An electronic control unit 100 according to an embodiment of the first aspect of the present utility model is described below with reference to the accompanying drawings.

An electronic control unit 100 according to an embodiment of the present utility model includes: the electric control box 10, the circuit assembly 20 and the fireproof piece 30 are formed on the electric control box 10, the circuit assembly 20 comprises a circuit board 24 and a first heating device 21 arranged on the circuit board 24, the first heating device 21 is an inductive device 210 and comprises a base part 211 and a magnetic ring part 212, the inductive device 210 penetrates through the electric control box 10 through the first opening 10a, so that the base part 211 is positioned in the electric control box 10, the magnetic ring part 212 is positioned outside the electric control box 10, and the base part 211 is in sealing fit with the electric control box 10, so that the first opening 10a is closed. The fireproof member 30 is disposed outside the electronic control box 10 and covers the magnetic ring portion 212.

It should be noted that, the application scenario of the electronic control unit 100 of the present utility model is not limited, for example, the electronic control unit 100 may be used to control the actions of components such as a compressor, an electromagnetic valve, a fan, etc.

For example, when the working environment in which the electronic control unit 100 is applied is complex, such as when contaminants such as oil dirt, dust, etc. are present in the air of the working environment. In the embodiment of the utility model, the first opening 10a is formed on the electronic control box 10, the base portion 211 is located inside the closed electronic control box 10, and the base portion 211 is in sealing fit with the electronic control box 10, so that the internal space of the electronic control box 10 is formed into a closed space, and adverse effects on components including the base portion 211 inside the electronic control box 10 caused by the entry of pollutants such as greasy dirt and dust into the electronic control box 10 are avoided.

By arranging the fireproof piece 30, the fireproof piece 30 covers the magnetic ring part 212, the fireproof effect can be achieved, and the use safety of the magnetic ring part 212 can be improved. Optionally, the fireproof member 30 may also have functions of flame retarding and insulation, and the magnetic ring portion 212 is disposed inside, so as to further improve the use safety and working stability of the magnetic ring portion 212.

Moreover, considering that the heat dissipation efficiency of the closed environment in the electronic control box 10 is low, the heat accumulation of the internal environment of the electronic control box 10 is aggravated, so that the embodiment of the utility model extends the magnetic ring portion 212 of the inductive device 210 out of the electronic control box 10 from the first opening 10a, thereby avoiding the temperature rise of the magnetic ring portion 212 on the electronic control box 10 and reducing the adverse thermal influence of the heat of the magnetic ring portion 212 on the components in the electronic control box 10. On the other hand, the magnetic ring portion 212 is arranged outside the electric control box 10, so that the thermal influence of heat in the electric control box 10 on the magnetic ring portion 212 can be reduced, and the magnetic ring portion 212 is arranged between the fireproof piece 30 and the electric control box 10, and the electric control box 10 is not blocked by sealing, so that the heat dissipation efficiency of the magnetic ring portion 212 is improved. Compared with the arrangement of the magnetic ring portion 212 inside the electronic control box 10, the temperature inside the electronic control box 10 can be effectively reduced, adverse thermal influence of the magnetic ring portion 212 on components inside the electronic control box 10 is improved, and the working stability and the use safety of the electronic control component 100 are improved.

In addition, the height of the inductive device 210 is relatively high, and in particular, the height dimension of the magnetic ring portion 212 is larger than the height dimension of the base portion 211, so that by extending the magnetic ring portion 212 from the first opening 10a into the electronic control box 10, the height of the electronic control box 10 can be lower than the height of the inductive device 210, without setting the overall height of the electronic control box 10 to be higher than the height dimension of the inductive device 210, the material of the electronic control box 10 can be saved, and the manufacturing cost can be reduced.

For example, the inductive device 210 may be an inductive device with relatively high heat generation in the inductive device, such as PFC inductor (where PFC is Power Factor Correction abbreviated as power factor correction) or common mode inductor connected to strong electricity. For example, the heat dissipation performance of the whole electric control component 100 can be improved, so that the heat dissipation problem of a high-power (for example, the cooling capacity is greater than 3500W) sealed electric control box can be solved, and the high-frequency PFC inductor can be on board.

Illustratively, the electric control component 100 is applied to a kitchen air conditioner, the indoor heat exchange portion and the outdoor heat exchange portion of the kitchen air conditioner are integrally arranged and are arranged above the kitchen ceiling, the electric control component 100 is internally integrated with the control component of the indoor heat exchange portion and the control component of the outdoor heat exchange portion, so that the electric power of the components inside the electric control component 100 is higher, the heating value is larger, and the electric control box 10 needs to be constructed into a sealing structure based on the special use environment of the electric control component 100 so as to avoid damage to the electric control component 100 caused by greasy dirt, water vapor and the like, and the sealing structure and the kitchen environment both can lead to higher working temperature inside the electric control box 10, so that the components inside the electric control box 10 are more difficult to dissipate heat. The magnetic ring part 212 of the inductive device 210 extends out of the electric control box 10, so that the temperature inside the electric control box 10 can be effectively reduced, the heat dissipation efficiency of the inductive device 210 with larger heat productivity is improved, and the working stability and the use safety of the electric control component 100 are improved.

According to the electric control component 100 of the embodiment of the utility model, the electric control box 10 is set as the sealing element, and the fireproof element 30 is in sealing fit with the electric control box 10, so that oil stains are prevented from contacting elements including the inductive device 210 in the electric control box 10, the working stability of the electric control component 100 is improved, and the service life of the electric control component 100 is prolonged. And the magnetic ring part 212 of the inductive device 210 extends out of the electric control box 10, so that the temperature inside the electric control box 10 can be effectively reduced, adverse thermal influence of the magnetic ring part 212 on other elements inside the electric control box 10 is avoided, and the heat dissipation efficiency of the inductive device 210 can be improved, so that the working stability and the use safety of the electric control component 100 are improved.

As shown in fig. 1 and 2, according to some embodiments of the present utility model, the fireproof member 30 is disposed outside the electronic control box 10 and the fireproof member 30 is in sealing engagement with the electronic control box 10, so that the magnetic ring portion 212 is located in the closed space formed between the fireproof member 30 and the electronic control box 10. The magnetic ring part 212 is arranged in the closed space formed between the fireproof piece 30 and the electric control box 10, so that the heat influence of heat in the electric control box 10 on the magnetic ring part 212 can be reduced, the magnetic ring part 212 can radiate heat to the fireproof piece 30, and the heat radiation efficiency of the magnetic ring part 212 is improved.

The fireproof piece 30 and the electric control box 10 together form another closed space, and the magnetic ring portion 212 of the inductive device 210 is arranged in the closed space formed between the fireproof piece 30 and the electric control box 10, so that the magnetic ring portion 212 of the inductive device 210 can be closed and protected, and pollutants such as oil stains and dust can be prevented from entering the closed space between the fireproof piece 30 and the electric control box 10 to adversely affect the magnetic ring portion 212. Therefore, in general, the oil stain is prevented from contacting the components and parts in the electronic control box 10, the inductive device 210 and the like, so that the working reliability of the circuit assembly 20 can be further improved, the working stability of the electronic control part 100 is improved, and the service life of the electronic control part 100 is prolonged.

Further, by disposing the magnetic ring portion 212 in the closed space formed between the fireproof member 30 and the electronic control box 10, the fireproof effect of the fireproof member 30 can be enhanced, and the use safety of the magnetic ring portion 212 can be enhanced. Optionally, the fireproof member 30 may also have functions of flame retarding and insulating, etc., to isolate the magnetic ring portion 212 inside, thereby further improving the use safety and working stability of the magnetic ring portion 212.

As shown in fig. 4, according to other embodiments of the present utility model, the fireproof member 30 is covered on the magnetic ring portion 212, and a heat dissipation opening 31 for dissipating heat is formed on at least one wall surface of the fireproof member 30. The air flow outside the electric control box 10 can directly exchange heat with the magnetic ring part 212 through the heat dissipation through hole 31, so that the heat dissipation efficiency of the magnetic ring part 212 is improved.

Optionally, the surface of the magnetic ring portion 212 may be treated, for example, a coating is covered on the surface of the magnetic ring portion 212, so that the heat dissipation efficiency of the magnetic ring portion 212 is improved, and meanwhile, the oil dirt in the air is prevented from directly contacting the magnetic ring portion 212, so that the working stability of the magnetic ring portion 212 is improved. For example, the surface of the magnetic ring portion 212 may be covered with an insulating coating to improve safety.

As shown in fig. 1 and 2, according to some embodiments of the present utility model, the electronic control box 10 includes an inner shell 11 and an outer shell 12 covering the inner shell 11, a first opening 10a penetrates the inner shell 11 and the outer shell 12, the inner shell 11 is a flame-retardant insulating shell and is in sealing engagement with the base portion 211, and the outer shell 12 is a flame-retardant heat-conductive shell and is in sealing engagement with the flame-retardant member 30.

The first opening 10a penetrates the inner and outer cases 11 and 12, and may be that the first opening 10a includes a first sub-opening formed on the inner case 11 and a second sub-opening formed on the outer case 12, the first and second sub-openings being aligned in opening direction and covering the first sub-opening, and the inductive device 210 may sequentially pass through the first and second sub-openings without being interfered.

The inner case 11 is in sealing engagement with the base portion 211 so that the inner space of the electronic control box 10 is formed as a closed space, and the outer case 12 is in sealing engagement with the fireproof member 30 so as to form a closed space between the fireproof member 30 and the electronic control box 10.

It should be noted that "closed" as used herein is understood in a broad sense, and may be an absolute closed or a substantially closed, and may be understood as a closed as long as the air flow passage (such as a heat dissipation hole) for heat dissipation is not provided.

The electric control box 10 has a double-layer structure, so that the structural reliability of the electric control box 10 can be improved. The outer shell 12 is a fireproof heat-conducting shell, so that the fireproof performance of the electric control box 10 can be ensured, the heat dissipation efficiency of the electric control box 10 is improved, and the temperature inside the electric control box 10 can be effectively reduced. The inner shell 11 is a flame-retardant insulating shell, which is favorable for improving the flame retardance and fire resistance of the electric control box 10 and ensures the use safety of the electric control box 10.

In some embodiments of the present utility model, the outer shell 12 is a metal shell and the inner shell 11 is a plastic shell. The metal shell can guarantee the structural reliability and the fire resistance of the electric control box 10, and the insulating shell can be used for playing roles in insulation and the like, and the plastic shell has a flame retardant effect besides the insulating effect, so that the flame retardant fire resistance of the electric control box 10 is improved. Furthermore, the manufacturing cost of the electronic control box 10 can be reduced.

As shown in fig. 1, according to a first embodiment of the present utility model, the fireproof member 30 is a metal member and is spaced from the magnetic ring portion 212.

The fireproof part 30 is a metal part, so that the structural reliability and the fireproof performance can be improved, the heat conduction performance of the metal part is better, the heat dissipation of the magnetic ring part 212 between the fireproof part 30 and the electric control box 10 is facilitated, and the heat dissipation efficiency of the inductive device 210 is improved. The metal member has conductivity, so that the fireproof member 30 and the magnetic ring portion 212 are arranged at intervals, current can be prevented from forming between the fireproof member and the magnetic ring portion, and the use safety of the electric control component 100 is ensured.

In some embodiments, the fire protection member 30 is a metal member and is spaced from the magnetic ring portion 212 by a distance of 5mm-10mm. When the distance between the magnetic ring portion 212 and the fireproof member 30 is too large, the heat radiation and heat dissipation efficiency of the magnetic ring portion 212 to the fireproof member 30 is low, and the heat dissipation capacity of the magnetic ring portion 212 is insufficient; while too small a spacing between the magnetic ring portion 212 and the fireproof member 30 does not satisfy the electrical safety distance. By setting the distance between the magnetic ring portion 212 and the fireproof member 30 to the above-described distance value, the safety requirements can be satisfied while improving the heat radiation efficiency.

In some embodiments, the fireproof member 30 is a metal member, and the structural shape of the fireproof member 30 may be selected according to actual use.

Illustratively, the cross-sectional shape of the flame retardant member 30 is rectangular in the thickness direction of the circuit board 24, and the flame retardant member 30 is formed of mutually perpendicular plates, which facilitates the design and processing of the flame retardant member 30 and also facilitates the sealing connection of the outer shell 12 with the flame retardant member 30.

Illustratively, also for example, since the magnetic ring portion 212 is circular, the cross-sectional shape of the fireproof member 30 may be set to be circular, so that the shapes of the magnetic ring portion 212 and the fireproof member 30 are matched with each other, so that the intervals between the respective portions of the magnetic ring portion 212 and the fireproof member 30 are uniform, and the heat radiation and heat dissipation efficiency of the magnetic ring portion 212 is improved.

According to a first embodiment of the present utility model, a fire protection member 30 is assembled and connected with the outer shell 12. For example, the fire protection member 30 is assembled and connected to the outer shell 12 by welding, bonding, or fastening, etc. in a separate manufacturing.

As shown in fig. 2, according to a second embodiment of the present utility model, the fireproof member 30 is made of heat-conductive silica gel and is formed on the magnetic ring portion 212.

The heat conducting silica gel has better heat conducting performance, can improve the heat radiating efficiency of the magnetic ring part 212, has insulativity and can improve the safety. Therefore, the heat-conducting silica gel can be directly connected with the magnetic ring part 212 and is covered on the magnetic ring part 212, so that the contact area between the heat-conducting silica gel and the magnetic ring part 212 can be increased, the heat dissipation efficiency can be improved, the size and the height of the fireproof piece 30 can be reduced, the occupation of the electric control part 100 to the external space can be reduced, and the arrangement of the electric control part 100 is facilitated.

And the heat conduction silica gel is formed on the magnetic ring part 212, and the heat conduction silica gel and the magnetic ring part 212 are integrally arranged and are mounted on the circuit board 24, so that the setting difficulty of the heat conduction silica gel can be simplified, and the assembly efficiency is improved. Of course, the present utility model is not limited thereto, and in other embodiments, for example, the thermally conductive silica gel may be molded alone and then fixed on the electronic control box 10, or integrated with the electronic control box 10 directly, or the like.

Optionally, a thermally conductive silicone is injection molded over the magnetic ring portion 212.

In some embodiments, the fire protection member 30 is a thermally conductive silicone and the cross-sectional area of the side of the thermally conductive silicone away from the circuit board 24 is smaller than the cross-sectional area of the side near the circuit board 24. It can be appreciated that the magnetic ring portion 212 is circular, so that the cross-street area of the magnetic ring portion 212 gradually decreases in a direction away from the circuit board 24, and the heat-conducting silica gel is set to be in a shape matching with the magnetic ring portion 212, so that the distance between the magnetic ring portion 212 and the outer edge of the heat-conducting silica gel is in a preset range, and the heat dissipation efficiency of the magnetic ring portion 212 can be further improved.

As shown in fig. 1 and 2, according to some embodiments of the present utility model, the circuit assembly 20 further includes a second heat generating device 22 disposed on the circuit board 24, the second heat generating device 22 is disposed in the enclosed electronic control box 10, the electronic control box 10 includes an inner shell 11 and an outer shell 12 covering the outer shell 11, the inner shell 11 is a flame-retardant insulating shell and is formed with a second opening 112, the outer shell 12 is a flame-retardant heat conducting shell and covers and seals the second opening 112, and an end of the second heat generating device 22 remote from the circuit board 24 corresponds to the second opening 112.

The second heating device 22 is located in the closed electric control box 10, so that the pollution of oil stains, dust and other pollutants can be prevented from contacting the second heating device 22, and the working reliability of the second heating device 22 is improved. However, considering that the electronic control box 10 is a completely sealed environment, the heat of the second heat generating device 22 is not easy to dissipate, so the second opening 112 is provided in the inner shell 11 of the second heat generating device 22 in a direction away from the circuit board 24, and the second heat generating device 22 can rapidly radiate heat to the outer shell 12 through the second opening 112, so as to improve the heat dissipation efficiency of the second heat generating device 22.

Illustratively, the outer shell 12 is a fireproof heat-conducting shell with relatively high heat conductivity, the inner shell 11 is a flame-retardant insulating shell with relatively low heat conductivity compared with the outer shell 12, and the outer shell 12 is located outside the inner shell 11, and the outer shell 12 can directly contact the external space. Therefore, the second opening 112 is disposed at the opposite position of the inner shell 11 and the second heat generating device 22, so that the second heat generating device 22 directly radiates heat to the outer shell 12 through the second opening 112, which is beneficial to heat radiation of the second heat generating device 22 to the electronic control box 10, and improves heat radiation efficiency of the second heat generating device 22. The utility model can prevent pollutants such as greasy dirt, dust and the like from contacting elements in the electric control box 10, reduce the temperature in the electric control box 10 and improve the heat dissipation efficiency of the second heating device 22. Moreover, the design of the electric control box 10 is beneficial to reducing the cost.

In some embodiments, the distance between the end of the second heat generating device 22 far away from the circuit board 24 and the electronic control box 10 may be 5mm-10mm, so that the safety requirement can be met while the heat radiation efficiency is improved, and the safety is improved.

By way of example, the second heat generating device 22 may include an inductive device (e.g., PFC inductor or common mode inductor coupled to a strong current, etc.) that generates a relatively high level of heat, and/or a capacitive device (e.g., high voltage capacitor, etc.).

As shown in fig. 1 and 2, according to some embodiments of the present utility model, the circuit assembly 20 further includes a third heat generating device 23 disposed on the circuit board 24, the third heat generating device 23 is disposed in the enclosed electronic control box 10, the electronic control unit 100 further includes a heat dissipating component 40 disposed through the electronic control box 10, and a portion of the heat dissipating component 40 is disposed in the electronic control box 10 and is in heat transfer with the third heat generating device 23, and a portion of the heat dissipating component 40 is disposed outside the electronic control box 10 to dissipate heat outside the electronic control box 10.
