The heating and ventilation device can be an air conditioner, a multi-split air conditioner, a heat pump device, a swimming pool machine, a water heater and the like, and the embodiment of the application is not particularly limited.

Fig. 1 is a schematic view of an internal structure of a heating and ventilation device provided in an embodiment of the present application, fig. 2 is a schematic view of a structure of an electronic control box provided in an embodiment of the present application, and fig. 3 is a partial view of a position a in fig. 2.

Referring to fig. 1 to 3, the heating and ventilation apparatus of the present application includes an apparatus main body 200 and an electronic control box 100, and the apparatus main body 200 may include a case 210 and a middle barrier 220 disposed in the case 210. The middle partition plate 220 divides the interior of the box 210 into a fan cavity 211 and a compressor cavity 212, and the electric control box 100 is arranged at the middle partition plate 220, so that the electric control box 100 is positioned at the separation position of the fan cavity 211 and the compressor cavity 212, and the electric control box 100 is installed in the box 210, so that the control of heating and ventilation equipment is realized through the electric control box 100.

Wherein, automatically controlled box 100 can include casing 110 and control circuit board 120, and casing 110 encloses to establish and forms inclosed holding chamber, and control circuit board 120 sets up in holding the intracavity to ensure automatically controlled box 100 has good sealing performance, makes automatically controlled box 100 can realize waterproof, dirt-proof effect, and control circuit board 120 has dry clean operational environment, and then has good job stabilization nature and longer life. In addition, when the cooling medium leaks from the heating and ventilation device, the airtight electric control box 100 can prevent the cooling medium from entering the electric control box 100, so as to avoid the risk of burning or explosion.

In some embodiments, a fan 230 is disposed in the fan cavity 211, a side of the housing 110 facing the fan cavity 211 has a plurality of heat dissipation portions 113, the plurality of heat dissipation portions 113 are arranged at intervals, and a heat dissipation channel 1131 is formed between adjacent heat dissipation portions 113, and the heat dissipation channel 1131 faces the fan 230, so that an air flow formed by the fan 230 passes through the heat dissipation channel 1131, and when the air flow passes through the heat dissipation channel 1131, heat on the heat dissipation portions 113 can be taken away.

It can be appreciated that, because the accommodating cavity is a closed space, the heat of the control circuit board 120 can be transferred to the housing 110, and the heat dissipation portion 113 can be used as a part of the housing 110 extending outwards, that is, the heat of the housing 110 can be transferred to the heat dissipation portion 113, so that the air flow generated by the fan 230 in the fan cavity 211 is used for performing heat exchange with the heat dissipation portion 113, thereby realizing air cooling heat dissipation of the heat dissipation portion 113, and further, the heat of the housing 110 can be continuously taken away by the heat dissipation portion 113, and the heat on the control circuit board 120 can be continuously taken away by the housing 110, so that the heat dissipation and cooling of the control circuit board 120 can be performed, thereby improving the thermal management efficiency of the electronic control box 100, ensuring that the control circuit board 120 and the electronic control box 100 have better heat dissipation performance, and that the control circuit board 120 has a proper temperature environment during operation.

It should be noted that, in the embodiment of the present application, the heat generated by the control circuit board 120 inside the electronic control box 100 during operation is transferred to the housing 110 through the heat conduction mode, and the housing 110 takes away the heat by the air flow in the fan cavity 211 through the heat dissipation portion 113 to realize heat dissipation, so that the heat dissipation process does not need to pass through the compressor cavity 212, the heat dissipation path is shortened, and the heat dissipation efficiency is improved.

Referring to fig. 1, the length direction of the heating and ventilation device is defined as the X direction, the width direction of the heating and ventilation device is defined as the Y direction, and the height direction of the heating and ventilation device is defined as the Z direction, wherein the plate surface of the middle partition 220 may be perpendicular to the bottom wall of the box 210, and the plate surface of the middle partition 220 is parallel to the YZ plane, so that the inner space of the box 210 is divided into the fan chamber 211 and the compressor chamber 212 arranged in parallel through the middle partition 220 in the length direction (X direction) along the device main body 200.

The fan 230 of the apparatus body 200 may be installed in the fan chamber 211, and the compressor 240, the pipeline, and other structures of the apparatus body 200 may be installed in the compressor chamber 212. The apparatus body 200 may be understood as other structures than the electronic control box 100 in the heat pump arrangement. That is, the apparatus body 200 may include, but is not limited to, a case 210, a blower fan 230, a compressor 240, and the like. The structure of the apparatus body 200 is not further limited in this application.

In fig. 1, only the mounting position of the electronic control box 100 in the case 210 of the apparatus main body 200 is shown, and the structure of the apparatus main body 200 is shown as a schematic structure, and thus fig. 1 does not limit the structures of the apparatus main body 200 and the heating and ventilation apparatus.

The specific structure of the heat dissipation portion 113 and the layout of the heat dissipation channels 1131 will be described in detail.

With continued reference to fig. 1 to 3, in one possible implementation, the extending direction of the heat dissipation channel 1131 may be consistent with the flowing direction of the airflow formed by the fan 230, when the heating ventilation device is operated, the blades of the fan 230 rotate to generate a wind field, and the airflow in the wind field may smoothly flow into the heat dissipation channel 1131 when passing through the outer wall of the housing 110.

It will be appreciated that, in the fan cavity 211, the fan 230 is located at a side of the electronic control box 100, the rotation axis of the fan 230 blade may be parallel to the middle partition 220, the rotation axis of the fan 230 blade extends along the Y direction, the heat dissipation portion 113 is located at a side of the tangential direction of the rotation diameter profile of the fan 230, and the shape of the heat dissipation channel 1131 may be matched with the wind field in the fan cavity 211, so that the air flow may smoothly enter the heat dissipation channel 1131.

In some embodiments, the heat dissipation portion 113 may protrude from the outer wall of the housing 110, and the heat dissipation portion 113 may have an included angle with the outer wall of the housing 110, so that the heat dissipation portion 113 and the air flow in the fan cavity 211 may have a sufficient contact area to improve the heat dissipation effect.

It is understood that the included angle of the heat dissipation portion 113 relative to the outer wall of the housing 110 may be any angle ranging from 0 ° to 90 °, including, but not limited to, 10 °, 30 °, 60 °, 90 °, etc., and the specific included angle of the heat dissipation portion 113 relative to the outer wall of the housing 110 may be vertical and oriented according to the flow path of the air flow of the blower 230 passing through the outside of the electronic control box 100, which is not specifically limited in this embodiment of the present application.

For example, the heat dissipation portion 113 may be perpendicular to the outer wall of the housing 110, that is, the included angle between the heat dissipation portion 113 and the outer wall of the housing 110 is 90 °, so that the heat dissipation portion 113 is extended and extended outwards as a heat dissipation structure of the housing 110, which may further increase the effective heat dissipation area of the heat dissipation portion 113 and improve the heat dissipation effect.

It should be noted that, the number of the heat dissipation portions 113 may be set according to the distance between the adjacent heat dissipation portions 113, the plurality of heat dissipation channels 1131 are formed by the plurality of heat dissipation portions 113 together, the plurality of heat dissipation portions 113 may be disposed in parallel and equidistantly spaced, and the area covered by the plurality of heat dissipation portions 113 may be matched with the surface profile of the side of the housing 110 facing the fan cavity 211.

Referring to fig. 1 to 3, in one possible implementation manner, the heat dissipation portion 113 may be a heat dissipation fin, and the heat dissipation portion 113 and the housing 110 may be an integral part, so that the distribution density of the heat dissipation portion 113 may be increased, the heat dissipation effect may be improved, meanwhile, the processing convenience may be improved, and the production cost may be reduced.

It can be appreciated that the integrally formed heat dissipation portion 113 and the housing 110 may be made of metal, so as to increase the heat dissipation area of the housing 110, so that the entire housing 110 forms a heat dissipation structure, and heat dissipation uniformity is enhanced, and meanwhile, heat of the control circuit board 120 can be transferred to the heat dissipation portion 113 outside the housing 110 as soon as possible by utilizing the heat conducting property of metal, so that heat dissipation of the control circuit board 120 is further accelerated, and heat management efficiency of the electronic control box 100 and heat dissipation properties of the control circuit board 120 and the control box are improved.

The housing 110 may be an aluminum housing, for example. Alternatively, the housing body 111 may be made of a heat conductive metal having a good heat conductive property, such as an aluminum alloy or copper. In the embodiment of the present application, the preparation materials of the case 110 and the heat dissipating part 113 are not further limited.

Fig. 8 is a schematic structural diagram of an electronic control box according to an embodiment of the present application, and fig. 9 is a partial view of a position B in fig. 8.

Referring to fig. 8 and 9, in some embodiments, the heat dissipation fin may include a fin body 1132 and at least one thickening portion 1133 integrally connected, the fin body 1132 is connected to the housing, the plurality of thickening portions 1133 in the same heat dissipation fin may be disposed at intervals along the length direction of the fin body 1132, and the thickening portions 1133 have end surfaces parallel to the housing, so that the structural strength of the heat dissipation fin can be enhanced through the disposition of the plurality of thickening portions 1133.

Because the thickened portion 1133 has an end surface parallel to the shell 110, in the manufacturing process, the thimble facing the thickened portion 1133 in the injection mold can abut against the end surface of the thickened portion 1133, so that the thimble and the radiating fin have more contact area on the end surface of the thickened portion 1133, and the shell 110 can be conveniently separated from the injection mold.

The positions of the thickened portions 1133 on the adjacent radiating fins along the length direction of the fin body 1132 are staggered, so that the thickened portions 1133 on the adjacent radiating fins can be arranged in a staggered manner along the length direction of the fin body 1132, and the space between the adjacent radiating fins can be reduced while the arrangement of the thickened portions 1133 on the fin body 1132 is realized, and the occupied area of the radiating portions 113 on the shell 110 is reduced.

Illustratively, the thickness of the thickened portion 1133 may be 1.1-3.5 times the thickness of the fin body 1132, including but not limited to 1.1 times, 1.2 times, 2 times, 3 times, 3.4 times, 3.5 times, etc., as the embodiments of the present application are not specifically limited thereto.

For example, the distance between two adjacent thickened portions 1133 in the same fin may be 0.2 to 0.6 times the length of the fin, including but not limited to 0.2 times, 0.3 times, 0.4 times, 0.5 times, 0.6 times, etc., which is not particularly limited in the embodiment of the present application.

In some embodiments, the heat dissipating portion 113 may include at least two extension sections connected in sequence, different extension sections having different extension directions, wherein the extension direction of the extension section opposite to the air inlet end of the heat dissipating channel 1131 coincides with the air flow direction of the blower 230.

It can be understood that, by arranging the plurality of extension sections, on one hand, when the airflow field of the fan 230 turns, the airflow still can smoothly enter the heat dissipation air duct, so as to reduce the impact between the airflow and the heat dissipation portion 113, and make the heat dissipation portion 113 play a role in guiding the airflow as much as possible, so as to ensure good circulation efficiency and heat dissipation effect. On the other hand, the plurality of extension sections are sequentially connected and matched, so that the circulation path of the air flow in the heat dissipation channel 1131 can be prolonged, the heat dissipation effect is improved, and the smoothness of the heat dissipation air flow entering the heat dissipation channel 1131 is ensured.

For example, the profile shape of the heat dissipating portion 113 formed by splicing the plurality of extension segments may be matched to the wind field shape of the fan 230, for example, the heat dissipating portion 113 may have a "T" shape, or the heat dissipating portion 113 may have an arc shape, including but not limited to a circular arc shape, a parabolic shape, etc., which is not specifically limited in the embodiment of the present application.

In addition, in order to increase the flow rate of the air flow in the heat dissipation channel 1131, the thickness dimension of the end, connected to the housing 110, of the heat dissipation portion 113 may be greater than the thickness dimension of the end, facing away from the housing 110, of the heat dissipation portion 113, so that in the direction in which the air flow flows along the heat dissipation channel 1131, the heat dissipation channel 1131 may be narrowed, the flow rate of the air flow is increased, and the heat exchange efficiency is improved.

In some embodiments, at least a portion of the heat dissipating parts 113 may be disposed in a vertical direction, i.e., the heat dissipating parts 113 may extend in a Z direction in fig. 1, and a spacing between adjacent heat dissipating parts 113 may be controlled by a thickness of the heat dissipating parts 113, i.e., a width of the heat dissipating channels 1131 may be controlled by a thickness of the heat dissipating parts 113.

It will be appreciated that as the heat dissipating portions 113 are thicker, the smaller the spacing between adjacent heat dissipating portions 113, the smaller the width of the corresponding heat dissipating channel 1131. And when the heat dissipation portions 113 are thinner, the spacing between the adjacent heat dissipation portions 113 is larger, and the width of the corresponding heat dissipation channel 1131 is larger.

For example, the thickness dimension of the end of the heat dissipation portion 113 connected to the housing 110 may be greater than or equal to 1.6mm, and the air flow of the fan 230 flows into the heat dissipation channel 1131 from the bottom end of the heat dissipation portion 113, and the distance between the heat dissipation portion 113 and the end near the housing 110 may be 1.6mm-5mm, including but not limited to 1.6mm, 1.7mm, 1.8mm, 1.9mm, 2mm, 2.5mm, 3mm, 5mm, etc., which is not limited in this embodiment of the present application.

Illustratively, the thickness dimension of the end of the heat dissipating portion 113 facing away from the housing 110 may be 1.5mm or more, and the thickness of the top end of the heat dissipating portion 113 may be 1.5mm-5mm, including but not limited to 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, 2mm, 2.5mm, 3mm, 5mm, etc., which are not particularly limited in this embodiment. The heat dissipation portion 113 is only required to have a trapezoidal or trapezoid-like cross section, and the heat dissipation channel is required to have an inverted trapezoid cross section, so that good heat dissipation efficiency can be ensured under the condition of maintaining a high airflow velocity.

The structure of the housing 110 and the way of dissipating heat of the control circuit board 120 in the accommodating chamber will be described in detail.
