Referring to fig. 1 to 6, an outdoor unit of an air conditioner according to an embodiment of the present disclosure includes an electrical control box 10, a heat sink 20, and an edge bracket 30, where the electrical control box 10 is transversely disposed in the outdoor unit of the air conditioner and is used for installing a frequency conversion module 101; the radiator 20 is arranged on the electronic control box 10 and is in heat conduction connection with the frequency conversion module 101; the edge bracket 30 is arranged at the bottom of the electric control box 10 to support the radiator 20; wherein, the edge support 30 is obliquely arranged, or a part of the edge support 30 is in an oblique structure, so that the radiator 20 is inclined to accelerate the heat transfer medium circulation flow in the radiator 20.

By adopting the outdoor unit of the air conditioner provided by the embodiment of the disclosure, the heat generated by the frequency conversion module 101 is transferred to the radiator 20, the heat transfer medium in the radiator 20 is heated and changes phase to a gaseous heat transfer medium, and the radiator 20 is obliquely arranged under the condition that the electric control box 10 is transversely arranged through the edge support 30, so that the gaseous heat transfer medium moves along the oblique direction and can carry away the heat from the area corresponding to the frequency conversion module 101 at any time, thereby reducing the temperature of the area corresponding to the frequency conversion module 101 in the radiator 20; gaseous heat transfer medium becomes liquid heat transfer medium after the cooling to under the action of gravity rapid reflux to the region that corresponds frequency conversion module 101 in radiator 20, in order to carry out next heat dissipation circulation, so, accelerated the circulation flow rate of heat transfer medium in radiator 20, promoted the radiating effect to frequency conversion module 101.

The radiator 20 is arranged in the electronic control box 10, is connected with the frequency conversion module 101 in a heat conduction mode, is lapped on the edge support 30, and is detachably connected with the edge support 30. The edge support 30 and the bottom of the electronic control box 10 can ensure the connection stability of the radiator 20 and the electronic control box 10 in the assembling, transporting and using processes, and avoid collision and unnecessary damage. In addition, the radiator 20 is detachably connected with the edge bracket 30, and the radiator 20 and the edge bracket 30 can be ensured to be synchronously and obliquely arranged so as to prevent the radiator 20 from sliding downwards from the edge bracket 30 under the action of gravity.

The edge bracket 30 may be disposed along a circumferential direction of the heat sink 20 to support the heat sink 20. Alternatively, the edge brackets 30 are symmetrically disposed at both sides of the heat sink 20 to support the heat sink 20. In the case that the edge brackets 30 are obliquely disposed, at least the edge brackets 30 disposed at symmetrical both sides of the heat sink 20 are obliquely disposed to ensure that the heat sink 20 is obliquely disposed.

Part of the edge support 30 is an inclined structure, and it can be understood that, in the case where the edge support 30 is disposed along the circumferential direction of the heat sink 20, at least the edge supports 30 disposed at both symmetrical sides of the heat sink 20 are inclined, so that the heat sink 20 is inclined.

In the case where the radiator 20 is disposed obliquely, the relatively low end may be understood as an evaporation end of the radiator 20, and the relatively high end may be understood as a condensation end of the radiator 20.

The frequency conversion module 101 is preferentially connected with the evaporation end of the heat sink 20 in a heat conducting manner. The liquid heat transfer medium in the heat sink 20 is stored at the evaporation end under the influence of gravity. The heat generated by the frequency conversion module 101 is transferred to the evaporation end of the heat sink 20, the heat transfer medium at the evaporation end is heated to change phase into gaseous heat transfer medium, the gaseous heat transfer medium moves upwards along the inclined direction to the condensation end of the heat sink 20, the gaseous heat transfer medium is rapidly carried away by the heat at the evaporation end, and is subjected to heat dissipation and condensation at the condensation end to become liquid heat transfer medium, and the liquid heat transfer medium rapidly flows back to the evaporation end under the action of temperature difference, pressure difference and gravity to perform the next heat dissipation cycle.

In addition, through the liquid heat transfer medium of microthermal, not only reduced the temperature of radiator 20 evaporating end, moreover based on the difference in temperature of frequency conversion module 101 and radiator 20 evaporating end, can accelerate the heat transfer efficiency between frequency conversion module 101 and the evaporating end to the heat dissipation cooling effect to frequency conversion module 101 has been promoted.

Alternatively, the inverter module 101 and the heat sink 20 may be connected by a fastener, or may be bonded to the heat sink 20 by a thermally conductive silicone adhesive, or may be welded to the heat sink 20. Optionally, a heat conducting fin may be further disposed between the frequency conversion module 101 and the heat sink 20 to improve the heat transfer efficiency between the frequency conversion module 101 and the heat sink 20, so as to improve the heat dissipation and cooling effects on the frequency conversion module 101.

Optionally, the bottom of the electronic control box 10 is configured with a hollow portion 102, and the heat sink 20 is inserted through the hollow portion 102, so that part of the heat sink 20 is exposed to the external environment; the hollow portion 102 is located on a side of the electronic control box 10 close to the fan, so that the airflow generated by the fan acts on the heat sink 20 exposed to the external environment, thereby increasing the heat dissipation efficiency of the heat sink 20.

The frequency conversion module 101 is located in the electronic control box 10, and heat generated by the frequency conversion module is transferred to the radiator 20 and the air in the electronic control box 10, so that the temperature of the air in the electronic control box 10 is increased, and the temperature of the frequency conversion module 101 is not reduced, and the work of the frequency conversion module 101 is influenced.

Radiator 20 wears to locate the fretwork portion 102 of automatically controlled box 10 bottom, and like this, part radiator 20 is located automatically controlled box 10, and the heat of receiving rather than the frequency conversion module 101 transmission of heat conduction connection, the part exposes in automatically controlled box 10 outsidely, carry out the heat exchange with the outer ambient air of automatically controlled box 10, make radiator 20 transmit the heat that frequency conversion module 101 produced to the external environment of automatically controlled box 10 from the internal environment of automatically controlled box 10, not only can carry out the heat dissipation cooling to frequency conversion module 101, and reduced the inside ambient temperature of automatically controlled box 10, further promoted the cooling effect to frequency conversion module 101.

In addition, the hollow part 102 is located on one side of the electronic control box 10 close to the fan, so that the airflow generated by the fan flows through the exposed part of the radiator 20 to perform air cooling enhanced heat dissipation on the radiator 20, and the heat is blown away from the radiator 20, thereby improving the heat dissipation efficiency of the radiator 20.

Alternatively, in the case where the radiator 20 is disposed obliquely, the exposed radiator 20 is disposed obliquely toward the direction of the fan, so that the radiator 20 is disposed obliquely upward toward the fan. In this way, the airflow from the fan can act on more areas of the heat sink 20, and the heat dissipation efficiency of the heat sink 20 is further improved.

Optionally, the edge support 30 is disposed along the circumference of the hollow portion 102 to avoid interference with the portion of the heat sink 20 passing through the hollow portion 102.

Edge support 30 sets up along the circumference of fretwork portion 102, and edge support 30 is located the edge of fretwork portion 102 to guarantee the assembly stability between edge support 30 and automatically controlled box 10. In this way, it is not only satisfied that the heat sink 20 penetrates the hollow portion 102 and does not interfere with the heat sink 20, but also that the edge support 30 can support the heat sink 20.

In the case where the rim support 30 is of a unitary construction, the heat sink 20 is disposed not only through the hollow portion 102, but also through a hollow portion defined around the rim support 30.

Optionally, a waterproof gasket is disposed between the edge bracket 30 and the edge of the hollow portion 102, and/or between the edge bracket 30 and the heat sink 20, so as to prevent moisture in the outside air from entering the electronic control box 10 from the hollow portion 102.

The edge support 30 is located at the edge of the hollow-out portion 102, and the waterproof sealing gasket is arranged between the edge support 30 and the edge of the hollow-out portion 102, so that water vapor in the outside air can be prevented from entering the electric control box 10 from a contact gap between the water vapor and the hollow-out portion, and the electronic elements such as the frequency conversion module 101 in the electric control box 10 are prevented from being corroded, and therefore the service life of the outdoor unit of the air conditioner is influenced.

The waterproof sealing gasket is arranged between the edge support 30 and the radiator 20, so that water vapor in the external air can be prevented from entering the electronic control box 10 from a contact gap between the edge support 30 and the radiator to cause corrosion of electronic elements such as the frequency conversion module 101 in the electronic control box 10, and the service life of the outdoor unit of the air conditioner is influenced.

Optionally, the heat sink 20 comprises: the base 201 is in heat conduction connection with the frequency conversion module 101 and is used for receiving heat generated by the frequency conversion module 101; the blowing plate 202 is in heat conduction connection with the base 201, and heat transfer media capable of changing phases are filled in the blowing plate; the fin group 203 is in heat conduction connection with the inflation plate 202; the heat transfer medium in the blowing plate 202 receives the heat transferred from the base 201, and transfers the heat to the fin group 203 for heat dissipation and temperature reduction.

The base 201 is connected with the frequency conversion module 101 in the electric control box 10 in a heat conduction mode, namely, the frequency conversion module 101 is arranged on the surface of the base 201. The heat generated from the inverter module 101 is transferred to the base 201, the base 201 has a certain thickness, and the base 201 continuously accumulates the heat from the inverter module 101 and continuously transfers the heat to the blowing plate 202. The heat transfer medium in the blowing plate 202 is heated to change phase and transfer heat to the fin group 203 for heat dissipation and temperature reduction.

Wherein the relatively lower end of the blowing plate 202 is an evaporation end and the relatively higher end is a condensation end. Alternatively, in the case where the size of the base 201 is smaller than that of the inflation plate 202, the base 201 is thermally connected to the evaporation end of the inflation plate 202.

In addition, in the case where the size of the base 201 is smaller than that of the blowing plate 202, the blowing plate 202 is detachably connected to the edge bracket 30. In this way, the base 201 is located above the blowing plate 202 and is directly assembled on the blowing plate 202 under the action of gravity, so that the stress on the base 201 is reduced, the deformation of the base 201 is reduced, and the heat transfer efficiency between the base 201 and the frequency conversion module 101 is ensured; but also ensures a stable connection of the heat sink 20 with the edge bracket 30.

In the case where the size of the base 201 is greater than or equal to the size of the inflation plate 202, it is possible to determine that the edge support 30 is detachably connected to the base 201 or the inflation plate 202 according to actual conditions. No matter the edge support 30 is detachably connected with the base 201 or the edge support 30 is detachably connected with the inflation plate 202, the fin group 203 of the heat sink 20 is exposed outside the electronic control box 10.

The interior of the blowing plate 202 is configured with flow channels which are communicated with each other and filled with a heat transfer medium which can change phase. The heat transfer medium is phase-transformed in the blown sheet 202. The heat transfer medium at the evaporation end of the expansion plate 202 receives the heat transferred by the base 201, is heated to change phase, is changed into gaseous heat transfer medium, moves towards the condensation end, is condensed at the condensation end to be cooled, is changed into liquid heat transfer medium, and flows back to the evaporation end under the action of temperature difference, pressure difference and gravity to perform the next heat dissipation cycle.

The fin group 203 is in heat conduction connection with the surface of the blowing plate 202 and is exposed outside the electronic control box 10, the heat of the blowing plate 202 is transferred to the fin group 203, and the heat exchange area with the surrounding air is enlarged through a plurality of fins of the fin group 203, so that the heat dissipation efficiency of the heat sink 20 is improved.

Alternatively, the heat transfer medium may be a phase-changeable medium such as water, a refrigerant, or the like.

Optionally, the base 201 comprises: a first surface 2011 in thermally conductive connection with the frequency conversion module 101; a second surface 2012 disposed opposite the first surface 2011 and in thermally conductive communication with the inflation plate 202; the first surface 2011 has a planar structure or a stepped structure.

The heat generated by the frequency conversion module 101 is transferred from the first surface 2011 to the second surface 2012 of the base 201, then transferred to the blowing plate 202, and transferred to the fin group 203 through the blowing plate 202 for heat dissipation and temperature reduction.

The base 201 has a certain thickness and can store heat. In the case of the first surface 2011 having a stepped structure, the base 201 includes a high step portion 2013 and a low step portion 2014, wherein the high step portion 2013 has a thickness greater than that of the low step portion 2014. In this way, the inverter module 101 is preferentially installed in the high step part 2013. Thus, the base 201 can receive more heat from the frequency conversion module 101, and the heat dissipation and cooling effects on the frequency conversion module 101 can be improved.

In addition, the high step 2013 of the base 201 is in thermal conductive connection with the evaporation end of the inflation plate 202. In this way, the heat accumulated in the high-step portion 2013 is transferred to the evaporation end of the inflation plate 202, and is heated and phase-changed by the liquid heat transfer medium in the evaporation end to be changed into the gaseous heat transfer medium, so that the heat is taken away from the evaporation end, the heat of the base 201 is rapidly reduced, and the heat dissipation and cooling efficiency of the frequency conversion module 101 is accelerated.

Optionally, the inflation plate 202 comprises: a heat absorbing surface in heat conducting connection with the base 201; and the heat dissipation surface is in heat conduction connection with the fin group 203.

The heat absorbing surface of the blowing plate 202 is in heat conduction connection with the base 201, the heat radiating surface is in heat conduction connection with the fin group 203, and heat transferred by the base 201 is transferred to the fin group 203 by heat transfer media in the blowing plate 202 for heat radiation and temperature reduction. The phase change of the heat transfer medium has high heat transfer efficiency, so that the heat transfer efficiency between the base 201 and the blowing plate 202 and between the blowing plate 202 and the fin group 203 can be improved through the phase change of the heat transfer medium in the blowing plate 202, thereby improving the heat dissipation and cooling effects on the frequency conversion module 101.

The fins of the fin group 203 are perpendicular and attached to the blowing plate 202. Alternatively, the fin set 203 may be folded fins or the fins may take the form of clips. Thus, the contact area between the fin group 203 and the heat radiation surface of the inflation plate 202 can be increased, and the heat transfer efficiency of both can be further improved.

Alternatively, the inflation plate 202 has a plate structure, and in the case that the first surface 2011 of the base 201 has a planar structure, the plate surface area of the inflation plate 202 is larger than the surface area of the second surface 2012 of the base 201.

In the case where the first surface 2011 of the base 201 is a planar structure, the base 201 is a plate-like structure in which both the first surface 2011 and the second surface 2012 are planar. The plate surface area of the expansion plate 202 is larger than the surface area of the second surface 2012 of the base 201, and it can be seen that the size of the expansion plate 202 is larger than the size of the base 201. Based on this, the base 201 and the variable frequency module 101 are disposed at the evaporation end of the blowing plate 202, so as to improve the heat dissipation efficiency of the variable frequency module 101.

Alternatively, in the case where the plate surface area of the inflation plate 202 is larger than the surface area of the second surface 2012 of the base 201, part of the frequency conversion module 101 is provided to the inflation plate 202, and the heat generated by the frequency conversion module 101 is transferred to the inflation plate 202.

Most of the frequency conversion modules 101 are arranged on the base 201 based on the size of the base 201, the frequency conversion modules 101 cannot be gathered and arranged, and different heat generation amounts of different frequency conversion modules 101 are different, and the heat is transferred to the inflation plate 202 through the base 201. However, a small part of the frequency conversion module 101 is directly arranged on the blowing plate 202, and the generated heat is directly transferred to the blowing plate 202 for heat dissipation. In this way, the base 201 stores more heat generated by the inverter module 101 thermally connected thereto, and the heat dissipation effect of the inverter module 101 corresponding to the base 201 is improved.

In addition, a part of the frequency conversion module 101 is disposed on the inflation plate 202, and the heat is directly transferred to the heat transfer medium of the inflation plate 202, which is helpful to ensure the heat transfer efficiency and the temperature uniformity of the whole heat sink 20.

Optionally, the expansion plate 202 is provided with mounting holes 204 to allow the inverter module 101 to be inserted into the expansion plate 202.

The frequency conversion module 101 is inserted into the mounting hole 204 of the inflation plate 202 through a fastener, so as to improve the connection firmness between the frequency conversion module 101 and the inflation plate 202. The fastener is a metal piece and can also play a role in transferring heat.

A specific example of the connection between the frequency conversion module 101 and the expansion plate 202 is given below, in which a nut is embedded in the mounting hole 204 of the expansion plate 202, and the frequency conversion module 101 is fixedly connected with a stud or bolt. Thus, the inverter module 101 can be screwed into the nut in the mounting hole 204 by means of a stud or a bolt.
