Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to a valve island assembly and an air conditioner. Background Technology

[0002] Currently, air conditioner outdoor units on the market have a partition that divides the unit into a compressor chamber and a fan chamber. The compressor chamber houses the compressor and piping system, while the fan chamber houses the motor, fan blades, and heat exchanger. Specifically, the piping system integrates components such as a four-way valve, electronic expansion valve, plate heat exchanger, gas-liquid separator, oil separator, single-way solenoid valve, valve plate, high-pressure valve, low-pressure valve, and refrigerant heat sink. These components are connected by pipes. The refrigerant heat sink works by introducing refrigerant through copper pipes into the electronically controlled heating area, where the refrigerant flow continuously carries away heat from the electronic controls, thus cooling them. However, because these components are currently connected by pipes, the refrigerant flow path is relatively long, resulting in significant system pressure loss. This leads to a relatively slow refrigerant flow rate within the refrigerant heat sink's connecting pipes, limiting the heat dissipation effect of the heat sink. Utility Model Content

To this end, this invention provides a valve island assembly that can reduce pressure loss during refrigerant flow, increase the refrigerant flow velocity in the heat exchange channel, thereby improving the heat exchange efficiency between the heat exchange components and the electronic control board, and enhancing the operational safety of the air conditioner.

[0021] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0022] The following is for reference. Figures 2-5The valve island assembly 10 according to a first aspect embodiment of the present invention is described.

[0023] like Figures 2-4 As shown, the valve island assembly 10 according to the first aspect of this utility model is used in an air conditioner 1000. The air conditioner 1000 includes an electrical control box, which includes an electrical control board. Specifically, the air conditioner 1000 includes an outdoor unit 100 and an indoor unit 200. The electrical control box is generally located in the outdoor unit and is used to control the operation of some components inside the outdoor unit 100, such as the compressor 30 and the fan.

[0024] Specifically, the valve island assembly 10 includes: a valve island body 1 and a heat exchanger 2. The valve island body 1 has multiple channels formed inside, which are used to transmit refrigerant. The valve island body 1 has multiple interfaces, each of which is connected to one of the channels. The multiple interfaces include: a first interface 11 and a second interface 12. There are multiple first interfaces 11, which are configured to connect multiple control valves 20. The heat exchanger 2 is configured to exchange heat with the electronic control board. The heat exchanger 2 has a heat exchange flow channel, one end of which is connected to the second interface 12.

[0025] The phrase "multiple channels are formed inside the valve island body 1, and these channels are used to transmit refrigerant" can be understood as meaning that these channels formed inside the valve island can replace conventional pipelines for refrigerant transmission.

[0026] The valve island body 1 has multiple interfaces, each connected to one of the channels. These interfaces include a first interface 11 and a second interface 12. There are multiple first interfaces 11 configured to connect to multiple control valves 20. This indicates that multiple channels can be connected to multiple control valves 20 via the first interfaces 11. Each control valve 20 also has its own internal flow channel; that is, the two ends of the flow channel are connected to different channels via the first interfaces 11. In other words, multiple control valves 20 can be interconnected through the internal channels of the valve island body 1 to form a complete system flow path, in which refrigerant can flow. Therefore, it can be understood that the valve island body 1 can replace multiple connecting pipes in the existing air conditioner 1000 for refrigerant transmission. This reduces the space occupied by the piping system within the air conditioner 1000, improves the integration of the piping system and valves, and thus enhances the overall integration of the air conditioner 1000.

[0027] It should be noted that "heat exchanger 2 is configured for heat exchange with the electronic control board." Heat exchanger 2 uses the refrigerant flowing in the refrigeration circuit to dissipate heat from the electronic control board. The heat released by the electronic control board can be directly absorbed by heat exchanger 2, and the circulating refrigerant can quickly remove the heat, thus meeting the requirement of rapid heat dissipation of the electronic control board.

[0028] The statement "Heat exchanger 2 has a heat exchange channel, one end of which is connected to the second interface 12" indicates that heat exchanger 2 is connected to the channel inside the valve island body only at one end via the second interface 12, while the other end can be connected to an external pipeline. This means that when heat exchanger 2 is working, the refrigerant in the heat exchange channel can flow in through the channel inside the valve island body and then flow out through the external pipeline; alternatively, the refrigerant after heat exchange in the heat exchange channel can flow in through the external pipeline and then flow out through the channel inside the valve island body. The length of the channel inside the valve island is significantly shorter than that of the conventional piping, thereby reducing pressure loss during refrigerant flow and increasing the refrigerant velocity within the heat exchange channel. This, in turn, improves the heat exchange efficiency between heat exchanger 2 and the electronic control board.

[0029] According to the valve island assembly 10 of this utility model embodiment, by providing multiple channels and a first interface 11 and a second interface 12 connected to the channels in the valve island assembly 10, the integration of the piping system and control valve 20 of the air conditioner 1000 can be improved. At the same time, the refrigerant flow path can be shortened, thereby reducing the pressure loss during refrigerant flow and increasing the flow velocity of the refrigerant in the heat exchange channel. This can improve the heat exchange efficiency between the heat exchange component 2 and the electronic control board, and improve the operational safety of the air conditioner 1000.

[0030] According to some embodiments of this utility model, the multiple channels include: two first channels 131, and two second interfaces 12, each corresponding to and connected to one of the two first channels 131. The two ends of the heat exchange channel are connected to the two second interfaces 12 respectively. It can be understood that the refrigerant in the heat exchanger 2 flows in from the flow channel inside the valve island body 1 and flows out through the same flow channel. This further shortens the length of the external piping, reduces the pressure loss of the refrigerant in the flow channel, and further increases the refrigerant flow rate, thereby improving the heat exchange efficiency between the heat exchanger 2 and the electronic control board.

[0031] According to some embodiments of this utility model, such as Figures 3-4 As shown, the valve island assembly 10 also includes a first connecting pipe 3, and a second interface 12 is connected to the heat exchanger 2 through the first connecting pipe 3. This allows the length of the first connecting pipe 3 to be selected according to the position of the heat exchanger 2, thus facilitating the layout of the heat exchanger 2.

[0032] According to some embodiments of the present invention, at least a portion of the first connecting pipe 3 is configured to be elastically deformable. Specifically, the elastically deformable portion can act as a buffer zone, effectively absorbing and dispersing the transmitted vibration energy. Thus, by configuring at least a portion of the first connecting pipe 3 to be elastically deformable, the first connecting pipe 3 itself can dissipate a portion of the vibration energy, thereby reducing the impact of vibration on the heat exchanger 2 and improving the safety of the heat exchanger 2 in use.

[0033] The phrase "at least a portion of the first connecting pipe 3 is configured to be elastically deformable" can be understood to mean that the first connecting pipe 3 can be partially or entirely configured to be elastically deformable. It should be noted that configuring at least a portion of the first connecting pipe 3 to be elastically deformable can mean that at least a portion of the first connecting pipe 3 is supported by an elastically deformable material, or that at least a portion of the first connecting pipe 3 adopts a structural form with elastic deformation characteristics, such as a corrugated structure, a bend 34, or other flexible structural design; no limitation is made here.

[0034] According to some embodiments of this utility model, such as Figures 3-4 As shown, the first connecting pipe 3 has at least one bent portion 34. It can be understood that the first connecting pipe 3 may have one bent portion 34 or multiple bent portions 34. The bent portion 34 can extend the flow path, thereby reducing the amount of vibration transmitted to the heat exchanger 2 when the valve island vibrates, thus improving the safety of the heat exchanger 2 in use.

[0035] Optionally, there are two first connecting tubes 3, and at least one of the two first connecting tubes 3 has at least one bent portion 34. It is understood that the bent portion 34 can be formed on one of the first connecting tubes 3, or the bent portion 34 can be formed on both of them, which can further reduce the transmission of vibration.

[0036] According to some embodiments of this utility model, such as Figures 3-4 As shown, the first connecting pipe 3 includes: a first pipe section 31, a second pipe section 32, and a third pipe section 33. The first end of the first pipe section 31 is connected to the second interface 12. The second pipe section 32 is arranged at an angle to the first pipe section 31, and the first end of the second pipe section 32 is connected to the second end of the first pipe section 31 through a bend 34. The third pipe section 33 is arranged at an angle to the second pipe section 32, and the second end of the second pipe section 32 is connected to the first end of the third pipe section 33 through a bend 34. The second end of the third pipe section 33 is adapted to be connected to one end of the heat exchanger 2. Specifically, referring to the figure, the first pipe section 31 and the third pipe section 33 are arranged parallel and spaced apart. One end of the second pipe section 32 is connected to the first pipe section 31 through a bend 34, and the other end extends obliquely toward the third pipe section 33 and is connected to the third pipe section 33 through a bend 34. In this way, not only is the spatial arrangement flexibility of the pipeline improved, but the connection compatibility with the heat exchanger 2 is also enhanced. At the same time, it also helps to disperse stress and reduce the impact of vibration, thereby improving the overall stability and service life of the system.

[0037] Optionally, the first connecting pipe 3 can be formed by bending, that is, the first connecting pipe 3 can be formed as a single piece. This can reduce the number of welding points, thereby reducing leakage points and improving the safety of the air conditioner 1000.

[0038] Optionally, the first connecting pipe 3, the heat exchanger 2, and the second interface 12 can be welded, plugged, or other connection methods. The specific design depends on the actual situation and is not limited here.

[0039] According to some embodiments of this utility model, such as Figures 3-4 As shown, the bend 34 is bent into an arc-shaped pipe section. This arc-shaped section facilitates smooth refrigerant flow, reduces resistance, and increases refrigerant velocity, further enhancing the refrigerant velocity within the heat exchanger 2. This, in turn, improves the heat exchange effect of the heat exchanger 2 on the electronic control board. Simultaneously, the arc-shaped transition allows for a more even distribution of stress along the pipe section, reducing localized stress concentration. This, in turn, improves the structural strength and durability of the entire first connecting pipe 3, reducing the risk of fatigue damage caused by stress concentration.

[0040] According to some embodiments of this utility model, at least a portion of the plurality of first interfaces 11 and the opening direction of the second interface 12 are arranged parallel to one side surface of the valve island body 1. It is understood that the opening of at least a portion of the plurality of first interfaces 11 and the second interface 12 on the side wall of the valve block, with the opening direction parallel to one side surface of the valve island body 1, allows for easier docking of the plurality of valves and heat exchange components 2 with the valve island body 1 during assembly, eliminating the need for complex angle adjustments or spatial flipping, thereby simplifying the installation process and improving installation efficiency. Simultaneously, it allows installers to more intuitively see the interface positions during operation, reducing installation difficulties caused by limited viewing angles or narrow spaces. It also makes it easier to ensure correct alignment and fastening between the valves and the first interfaces 11, and between the heat exchange components 2 and the second interfaces 12, making the installation process more convenient and improving the reliability and safety of the air conditioner 1000.

[0041] An air conditioner 1000 according to a second aspect of the present invention includes a valve island assembly 10, a plurality of control valves 20, and an electrical control box according to a first aspect of the present invention. The control valves 20 are connected to a first interface 11. The electrical control box includes an electrical control board, and a heat exchanger 2 exchanges heat with the electrical control board.

[0042] Specifically, the valve island assembly 10 includes a valve island body 1, which has multiple channels for circulating refrigerant. These channels are not interconnected. The valve island body 1 has multiple first interfaces 11, and each channel is connected to one or two first interfaces 11. The control valve 20 also has a flow channel inside, and the two ends of the flow channel are connected to two different flow channels through the first interfaces 11 respectively. It can be understood that multiple control valves 20 and heat exchanger 2 are arranged on the valve island body 1 and interconnected through internal channels to form a complete system flow path, in which refrigerant can circulate.

[0043] The electrical control box includes an electrical control board, which is mainly used to control the operation of some components in the outdoor unit 100 of the air conditioner, such as the compressor 30 and the fan. It should be noted that the electrical control board generates a certain temperature during operation, which will cause it to heat up. Therefore, by using the heat exchanger 2 to exchange heat with the electrical control board, the electrical control board can operate within a safe temperature range, thereby improving the safety and service life of the electrical control board.

[0044] It should be noted that the heat exchanger 2 can extend into the electrical control box and be arranged on the side or bottom of the electrical control board, or it can be arranged on the outside of the electrical control box. The specific location is not limited.

[0045] According to the embodiment of the present utility model, by providing the valve island assembly 10 of the first aspect embodiment, the overall performance of the air conditioner 1000 can be effectively improved.

[0046] According to some embodiments of this utility model, the heat exchanger 2 is arranged at the bottom or side of the electrical control box. It is understood that the heat exchanger 2 is arranged on the outside of the electrical control box. This way, when the heat exchanger 2 is damaged and causes refrigerant leakage, direct contact between the refrigerant and the electrical control board inside the electrical control box can be effectively avoided, thereby further improving the operational safety of the electrical control board.

[0047] It should be noted that heat exchanger 2 can be a heat exchange plate or a U-shaped heat exchange tube. The specific form can be designed according to the actual situation, and there are no restrictions here.

[0048] According to some embodiments of this utility model, the plurality of control valves 20 includes one or more of the following: an electronic expansion valve 202, a four-way valve 203, a single-way solenoid valve 201, a high-pressure valve 204, and a low-pressure valve 205. It is understood that the plurality of control valves 20 may include any one of the above-mentioned valves, or may include multiple or all of the above-mentioned valves. In the prior art, the valves are connected to each other via pipelines, which results in difficult and time-consuming assembly. However, in the above embodiments, by connecting one or more valves to the valve island body 1 through multiple first interfaces 11, and since the first interfaces 11 can be arranged in an orderly manner on the valve island body 1 based on channels, the plurality of control valves 20 can be assembled in an orderly manner, thus reducing the assembly difficulty of the plurality of control valves 20. Simultaneously, connecting the plurality of control valves 20 to the valve island body 1 allows for pre-assembly and facilitates leak detection. Therefore, it can also save assembly welding time, reduce the number of weld points, and reduce the probability of leakage at the assembly weld points.

[0049] It should be noted that each of the above-mentioned valves may include one or more, and there is no restriction here. The specific selection and design should be based on the actual situation.

[0050] According to some specific embodiments of this utility model, for example Figure 1 and 5 As shown, the air conditioner 1000 includes an indoor unit 200 and an outdoor unit 100. The outdoor unit 100 further includes a compressor 30, an outdoor heat exchanger 50, a plate heat exchanger 60, and a gas-liquid separator 70. The compressor 30 is used to compress the refrigerant; the outdoor heat exchanger 50 is used to exchange heat with the outdoor environment; the plate heat exchanger 60 is used to replenish gas and increase enthalpy for the compressor 30 in heating mode. The plate heat exchanger 60 is arranged on one side of the valve island body 10 and is connected to multiple channels inside the valve island body 10 through multiple third interfaces; the gas-liquid separator 70 is used for gas-liquid separation, allowing gas to enter the return pipe of the compressor 30 and preventing liquid from impacting the compressor 30.

[0051] Optionally, the plate heat exchanger 60 can be positioned parallel to or perpendicular to one surface of the valve island body 1 along its length. During assembly, the plate heat exchanger 60 can be positioned parallel or perpendicular to one surface of the valve island body 1 along its length (i.e., the length direction of the plate heat exchanger 60). These different configurations allow the valve island assembly 10 to flexibly adjust the plate heat exchanger 60 according to varying installation space and layout requirements. Whether in a compact installation environment with limited space or a specific layout requiring optimized fluid flow, optimal fit can be achieved by adjusting the installation direction of the plate heat exchanger 60. Installers can choose the most suitable installation direction based on actual conditions without requiring complex modifications or adjustments to the valve island assembly 10. Furthermore, during maintenance, the plate heat exchanger 60 can be more easily accessed and inspected, improving the convenience and efficiency of maintenance. The plate heat exchanger 60 can be installed in different directions, providing more options and possibilities for the assembly of the valve island assembly 10, enabling the valve island assembly 10 to adapt to air conditioning systems in different application scenarios, thereby meeting different needs and offering high flexibility.

[0052] Furthermore, by adjusting the installation direction of the plate heat exchanger 60, the flow path and velocity of the refrigerant within the heat exchanger can be affected, thereby optimizing heat exchange efficiency. In some cases, installation parallel to the surface of the valve island body 1 may be more conducive to uniform refrigerant distribution and efficient heat exchange; while in other cases, vertical installation may be more helpful in reducing fluid resistance and improving the overall system performance.

[0053] In some embodiments, the plate heat exchanger 60 is arranged parallel to some surfaces of the valve island body 1 in the length direction, that is, the plate heat exchanger 60 is placed horizontally; the plate heat exchanger 60 is arranged perpendicular to some surfaces of the valve island body 1 in the length direction, that is, the plate heat exchanger 60 is placed vertically.

[0054] According to one embodiment of the present invention, the plate heat exchanger 60 is provided with four plate heat exchanger 60 interfaces on the side facing the valve island body 1, and the four plate heat exchanger 60 interfaces are arranged in a rectangular shape; the valve block is provided with four first valve island interfaces, the four first valve island interfaces are arranged in a corresponding rectangular shape and are respectively connected to the corresponding plate heat exchanger 60 interfaces.

[0055] The four plate heat exchanger interfaces 60 on the plate heat exchanger 60 are arranged in a rectangular pattern, and the four first valve island interfaces on the valve block are also arranged in a corresponding rectangular pattern. This standardized interface layout design makes the connection between the two more efficient and accurate. The rectangular arrangement helps ensure that each interface can be precisely aligned with the corresponding valve island interface, reducing connection problems caused by interface misalignment and improving the reliability and stability of the system. Because the interface layout of the plate heat exchanger 60 is standardized and corresponds one-to-one with the first valve island interfaces, installers can complete the operation more quickly and accurately when connecting the plate heat exchanger 60 and the valve block, reducing the error rate during installation, reducing commissioning time, and improving overall installation efficiency.

[0056] In some embodiments, of the four plate heat exchanger interfaces 60 on the plate heat exchanger 60, two may be interconnected and the other two may also be interconnected, that is, two refrigerant flow paths may be formed within the plate heat exchanger 60, and the refrigerant in the two refrigerant flow paths may exchange heat within the plate heat exchanger 60.

[0057] In some embodiments, more flow channels may be formed within the plate heat exchanger 60.

[0058] The multiple control valves 20 include: electronic expansion valve 202a, electronic expansion valve 202b, single-way solenoid valve 201, four-way valve 203, low-pressure valve 205 and high-pressure valve 204.

[0059] Specifically, electronic expansion valve 202a has a first inlet and a second inlet; electronic expansion valve 202b has a third inlet and a fourth inlet; single-way solenoid valve 201 has a fifth inlet and a sixth inlet; four-way valve 203 has a seventh inlet, an eighth inlet, a ninth inlet, and a tenth inlet; low-pressure valve 205 has an eleventh inlet and a twelfth inlet; and high-pressure valve 204 has a thirteenth inlet and a fourteenth inlet.

Refrigerant flow path during heating operation: (1) After the compressor 30 discharges, it enters the oil separator 40 through the first pipe, then enters the third channel 133 through the fifth interface, then flows out through the first interface 11d, and enters the four-way valve 203 through the eighth inlet and outlet, then flows out through the ninth inlet and outlet into the fourth channel 134, and flows into the low-pressure valve 205 through the eleventh inlet and outlet through the fourth channel 134, and finally enters the indoor heat exchanger through the twelfth inlet and outlet.

[0064] (2) After the indoor heat exchanger exchanges heat with the environment, the refrigerant enters through the thirteenth inlet and outlet of the high-pressure valve 204 and flows into the fifth channel 135, and then into the plate heat exchanger 60 through the fifth channel 135. It then splits into two paths: one path flows through the third interface a into the first channel 131b, and then into the heat exchanger 2 through the first channel 131b to achieve heat exchange with the electronic control board. The refrigerant after heat exchange enters the other first channel 131a, and then enters the electronic expansion valve 202 through the second inlet and outlet. It enters the outdoor heat exchanger 50 through one of the second channels 132a; after the outdoor heat exchanger 50 exchanges heat with the outdoor environment, it enters the four-way valve 203 through another second channel 132b and the seventh inlet and outlet, then flows out through the tenth inlet and outlet, and enters the sixth channel 136 through the first interface 11i, and then enters the gas-liquid separation device for gas-liquid separation, and then enters the seventh channel 137 through the sixth interface b, and then flows out through the seventh interface and enters the return pipe of the compressor 30; Another path flows into the first channel 131b through the third interface a, and into the single-way solenoid valve 201 through the eighth channel 138. Then it flows out through the sixth inlet and outlet, and into the ninth channel 139 through the first interface 11k. A capillary structure is formed in the ninth channel 139 for primary throttling. Then it enters the electronic expansion valve 202b through the first interface 11m for secondary throttling, and then flows into the plate heat exchanger 60 through the tenth channel 14. After the refrigerant has fully exchanged heat with the main line in the branch of the plate heat exchanger 60, it enters the enthalpy-increasing port of the compressor 30 through the second piping.

[0065] II. Refrigerant flow path during refrigeration operation: After the compressor 30 discharges, it enters the oil separator 40 through the first pipe, then enters the third channel 133 through the fifth interface, then flows out through the first interface 11d, and enters the four-way valve 203 through the eighth inlet and outlet. After flowing out through the seventh inlet and outlet, it enters the second channel 132b through the first interface 11c, then flows into the electronic expansion valve 202a through the second channel 132a, and then flows out through the second inlet and outlet to the first channel 131a. It then enters the heat exchanger 2 through the second interface 12. After the heat exchange is completed, the refrigerant enters the plate heat exchanger 60 through the first channel 131b, then enters the high-pressure valve 204 through the fifth channel 135, and then enters the indoor heat exchanger through the fourteenth inlet and outlet. After the indoor heat exchanger finishes heat exchange, the refrigerant enters the four-way valve 203 through the low-pressure valve 205, and then returns to the compressor 30.
