However, these exemplary embodiments can be implemented in various different forms, and should not be interpreted as being limited only to the embodiments set forth herein. It should be understood that these embodiments are provided in order to make the present disclosure complete and comprehensive, and to adequately convey the ideas of these exemplary embodiments to those of ordinary skill in the art. In the drawings, the thickness of layers and regions can be exaggerated for clarity, and the same reference numerals are used to denote the same elements, so that a description thereof will be omitted.

[0036] In conjunction with Figures 1 to 6 As shown, according to a specific embodiment of the present application, an explosion suppression device for an air conditioning system is provided.

[0037] Specifically, the explosion suppression device comprises a shell 1, a first air door 2, a second air door 3 and an air inducer 4. The shell 1 is provided with a containing cavity for containing a refrigeration module, and is provided with a first air port and a second air port on a side wall, which are communicated with the containing cavity respectively. The first air door 2 is movably connected with the shell 1, and has a first blocking position for blocking the first air port and a first avoiding position for avoiding the first air port. The second air door 3 is movably connected with the shell 1, and has a second blocking position for blocking the second air port and a second avoiding position for avoiding the second air port. The air inducer 4 is connected at the first air port, the first air door 2 is located at an air outlet side of the air inducer 4, and the air inducer 4 is used for driving airflow to flow so as to blow the first air door 2 to move to the first avoiding position.

[0038] In the embodiment of the present application, the shell 1 is provided with the first air port and the second air port, the first air door 2 is arranged at the first air port, the second air door 3 is arranged at the second air port, the air inducer 4 drives airflow to flow so as to blow the first air door 2 to move to avoid the first air port, and then the outside air enters the shell 1 to dilute the gas concentration in the shell 1, and the diluted gas is discharged through the second air port; when the gas is high in concentration, the shell 1 is in a sealed state, the gas is diluted and discharged through the air door, and the safety explosion suppression is realized; the air inducer 4 can drive airflow to flow according to the gas concentration in the shell 1, can quickly and actively respond to the change of the gas concentration in the shell 1, and can eliminate the risk in time. The explosion suppression device in the above scheme solves the technical problems of slow explosion suppression response and low safety of the existing air conditioning system refrigerant explosion suppression scheme.

[0039] Further, the second air port of the shell 1 is provided with an exhaust pipe 13, the exhaust pipe 13 is communicated with the containing cavity through the second air port, and the second air door 3 is located in the exhaust pipe 13 when the second air door 3 is in the second avoiding position.

[0040] In the embodiment of the present application, the outside air enters the containing cavity of the shell 1 through the first air port, the internal pressure of the containing cavity gradually increases, and when reaching a preset value, the gas in the containing cavity pushes the second air door 3 to move to open the second air port. The gas flowing out of the second air port is discharged to the outside through the exhaust pipe 13, the exhaust pipe 13 plays a role of guiding to safely guide the gas to the outside of the vehicle, away from the passenger area, avoids the accumulation in the closed space in the vehicle, reduces the explosion and fire risk, and at the same time guarantees the safety of passengers. When the second air door 3 is in the second avoiding position, the second air door 3 is located in the exhaust pipe 13, which effectively reduces the resistance and leakage probability in the gas discharge process, accelerates the discharge speed of the internal gas, ensures the rapid recovery of the environment in the refrigeration module, and reduces the duration of the increase of the refrigerant concentration.

[0041] As Figure 3As shown, the exhaust pipe 13 includes a first exhaust section 131 and a second exhaust section 132, the first exhaust section 131 is connected with the shell 1, and the second exhaust section 132 is connected with the first exhaust section 131, and the exhaust section of the first exhaust section 131 is larger than that of the second exhaust section 132.

[0042] In the embodiment of the present application, the large-section design of the first exhaust section 131 can provide a large flow area when the gas is initially discharged, which helps to quickly reduce the pressure inside the refrigeration module, thereby accelerating the discharge speed of the internal gas; the exhaust section of the second exhaust section 132 is smaller than that of the first exhaust section 131, so as to increase the flow rate of the gas, so that the gas in the exhaust pipe 13 is quickly diffused to the outside of the vehicle, avoiding excessive local gas concentration, and further reducing the risk of explosion. The first exhaust section 131 with a large section is beneficial to reducing the gas flow rate when the gas is initially discharged, thereby reducing the noise generated in the initial stage of discharge; and the second exhaust section 132 with an elongated shape helps to form a stable gas flow in the later stage of discharge, further suppressing the noise during gas flow discharge, and improving the comfort experience of passengers.

[0043] As shown in Figure 3 , Figure 5 As shown, the exhaust pipe 13 includes a first exhaust section 131 and a second exhaust section 132, the first exhaust section 131 is connected with the shell 1, and the second exhaust section 132 is connected with the first exhaust section 131, and the exhaust section of the first exhaust section 131 is rectangular, and the exhaust section of the second exhaust section 132 is circular, and the exhaust section of the first exhaust section 131 is larger than that of the second exhaust section 132. When the second damper 3 is in the second avoiding position, the second damper 3 is located in the first exhaust section 131.

[0044] Preferably, the first exhaust section 131 is a rigid structure to avoid deformation due to changes in gas pressure, thereby avoiding collision between the second damper 3 and the first exhaust section 131. The second exhaust section 132 is a flexible structure to adapt to the structure of the vehicle body to guide the gas out of the vehicle.

[0045] Further, the explosion suppression device further includes a mounting seat 5, the mounting seat 5 is provided with a through hole 51, and the mounting seat 5 is used for mounting the refrigeration module. The shell 1 includes an upper shell 11 and a lower shell 12. The upper shell 11 is connected with the top of the mounting seat 5, and a first chamber is formed between the upper shell 11 and the mounting seat 5. The lower shell 12 is connected with the bottom of the mounting seat 5, and a second chamber is formed between the lower shell 12 and the mounting seat 5, the second chamber is communicated with the first chamber through the through hole 51, and the second chamber and the first chamber jointly form a containing cavity.

[0046] In the embodiment of the present application, the refrigeration module is connected to the mounting seat 5, and the shell 1 is in a split structure and is arranged on the upper and lower sides of the mounting seat 5, that is, the shell 1 encapsulates the refrigeration module as a cover to achieve a sealing effect. At the same time, the shell 1 is arranged in a split structure to facilitate the installation of the refrigeration module.

[0047] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , the bolt passes through the upper shell 11, the mounting seat 5 and the lower shell 12 in sequence to realize the connection of the upper shell 11, the mounting seat 5 and the lower shell 12. The upper shell 11 abuts against the top surface of the mounting seat 5 through a sealing strip, and the lower shell 12 abuts against the bottom surface of the mounting seat 5 through a sealing strip.

[0048] Further, a first opening is formed in the first side wall of the upper shell 11, and the shell 1 further comprises a first connecting plate 14 which is detachably connected to the upper shell 11. The first connecting plate 14 blocks the first opening, and the first connecting plate 14 is provided with a first mounting hole 141 for mounting a high-low pressure connector of the refrigeration module.

[0049] In the embodiment of the present application, the first connecting plate 14 is detachably connected to the upper shell 11. The high-low pressure connector is first mounted on the first connecting plate 14, and then the first connecting plate 14 is connected to the upper shell 11, which simplifies the assembly process of the refrigeration module and the shell 1, that is, no additional sealing treatment is required when mounting the high-low pressure connector, thereby reducing the assembly difficulty. At the same time, this design enables the entire shell 1 to be unnecessary to be disassembled when the electrical connection part is maintained and inspected, and only the first connecting plate 14 needs to be disassembled, which greatly improves the convenience and efficiency of the later maintenance. Due to the detachability of the first connecting plate 14, when the high-low pressure connector needs to be replaced or upgraded, only the first connecting plate 14 needs to be replaced, thereby avoiding the replacement of the entire shell 1 and effectively controlling the maintenance cost.

[0050] As shown in Figure 3 , the first connecting plate 14 is connected to the upper shell 11 by a bolt, and the first connecting plate 14 abuts against the outer wall of the upper shell 11 through a sealing strip.

[0051] Further, a second opening is formed in the second side wall of the upper shell 11, and the shell 1 further comprises a second connecting plate 15 which is detachably connected to the upper shell 11. The second connecting plate 15 blocks the second opening, and the second connecting plate 15 is provided with a second mounting hole 154 for passing a heat exchanger water pipe of the refrigeration module.

[0052] In the embodiment of the present application, the second connecting plate 15 is detachably connected with the upper shell 11. The water pipe of the heat exchanger is first passed through the second mounting hole 154 on the second connecting plate 15, and then the second connecting plate 15 is connected on the upper shell 11 to block the second opening. Without complex sealing operation in a narrow space, the assembly process is simplified, and the production efficiency is improved. This design facilitates later maintenance. If the water pipe needs to be replaced or the sealing condition needs to be checked, only the second connecting plate 15 needs to be disassembled, without damaging the entire shell 1 structure, thereby reducing the maintenance cost and complexity.

[0053] Specifically, the second connecting plate 15 is a spliced structure, and the second connecting plate 15 includes a plurality of component segments. The plurality of component segments are sequentially distributed along the height direction of the upper shell 11. Each component segment is detachably connected with the upper shell 11. The second mounting hole 154 is formed between the adjacent two component segments.

[0054] In the embodiment of the present application, the second connecting plate 15 is a spliced structure, and the second mounting hole 154 is formed between the adjacent two component segments. That is, the heat exchanger water pipe is wrapped with foam. The heat exchanger water pipe and the component segment of the second connecting plate 15 are connected by buckling to realize the interference fit between the second mounting hole 154 and the heat exchanger water pipe, so that no additional sealing structure is needed between the heat exchanger water pipe and the second mounting hole 154.

[0055] As shown in Figure 3 , Figure 4 The second connecting plate 15 includes a first component segment 151, a second component segment 152, and a third component segment 153.

The upper edge of the first component segment 151 is provided with a semicircular through hole. The lower edge of the second component segment 152 and the upper edge of the second component segment 152 are respectively provided with semicircular through holes.

[0056] Further, the plurality of component segments include the first component segment 151. The first component segment 151 is arranged close to the mounting seat 5. One end of the first component segment 151 close to the mounting seat 5 is provided with a notch 1511. The notch 1511 is used for passing the wire harness of the refrigeration module.

[0057] In the embodiment of the present application, the design of the gap 1511 can first extend the wire harness out of the shell 1, and then install the first component segment 151, that is, the first component segment 151 is clamped with the wire harness through the gap 1511, so as to avoid damage of the wire harness due to friction with the edge of the wire hole. At the same time, the first component segment 151 is clamped with the wire harness through the gap 1511, and a sealing edge is arranged at the edge of the gap 1511, and the sealing edge is in interference abutment with the wire harness to realize sealing, which is simple and reliable in assembly.

[0058] As shown in Figure 4 the gap 1511 is arranged at one end of the first component segment 151 close to the mounting seat 5, and the first component segment 151 and the mounting seat 5 form a wire hole. In order to realize sealed connection of the wire hole and the wire harness, a sealing edge can be arranged at the edge of the wire hole, and the sealing edge is in interference abutment with the wire harness to realize sealing.

The second air port is arranged on the lower shell 12, so as to facilitate discharge of the diluted gas, form an effective air flow circulation, and improve the efficiency and speed of gas dilution.

[0061] As shown in Figure 6 the upper shell 11 is provided with the first air port, the first air door 2 is hinged to the upper shell 11, the first air door 2 has a first blocking position for blocking the first air port, and has a first avoiding position for avoiding the first air port.
