However, when the unit is running at high temperatures, the temperature of the electronic control rises very quickly. The components in the electronic control need to be kept within a suitable temperature range to operate normally. For example: in an extremely high temperature environment of 50-60℃, the internal temperature of the electronic control will be very high when it is running, reaching the device temperature point, causing the device to stop working and affecting the operation of the air conditioner. Different electronic control layouts and heat dissipation forms have different heat dissipation effects on the electronic control.

[0030] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] It should be noted that in this embodiment, the directions or positional relationships indicated by "upper", "lower", "front", "back", etc. are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present application. In addition, "first", "second", "third", and "fourth" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0032] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0033] like Figure 1 As shown, in the present embodiment, an electrically controlled heat dissipation system is provided, which includes a condensing electrically controlled chamber 2 for placing a condenser 1 and an electrically controlled box 3. As the condenser 1 is a common component in the prior art, no further introduction is given here. It is sufficient to ensure that there is a condensing pipe and a condensing fan matched with the condensing pipe inside it, that is, the condenser 1 is equipped with a condensing fan. The present application needs to indirectly borrow the air volume of the condensing fan so that the heat of the condensing electrically controlled chamber 2 can be released.

[0034] Furthermore, the condensing electric control chamber 2 of the present application has an opening on one side, and the opening side faces the windward end of the air conditioning unit, so that the outside fresh air can more easily enter the condensing electric control chamber 2. At the same time, the heat dissipation inlet of the electric control box 3 in the condensing electric control chamber 2 is also arranged facing the opening side of the condensing electric control chamber 2, which also facilitates the outside fresh air entering the condensing electric control chamber 2 to enter the electric control box 3 more easily.

[0035] It should be noted that if it is necessary to keep the fresh air continuously entering the condensing electric control chamber 2 and flowing to the electric control box 3, it is necessary to form a flow channel. Air convection cannot be achieved only through the opening on one side of the condensing electric control chamber 2, and it is also impossible to keep the fresh air from the outside from entering the condensing electric control chamber 2 and flowing to the electric control box 3. Therefore, the present application utilizes the existing condenser 1 and uses the condensing fan as the air outlet component of the condensing electric control chamber 2, so that the air in the condensing electric control chamber 2 can move toward the condenser 1 and be discharged by the condensing fan, so that the condensing electric control chamber 2, the electric control box 3, and the condenser 1 form an air flow channel discharged by the condensing fan. At this time, the fresh air from the outside can flow to the electric control box 3 through the condensing electric control chamber 2, and after completing the heat exchange with the electric control box 3, it is discharged from the heat dissipation outlet of the electric control box 3, and the hot air discharged from the heat dissipation outlet can move toward the condenser 1, so as to use the driving force of the condensing fan to discharge the hot air out of the condenser 1, that is, to discharge the hot air out of the condensing electric control chamber 2.

[0036] At the same time, when the outside fresh air enters the condensing electric control chamber 2, the formed wind path includes not only the flow path formed by the condensing electric control chamber 2, the electric control box 3, the condenser 1, and the condensing fan, but also the flow path directly formed by the condensing electric control chamber 2, the condenser 1, and the condensing fan; in other words, when the outside fresh air enters the condensing electric control chamber 2, a part of the fresh air will flow to the electric control box 3, complete the heat exchange with the electric control box 3, and then be discharged from the condensing electric control chamber 2; the other part will directly reach the condenser 1 position from the condensing electric control chamber 2, thereby completing the heat exchange of the temperature in the condensing electric control chamber 2, and the high-temperature air in the condensing electric control chamber 2 can be discharged from the condenser 1 through the condensing fan; at the same time, another part of the fresh air will flow to the electric control box 3 corresponding to the rear end of the condensing electric control chamber 2 with the inertia of the fresh air, thereby performing heat exchange with the electric control box 3 at the rear end and the condensing electric control chamber 2, and finally being discharged by the condensing fan, thereby realizing the temperature exchange of multiple electric control boxes 3 and the entire condensing electric control chamber 2, so that the high temperature in the condensing electric control chamber 2 will not continue, and the heat inside the electric control box 3 will be released.

[0037] In summary of the above embodiments, in the electronically controlled heat dissipation system provided by the present application, the opening side of the condensing electric control chamber 2 faces the windward end of the air conditioning unit, the condenser 1 and the electric control box 3 are located in the condensing electric control chamber 2, and the heat dissipation inlet of the electric control box 3 faces the opening side, and the heat dissipation outlet of the electric control box 3 discharges air into the condensing electric control chamber 2. The condenser 1 is equipped with a condensing fan, which is used to discharge air from the condensing electric control chamber 2, so that the condensing electric control chamber 2, the electric control box 3, and the condenser 1 form an air flow channel discharged by the condensing fan, ensuring that the outside air can continue to flow through the flow channel, so that the fresh air can continuously and quickly enter the condensing electric control chamber 2, so as to continuously cool the electric control box 3, so that the heat dissipation effect of the electric control box 3 is improved, and at the same time, the condensing electric control chamber 2 will not continue to be high in temperature. In addition, the condensing fan of the condenser 1 is indirectly used as a driving force, and the heat inside the condensing electric control chamber 2 is quickly discharged through the air volume of the condensing fan, so that the heat of the condensing electric control chamber 2 is released. Therefore, the electronically controlled heat dissipation system arranged in the above manner can make full use of the fresh air from the outside, and improve the heat dissipation effect of the electronic control box 3 without affecting the return air from the indoor side, thereby avoiding stopping operation due to excessive temperature of the electronic control components and improving the heat dissipation reliability.

[0038] In this embodiment, the number of condensers 1 is set to two, and there is a certain interval between the two condensers 1. It should be noted that the number of condensers 1 can also be more than two, and there is an interval between two adjacent condensers 1, so that the air in the condensation electric control chamber 2 between the two condensers 1 can flow to the condensers 1 on both sides and finally be discharged through the condensation fan.

[0039] This application takes two condensers 1 as an example for introduction. Figure 1 and Figure 2 It is pointed out above that one side of the condensing electric control chamber 2 is an open side for introducing fresh air from the outside, while the other side is set as a closed side, so that the air in the condensing electric control chamber 2 can flow inside it and be discharged by the condensing fan.

[0040] On this basis, it can be known that the condensation electric control chamber 2 is a cavity structure with an opening on one side and a cavity wall on the other side.

[0041] As for the method of forming the condensing electric control chamber 2, a separate condensing electric control chamber 2 structure can be designed on the lower base shell 11 of the air-conditioning unit, and a separate condensing electric control chamber 2 structure can be formed by cooperating with structures such as the baffle on the lower base shell 11. These will not be described in detail here, and it is sufficient to ensure that the condensing electric control chamber 2 is relatively independent.

[0042] For the dual system, the number of electric control boxes 3 is consistent with the number of condensers 1, both of which are set to two, and multiple electric control boxes 3 are evenly arranged in sequence from the open side to the closed side. In other words, the distribution of the electric control boxes 3 in the condensing electric control chamber 2 is roughly in a row, so that the outside fresh air can enter the front and rear two electric control boxes 3 in sequence; at the same time, the electric control boxes 3 are distributed in a row, and there is no other shielding on both sides of the electric control boxes 3, so that the air can flow directly to the condenser 1 after the heat dissipation outlet is discharged, so as to quickly enter the corresponding condensing fan to discharge the hot air.

[0043] It should be pointed out that the electric control boxes 3 are only roughly distributed in a row, and do not need to be arranged neatly in a straight line. They can also have a certain dislocation effect, so that the outside fresh air that has not entered the front electric control box 3 can more easily enter the rear electric control box 3. No more restrictions are made here. In addition, since the present application utilizes the air volume of the condensing fan, the condensing fan will form a certain degree of negative pressure in the condensing electric control chamber 2, forcing the air in the condensing electric control chamber 2 to flow quickly toward the condensing fan.

[0044] In addition, in this embodiment, the heat dissipation outlet of the electric control box 3 is located at the bottom of the electric control box 3 and the side away from the aforementioned opening side, and there is a certain interval between the bottom of the electric control box 3 and the bottom of the condensing electric control chamber 2, and a first ventilation hole is provided at the position of the bottom of the condensing electric control chamber 2 corresponding to the electric control box 3, so that after the hot air is discharged from the heat dissipation outlet, a part of it enters the rear condensing electric control chamber 2 with the outside fresh air, and the other part is discharged from the condensing electric control chamber 2 through the first ventilation hole, and at the same time, a second ventilation hole is provided at the position of the bottom of the condensing electric control chamber 2 corresponding to the condenser 1, so that the hot air (hot air) of the condensing electric control chamber 2 is discharged through the first ventilation hole, and then flows through the condenser 1 through the second ventilation hole under the action of the condensing fan, and is discharged by the condensing fan. As for the hot air entering the rear condensing electric control chamber 2, its air volume is limited, and it will enter at the same time with the outside fresh air, so within a certain range, it will not affect the temperature of the rear condensing electric control chamber 2 and the heat exchange efficiency of the rear electric control box 3.

[0045] The electric control box 3 may have a plurality of heat dissipation fans 4, which are located at the heat dissipation inlet and can quickly introduce fresh air from the outside into the heat dissipation fins of the electric control box 3, and discharge it from the heat dissipation outlet after the heat dissipation is completed.

[0046] Similarly, for the rear end electric control box 3 and the rear end condensing electric control chamber 2, since there is no other electric control box 3 behind them, the hot air generated by the rear end electric control box 3 will enter the corresponding part of the condenser 1 and will eventually be discharged from the condenser 1.

[0047] Please refer to Figure 3, is a heat dissipation flow path diagram of the heat dissipation system of the present application. It can be seen that the outside fresh air first enters the condensing electric control chamber 2 through the opening side of the condensing electric control chamber 2. Since the condensing electric control chamber 2, the electric control box 3, the condenser 1, and the condensing fan form an air flow path, part of the outside fresh air in the condensing electric control chamber 2 will flow to the electric control box 3, and exchange heat with the heat sink of the electric control box 3, and discharge air from the heat dissipation outlet to the bottom of the condensing electric control chamber 2; and when the hot air encounters the bottom of the condensing electric control chamber 2 and is blocked, the negative pressure generated by the condensing fan will also act on the bottom of the condensing electric control chamber 2, please refer to Figure 2 and Figure 3 , so that the hot air discharged from the heat dissipation outlet flows to the condensers 1 on both sides, and finally, under the action of the condensing fan, is discharged upward outside the condenser 1. In addition, since the bottom of the condensing electric control chamber 2 is provided with a first ventilation hole and a second ventilation hole corresponding to the electric control box 3 and the condenser 1, respectively, under the action of the heat dissipation fan and the condensing fan, the air after heat exchange with the heat sink of the electric control box 3 will be discharged from the condensing electric control chamber 2 through the first ventilation hole, and then flow through the condenser 1 through the second ventilation hole, and discharged by the condensing fan, so that the wind direction circuit is more fully utilized to export heat, and the heat dissipation effect of the electric control is further improved.

[0048] In this embodiment, a partition can be set in the condensing electric control chamber 2 between the condenser 1 and the electric control box 3, and a plurality of through holes 8 for air flow are opened on the partition, so that the hot air in the condensing electric control chamber 2 flows toward the condenser 1 through the through holes 8 and is finally discharged by the condensing fan.

[0049] It should be noted that, since the electric control box 3 of the present application discharges air from the bottom heat dissipation outlet, the through hole 8 can be set at the bottom of the partition as much as possible, so as to correspond to the air outlet position of the electric control box 3, and absorb the hot air discharged from the electric control box 3 in the condensing electric control chamber 2 as quickly as possible.

[0050] In addition, since the number of the electric control boxes 3 of the present application is two, the through holes 8 need to be distributed according to the positions of the two electric control boxes 3, so that the through holes 8 can correspond to at least two electric control boxes 3. It should be noted that since the through holes 8 serve as the middle channel for the condensing electric control chamber 2 to discharge air through the condensing fan, the position of the through holes 8 relative to the condensing electric control chamber 2 is more important; in other words, if the through holes 8 are arranged on both sides of the condensing electric control chamber 2 close to the opening side, the efficiency of the air in the rear part of the condensing electric control chamber 2 reaching the condenser 1 through the through holes 8 will be very low, affecting the heat dissipation efficiency of the rear condensing electric control chamber 2 and the rear electric control box 3. Similarly, if the through holes 8 are arranged on both sides of the condensing electric control chamber 2 close to the closed side, the efficiency of the air in the front part of the condensing electric control chamber 2 reaching the condenser 1 through the through holes 8 will also be very low. Therefore, the present application arranges the through hole 8 on the entire side wall of the partition corresponding to the condensing electric control chamber 2, that is, the through hole 8 is arranged along the opening side of the condensing electric control chamber 2 to the closed side, so that the air in the condensing electric control chamber 2 can reach the condenser 1 through the through hole 8, thereby improving the air flow efficiency, and also improving the heat dissipation efficiency of the condensing electric control chamber 2 and the electric control box 3, and the heat dissipation effect of the electric control box 3 is better.

[0051] The electric control heat dissipation system of the present application can be applied to dual-system electric control heat dissipation. The two electric control boxes 3 are relatively independent and can independently release their internal heat to the outside without affecting each other, or the degree of mutual influence is very small. At the same time, the electric control heat dissipation system can greatly improve the heat exchange efficiency of the condensing electric control chamber 2 and the electric control box 3 under the condition of continuous input of fresh air from the outside, so that the heat of the condensing electric control chamber 2 and the electric control box 3 can be fully released, avoiding continuous high temperature of the electric control box 3 and ensuring its reliable operation.

[0052] In addition, this application also provides an air conditioning unit, please refer to Figure 1 and Figure 2 The air-conditioning unit includes a shell, an electronically controlled heat dissipation system, a compressor cavity 5 and an evaporation cavity 6. The shell serves as the main frame structure of the air-conditioning unit and is used to place various other components constituting the air-conditioning unit. According to actual needs, a corresponding cavity structure can be opened on the lower bottom shell 11 or the upper top cover of the shell to meet the installation requirements of other components.

[0053] The electric control heat dissipation system is any of the above-mentioned electric control heat dissipation systems, and the electric control heat dissipation system includes a condensing electric control chamber 2 for placing a condenser 1 and an electric control box 3. The details are not described here one by one, and the details can be referred to the above-mentioned embodiments. It should be noted that the condensing electric control chamber 2 is located on the windward end side of the shell, and the lower bottom shell 11 and the upper top cover are used together to form the other cavity walls of the condensing electric control chamber 2 except the opening side.

[0054] The compressor chamber 5 and the evaporation chamber 6 are both provided on the shell. A compressor for providing high-pressure and high-temperature refrigerant to the condenser 1 is provided inside the compressor chamber 5. An evaporator for receiving the refrigerant after the heat exchange in the condenser 1 is provided inside the evaporation chamber 6. In addition, an electronic expansion valve is also provided in the evaporation chamber 6. The evaporator supplies cooling air to the air supply area through the evaporation fan used with it. In addition, a return air chamber 7 is also provided on the shell. Through the return air port of the return air chamber 7, the air in the air supply area can flow to the evaporator, and after being cooled by the evaporator, it is sent back to the air supply area. Existing components such as the compressor, evaporator, electronic expansion valve, and evaporation fan will not be described here in detail. For details, please refer to the existing technology to ensure that the refrigeration function of the air-conditioning unit can be achieved in combination with the condenser 1.

[0055] A filter element 9 is arranged at the windward end of the shell and at least covers the corresponding position of the opening side of the condensing electric control chamber. The filter element 9 can be a shutter structure arranged on the end plate of the windward surface structural member, and filter mesh cotton is attached to the shutter, so as to ensure smooth air intake while reducing external wind, sand and other debris from entering the condensing electric control chamber.

[0056] Similarly, an air inlet 10 may also be provided at the windward end of the condenser 1, see Figure 2 , so that the outside fresh air can directly enter the condenser 1, and the heat exchange efficiency of the condenser 1 can be improved, so that the refrigerant can be cooled quickly and the refrigeration effect can be achieved. The filter 9 can also cover the air inlet 10 to prevent debris from entering the condenser 1.

[0057] The present application also provides a vehicle including the above-mentioned air-conditioning unit. Generally speaking, the above-mentioned air-conditioning unit is mostly suitable for passenger cars, but in theory, it can also be applied to other vehicles besides passenger cars, such as trains, trucks and other vehicles with a certain speed and a certain compartment space. The vehicle also includes other necessary components, which will not be repeated here. For details, please refer to the prior art.

[0058] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.
