With reference to fig. 1 to 3, an embodiment of the present disclosure provides a heat sink, including a base 10, a fin group 20 and a heat pillar 30, where the fin group 20 includes a plurality of fins stacked parallel to the base 10 and disposed at an interval on one side of the base 10; the heat transfer working medium is filled in the heat column 30 and sequentially penetrates through the base 10 and the fin group 20; wherein, one end of the heat pillar 30 penetrating the susceptor 10 is configured to be embedded in a boss 301 of the susceptor 10, and the diameter of the boss 301 is larger than that of the remaining tube segment of the heat pillar 30.

The heat radiator provided by the embodiment of the disclosure is adopted, heat is transferred to the base 10 and the heat column 30, the heat transfer areas of the heat column 30, the base 10 and the frequency conversion module 40 can be enlarged through the bosses 301, the heat transfer efficiency of the base 10 and the heat column 30 is improved, the heat transfer working medium in the heat column 30 is heated and changes phase, the heat column 30 penetrates through the fins of the fin group 20, the heat transfer efficiency of the fins in the heat column 30 and the fin group 20 is improved, the heat is transferred to the fins in the fin group 20, the heat is radiated and cooled through the fins, the integral temperature uniformity and the heat radiation efficiency of the heat radiator are improved, the efficient heat radiation purpose of the heat radiator on the frequency conversion module 40 under the high-temperature working condition is realized, and the refrigeration effect of the air conditioner under the high-temperature working condition is guaranteed.

The fins of the fin group 20 are stacked at intervals, and the fins are spaced at intervals, so that the fins are beneficial to uniformly stress the rest pipe sections of the heat column 30 after the fin group 20 is sleeved on the heat column 30. Alternatively, the fin group 20 may be a folded fin.

Optionally, the fin group 20 is parallel to the base 10, wherein a fin of the fin group 20 close to the base 10 is in heat conduction connection with the base 10. The fins and the base 10 can be bonded through heat-conducting silica gel, or heat-conducting fins are arranged to improve the heat-conducting efficiency; alternatively, the fins are welded to the base 10. In addition, one fin of the fin group 20 close to the base 10 is detachably connected to the base 10. For example, the fins may be connected to the base 10 by fasteners. Optionally, the fin group 20 is connected to the base 10 by fasteners that extend through the fin group 20. Thus, the stability of the heat sink can be improved.

The heat column 30 is filled with a phase-changeable heat transfer working medium, for example, a liquid heat transfer working medium is heated to change phase into a gaseous heat transfer working medium; the gaseous heat transfer working medium is cooled and becomes a liquid heat transfer working medium. Through the phase change of the heat transfer working medium, the heat generated by the frequency conversion module 40 is transferred to the fin group 20, and the fin group 20 performs air cooling heat dissipation and temperature reduction under the action of air flow.

Optionally, a capillary structure is disposed inside the thermal column 30, and the heat transfer medium is guided by the capillary structure. Therefore, the liquid heat transfer working medium is heated and phase-changed, and is diffused to the low-temperature area along the capillary structure after being changed into the gaseous heat transfer working medium. After the gaseous heat transfer working medium is cooled and changed into the liquid heat transfer working medium, the liquid heat transfer working medium is diffused to the high-temperature area along the capillary structure.

The heat column 30 penetrates the base 10 and the fin group 20, and through holes are formed in both the base 10 and the fin group 20. Wherein, the thermal column 30 and the through hole of the base 10 can be in interference fit. The heat pillar 30 and the base 10 can be fixed relatively by extrusion, so that the adhesion degree and the connection firmness of the heat pillar 30 and the base 10 are improved. Alternatively, the heat slug 30 is clearance fit with the through hole of the susceptor 10. Thus, the through holes between the thermal column 30 and the base 10 can be filled with heat-conducting silica gel or heat-conducting fins, which is helpful for improving the heat-conducting efficiency between the thermal column 30 and the base 10, and further improving the heat-dissipating efficiency of the heat sink.

In addition, the heat column 30 and the through hole of the fin set 20 can be in interference fit. The heat pillars 30 and the fin sets 20 can be fixed relatively by extrusion, so that the fitting degree and the connection firmness of the heat pillars 30 and the fin sets 20 are improved. Alternatively, the heat stake 30 is a clearance fit with the through-holes of the fin pack 20. In this way, the through holes between the thermal column 30 and the fin group 20 can be filled with heat-conducting silica gel or heat-conducting fins, which is helpful for improving the heat-conducting efficiency between the thermal column 30 and the fin group 20, and further improving the heat-dissipating efficiency of the heat sink.

In practical application, run through base 10 and fin group 20 through heat post 30, not only can realize three's mechanical connection, but also can realize the purpose of heat conduction, the heat that frequency conversion module 40 produced is through base 10 and heat post 30, transmits to fin group 20, and fin group 20 realizes the purpose of heat dissipation cooling through the forced air cooling heat dissipation.

The boss 301 constructed at one end of the heat column 30 is embedded in the base 10, on one hand, the connection between the heat column 30 and the base 10 can be realized, and the heat column 30 penetrates through the fin group 20 to be limited, so that the heat column 30 is prevented from sliding out of the fin group 20; on the other hand, when the heat column 30 is thermally connected to the inverter module 40, the boss 301 can increase the contact area between the heat column 30 and the inverter module 40, thereby improving the heat exchange efficiency between the heat sink and the inverter module 40.

The rest tube sections of the heat column 30 penetrate through the fin group 20, and the diameter of the boss 301 is larger than that of the rest tube sections of the heat column 30, so that the heat column 30 can be limited from sliding out of the fin group 20 through the boss 301 under the condition that the heat column 30 penetrates through the fin group 20, and the stability of connection between the heat column 30 and the fin group 20 is improved.

Alternatively, the mesa of the boss 301 is in the same plane as the surface of the base 10. The "surface of the base 10" herein may be understood as a surface of the base 10 contacting the frequency conversion module 40.

The surface of the base 10 and the surface of the boss 301 are located on the same plane, so that the flatness of the contact surface of the heat sink and the frequency conversion module 40 can be ensured, and the fitting degree of the heat sink and the frequency conversion module 40 is further improved, namely the base 10 and the boss 301 of the heat column 30 and the frequency conversion module 40 are fitted. The higher the degree of fitting between the bosses 301 and the susceptor 10 and the inverter module 40, the higher the heat exchange efficiency between the heat column 30 and the susceptor 10 and the inverter module 40.

Optionally, the mesa of the boss 301 is flush with the surface of the base 10. The phrase "the top of the boss 301 is flush with the surface of the base 10" is not only understood to mean that the top of the boss 301 is in the same plane as the surface of the base 10, but also to mean that the top of the boss 301 is parallel to the surface of the base 10, and here, the top of the boss 301 is located in the base 10 and is in a non-contact state with the frequency conversion module 40.

Optionally, a groove is defined by the mesa of the boss 301 and the through hole of the base 10, and the groove may be filled with thermal conductive silica gel. Wherein, the heat-conducting silica gel can fill the whole area of the groove, and even be adhered with the frequency conversion module 40. In this way, not only the firmness of connection between the boss 301 and the base 10 can be improved, but also the heat conduction efficiency between the boss 301 and the base 10 and the frequency conversion module 40 can be improved.

Optionally, a groove defined by the mesa of the boss 301 and the through hole of the base 10 is filled with solder flux for welding the boss 301 and the base 10. Thus, under the condition that the boss 301 is connected with the base 10, the exposed welding part can be avoided, and the integral appearance of the radiator is prevented from being influenced.

Optionally, the thickness of the boss 301 is greater than or equal to the thickness of the susceptor 10.

The top of the boss 301 and the surface of the base 10 are in the same plane, and under the condition that the thickness of the boss 301 is greater than that of the base 10, a certain gap is formed between the base 10 and the fins of the fin group 20, and airflow flows through the gap, so that heat carried by the fins of the base 10 and the fins of the fin group 20 can be blown away, and the purposes of heat dissipation and temperature reduction are achieved.

The mesa of boss 301 and the surface of base 10 are the coplanar, and under the condition that the thickness of boss 301 equals the thickness of base 10, the another face opposite to the mesa in boss 301 laminates with the fin of fin group 20, and base 10 laminates with the fin of fin group 20, like this, can improve the area of contact of base 10 and fin, and then improve the heat transfer efficiency between the two.

In practical application, no matter the thickness of the boss 301 is greater than that of the base 10, or the thickness of the boss 301 is equal to that of the base 10, the effect of improving the heat transfer efficiency of the heat sink can be achieved, and therefore the frequency conversion module 40 can be better cooled.

Alternatively, the heat pillars 30 are vertically disposed on the fin groups 20; alternatively, the heat pillars 30 are obliquely arranged on the fin group 20.

In the case where the heat pillars 30 are vertically provided to the fin group 20, the heat pillars 30 are vertically provided to the base 10. In this way, the processing of the through holes of the base 10 and the fin group 20 is facilitated, and in addition, under the condition that the heat column 30 is horizontally arranged, the fin group 20 and the base 10 are vertically arranged, so that the stability of the fin group 20 and the base 10 can be ensured, and the heat column 30 is prevented from sliding under the action of gravity.

In the case where the heat stake 30 is provided obliquely to the fin group 20, the boss 301 portion of the heat stake 30 may be provided vertically to the susceptor 10, or may be provided obliquely to the susceptor 10. Wherein, in the case that the boss 301 of the heat stake 30 vertically penetrates the susceptor 10, the axis of the boss 301 intersects with the axis of the remaining pipe section of the heat stake 30. In practical applications, the fin group 20 is vertically disposed, regardless of whether the heat pillars 30 are disposed obliquely or vertically disposed on the fin group 20. In addition, the heat pillar 30 is disposed obliquely, and preferably, the boss 301 end of the heat pillar 30 is lower than the other end of the heat pillar 30. Thus, the heat transfer working medium in the thermal column 30 is heated to change phase, and the heat transfer working medium changed into a gaseous state can move upwards along the capillary structure in the thermal column 30; then after heat dissipation and temperature reduction, the heat transfer working medium is condensed into liquid, and can flow downwards to the boss 301 end of the thermal column 30 along the capillary structure in the thermal column 30 under the action of gravity, so that the heat transfer working medium at the boss 301 end can exchange heat with the base 10 and the frequency conversion module 40, and further the heat dissipation efficiency of the frequency conversion module 40 is improved.

Alternatively, the plurality of thermal columns 30 are arranged side by side or offset.

In the case where the plurality of heat columns 30 are arranged side by side, they may be divided into one or more rows, and the plurality of heat columns 30 are regularly distributed. The plurality of heat pillars 30 are uniformly arranged at intervals. In this way, it helps to ensure the strength of the base 10 and the fin group 20. In which the number and the number of rows of the heat pillars 30 can be increased appropriately in a region where heat is high, so that the heat transfer can be accelerated, and the heat dissipation efficiency of the frequency conversion module 40 can be improved.

When the plurality of thermal columns 30 are arranged in a staggered manner, the plurality of thermal columns 30 are arranged in a staggered manner in sequence, or the plurality of thermal columns 30 are arranged in an irregular distribution. Like this, can set up a plurality of heat posts 30 in the high region of heat for thermal transmission realizes rapid cooling to frequency conversion module 40 and handles, prevents that the heat from gathering, leads to the high temperature, damages frequency conversion module 40.

In practical applications, in the case that a plurality of heat columns 30 are arranged side by side and in a plurality of rows, the plurality of rows of heat columns 30 may be arranged in a staggered manner.

Optionally, the heat pillar 30 is detachably connected with the fin group 20; and/or the thermal column 30 is thermally conductively coupled to the base 10.

The rest of the tube sections of the thermal column 30 are detachably connected to the fin group 20, for example, the rest of the tube sections of the thermal column 30 and the fin group 20 may be connected by a snap-fit manner, or the rest of the tube sections of the thermal column 30 and the fins may be bonded by a heat conductive silicone, or the rest of the tube sections of the thermal column 30 and the fin group 20 are connected by a screw thread. This helps to improve the firmness of the connection of the heat stake 30 to the fin set 20.

In addition, the heat column 30 is thermally connected to the fin group 20. Therefore, the heat transfer efficiency between the heat transfer working medium in the heat column 30 and the fin group 20 can be improved, and the fins of the fin group 20 are cooled by air, so that the heat dissipation efficiency of the heat sink is improved.

The bosses 301 of the heat pillars 30 are thermally conductively connected to the susceptor 10. For example, the bosses 301 of the heat slug 30 are in close contact with the susceptor 10. Or the boss 301 of the heat column 30 is welded with the base 10, or the boss 301 of the heat column 30 is bonded with the base 10 through the heat-conducting silica gel, so that the purpose of heat-conducting connection between the heat column 30 and the base 10 can be realized, and the firmness of connection between the heat column 30 and the base 10 can be improved. The bosses 301 of the heat pillars 30 are thermally conductively connected to the susceptor 10. Thus, the heat transfer efficiency of the heat transfer working medium in the base 10 and the heat column 30 can be improved, and the heat dissipation efficiency of the frequency conversion module 40 can be improved.

Optionally, the surface of the base 10 has an area smaller than the area of the fin face of the fin.

Here, the "base 10" has a plate shape and a certain thickness, so that heat transferred from the inverter module 40 can be accumulated. In addition, the "surface of the base 10" herein may be understood as a surface of the base 10 contacting the frequency conversion module 40. The fin surface of the fin is the surface of the fin parallel to the base 10.

The area of the surface of the base 10 is smaller than the area of the fin surface of the fin, so that on one hand, the heat dissipation area of the heat sink can be enlarged through the large-size fin, the base 10 is prevented from being too large in area, the fin is small, and the heat dissipation efficiency is reduced. On the other hand, through the base 10 of smaller size, not only can alleviate the weight of radiator, but also can make the heat of base 10 concentrate more to transmit to heat post 30 fast, make the quick phase transition heat transfer of the heat transfer working medium in the heat post 30, with heat transfer to fin group 20, carry out the forced air cooling heat dissipation, accelerated heat transfer efficiency. In addition to this, a better temperature uniformity can be obtained with a smaller size of the susceptor 10.
