Detailed Description
The combined air conditioner unit is one kind of air treating equipment assembled with various air treating functional sections and may filter, purify, dehumidify, heat or cool air. For example, the combined air conditioning unit may use chilled water or vaporized endothermic refrigerant as a cold source to cool or dehumidify the air flowing therethrough. The combined air conditioning unit may also use hot water, hot air, steam or liquid exothermic refrigerant or the like as a heat source to heat the air flowing therethrough.
The combined air conditioning units are classified according to structural types and can be divided into horizontal type, vertical type and suspended ceiling type. The combined air conditioning units can be classified into a general unit, a fresh air unit, a purification unit and a special unit according to the application characteristics. The air purifying system is used for various clean plants or indoor spaces. Such as subways, exhibition centers, airports, malls, hotels, restaurants, office buildings, movie theaters, stadiums, precision machinery factories and the like, can be used for controlling and regulating the internal air environment.
As shown in fig. 1, an embodiment of the present application provides a combined air conditioning unit 100, and the combined air conditioning unit 100 may include a cabinet 10, a fan assembly 20, and a filter 30. Illustratively, the housing 10 may have a receiving chamber 11 formed therein, the housing 10 may have a return air inlet 12 and an air outlet 13 formed in a sidewall thereof, and the return air inlet 12 and the air outlet 13 may communicate with the receiving chamber 11. The fan assembly 20 may be installed in the box 10 (i.e. in the accommodating cavity 11), so that the fan assembly 20 may drive air to flow from the air return opening 12 to the air supply opening 13 in the accommodating cavity 11. Based on this, the filter 30 may be installed in the accommodating chamber 11 with the filter 30 located between the return air port 12 and the air supply port 13 in the flow direction of the air, so that the filter 30 may filter the air flowing into the air supply port 13 to achieve the purification of the air.
When the combined air conditioning unit 100 is applied, as shown in fig. 2, the conducting duct structure 300 may be connected to the air outlet side of the indoor space 200, and the conducting duct structure 300 may be connected to the air outlet side of the indoor space 200 as well. Based on this, one of the air duct structures 300 may be communicated with the return air inlet 12 shown in fig. 1, and the other air duct structure 300 may be communicated with the supply air inlet 13. So that air can circulate among the indoor space 200, the duct structure 300, the combination air conditioner unit 100, another duct structure 300, and the indoor space 200. In this way, the circulating air can be filtered through the filter 30 of the combined air conditioner 100, thereby purifying the air in the indoor space 200.
In addition, part or all of the dirty air may be discharged during the flow of air in the indoor space 200 into the combined air conditioning unit 100. Correspondingly, the combined air conditioning unit 100 can also suck outdoor fresh air and send the fresh air into the indoor air 200 through the air supply opening 13 and the air duct structure 300, which is beneficial to improving the freshness of the air environment in the indoor space 200.
Illustratively, as shown in fig. 3, a fresh air port 14 may be further provided on a sidewall of the case 10, and the fresh air port 14 may be in communication with the accommodating chamber 11 for supplementing outdoor air, and may allow the supplemented outdoor air to be introduced into the indoor space 200 (shown in fig. 2) from the air supply port 13 through the filter 30. So that the combined air conditioning unit 100 can circulate filtered air and simultaneously communicate with the outside through the fresh air inlet 14 and supplement fresh air outside the filtered air, thereby being beneficial to improving the oxygen content of the circulated air in the indoor space 200.
In order to facilitate control of whether fresh air is supplied to the indoor space 200, the combined air conditioning unit 100 may include a cut-off electric control valve 41, as shown in fig. 3. In the accommodating chamber 11 in the case 10, a shut-off electric control valve 41 may be installed between the fresh air inlet 14 and the return air inlet 12 and connected to the case 10. The closing of the shut-off electronically controlled valve 41 can be controlled to block the communication between the fresh air vent 14 and the return air vent 12 within the receiving chamber 11. A fan assembly 20 may be installed between the fresh air inlet 14 and the supply air outlet 13 in the flow direction of the air, for example, the fan assembly 20 may be disposed near the supply air outlet 13. Based on this, when the blower assembly 20 is opened and the shut-off electric control valve 41 is closed, fresh air can enter the accommodating cavity 11 from the fresh air inlet 14 under the driving of the blower assembly 20, and can be fed into the indoor space 200 through the air supply inlet 13 and the corresponding air duct structure 300 (shown in fig. 2) to supply fresh air into the indoor space 200.
In this process, the filter 30 may be a filter screen structure having small holes for filtering large particle impurities such as dust and filth from the air flowing through the filter 30. The filter 30 may be a filter device including an adsorbent such as activated carbon, for adsorbing and removing odor and other harmful substances from the air. When the filter is installed, the filter 30 positioned in the accommodating chamber 11 may be installed between the fresh air inlet 14 and the fan assembly in the flow direction of the air so that the fresh air can be filtered through the filter 30 and then introduced into the indoor space 200 through the air outlet 13. Alternatively, a filter may be installed between the blower assembly 20 and the air supply port 13, and the air introduced into the indoor space 200 may be filtered.
In other embodiments, the filter 30 may be provided in a compact structure, and the filter 30 may be installed at the fresh air port 14 and the air supply port 13. In this way, the filter 30 installed at the fresh air inlet 14 can filter fresh air entering the accommodating chamber 11. The filter 30 installed at the air supply opening 13 may filter and remove foreign matters from fresh air or circulated air supplied into the indoor space 200. Alternatively, a filter 30 may be installed at the return air inlet 12 so that air drawn into the accommodating chamber 11 by the indoor space 200 can be filtered and decontaminated by the filter 30.
In order to discharge the dirty gas in the indoor space 200 shown in fig. 2, with continued reference to fig. 3, the tank 10 may further be provided with a dirty air port 15 communicating with the accommodating chamber 11, and the dirty air port 15 may be disposed near the return air port 12. Based on this, the number of fan assemblies 20 may be two, the first fan assembly 20 may be installed near the supply air opening 13, and the second fan assembly 20 may be installed near the sewage air opening 15. For example, the air outlet side of the second fan assembly 20 may be disposed toward the air inlet 15, and the second fan assembly 20 may be turned on under the condition that the shut-off electric control valve 41 is closed to prevent the air return opening 12 from communicating with the air supply opening 13, so that the air in the indoor space 200 may be discharged through the air duct structure 300, the air return opening 12, and the air inlet 15. In this process, the first fan assembly 20 may be turned on, so that fresh air may be introduced into the indoor space 200 through the fresh air inlet 14, the filter 30, the air outlet 13 and the air duct structure 300, which is beneficial to supplementing the oxygen content in the indoor space 200.
To facilitate control of the fresh air port 14 and the dirty air port 15, the combined air conditioning unit 100 may further include a fresh air control valve 42 and a dirty air control valve 43, as shown in fig. 3. Illustratively, a fresh air control valve 42 may be mounted at the fresh air vent 14 and coupled to the housing 10 for controlling the opening and closing of the fresh air vent 14. A sewage wind control valve 43 may be installed at the sewage wind gap 15 and connected with the case 10 for controlling the opening and closing of the sewage wind gap 15. Based on this, the fresh air electric control valve 42 and the dirty air electric control valve 43 may be simultaneously closed, and the shut-off electric control valve 41 may be opened, so that air may circulate in the indoor space 200 (shown in fig. 2), one of the duct structures 300, the accommodating chamber 11, the other duct structure 300, and the indoor space 200.
The fresh air electric control valve 42 and the dirty air electric control valve 43 can be completely opened, and the cut-off electric control valve 41 can be closed at the same time, so that the fresh air can be supplemented to the indoor space 200, and the dirty air in the indoor space 200 can be extracted and discharged. The opening degrees of the shutoff electric control valve 41, the fresh air electric control valve 42, and the dirty air electric control valve 43 may be flexibly adjusted as needed, and the present invention is not limited thereto.
The opening degrees of the return air port 12 and the air supply port 13 are controlled for convenience. An electric control valve for air return can also be arranged at the position of the air return inlet 12 and used for controlling the opening, closing and opening of the air return inlet 12. Correspondingly, an air supply electric control valve can be arranged at the air supply opening 13 and used for controlling the opening, closing and opening of the air supply opening 13.
For the fan assembly 20, the fan assembly 20 may be a split structure, for example, the motor and the fan impeller may be driven by a belt, so that the motor may drive the impeller to rotate, and thus the air in the accommodating cavity 11 flows. The motor can drive the fan impeller to rotate in a gear meshing mode. So as to adjust the speed ratio of the motor and the fan impeller. In addition, the fan assembly 20 may be an integral structure, that is, the fan impeller may be directly mounted on the rotating shaft of the motor, so that the motor may directly rotate the fan impeller through rotation. The fan assembly 20 may be any of a centrifugal structure, an axial flow structure, a cross flow structure, or an oblique flow structure, and in the accommodating cavity 11, the fan assembly 20 may be flexibly arranged according to requirements, so as to provide power for flowing air, which is not limited.
Since the combined air conditioning unit 100 may also dehumidify, heat or cool the air flowing therethrough, the combined air conditioning unit 100 may need to cool or heat the air flowing therethrough during this process.
In order to improve the heat exchange efficiency between the combined air conditioning unit 100 and the air, as shown in fig. 4, the combined air conditioning unit 100 may further include a compression heat exchange assembly 50, and the compression heat exchange assembly 50 may include a compressor 51, a four-way valve 52, a first heat exchanger 53, a throttle device 54, and a second heat exchanger 55. Illustratively, the four-way valve 52 may have four ports A, B, C and D, the inlet end of the compressor 51 may be connected to the a-end of the four-way valve, and the outlet end of the compressor 51 may be connected to the B-end of the four-way valve. The C-terminal of the four-way valve may be connected to one end of the first heat exchanger 53, the other end of the first heat exchanger 53 may be connected to one end of the second heat exchanger 55 through the throttle 54, and the other end of the second heat exchanger 55 may be connected to the D-terminal of the four-way valve.
Based on this, the refrigerant can circulate between the first heat exchanger 53 and the second heat exchanger 55 and generate a reversible phase change, and the refrigerant can release or absorb heat while generating a phase change so that heat can circulate between the first heat exchanger 53 and the second heat exchanger 55. For example, the refrigerant may exchange heat with air at the first heat exchanger 53, thereby releasing heat to heat ambient air (or absorbing heat to cool nearby air). And the refrigerant may also exchange heat at the second heat exchanger 55, thereby absorbing heat to cool the nearby medium (or release heat to heat the nearby medium).
For example, when compression heat exchange assembly 50 is in a cooling or dehumidifying condition, four-way valve 52 may be adjusted to turn on port B and port C and to turn on port D and port a, in conjunction with fig. 4. So that the refrigerant can circulate between the compressor 51, the ports B and C of the four-way valve 52, the first heat exchanger 53, the throttle device 54, the second heat exchanger 55, the ports D and a of the four-way valve 52, and the compressor 51, i.e., in the direction indicated by the solid arrows in fig. 4. In this process, the high-pressure gaseous refrigerant compressed by the compressor 51 may flow to the first heat exchanger 53 so that the refrigerant may liquefy and release heat at the first heat exchanger 53. Then, the pressure of the liquid-phase refrigerant flowing into the second heat exchanger 55 is reduced by the throttle device 54 so that the refrigerant can absorb heat and vaporize at the second heat exchanger 55, thereby cooling the medium near the second heat exchanger 55 and effecting heat exchange transfer between the first heat exchanger 53 and the second heat exchanger 55.
With continued reference to FIG. 4, when the compression heat exchange assembly 50 is in a heating mode, the four-way valve 52 may be adjusted to allow port B to be in communication with port D and port C to be in communication with port A. In this way, the refrigerant can circulate between the compressor 51, the ports B and D of the four-way valve 52, the second heat exchanger 55, the throttle device 54, the first heat exchanger 53, the ports C and a of the four-way valve 52, and the compressor 51, i.e., in the direction indicated by the broken-line arrows in fig. 4. In this process, the high-pressure gaseous refrigerant compressed by the compressor 51 may flow to the second heat exchanger 55 so that the refrigerant may liquefy at the second heat exchanger 55 and release heat for heating the medium near the second heat exchanger 55. Then, the pressure of the liquid-phase refrigerant flowing into the first heat exchanger 53 is reduced by the throttle device 54 so that the refrigerant can absorb heat at the first heat exchanger 53 and vaporize, for cooling the medium around the first heat exchanger 53 to effect heat exchange transfer between the first heat exchanger 53 and the second heat exchanger 55.
In other embodiments, a four-way valve may not be provided, for example, the air outlet end of the compressor 51 may be connected to the first heat exchanger 53, and the air inlet end of the compressor 51 may be connected to the second heat exchanger 55, so that the refrigerant may circulate among the compressor 51, the first heat exchanger 53, the throttling device 54, the second heat exchanger 55, and the compressor 51. At this time, the first heat exchanger 53 may be used to heat the nearby medium and the second heat exchanger 55 may be used to cool the nearby medium so that the compression heat exchange assembly 50 may be operated in a cooling or dehumidifying condition, i.e., a single cooling mode.
In the above embodiment, the throttle device 54 may be a capillary tube structure or an electronic expansion valve structure. In addition, the throttling device 54 may be a diverter with a throttling function installed close to the first heat exchanger 53, or a diverter may be installed between the throttling device 54 and the first heat exchanger 53, so that two-phase refrigerant under the heating condition may uniformly flow to a plurality of refrigerant branches in the first heat exchanger 53 through the diverter, which is beneficial to improving the overall heat exchange efficiency of the first heat exchanger 53.
As for the compressor 51, as shown in fig. 5, the compressor 51 may include a compressor body 511, a gas-liquid separator 512, and an oil separator 513, the compressor body 511 having an inlet end and an outlet end. The gas-liquid separator 512 is connected between the port a of the four-way valve 52 and the air inlet end of the compressor body 511, and when the gas-phase refrigerant mixed with the liquid impurities or the solid impurities flows to the air inlet end of the compressor body 511 through the gas-liquid separator 512, the gas-liquid separator 512 can separate the liquid impurities (which may include the liquid-phase refrigerant) or the solid impurities, so as to avoid that the impurities enter the compressor body 511 to affect the stable operation of the compressor body 511. The outlet end of the compressor main body 511 and the four-way valve 52 can be communicated through the oil separator 513, and the compressed gas-phase refrigerant can separate the mixed lubricating oil when flowing through the oil separator 513, so that the lubricating oil is prevented from adhering to the inner walls of the first heat exchanger 53 and the second heat exchanger 55 when flowing through the first heat exchanger 53 and the second heat exchanger 55, and the heat exchange efficiency between the refrigerant and other mediums at two sides of the heat exchangers is affected.
When the compressor 51 includes the compressor main body 511, the gas-liquid separator 512, and the oil separator 513 at the same time, an end of the gas-liquid separator 512, which is close to the end far from the compressor main body 511, may serve as an air inlet end of the compressor 51, and an end of the oil separator 513, which is far from the compressor main body 511, may serve as an air outlet end of the compressor 51, in the flow direction of the refrigerant. Further, the gas-liquid separator 512 and the oil separator 513 may be optionally installed at both ends of the compressor body 511 as needed. Alternatively, the inlet end of the compressor body 511 may be directly connected to the port a of the four-way valve 52, and the outlet end of the compressor body 511 may be directly connected to the port B of the four-way valve 52. This is not limited thereto.
In this way, as shown in fig. 6, the second heat exchanger 55 can be mounted in the housing chamber 11, and the second heat exchanger 55 can be mounted in connection with the inner wall of the case 10. For example, the second heat exchanger 55 may be installed at a side of the filter 30 near the supply port 13 in the flow direction of the air. In the air flow direction, a filter 30 having a screen structure is installed between the fan assembly 20 and the fresh air port 14, for example, between the fan assembly 20 and the fresh air port 14, which are disposed near the air supply port 13. Fresh air can enter the accommodating cavity 11 through the fresh air port 14, can flow through the filter 30 to be filtered, then flows through the second heat exchanger 55 to exchange heat, and finally is sent into the room through the air supply port 13. The fresh air electric control valve 42 and the sewage air electric control valve 43 can be closed, so that indoor air enters the accommodating cavity 11 from the air return opening 12 under the drive of the fan assembly 20, is filtered by the filter 30 and exchanges heat with the second heat exchanger 55, and the treated air can be returned to the room from the air supply opening 13.
As such, the first heat exchanger 53 in fig. 4 may be installed as an outdoor heat exchanger in a position where air circulates, for example, the compression heat exchange assembly 50 may further include a heat exchange fan for driving air to rapidly flow through the first heat exchanger 53. The refrigerant can circulate in the refrigerant passage of the compression heat exchange assembly under the action of the compressor 51. For example, when the combined air conditioning unit 100 is in a dehumidification or a refrigeration condition, the refrigerant may liquefy as it flows through the first heat exchanger 53 to release heat to the air adjacent to the first heat exchanger 53. Then, the liquid-phase refrigerant may flow to the second heat exchanger 55 in the accommodating chamber 11 shown in fig. 6, and the liquid-phase refrigerant may be vaporized in the second heat exchanger 55 and absorb heat of the air flowing through the second heat exchanger 55, so as to cool the air flowing through the second heat exchanger 55 to the air supply port 13, thereby achieving the purpose of cooling or dehumidifying the air. Similarly, the compression heat exchange assembly 50 in the heating mode can also heat the air flowing to the air supply opening 13 through the second heat exchanger 55. In other embodiments, the second heat exchanger 55 may be a plate heat exchanger, where two heat exchanging channels that are isolated from each other and can exchange heat are provided, and one of the heat exchanging channels may be connected between the throttle device 54 and the port D of the four-way valve 52. The compression heat exchange assembly 50 may further include a third heat exchanger and a circulation pump, wherein two ends of the third heat exchanger may be correspondingly communicated with two ends of the other heat exchange channel, and the circulation pump may be connected between the third heat exchanger and the other heat exchange channel, so that coolant such as water, oil, etc. may circulate between the second heat exchange channel and the third heat exchanger by driving the circulation pump, so that heat may be rapidly exchanged between the second heat exchanger 55 and the third heat exchanger. At this time, a third heat exchanger for heating, cooling or dehumidifying the air flowing from the air supply port 13 into the room may be installed in the accommodating chamber 11. Correspondingly, other parts of the compression heat exchange assembly 50 except the third heat exchanger can be integrated into an outdoor unit structure and connected and communicated with the third heat exchanger in the box 10 through a coolant circulation pipeline, so that a larger installation distance can be provided between the box 10 and the outdoor unit structure.
Because the compression heat exchange assembly 50 has a higher efficiency ratio, for the combined air conditioning unit 100, in the process of performing heating treatment, cooling treatment or dehumidifying treatment on indoor air, the compression heat exchange assembly 50 provides a heat source or a cold source, so that the heating and refrigerating efficiency of the combined air conditioning unit 100 is remarkably improved, a large amount of energy sources can be saved, and the cost-effectiveness ratio is high.
It should be noted that, for the second heat exchanger 55 or the third heat exchanger installed in the accommodating chamber 11, it may be installed at another position of the accommodating chamber 11, for example, disposed near the air supply port 13, or two second heat exchangers 55 connected in series are installed at the fresh air port 14 and the air return port 12, so long as the air can exchange heat with the second heat exchanger 55 or the third heat exchanger before flowing into the air supply port 13. In addition, an electric heater (e.g., an infrared heater or a resistance heater, etc.) may be installed in the accommodating chamber 11 near the second heat exchanger 55 or the third heat exchanger, thereby increasing the heating power of the combined air conditioning unit 100. An electric heater may be installed in the accommodating chamber 11 alone so that the combined air conditioner unit 100 may heat the air fed into the indoor space 200.
As shown in fig. 2, the combined air conditioning unit 100 can communicate with the indoor space 200 through the two air duct structures 300, so that air can circulate in the relatively airtight circulation channel. Based on this, according to different working condition demands, referring to fig. 6, the combined air conditioning unit 100 may cool or heat the air in the accommodating chamber 11 through the second heat exchanger 55. Based on this, it is necessary for the case 10 enclosing the accommodation chamber 11 to have a superior airtight and heat-insulating ability. Correspondingly, the duct structure 300 is also required to have better air tightness and heat insulation capability.
In order to make the case 10 shown in fig. 6 have a better air tightness, i.e., solve the problem of sealing installation of the case 10. As shown in fig. 7, fig. 7 is a schematic perspective view of the case 10 shown in fig. 6. The case 10 may be a frame type structure, and the case 10 includes a plurality of frame brackets 16 and a plurality of panel assemblies 17. For example, a plurality of frame supports 16 may be connected to form a frame having a substantially rectangular parallelepiped structure, a square structure, a triangular prism structure, a triangular pyramid structure, or a polygonal prism structure. With the case 10 having a rectangular parallelepiped structure, the number of the frame supports 16 may be twelve, and eight frame supports 16 may be connected to form two identical rectangular frames. The two rectangular frames may be opposed so that the other four side frames 16 may be connected in one-to-one correspondence with the four right angles on each rectangular frame to form a frame of rectangular parallelepiped structure. The number of the panel assemblies 17 may be six, and the six panel assemblies 17 may be six side walls of the rectangular parallelepiped frame, that is, two adjacent panel assemblies 17 are perpendicular to each other, and the panel assemblies 17 are approximately rectangular plate structures. The plate shape of some or all of the panel assemblies 17 may be adjusted according to different frames formed by the plurality of frame supports 16.
As shown in fig. 8, fig. 8 is a schematic perspective view of a panel assembly 17 shown in fig. 7. The case may further include a plurality of first sealing strips 18, and one first sealing strip 18 may be attached at least one edge of one panel assembly 17. Taking a panel body in which the panel assembly 17 is of an integral structure as an example, a first sealing strip 18 may be attached to one side of the panel body at one of edges of the panel assembly 17. When the panel assemblies 17 are mounted in a connected state, two adjacent vertically disposed panel assemblies 17 can be mounted in a connected state by the frame bracket 16. As shown in fig. 9, fig. 9 is a sectional view of a first partial structure of the case 10 shown in fig. 7. The frame support 16 may include a first connection plate 161 and a second connection plate 162, and the first connection plate 161 and the second connection plate 162 are vertically connected and form the frame support 16 of an elongated structure, which is approximately in the shape of an angle iron. The first connecting plate 161 may be installed in connection with the edge of one of the panel assemblies 17 provided with the first sealing strip 18, and the first sealing strip 18 may be installed between the panel assembly 17 and the first connecting plate 161 in a pressing manner, and the second connecting plate 162 may be installed in connection with the edge of the other panel assembly 17, and the first sealing strip 18 on the panel assembly 17 may be installed between the panel assembly 17 and the second connecting plate 162 in a pressing manner.
The first sealing strip 18 may be a strip-shaped structure made of a flexible material or an elastic material, for example, the flexible material may include polyvinyl chloride, rubber, silica gel, plastic with lower hardness, and the like. In this way, by pressing the first sealing strip 18, a sealed connection between the panel assembly 17 and the first connection plate 161 or the second connection plate 162 can be achieved, that is, a better airtight connection between two mutually perpendicular panel assemblies 17 can be achieved by the cooperation of the first sealing strip 18 and the frame support 16. In this way, each panel assembly 17 and the frame support 16 can be in sealing connection through the first sealing strip 18, so that the enclosed box 10 has better air tightness, and the influence of the pressure release of the box 10 on the air circulation flow effect of the combined air conditioner unit 100 is avoided.
In the related technical scheme, when the frame support and the panel assembly are connected, heat-insulating sealing cotton is placed between the frame support and the panel assembly, and is extruded and installed between the frame support and the panel assembly for sealing connection of the frame support and the panel assembly. However, since the heat-insulating sealing cotton is an independent member with respect to the frame support and the panel assembly, in the process of connecting the frame support and the panel assembly, the heat-insulating sealing cotton with a proper length is required to be cut and placed on the frame support and the panel assembly, and then the frame support and the panel assembly are connected and extruded, so that the installation step is complicated.
However, in the present embodiment, since the first sealing bar 18 is attached to the edge of the panel assembly 17, the side of the panel assembly 17 where the first sealing bar 18 is disposed may be directly and closely disposed toward the first connection plate 161 or the second connection plate 162 shown in fig. 9 during the process of attaching the panel assembly 17 and the frame support 16, and then the panel assembly 17 and the frame support 16 may be attached by screws or rivets, and the first sealing bar 18 may be press-sealed between the panel assembly 17 and the frame support 16. In the mounting process, the additional steps of cutting the first sealing strip 18 and positioning and placing the first sealing strip 18 are not needed, which is beneficial to simplifying the sealing connection operation steps of the panel assembly 17 and the frame support 16 so as to improve the sealing assembly efficiency of the box body 10.
In addition, with continued reference to fig. 9, the case 10 may further include a second sealing strip 19, where the second sealing strip 19 may be a separate member made of a flexible material such as polyvinyl chloride, rubber, silicone, a relatively low durometer plastic, or foam. In the process of connecting the bezel support 16 and the panel assembly 17, it is also possible to cut a second sealing strip 19 of a suitable length and place the second sealing strip 19 between the panel assembly 17 and the bezel support 16, and then connect the panel assembly 17 and the bezel support 16 to simultaneously compress the second sealing strip 19 and the first sealing strip 18, thereby improving the airtight connection effect between the panel assembly 17 and the bezel support 16.
In connecting the panel assembly 17 and the first sealing strip 18, it is possible to provide that the panel assembly 17 and the first sealing strip 18 are of a unitary structure. Illustratively, taking the example that the panel body of the panel assembly 17 is made of polyvinyl chloride, rubber or plastic, which is a hard material, the materials of the first sealing strip 18 and the panel body may be the same, and the first sealing strip 18 and the panel assembly 17 may be connected by an integral molding, a heat melting or an ultrasonic welding process, etc., so that the first sealing strip 18 may be an integral structure connected to the edge of the panel assembly 17. Based on this, the first sealing tape 18 and the panel body may be treated so that the hardness of the panel body is greater than that of the first sealing tape 18. The panel main body having a large hardness can be used as a side wall plate of the case 10, and the first sealing strip 18 having a small hardness can have a good sealing effect by being installed by pressing.
Furthermore, the first sealing strip 18 and the panel assembly 17 may also be connected by plugging. As shown in fig. 10, fig. 10 is a cross-sectional view of a partial structure at A-A shown in fig. 8. A positioning groove 171 may be provided at a position of the panel assembly 17 near the edge. Correspondingly, the first sealing strip 18 may be connected with a plugging portion 181 corresponding to the positioning groove 171. The plug portion 181 is inserted into the positioning groove 171 to achieve positioning connection of the first sealing strip 18 and the panel assembly 17. The positioning groove 171 may be a groove structure extending parallel to the adjacent edge line, and the plugging portion 181 may be a corresponding plugging column or a strip structure extending along the length direction of the first sealing strip 18. Alternatively, the positioning groove 171 may be a plurality of insertion holes formed at intervals along a direction parallel to the adjacent edge line, and the insertion portion 181 may be a plurality of insertion posts corresponding to the insertion holes. Or, the inner diameter of the positioning groove 171 far from the bottom of the first sealing strip 18 may be larger than the inner diameter of the positioning groove 171 near to the opening of the first sealing strip 18, and the plugging portion 181 may be matched with the shape of the positioning groove 171, when the plugging portion 181 is inserted into the positioning groove 171, the plugging portion 181 may be limited to be separated from the positioning groove 171, so that the first sealing strip 18 may be stably connected with the panel assembly 17.
As for the panel assembly 17, taking an example in which the case 10 is of a rectangular parallelepiped structure and the panel assembly 17 is a flat rectangular parallelepiped plate material, a side of the panel assembly 17 mounted on the case 10 facing the accommodating chamber 11 is defined as an inner side thereof, and the opposite side is an outer side of the panel assembly 17, i.e., both side surfaces of the panel assembly 17. The other four faces of the corresponding panel assembly 17 may be end faces of the panel assembly 17.
Based on this, as shown in fig. 11, fig. 11 is a sectional view of a second partial structure of the case 10 shown in fig. 7. The frame support 16 may be a tubular structure having a rectangular or oblong cross-section. At this time, the first sealing tape 18 may be attached to one to four end surfaces of the panel assembly 17, i.e., the first sealing tape 18 corresponds to an edge attached to the end surface. In this way, the end surface of the panel assembly 17, to which the first sealing strip 18 is connected, may be close to one side of the frame support 16 of the tubular structure (such as a square tube), and the frame support 16 and the panel assembly 17 may be connected by welding, bonding, clamping or screwing, so that the first sealing strip 18 installed on the frame support 16 and the panel assembly 17 in an extrusion manner has a better sealing effect.
Further, as shown in fig. 12, fig. 12 is a sectional view of a third partial structure of the case shown in fig. 7. The first straight direction (i.e., X direction) may be defined to be parallel to the inner side or the outer side of the panel assembly 17, and when the panel assembly 17 is mounted at different positions of the case 10 shown in fig. 7, the first straight direction may also be adjusted according to the different positions of the panel assembly 17, for example, two panel assemblies 17 of the case 10 having a rectangular parallelepiped structure, which are distributed in opposite directions, may have the same first straight direction. Based on this, the panel assembly 17 may have two oppositely disposed edges in the first straight direction, and the two oppositely disposed edges may each have one first sealing strip 18.
The first sealing strip 18 may be mounted on two opposite end surfaces of the panel assembly 17 in the X direction, or one first sealing strip 18 may be mounted on an inner side surface of the panel assembly 17 near two opposite edges. It is also possible to mount one first sealing strip 18 on the inner side surface of the panel assembly 17 near one of the above edges, and mount the other first sealing strip 18 on the opposite other end surface in the X direction. Subsequently, the panel assembly 17 may be coupled between the two spaced apart frame brackets 16 in a first straight direction such that opposite sides of the panel assembly 17 may be coupled with the two frame brackets 16 and press the two first sealing bars 18. Since the frame support 16 shown in fig. 12 may have both rectangular tube and angle iron structure characteristics, the end surface or side surface at the edge of the panel assembly 17 may be connected close to the frame support 16, and the corresponding first sealing strip 18 is pressed to satisfy the airtight connection effect.
In addition to having a high requirement for air tightness, the case 10 needs to have a high heat insulating capability because the air circulating in the case 10 needs to be heated or cooled. Based on this, as shown in fig. 13, fig. 13 is a first sectional view of the panel assembly 17 in the case 10 shown in fig. 7. The panel assembly 17 may include two positioning frames 172, a first panel 173, and a second panel 174, and the two positioning frames 172 may be spaced apart along an X direction, which may be perpendicular to an extending direction of the two positioning frames 172. The first panel 173 has opposite ends (i.e., two opposite edges) in the X direction, one end of the first panel 173 may be connected to one of the positioning frames 172, and the other end of the first panel 173 may be connected to the other positioning frame 172. The second panel 174 also has opposite ends (i.e., two opposite edges) in the X-direction, and one end of the second panel 174 may be connected to one of the positioning frames 172 and the other end of the second panel 174 may be connected to the other positioning frame 172. It should be noted that, taking the direction perpendicular to the first panel 173 as the Y direction (i.e., the second straight direction) as an example, the Y direction is perpendicular to the X direction, and the first panel 173 and the second panel 174 are disposed to be spaced apart in the Y direction, so that a cavity structure can be defined between the two positioning frames 172, the first panel 173 and the second panel 174.
Based on this, taking the example that the second panel 174 is located on two opposite sides of the first panel 173 and the accommodating cavity 11 (as shown in fig. 6) along the Y direction, the first panel 173 is an inner side surface of the panel assembly 17, and the corresponding second panel 174 is an outer side surface of the panel assembly 17. In this way, the cavity structure between the first panel 173 and the second panel 174 can prevent heat from being transferred between the accommodating chamber 11 and the external space in the Y direction, i.e., heat transfer efficiency can be reduced by air in the cavity structure to improve heat preservation and insulation effects of the case 10.
With continued reference to fig. 13, when the panel assembly 17 and the bezel support 16 (as shown in fig. 7) are connected in a sealed manner, since the two positioning frames 172 correspond to two opposite edges of the panel assembly 17 along the X direction, two first sealing strips 18 may be disposed in one-to-one correspondence with the two positioning frames 172, that is, one positioning frame 172 may be connected with one first sealing strip 18. In this way, the two oppositely disposed positioning frames 172 may be disposed in one-to-one correspondence with the two frame supports 16, and one positioning frame 172 may be connected with one frame support 16, so that the first sealing strip 18 is installed on the frame support 16 and the positioning frame 172 support in a pressing manner, so as to realize the sealing connection between the heat-insulating panel assembly 17 and the two frame supports 16.
The positioning frame 172 may extend along a third linear direction, where the third linear direction, the first linear direction, and the second linear direction are perpendicular to each other. Wherein, the cross section of the positioning frame 172 may be an angle iron-like structure. Such as the positioning frame 172, the first panel 173, and the second panel 174 may be made of a metal material and connected by welding, screw connection, or rivet connection. If the first panel 173 and the second panel 174 are hollow, wavy reinforcing ribs may be rolled on the first panel 173 and the second panel 174 to improve the bending resistance of the first panel 173 and the second panel 174.
Further, as shown in fig. 14, fig. 14 is a second sectional view of the panel assembly 17 in the case 10 shown in fig. 7. For example, the positioning frame 172 may include a first connecting plate 1721, a second connecting plate 1722, and a first carrier 1723, and the first connecting plate 1721, the second connecting plate 1722, and the first carrier 1723 may all extend along a third linear direction. Wherein the first connection plate 1722 may be disposed perpendicular to the Y direction. Along the X direction, one end of the first connecting plate 1721 may be connected to the second connecting plate 1722 vertically, and the other end of the first connecting plate 1721 may be connected to the first carrier 1723. Based on this, when the two positioning frames 172 are arranged at intervals in the X direction, the two second connection plates 1722 may be spaced apart and distributed relatively in the X direction. In this way, the two first connection plates 1721 and the two first carriers 1723 may be located between the two second connection plates 1722, and the two first connection plates 1721 may be located on the same side of the two second connection plates 1722 in the Y direction. The first panel 173 may be connected to the two first carriers 1723 along a first straight line direction, and the second panel 174 may be connected to one ends of the two second connection plates 1722 away from the first connection plate 1721 along the first straight line direction, so that the first panel 173 and the second panel 174 are spaced apart along the Y direction.
When the first panel 173 and the first carrier 1723 are connected, the first carrier 1723 is connected to the end of the first connecting plate 1721 away from the second connecting plate 1722 along the X direction. Along the Y direction, the first carrier 1723 and the second connecting plate 1722 may be connected to the same side of the first connecting plate 1721. With continued reference to fig. 14, in the same positioning frame 172, along the X direction, a first slot 1724 may be formed on an end surface of the first carrier 1723 away from the second connecting plate 1722. In the two positioning frames 172 of the same panel assembly 10 (as shown in fig. 12) that are spaced apart along the X direction, the opening of one first slot 1724 may be disposed towards the opening of the other first slot 1724, and both the first slots 1724 may extend along the third straight direction, so that opposite ends of the first panel 173 along the X direction may be inserted into the two first slots 1724 for positioning and mounting the first panel. At this time, the first sealing strip 18 and the first carrier 1723 may be connected to opposite sides of the first connecting plate 1721 along the Y direction. The first sealing strip 18 may be attached to a side of the second connecting plate 1722 away from the first connecting plate 1721 in the X direction. May be used to sealingly connect the positioning frame 172 to the bezel support 16.
In addition, the first carrier 1723 may be installed on a side of the first connecting plate 1721 away from the second connecting plate 1722 along the Y direction. At this time, the first sealing strip 18 needs to be mounted on the side of the second connecting plate 1722 away from the first connecting plate 1721 in the X direction.
In other embodiments, the positioning frame 172 may not be provided with the first carrier 1723. At this time, along the X direction, a first slot 1724 may be formed on the end surface of the first connection plate 1721 away from the second connection plate 1722, which may also be used for plugging and installing the first panel 173.
When the second panel 174 is connected, as shown in fig. 14, at an end of the second connecting plate 1722 remote from the first connecting plate 1721 in the Y direction, opposite ends of the second panel 174 in the X direction may be contact-connected with the end of the second connecting plate 1722. The second panel 174 and the second connecting plate 1722 may be connected by welding, bonding, heat-melting, screw connection, or the like, and for the connection, a corresponding selection may be made according to the material of the second panel 174 and the second connecting plate 1722.
In addition, the second panel 174 and the positioning frame 172 may be connected by a slot. As shown in fig. 15, fig. 15 is a cross-sectional view of the second panel 174 and the positioning frame 172 shown in fig. 14 connected by a slot. The positioning frame 172 may further include a second carrier 1725, where the second carrier 1725 may be connected to an end of the second connecting plate 1722 away from the first connecting plate 1721 along the Y direction. For example, the second carrier 1725 and the first connecting plate 1721 may be located on the same side of the second connecting plate 1722 along the X direction, or the second carrier 1725 and the first connecting plate 1721 may be located on opposite sides of the second connecting plate 1722 along the Y direction. Along the X direction, a second slot 1726 may be formed on an end surface of the second carrier 1725 facing the other positioning frame 172, so that the two second slots 1726 of the two positioning frames 172 may be oppositely disposed along the X direction, for receiving opposite ends of the second panel 174 along the X direction in a plugging manner.
It should be noted that, in order to improve the heat insulation effect of the panel assembly 17, the positioning frame 172 may be made of hard materials such as polyvinyl chloride, rubber or plastic, so as to have a better heat insulation effect, thereby preventing heat from being transferred inside and outside the case 10 along the Y direction through the positioning frame 172.
On this basis, in order to improve the structural strength of the positioning frame 172, as shown in fig. 15, a connecting cavity 1727 may be formed in the first connecting plate 1721 and the second connecting plate 1722 of the positioning frame 172. A portion of the connection cavity 1727 may be located at an end of the first connection plate 1721 near the second connection plate 1722 along the X direction, and another portion of the connection cavity 1727 may be located at an end of the second connection plate 1722 near the first connection plate 1721 along the Y direction, and the two portions of the connection cavity 1727 are connected. In the connecting cavity 1727, a reinforcing member 1728 may be embedded, and the reinforcing member 1728 may completely fill the connecting cavity 1727 to improve the structural strength of the positioning frame 172. Illustratively, the reinforcement 1728 may be approximately a vertically connected L-shaped structure. The reinforcement 1728 may be made of a metal material such as a steel plate or an aluminum alloy, or may be made of other non-metal materials, and may have a higher structural strength than the first connecting plate 1721 and the second connecting plate 1722.
As for the panel assembly 17, as shown in fig. 16, fig. 16 is a sectional view of the panel assembly 17 and the frame bracket 16 in the case 10 shown in fig. 7. The panel assembly 17 may further include a thermal insulation layer 175, and the thermal insulation layer 175 may be filled between the first panel 173 and the second panel 174 along the Y direction, so as to reduce the thermal conductivity coefficient of the panel assembly 17 for heat transfer along the Y direction, which is beneficial to improving the thermal insulation effect of the panel assembly 17. The heat insulating layer 175 may be a material with good heat insulating effect, such as heat insulating cotton, foaming agent or glass fiber. If the space between the first panel 173 and the second panel 174 is filled with the foaming agent and forms the heat insulation layer 175, the heat insulation layer 175 can also contact and adhere the first panel 173, the second panel 174 and the two positioning frames 172 due to the better adhesion property of the heat insulation layer 175, so as to improve the connection stability of the panel assembly 17.
For the first carrier 1723, as shown in fig. 17, fig. 17 is a partially enlarged view at B in fig. 16. The first carrier 1723 may be regarded as a plate with a larger thickness, and the first slot 1724 may be formed on an end surface of the first carrier 1723 away from the second panel 174 along the Y direction. Alternatively, the first carrier 1723 may be a plate with a smaller thickness, and may be bent to form the first slot 1724. Along the X direction, between the two positioning frames 172 that are arranged at intervals, two first carriers 1723 may be connected between the two first connection plates 1721, and an end of the first connection plate 1721 away from the second connection plate 1722 may be connected with the first carriers 1723 perpendicularly, so that the first slots 1724 and the first carriers 1723 may extend along the third straight line direction. Correspondingly, the first panel 173 may include an inner panel body 1731 and two inner panel edges 1732, the two inner panel edges 1732 may be located at opposite sides of the inner panel body 1731 in the X-direction, and the inner panel edges 1732 may be vertically bent toward the second panel 174 in the Y-direction to form a burring structure. In this way, the inner plate edges 1732 of the two flanging structures may correspond to the two first slots 1724 one by one, and one inner plate edge 1732 may be inserted into one first slot 1724 along the Y direction for positioning and connecting the first panel 173 and the two positioning frames 172.
With continued reference to fig. 17, a first sealing strip 18 extending in a third linear direction may be connected to the first connecting plate 1721, and the first sealing strip 18 is located on a side of the first connecting plate 1721 away from the second panel 17 (as shown in fig. 16) in the Y direction. Based on this, when the first connection plate 1721 is connected close to the bezel bracket 16 at a side distant from the second panel 174 in the Y direction, the first sealing strip 18 may be press-fitted between the bezel bracket 16 and the first connection plate 1721 in the Y direction, thereby satisfying the sealing connection of the panel assembly 17 and the bezel bracket 16. In addition, in the X direction, a sufficient space may be reserved on a side of the first sealing strip 18 away from the first panel 173 for installing the extruded second sealing strip 19 between the frame bracket 16 and the first connecting plate 1721, so as to further improve the sealing effect between the first connecting plate 1721 and the frame bracket 16 in cooperation with the first sealing strip 18.
As for the installation position of the first weather strip 18, as shown in fig. 17, since the inner panel body 1731 may be located at a side of the first connecting plate 1721 away from the second panel 174 (as shown in fig. 16) in the Y direction, the inner panel body 1731 is arranged at a distance from the first connecting plate 1721 in the Y direction, such as approximately in a stepped structure. Along the X-direction, one side edge of the first sealing strip 18 may be connected to the first connecting plate 1721, and the other side edge of the first sealing strip 18 may be disposed toward the inner panel body 1731 such that the perpendicular projection of the inner panel body 1731 and the first sealing strip 18 in the Y-direction in the plane of the second panel 174 at least partially coincides. Thus, when the first sealing strip 18 is at least partially press-fitted between the frame bracket 16 and the first connection plate 1721, the first sealing strip 18 can be supportably connected between the first connection plate 1721 and the first panel 173. For example, the first sealing strip 18 may be supportably connected between the first connecting plate 1721 and the inner plate edge 1732 to achieve a sealed connection between the first connecting plate 1721 and the frame support 16 by elastic deformation of the first sealing strip 18. In addition, the first sealing strip 18 may also be supportably connected between the first connecting plate 1721 and the inner plate body 1731, and may also be used to limit the degree of freedom of the first panel 173 in the Y direction while sealing the first connecting plate 1721 to the frame support 16.
When the positioning frame 172 and the second panel 174 are connected, as shown in fig. 18, fig. 18 is a partially enlarged view at C in fig. 16.
