The phase change radiator is an integrated plate structure with a hollow cavity, and phase change working media are filled in the cavity and are in a negative pressure state. When heat flow is conducted to an evaporation zone of the phase-change radiator from a heat source, the phase-change working medium in the cavity starts to generate a liquid phase vaporization phenomenon at a specific temperature under a vacuum condition, at the moment, the phase-change working medium can absorb heat energy and quickly vaporize, vapor of a vapor phase can fill the whole cavity under the condition, and the vapor phase moves to a condensation section to be cooled and liquefied and then flows back to the evaporation section under the action of gravity or capillary force to form gas-liquid circulation.

The controller is arranged on the compressor side inside the shell or between the heat exchanger side and the compressor side through a middle partition plate. The controller comprises a controller box body, a circuit board and an electrical element; the electrical components comprise heating devices, such as power devices, chips and other heating devices; the heating device is arranged on the circuit board and/or the controller box body.
For the frequency conversion air conditioner, a controller of the frequency conversion air conditioner is widely applied to power modules such as an IGBT (insulated gate bipolar transistor) and the like, and the heat productivity is large. The existing variable frequency controller is usually installed inside the outdoor unit and below the top plate of the casing, and an aluminum profile with fins is used as a radiator. One side of the aluminum profile is a plane and is pasted with heating elements such as power devices or heat conducting plates; the other side is provided with fins to improve the heat dissipation capability. The aluminum profile is arranged in an outdoor unit air duct cavity in front of the heat exchanger as much as possible to realize ventilation. However, due to the limitation of the installation positions of the controller and the radiator, the ventilation and heat dissipation conditions are poor, heat accumulation is caused due to insufficient heat dissipation capacity along with the increase of the heat productivity of the chip and the power module, the temperature rise of the device exceeds the design requirement, and the service life and the reliability of the controller are seriously influenced.

(example 1)
Referring to fig. 1, the phase change heat dissipation control box of the present embodiment includes a control box 1 and a phase change heat sink 2; the phase change radiator 2 is a plate structure which is formed by processing two substrates through a blowing process or a stamping welding process and is internally provided with a fluid channel. Specifically, when the inflation process is adopted for processing, the rolling inhibitor is printed on the substrate, and then the two substrates are riveted and subjected to hot rolling compounding. When in hot rolling, the two substrates are compounded into a whole, but the area printed with the rolling inhibitor in advance is not rolled, so that the area printed with the rolling inhibitor can be blown by high-pressure gas to form a fluid channel. When the stamping and welding process is adopted for processing, the base plates are firstly stamped and formed into the fluid channel, and then the two base plates are welded to form the plate-type structure with the fluid channel arranged inside. And then, filling the plate-type structure with phase-change working media, including but not limited to water, ethanol, R134a, R245fa and R1233zd, and welding and sealing.

When the heat absorption section is in work, the liquid phase-change working medium in the heat absorption section absorbs heat of a heat source and then vaporizes, the gaseous phase-change working medium rapidly expands to fill the whole cavity, the gaseous phase-change working medium is cooled and liquefied after moving to the heat dissipation section, then the liquid phase-change working medium is guided to flow back to the heat absorption section again, and the temperature is lowered in a circulating reciprocating mode.

In order to better adhere to the heat generating element 11, in this embodiment, the upper end surface of the heat absorbing section of the phase change heat sink 2 is a flat surface, and in this case, a certain suppression means may be adopted to control the expansion deformation of the substrate only toward the lower end surface during the inflation. Or when the flow channel is designed, the size of the heating element 11 is considered, so that the area where the heat absorption section of the phase change heat sink 2 is attached to the heating element 11 is a plane, in this scheme, the heating element 11 can be placed in a groove where the attachment area of the heat absorption section 2 is sunken, and the periphery of the heating element 11 is in contact with the fluid channel, so that the heat dissipation effect is better.

The heat dissipation section of the phase change heat sink 2 may be further provided with heat dissipation fins or fin groups to increase the heat dissipation area, which is not shown in fig. 1 to 3, but those skilled in the art can fully know how to implement the phase change heat sink according to the written description.
(example 2)
As shown in fig. 4 to 6, in the present embodiment, the phase change heat sink 2 is extended into the control box 1 from the side of the control box 1. The phase change heat radiator 2 also comprises an upper horizontal section 21, a vertical section 22 and a lower horizontal section 23 in sequence, wherein the upper horizontal section 21 is a heat radiation section, and the lower horizontal section 23 is a heat absorption section. The upper horizontal section 21, the vertical section 22 and the lower horizontal section 23 of the phase change radiator 2 are in arc transition. Specifically, a second through hole is formed in the side surface of the control box 1; and the heat absorption section of the phase change heat radiator 2 passes through a second through hole on the side surface of the control box 1 and is attached to the heating element 11 in the control box 1.

The phase change heat radiator 2 also comprises an upper horizontal section 21, a vertical section 22 and a lower horizontal section 23 in sequence, wherein the upper horizontal section 21 is a heat radiation section, and the lower horizontal section 23 is a heat absorption section. The upper horizontal section 21, the vertical section 22 and the lower horizontal section 23 of the phase change radiator 2 are in arc transition.
The upper end face of the heat absorption section of the phase change radiator 2 is welded with a connecting plate 3; the heating element 11 in the control box 1 is attached to the connecting plate 3. The connecting plate 3 is provided with a groove 31 which can be matched with the heating element 11 in the control box 1; the heating element 11 in the control box 1 is placed in the groove 31. The heating element 11 contacts with the bottom surface and the side wall of the groove 31, the heat dissipation area is increased compared with the situation that only the bottom surface contacts with the connecting plate without the groove, and the heat dissipation effect is further improved.
In order to improve the heat dissipation effect on the basis of example 1. The upper horizontal section 21 of the phase change heat radiator 2 is fixed with a fin group 5.
Of course, the structure of the present embodiment is also applicable to embodiment 2, that is, the phase change heat sink 2 can be inserted into the control box 1 from the side of the control box 1, and the fin group 5 is fixed at the heat dissipation section.
The fin group 5 is preferably fixed to the lower end surface of the heat radiating section.
(example 4)
Referring to fig. 10, the shape of the phase change heat sink 2 in this embodiment is changed from that in embodiments 1 to 3, and the phase change heat sink 2 includes a slope section 24 and a horizontal section 25, where the slope section 24 is a heat dissipation section and the horizontal section 25 is a heat absorption section.
In this embodiment, bend once only to phase change radiator 2, it is more convenient to process.
In the present embodiment, the contact manner between the phase change heat sink 2 and the control box 1 can be changed, that is, the phase change heat sink enters the control box 1 from the side. In the same way, the heat dissipation section of the phase change heat sink 2 can also be provided with heat dissipation fins 4 or fin groups 5; the heat absorbing section of the phase change heat radiator is arranged to be flat (i.e. not blown up here), or the area in contact with the heating element 11 is arranged to be flat (i.e. not blown up here), or a connecting plate is welded on the upper end face of the heat absorbing section. These modifications are based on the idea of the invention and fall into the protection scope of the invention.
Because the integral plate structure of the phase change heat radiator 2 is processed by a blowing process or a stamping welding process, a fluid channel needs to be formed inside the integral plate structure, only one side of the integral plate structure is a plane at most, and the binding surface of the heat absorption section and the heat source, and the composite surface of the heat dissipation section and the fins are on the same side in the embodiment, so that the plane side can be adopted, and the binding and the compounding are more effective.
The above-mentioned embodiments are intended to illustrate the objects, technical solutions and advantages of the present invention in further detail, and it should be understood that the above-mentioned embodiments are only exemplary embodiments of the present invention, and are not intended to limit the present invention, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
