the fan mounting plate is engaged in the slot.

[0030] The second hooks at both ends of the fan support plate are engaged in the slots.

[0031] The present invention provides a performance-optimized and improved heat pump device by improving the structure of the heat pump in the following three aspects:

[0032] 1. First, multiple grid plates are arranged around the outer perimeter of the mounting frame, with grid holes extending into the interior of the mounting frame to connect the airflow channels. These grid holes also connect to the air outlet at the top of the mounting frame. Therefore, when the exhaust fan at the top of the mounting frame starts and draws air from the internal airflow channels, the air pressure inside the mounting frame decreases. External hot air then automatically enters the interior of the mounting frame through the grid holes. Since the grid holes surround the perimeter of the mounting frame, external hot air can simultaneously enter the interior of the mounting frame from various sides of its perimeter. The airflow channels allow external heat source air to enter the heat pump equipment more fully, enabling the finned heat exchanger inside the heat pump equipment to come into more complete contact with the external air. The refrigerant circulation pipe can also exchange heat more fully with the external air, allowing the refrigerant inside the refrigerant circulation pipe to absorb heat from the external air more fully. Driven by the refrigerant circulation system, the refrigerant that has fully absorbed heat through the finned heat exchanger continues to flow into the titanium tube heat exchanger assembly through the refrigerant circulation pipe and comes into heat transfer contact with the water pipe inside it. The water flow in the water pipe inside the titanium tube heat exchanger assembly can then obtain heat more fully, ultimately effectively improving the heat exchange effect of the heat pump equipment.

[0033] 2. Because the inlets of each heat exchanger inside the titanium tube heat exchanger assembly are connected to the inlet pipe and the outlets of each heat exchanger are connected to the outlet pipe, not only can the external water flow enter each heat exchanger more synchronously and in parallel, but the water flow inside each heat exchanger can also flow out more synchronously and in parallel. This structural improvement to the water pipe network inside the titanium tube heat exchanger assembly effectively replaces the traditional sequential flow of water through each heat exchanger, resulting in a more uniform water flow within the assembly. This optimizes the heat exchange effect of the titanium tube heat exchanger assembly and ultimately helps improve the heat exchange capacity of the heat pump equipment.

[0034] 3. Since each heat exchange combination layer of the finned heat exchanger extends along the exhaust direction of the exhaust fan, and the starting ends of each heat exchange combination layer overlap each other near the exhaust fan while the ending ends of each heat exchange combination layer are staggered away from the exhaust fan, the finned heat exchanger can have a larger number of heat exchange combination layers near the exhaust fan, fully matching the characteristics of the largest air volume and the largest heat exchange demand at this location. At the same time, since the ending ends of each heat exchange combination layer are staggered away from the exhaust fan, the finned heat exchanger can form a stepped structure as it gradually moves away from the exhaust fan. The number of overlapping heat exchange combination layers in the finned heat exchanger can be adjusted along the exhaust direction of the exhaust fan to match the strength and variation of the exhaust fan's airflow, optimizing the overall heat exchange effect of the finned heat exchanger and further improving the heat exchange performance of the heat pump equipment.

[0063] like Figures 1 to 14As shown, this embodiment of a performance-optimized heat pump device includes a mounting frame 100. Inside the mounting frame 100 are installed a titanium tube heat exchanger assembly 200, a refrigerant circulation system 300, a modular electrical box 500, and a finned heat exchanger 400. An airflow channel (not shown in the figure) is also formed within the mounting frame 100. This airflow channel passes through the finned heat exchanger 400 within the mounting frame 100. The titanium tube heat exchanger assembly 200 and the finned heat exchanger 400 exchange heat through the refrigerant circulation pipe 301 of the refrigerant circulation system 300. Specifically, the refrigerant circulation pipe 301 passes through the finned heat exchanger 400 and the titanium tube heat exchanger assembly 200, allowing the refrigerant to circulate between them. Furthermore, an exhaust fan 102 connected to the airflow channel is installed at the top air outlet 101 of the mounting frame 100. To optimize the heat exchange performance of the heat pump equipment, this embodiment makes optimizations and improvements to the mounting frame 100, the titanium tube heat exchanger assembly 200, and the finned heat exchanger 400. Specifically, the mounting frame 100 is surrounded by multiple grid plates 600, and multiple grid holes 601 on the grid plates 600 extend into the interior of the mounting frame 100 to connect airflow channels; the titanium tube heat exchanger assembly 200 includes an inlet pipe 201, an outlet pipe 202, and multiple heat exchangers 203, each of which... The water inlet of each heat exchanger 203 is connected to the water inlet pipe 201, and the water outlet of each heat exchanger 203 is connected to the water outlet pipe 202. The finned heat exchanger 400 includes multiple heat exchange combination layers 401 that are stacked together. Each heat exchange combination layer 401 extends along the exhaust direction of the exhaust fan 102. The starting ends of the extension of each heat exchange combination layer 401 are stacked together near the exhaust fan 102, and the ending ends of the extension of each heat exchange combination layer 401 are staggered away from the exhaust fan 102.

[0064] It is understood that the present invention first involves multiple grid plates 600 circumferentially surrounding the outer side of the mounting frame 100, allowing multiple grid holes 601 arranged on the grid plates 600 to penetrate into the interior of the mounting frame 100 to connect the airflow channels. The grid holes 601 on the perimeter also connect to the air outlet 101 at the top of the mounting frame 100. Therefore, when the exhaust fan 102 at the air outlet 101 at the top of the mounting frame 100 starts and draws air from the internal airflow channels of the mounting frame 100, the air pressure in the internal airflow channels of the mounting frame 100 decreases. External hot air will then automatically enter the interior of the mounting frame 100 through the grid holes 601 arranged on the grid plates 600. Since the grid holes 601 circumferentially surround the mounting frame 100 along with the grid plates 600, external hot air can simultaneously enter the interior of the mounting frame 100 from the grid plates 600. The airflow channels on all sides of the mounting bracket 100 allow external heat source air to enter the heat pump equipment more fully, enabling the finned heat exchanger 400 inside the heat pump equipment to have more complete contact with the external air. The refrigerant circulation pipe 301 can also exchange heat more fully with the external air, allowing the refrigerant inside the refrigerant circulation pipe 301 to absorb heat from the external air more fully. Driven by the refrigerant circulation system 300, the refrigerant that has fully absorbed heat by flowing through the finned heat exchanger 400 continues to flow into the titanium tube heat exchanger assembly 200 through the refrigerant circulation pipe 301 and comes into heat transfer contact with the water pipes inside. The water flow in the water pipes inside the titanium tube heat exchanger assembly 200 can then obtain heat more fully, ultimately effectively improving the heat exchange effect of the heat pump equipment. Secondly, because the inlets of each heat exchanger 203 inside the titanium tube heat exchanger assembly 200 are connected to the inlet pipe 201 and the outlets of each heat exchanger 203 are connected to the outlet pipe 202, this not only allows external water to enter each heat exchanger 203 more synchronously and in parallel, but also allows the water inside each heat exchanger 203 to flow out more synchronously and in parallel. This structural improvement to the water pipes inside the titanium tube heat exchanger assembly 200 effectively replaces the traditional sequential flow of water through each heat exchanger, resulting in a more uniform water flow within the assembly. This optimizes the heat exchange effect of the titanium tube heat exchanger assembly and ultimately helps improve the heat exchange capacity of the heat pump equipment.Furthermore, since each heat exchange assembly layer 401 of the finned heat exchanger 400 extends along the exhaust direction of the exhaust fan 102, and the starting ends of each heat exchange assembly layer 401 overlap near the exhaust fan 102 while the ending ends are staggered away from the exhaust fan 102, the finned heat exchanger 400 can have a larger number of heat exchange assembly layers 401 arranged near the exhaust fan 102, fully matching the maximum airflow and heat exchange requirements at this location. The most significant feature is that, since the extended ends of each heat exchange combination layer 1 are staggered at positions away from the exhaust fan 102, the finned heat exchanger can form a stepped structure as it moves away from the exhaust fan 102. The number of stacked layers of the heat exchange combination layer 401 within the finned heat exchanger 400 can be adjusted along the exhaust direction of the exhaust fan 102 to match the strength variation of the exhaust fan's airflow, thereby optimizing the overall heat exchange effect of the finned heat exchanger 400 and further improving the heat exchange performance of the heat pump equipment.

[0065] In one embodiment, the refrigerant circulation system 300 further includes a compressor 302, a four-way valve 303, a liquid receiver 304, a separator 305, and an electronic expansion valve 306. The compressor 302, four-way valve 303, liquid receiver 304, separator 305, and electronic expansion valve 306 are arranged around the outside of the titanium tube heat exchanger assembly 200, thus allowing for a more compact internal structure of the heat pump device. The refrigerant circulation system 300 is a commonly used component in heat pumps, and the connection relationships of its components will not be elaborated here; however, in this embodiment, the components of the refrigerant circulation system 300 are arranged around the outside of the titanium tube heat exchanger assembly 200 to achieve a more compact internal structure, which is a specific design feature.

[0066] In one embodiment, a water receiving tray (not shown in the figure) is distributed around the bottom edge of the mounting bracket 100. The water receiving tray has several through holes 103. A water receiving tray (not shown in the figure) is located below the water receiving tray, and a water outlet communicating with the outside is provided on the water receiving tray. The finned heat exchanger is positioned directly opposite the bottom through holes 103, meaning that the orthographic projection of the finned heat exchanger completely covers the orthographic projection of the bottom through holes 103 when viewed from above. Alternatively, the orthographic projection of the finned heat exchanger can partially cover the orthographic projection of the bottom through holes 103 when viewed from above. Several support feet 104 are installed at the bottom of the mounting bracket 100. Each support foot 104 raises the mounting bracket 100 from the bottom, thus reserving installation space for the water receiving tray by increasing the height of the mounting bracket 100. In a preferred embodiment, the water receiving tray has a certain gap from the ground, which helps to improve the service life of the water receiving tray. In actual use, finned heat exchangers may experience frost formation. The design of the bottom through holes 103 and water collection troughs allows the water from the defrosting process to flow from the bottom through holes 103 into the water collection troughs and then out of the heat pump, thus protecting the heat pump and improving the heat exchange efficiency of the finned heat exchanger. The distance between the water collection trough pad and the water collection trough is 10-15mm, which facilitates drainage.

[0067] In one embodiment, the titanium tube heat exchanger assembly 200 further includes a first water distributor 204 and a second water distributor 205. On one hand, when constructing the inlet pipe structure of the titanium tube heat exchanger assembly 200, the inlet of the first water distributor 204 is connected to the inlet pipe 201. In this embodiment, the first water distributor 204 has two water outlets, each connected to a first multi-way pipe 206 via a pipe. Optionally, in this embodiment, the first multi-way pipe 206 is a tee pipe, and the two outlets of each first multi-way pipe 206 are connected to the inlet of a heat exchanger 203. That is, the outlet of each first multi-way pipe 206 is connected to the inlet of a heat exchanger 203. On the other hand, when constructing the outlet pipe structure of the titanium tube heat exchanger assembly 200, the outlet of the second water distributor 205 is connected to the outlet pipe 202. Optionally, the second water distributor 205 in this embodiment has two water outlets, and the two water outlets of the second water distributor 205 are respectively connected to a second multi-way pipe 207. That is, the two water outlets of the second water distributor 205 are respectively connected to a second multi-way pipe 207. Optionally, the second multi-way pipe 207 in this embodiment is a three-way pipe. The two inlet ends of the second multi-way pipe 207 are respectively connected to the outlet of a heat exchanger 203. That is, the inlet end of each second multi-way pipe 207 is respectively connected to the outlet of a heat exchanger 203.

[0068] It is understood that the titanium tube heat exchanger assembly 200 in this embodiment is equipped with a first water distributor 204 and a second water distributor 205. In the water inlet pipe structure of the titanium tube heat exchanger assembly 200, the inlet of the first water distributor 204 is connected to the inlet pipe 201, and the multiple outlets of the first water distributor 204 are respectively connected to a first multi-port pipe 206. Finally, the multiple outlets of each first multi-port pipe 206 are respectively connected to the inlet of each heat exchanger 203. Therefore, when external water flows into the inlet pipe 201, it can be simultaneously diverted to multiple first multi-port pipes 206 through the various outlets of the first water distributor 204, and then continue to be synchronously diverted through the first multi-port pipes 206 and enter each heat exchanger 203 in the titanium tube heat exchanger assembly. The water flow structure allows water to enter each heat exchanger 203 synchronously and in parallel. On the other hand, in the outlet pipe structure of the titanium tube heat exchanger assembly, the outlet of the second water distributor 205 is connected to the outlet pipe 202, and the multiple outlets of the second water distributor 205 are connected to a second multi-port pipe 207. Finally, the multiple inlets of each second multi-port pipe 207 are connected to the outlets of each heat exchanger 203. Therefore, when the water inside each heat exchanger 203 flows out, it will first flow to each second multi-port pipe 207, and then continue to flow to the second water distributor 205 through the second multi-port pipe 207, and finally converge to the outlet pipe 202 and flow outward. This outlet pipe structure allows the water inside each heat exchanger 203 to flow outward synchronously and in parallel. The above structure effectively replaces the traditional method of allowing water to flow sequentially through each heat exchanger 203 in a series manner. To a certain extent, it can make the water flow rate in the titanium tube heat exchanger assembly more uniform, thereby optimizing the heat exchange effect of the titanium tube heat exchanger assembly and thus helping to improve the heat exchange capacity of the heat pump equipment.

[0069] Specifically, it also includes a mounting base 208, which is used to fix it inside the mounting bracket 100. Specifically, a seventh bent plate 209 is integrally formed on each of the opposite sides of the mounting base 208. Multiple screw holes 210 are provided on the seventh bent plate 209, allowing the mounting base 208 to be fixedly installed inside the heat pump equipment through the connection and cooperation of screws with the screw holes 210. Furthermore, multiple connecting plates 211 are integrally formed on the bottom outer wall of each heat exchanger 203. These connecting plates 211 are distributed around the outer wall of the heat exchanger 203 and are fixedly connected to the mounting base 208. A second reinforcing rib 212 is integrally formed at the corner where each connecting plate 211 meets the outer wall of the heat exchanger 203. Optionally, each connecting plate 211 has an integrally formed opening groove 213 that penetrates through the connecting plate 211. Correspondingly, the mounting base 208 has multiple screw holes (not shown in the figure), each screw hole corresponding to the opening groove 213 of each connecting plate 211. When connecting the mounting base 208 and the heat exchanger 203, the threaded part of the screw passes through the opening groove 213 of the connecting plate 211 and is threaded into the screw hole of the mounting base 208, while the screw head is fixedly engaged with the top of the opening groove 213. This structure facilitates the installation of the heat exchanger 203. During installation, it is only necessary to ensure that the screw hole at the top of the mounting base 208 falls into the opening groove 213, which simplifies positioning and reduces the installation difficulty of the heat exchanger 203.

[0070] Specifically, a first temperature sensor 214 is installed on the inlet pipe 201 or the first distributor 204. Optionally, in this embodiment, the first temperature sensor 214 is installed on the first distributor 204 to monitor the inlet water temperature of the titanium tube heat exchanger assembly. Similarly, a second temperature sensor 215 is installed on the outlet pipe 202 or the second distributor 205. Optionally, in this embodiment, the second temperature sensor 215 is installed on the second distributor 205 to monitor the outlet water temperature of the titanium tube heat exchanger assembly. The addition of the first temperature sensor 214 and the second temperature sensor 215 facilitates the heat pump control system to monitor the inlet and outlet water temperatures of the titanium tube heat exchanger assembly in real time, thereby enabling the control system to make timely temperature control adjustments.

[0071] Specifically, the inlet of the first distributor 204 is fixedly fitted with a first flange 216, and the inlet pipe 201 is fixedly fitted with a second flange 217. The first flange 216 and the second flange 217 are fixedly connected to each other at the joint between the inlet pipe 201 and the first distributor 204, thereby making the joint between the inlet pipe 201 and the first distributor 204 more secure. Similarly, the outlet of the second distributor 205 is fixedly fitted with a third flange 218, and the outlet pipe 202 is fixedly fitted with a fourth flange 219. The third flange 218 and the fourth flange 219 are fixedly connected to each other at the joint between the outlet pipe 202 and the second distributor 205, thereby making the joint between the outlet pipe 202 and the second distributor 205 more secure.

[0072] Specifically, the first flange 216 and the second flange 217 are stacked on top of each other, and multiple bolts 220 are arranged circumferentially and threaded together to connect the first flange 216 and the second flange 217, ensuring a secure connection between them. Similarly, the third flange 218 and the fourth flange 219 are stacked on top of each other, and multiple bolts 220 are arranged circumferentially and threaded together to connect the third flange 218 and the fourth flange 219, ensuring a secure connection between them. To enhance sealing, sealing rings are provided between the first flange 216 and the second flange 217, and between the third flange 218 and the fourth flange 219.

[0073] Specifically, in order to improve structural strength, a plurality of circumferentially arranged first reinforcing ribs 221 are fixedly provided at the corner between the first water distributor 204 and the first flange 216. Similarly, a plurality of circumferentially arranged first reinforcing ribs 221 are also fixedly provided at the corner between the water inlet pipe 201 and the second flange 217, a plurality of circumferentially arranged first reinforcing ribs 221 are also fixedly provided at the corner between the second water distributor 205 and the third flange 218, and a plurality of circumferentially arranged first reinforcing ribs 221 are also fixedly provided at the corner between the water outlet pipe 202 and the fourth flange 219.

[0074] Specifically, each heat exchanger 203 is internally equipped with refrigerant heat exchange tubes (not shown in the figure). These refrigerant heat exchange tubes and the water pipes inside the heat exchanger 203 are in heat transfer contact to achieve heat exchange. In addition, the heat exchanger 203 is externally equipped with a refrigerant inlet pipe 222 and a refrigerant outlet pipe 223. The refrigerant inlet pipe 222 is connected to the inlet end of the refrigerant heat exchange tube, and the refrigerant outlet pipe 223 is connected to the outlet end of the refrigerant heat exchange tube. The refrigerant inlet pipe 222 and the refrigerant outlet pipe 223 are respectively connected to the refrigerant circulation pipe 301 of the refrigerant circulation system 300. Therefore, the refrigerant in the refrigerant circulation pipe 301 can enter the refrigerant heat exchange tube inside the heat exchanger 203 through the refrigerant inlet pipe 222, and can be output outward through the refrigerant outlet pipe 223 to flow back to the refrigerant circulation pipe, so that the refrigerant in the refrigerant circulation pipe can circulate into the heat exchanger 203.

[0075] Specifically, preferably, the diameter of the refrigerant inlet pipe 222 is larger than the diameter of the refrigerant outlet pipe 223. This allows the instantaneous inflow of refrigerant into the heat exchanger 203 to be greater than the instantaneous outflow, thus reducing the refrigerant's flow velocity within the heat exchanger 203 and ensuring more efficient heat exchange. Furthermore, each heat exchanger 203's outlet is equipped with a flow switch connector 224 for connecting and installing a flow switch. Therefore, the flow rate of water at each heat exchanger 203's outlet can be controlled by the flow switch. The flow switch connector 224 has an integrally formed external threaded pipe 225 for threaded connection to the flow switch, making the installation of the flow switch easier and more convenient.

[0076] In one embodiment, the finned heat exchanger 400 of this embodiment is provided with three heat exchange combination layers 401. The three heat exchange combination layers 401 respectively include a plurality of finned heat exchange tubes 402. The finned heat exchange tubes 402 are used to connect to the refrigerant circulation pipe 301 in the mounting bracket 100. Under the driving action of the refrigerant circulation system 300, the refrigerant in the refrigerant circulation pipe 301 can be driven to circulate into the interior of the heat exchange combination layer 401 and exchange heat. The refrigerant can then exchange heat with the outside air through the heat exchange combination layer 401, absorb the heat from the outside heat source air, and continue to send the heat to the titanium tube heat exchanger assembly 200 through the refrigerant circulation pipe 301. The circulating water inside the titanium tube heat exchanger assembly 200 can then absorb the heat from the refrigerant. Furthermore, in this embodiment, the finned heat exchange tubes 402 are arranged along the exhaust direction of the exhaust fan 102. The finned heat exchange tubes 402 of the heat exchange combination layers 401 with different extension lengths have different arrangement lengths. The heat exchange combination layer 401 with a shorter arrangement length of finned heat exchange tubes 402 is closer to the airflow generated by the exhaust fan 102 than the heat exchange combination layer 401 with a longer arrangement length of finned heat exchange tubes 402. That is, in this embodiment, the ends of the finned heat exchange tubes 402 of the three heat exchange combination layers 401 are at different height positions.

[0077] It is understandable that the above structure allows the finned heat exchanger to have a greater number of finned heat exchange tubes 402 near the exhaust fan 102, fully matching the characteristics of the largest airflow and the greatest heat exchange demand at this location. Simultaneously, because the ends of the finned heat exchange tubes 402 in the three heat exchange combination layers 401 are arranged at different heights, the extension lengths of the three heat exchange combination layers 401 in the exhaust direction of the exhaust fan 102 are different, and the lower ends of the three heat exchange combination layers 401 are staggered to match the variation in airflow strength of the fan, optimizing the overall heat exchange effect of the finned heat exchanger and the heat pump equipment. This structure also ensures that the airflow generated by the exhaust fan 102 can contact each heat exchange combination layer 401, achieving contact and heat exchange, ensuring that the finned heat exchanger can fully exchange heat with the airflow generated by the exhaust fan 102.

[0078] Specifically, an end plate 403 is installed at the end of the finned heat exchanger. Several end plate through holes 404 are distributed on the surface of the end plate 403. Each finned heat exchange tube 402 is inserted into each end plate through hole 404. Thus, each finned heat exchange tube 402 can be supported by each end plate through hole 404 on the end plate 403, ensuring the stable installation of each finned heat exchange tube 402.

[0079] Specifically, there are two end plates 403, which are installed at both ends of the finned heat exchanger, thereby supporting each finned heat exchange tube 402 from both ends and improving structural stability.

[0080] Specifically, the heat exchange assembly layer 401 also includes several U-shaped tubes 405. The two ends of each U-shaped tube 405 are respectively connected to the openings of two adjacent finned heat exchange tubes 402, thus facilitating the interconnection of each finned heat exchange tube 402, and allowing the refrigerant to flow smoothly into each finned heat exchange tube 402 through each U-shaped tube 405.

[0081] Specifically, each heat exchange assembly layer 401 includes several straight sections 406, and a bend section 407 is connected between every two straight sections 406. Therefore, the extension direction of each straight section 406 can be changed through the bend section 407, which is conducive to assembling heat exchange assembly layers 401 with different contour shapes, and helps to match finned heat exchangers with heat pumps of different shapes.

[0082] Specifically, the heat exchange assembly layer 401 is an L-shaped layer so that the finned heat exchanger can be adapted to a heat pump with a square profile. Alternatively, the heat exchange assembly layer 401 can be set as a C-shaped layer or a U-shaped layer according to the profile shape of the heat pump so that the finned heat exchanger can be adapted to be installed in heat pump equipment with different profile shapes.

[0083] In one embodiment, a partition plate 503 is fixedly installed inside the modular electrical box 500. The partition plate 503 is used to install and fix electrical components 507. In addition, the modular electrical box 500 also has an air inlet cavity 501 and an air outlet cavity 502. The air inlet cavity 501 is located at the top of the modular electrical box 500 and is used to connect to the first air inlet 105 of the heat pump to allow outside air to enter. The electrical components are located in the air inlet cavity 501. The air outlet cavity 502 is located at the bottom of the modular electrical box 500 and is connected to the exhaust fan 102 through an airflow channel. The air inlet cavity 501 and the air outlet cavity 502 are separated by the partition plate 503. At the same time, the partition plate 503 is also provided with a ventilation structure connecting the air inlet cavity 501 and the air outlet cavity 502.

[0084] It is understood that in the modular electrical box structure of this embodiment, the partition plate 503 originally used for installing electrical components is used to divide the interior of the modular electrical box 500 into an air inlet cavity 501 and an air outlet cavity 502. A ventilation structure is added to the partition plate 503 to make the air inlet cavity 501 and the air outlet cavity 502 interconnected. During assembly, the electrical component 507 is located in the air inlet cavity 501, and the air inlet cavity 501 is connected to the first air inlet 105, while the air outlet cavity 502 is connected to the exhaust fan 102 of the heat pump equipment. With the above structure, when the heat pump is running, the exhaust fan 102 starts rotating, drawing in hot air from the internal airflow channel of the heat pump. Under the action of air pressure difference, external air automatically enters the heat pump from the first air inlet 105. External air also continuously flows into the air inlet cavity 501 of the module electrical box 500. Since the module electrical box 500 is divided into air inlet cavities 501, external air first concentrates and enters the air inlet cavity 501. After entering the air inlet cavity 501, the external air can then contact the electrical components 507 and absorb the heat generated by the electrical components 507. The heat exchanged between the air in the air inlet cavity 501 and the electrical components 507 allows the air to continuously enter the air outlet cavity 502 through the ventilation structure. With the continuous suction of the exhaust fan 102, the air in the air outlet cavity 502 is eventually drawn out of the heat pump equipment. This cycle allows the airflow to circulate into the interior of the module electrical box 500, making the interior of the module electrical box 500 more smoothly ventilated and achieving the purpose of optimizing the ventilation effect of the module electrical box. This allows the airflow to flow more smoothly inside the module electrical box, ultimately effectively improving the heat dissipation performance of the module electrical box.

[0085] Specifically, the first air inlets 105 are distributed on opposite sides of the mounting bracket 100, and each first air inlet 105 is connected to the air inlet cavity 501 of the module electrical box 500 to ensure that external air can enter the interior of the air inlet cavity 501 through the first air inlet 105.

[0086] Specifically, the side wall of the modular electrical box 500 is provided with an air inlet 508. Optionally, in this embodiment, there are two air inlets 508, which are respectively located on opposite side walls of the modular electrical box 500. The two air inlets 508 are respectively connected to the air inlet cavity 501. When the modular electrical box 500 is installed inside the mounting bracket 100, the air inlets 508 on both sides are respectively used to connect to the first air inlet 105 of the mounting bracket 100. With the above structure, air from outside the heat pump equipment can smoothly enter the air inlet cavity 501 inside the modular electrical box 500 from each air inlet 508.

[0087] Specifically, the bottom of the modular electrical box 500 is equipped with a duct shell 509, that is, the duct shell 509 corresponds to one side of the air outlet cavity 502. The air outlet cavity 502 is formed between the partition plate 503 and the duct shell 509. In this way, the air outlet cavity 502 can be separated by the space between the duct shell 509 and the back of the partition plate 503.

[0088] Specifically, the partition plate 503 has a number of mounting holes 510, and an electrical component mounting plate 511 is fixedly fitted into each mounting hole 510. One side of the top of the electrical component mounting plate 511 is located in the air inlet cavity 501 and is used to install electrical components 507, while one side of the bottom of the electrical component mounting plate 511 is located in the air outlet cavity 502.

[0089] It is understandable that multiple electrical component mounting plates 511 are distributed on the partition plate 503, which facilitates the grouping and installation of electrical components 507. At the same time, the two sides of the electrical component mounting plates 511 are located in the air inlet cavity 501 and the air outlet cavity 502, respectively. Therefore, when the heat generated by the electrical component 507 is transferred to the electrical component mounting plates 511, since the two sides of the electrical component mounting plates 511 can contact the airflow in the air outlet cavity 502 and the air inlet cavity 501, the electrical component 507 can increase the contact area with the airflow through the electrical component mounting plates 511, and the heat exchange is more complete. This improves the heat dissipation effect of the electrical component 507.

[0090] Specifically, gaps 512 are provided between the various electrical component mounting plates 511, which can ensure smoother airflow within the modular electrical box 500 and increase the contact area between the airflow and the various electrical component mounting plates 511, thereby further improving the heat dissipation effect of the modular electrical box 500.

[0091] Specifically, the modular electrical box 500 has a frame side plate 513 on its periphery, and a gap 512 is also reserved between the inner side of the frame side plate 513 and the outer periphery of the electrical component mounting plate 511. Therefore, the gap can also be used to ensure smoother airflow within the modular electrical box 500, and to ensure that each electrical component mounting plate 511 has a larger contact area with the airflow, thereby improving the heat dissipation effect of the modular electrical box 500.

[0092] Specifically, the ventilation structure of this embodiment includes a hollow shell 504, on which a first through hole 505 and a second through hole 506 are provided. The first through hole 505 corresponds to one side of the air inlet cavity 501, and the second through hole 506 corresponds to one side of the air outlet cavity 502. Therefore, external air entering the air inlet cavity 501 can enter the interior of the hollow shell 504 through the first through hole 505 and smoothly enter the air outlet cavity 502 through the second through hole 506.

[0093] Specifically, the hollow shell 504 is elongated, extending along the length of the modular electrical box 500 and approaching multiple electrical components 507 within the modular electrical box 500. Furthermore, there are multiple first through holes 505 and second through holes 506, arranged along the extending direction of the hollow shell 504. With this structure, the airflow in the air inlet cavity 501 can enter the hollow shell 504 more quickly and efficiently through the first through holes 505, and then reach the air outlet cavity 502 within the modular electrical box 500 from multiple outlet positions through the second through holes 506, accelerating airflow within the modular electrical box 500 and thus achieving more thorough heat dissipation.

[0094] Specifically, multiple electrical component mounting plates 511 inside the module electrical box 500 are symmetrically distributed on opposite sides of the elongated hollow shell 504. After exchanging heat with the electrical components 507 in the air inlet cavity 501, the air can be output more quickly through the first through hole 505, thereby accelerating the airflow and further optimizing the heat dissipation effect.

[0095] Specifically, the ventilation structure includes at least one air guide hole 514. In this embodiment, there are multiple air guide holes 514, and the air guide holes 514 penetrate through the partition plate 503. Therefore, the airflow in the air inlet cavity 501 can also directly enter the air outlet cavity 502 through each air guide hole 514, making the airflow in the module electrical box 500 smoother.

[0096] Combination Figures 15 to 18 and combination Figures 1 to 3 As shown, a fan mounting plate 800 and a fan support plate 801 are installed inside the mounting bracket 100. The fan mounting plate 800 has a fan mounting hole 802, which is used to fix the exhaust fan 102. The fan support plate 801 overlaps the fan mounting plate 800 in a cross shape and supports the fan mounting plate 800 upward at the position of the fan mounting hole 802.

[0097] It is understandable that by fixing a fan mounting plate 800 inside the mounting bracket 100, when assembling the exhaust fan 102, the outer casing of the exhaust fan 102 can be directly fitted into the fan mounting hole 802 of the fan mounting plate 800, facilitating the installation and fixation of the exhaust fan 102. Furthermore, the fan mounting plate 800 also provides support for the exhaust fan 102. Additionally, since a fan support plate 801 is also additionally fixed inside the mounting bracket 100, and the fan support plate 801 supports the fan mounting plate 800 upwards, this further enhances the... The fan support plate 801 and the fan mounting plate 800 overlap in a cross shape and support the fan mounting plate 800 upwards at the fan mounting hole 802. Therefore, the cross-shaped overlapping structure further enhances the rigidity of the support frame formed by the combination of the fan support plate 801 and the fan mounting plate 800, which can more stably support the fan 102 upwards and prevent the fan mounting plate 800 from bending and falling due to the excessive weight of the fan 102, thus effectively enhancing the installation stability of the fan 102.

[0098] Specifically, on the one hand, an electrical box support frame 803 for supporting the module electrical box 500 is fixedly installed inside the mounting frame 100. On the other hand, first bent plates 804 are integrally formed on opposite ends of the fan mounting plate 800, and first hooks 805 are integrally formed on the first bent plates 804 by bending. Similarly, second bent plates 806 are integrally formed on opposite ends of the fan support plate 801, and second hooks 807 are also integrally formed on the second bent plates 806 by bending. During assembly, the opposite ends of the fan support plate 801 are fixedly hooked to the mounting frame 100 by the second hooks 807 to achieve stable assembly of the fan support plate 801 within the mounting frame 100. One end of the fan mounting plate 800 is fixedly hung on the mounting frame 100 by the first hook 805, and the other end is fixedly hung on the electrical box support frame 803 by the first hook 805. This not only enables the fan mounting plate 800 to be stably assembled in the mounting frame 100, but also allows the electrical box support frame 803 to be more stably assembled in the mounting frame 100 through the fan mounting plate 800.

[0099] Specifically, the electrical box support frame 803 is machined with a snap-fit ​​hole 808. The first hook 805 at one end of the fan mounting plate 800 engages with the snap-fit ​​hole 808 to facilitate the snap-fit ​​assembly of the fan mounting plate 800 and the electrical box support frame 803. The snap-fit ​​hole 808 is a strip-shaped structure, which can increase the area of ​​the snap-fit ​​assembly between the fan mounting plate 800 and the electrical box support frame 803 and improve the stability of the connection between the two.

[0100] Specifically, the first hooks 805 at opposite ends of the fan mounting plate 800 have different structures. Specifically, the first hook 805 at one end of the fan mounting plate 800 has a longer outward extension, while the first hook 805 at the other end of the fan mounting plate 800 has a shorter outward extension. When assembling the fan mounting plate 800, the longer first hook 805 is fixedly hooked to the mounting bracket 100, while the shorter first hook 805 is engaged with the snap-fit ​​hole 808 of the electrical box support bracket 803. This structure can reserve more space for the installation of the electrical box support bracket 803 and reduce the assembly difficulty.

[0101] Specifically, the fan mounting plate 800 and the fan support plate 801 are each integrally formed with fixing pieces 809. During assembly, each fixing piece 809 can be regarded as a positioning reference, so that the fixing pieces 809 of the fan mounting plate 800 and the fixing pieces 809 of the fan support plate 801 correspond to each other and overlap, thereby facilitating the accurate positioning and installation of the fan mounting plate 800 and the fan support plate 801. Finally, the two overlapping fixing pieces 809 can be completely fixedly connected by screws.

[0102] Specifically, the mounting bracket 100 also includes an outer frame 106 and an inner frame 107. Both the outer frame 106 and the inner frame 107 are located at the top of the mounting bracket 100 and are spaced a certain distance apart. A slot 108 is formed by the distance between the outer frame 106 and the inner frame 107. During assembly, the first hook 805 at one end of the fan mounting plate 800 engages with the slot 108, ensuring the fan mounting plate 800 is stably fastened to the mounting bracket 100. Similarly, the second hooks 807 at both ends of the fan support plate 801 also engage with the slots 108, ensuring the fan support plate 801 is stably fastened to the mounting bracket 100. After the first hook 805 and the second hook 807 are engaged with the slots 108, they can be fixed by using screws.

[0103] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
