Detailed Description

So that the manner in which the features and elements of the disclosed embodiments can be understood in detail, a more particular description of the disclosed embodiments, briefly summarized above, may be had by reference to the embodiments, some of which are illustrated in the appended drawings. In the following description of the technology, for purposes of explanation, numerous details are set forth in order to provide a thorough understanding of the disclosed embodiments. However, one or more embodiments may be practiced without these details. In other instances, well-known structures and devices may be shown in simplified form in order to simplify the drawing.

An embodiment of the present disclosure provides an air conditioner, as shown in fig. 1, including: a first heat-generating component 10; a fan 81 disposed below the first heat generating member 10; a first heat dissipation member 20 provided in an air outlet path of the fan 81; the first evaporating pipe 30 and the condensing pipe 40 form a closed loop of the heat exchange medium, the first evaporating pipe 30 is connected with the first heat-generating component 10, and the condensing pipe 40 is connected with the first heat-radiating component 20.

Optionally, the fan 81 is arranged to dissipate heat to a heat exchanger in the air conditioner. Therefore, other fans do not need to be additionally arranged, and the fans for dissipating heat of the air conditioner are used for promoting heat dissipation of the heat dissipation components.

A heat exchange medium flows through the first evaporation pipe 30 and the condensation pipe 40, and the heat exchange medium flows in a closed loop formed by the first evaporation pipe 30 and the condensation pipe 40. The heat exchange medium may be a refrigerant, and when the refrigerant flows to the first evaporation tube 30, the refrigerant absorbs heat generated by the first heating part 10 and turns into a gaseous state; when the refrigerant flows to the condensation duct 40, heat is released and the refrigerant becomes liquid. The air conditioner dispels the heat to first heat-generating component 10 through setting up first heat-dissipating part 20, heat transfer that first evaporating pipe 30 and condenser pipe 40 produced first heat-generating component 10 gives first heat-dissipating part 20, first heat-dissipating part 20 is on fan 81's air-out wind path, the wind that can utilize fan 81 to blow off accelerates the heat dissipation, thereby can fully absorb the heat of the heat transfer medium in the condenser pipe 40, be favorable to the heat of the heat transfer medium reabsorption first heat-generating component 10, the reinforcing is to the radiating effect of first heat-generating component 10.

Alternatively, the first heat sink 20 is disposed at an edge of the air outlet path of the fan 81. Thus, influence on air outlet of the air conditioner is avoided.

In some embodiments, the first evaporation pipe 30 and the condensation pipe 40 are disposed along an edge of the air outlet path of the fan 81. Thus, the influence on the air-conditioning outlet air is avoided when the air blown out by the fan 81 is utilized.

Alternatively, the first evaporation pipe 30 is horizontally disposed and the condensation pipe 40 is vertically disposed. Like this, the trend coincidence of first evaporating pipe 30 and condenser pipe 40 and the support that is used for installing fan 81 makes first evaporating pipe 30 and condenser pipe 40 press close to the support setting, can let first evaporating pipe 30 and condenser pipe 40 more firm stable, neither can shelter from the fan 81 air-out like this, can promote the heat dissipation of first heat dissipation part 20 with the help of the wind that fan 81 blew off again, improves heat exchange efficiency.

Alternatively, the first evaporation pipe 30 and the condensation pipe 40 are heat pipes. Thus, when the liquid refrigerant absorbs heat in the first evaporation tube 30 and turns into a gaseous state, a slight pressure difference can be generated in the heat pipe, thereby promoting the refrigerant to flow.

Optionally, the first heat sink 20 is an aluminum heat sink. The heat exchange medium absorbs heat at the first evaporation tube 30, and transfers the heat to the aluminum heat dissipation plate at the condensation tube 40, so that the aluminum heat dissipation plate has a good heat dissipation effect and is not easy to corrode.

Alternatively, the first evaporation tube 30 has a U-shape, wherein the arc side of the U-shape is disposed on the first heat generation part 10. Thus, the heat exchange medium can exchange heat with the first heat generating component 10 when flowing to the arc edge.

Alternatively, the second evaporation tube 60 has a U-shape, wherein the arc sides of the U-shape are disposed on the first heat sink member 20. Thus, the heat exchange medium can exchange heat with the first heat sink 20 when flowing to the arc edge.

In some embodiments, the first evaporation tube 30 includes a capillary section 31, and an entrance end of the capillary section 31 is connected to the condensation tube 40.

The capillary tube section 31 can throttle the heat exchange medium, when the liquid heat exchange medium passes through the capillary tube section 31, part of the heat exchange medium is converted into a gas state to form a gas-liquid mixed heat exchange medium, and the existence of the gas heat exchange medium can improve the overall fluidity of the heat exchange medium; and the gaseous heat exchange medium is difficult to flow back to the condensation section through the capillary section 31, so that the unidirectional flow of the heat exchange medium can be ensured. Thus, the capillary section 31 can enhance the heat exchange effect of the heat exchange medium on the first heat-generating component 10, and improve the heat dissipation effect on the first heat-generating component 10.

Optionally, the number of capillary segments 31 is one or more than one. Therefore, the heat exchange medium can be throttled, the overall fluidity of the heat exchange medium is improved, and the unidirectional flow of the heat exchange medium is ensured.

In some embodiments, more than one capillary segment 31 is connected in parallel. The more than one capillary tube sections 31 are connected in parallel, the heat exchange medium is shunted by each capillary tube after flowing out of the condensation tube 40, and after throttling expansion, the fluidity of the heat exchange medium is enhanced, and the heat dissipation effect on the first heating component 10 is improved.

In some embodiments, the first heat sink 20 includes an inflation plate provided with a refrigerant pipe 21, and the condensation pipe 40 communicates with the refrigerant pipe 21. The heat exchange medium enters the blowing plate from the condensation pipe 40, and is fully released and condensed.

In some embodiments, as shown in fig. 2 and 3, the air conditioner further includes: a second heat-generating component 50; and a second evaporation tube 60 connected to the second heat generating component 50 and connected in parallel to the first evaporation tube 30.

After entering the first evaporation tube 30 from the condensation tube 40, the heat exchange medium is branched at the joint of the second evaporation tube 60 and the first evaporation tube 30, and a part of the heat exchange medium enters the second evaporation tube 60, and absorbs heat generated by the second heat generating component 50 when passing through the second heat generating component 50, thereby dissipating heat from the second heat generating component 50.

In some embodiments, the first heat generating component 10 is a motherboard and the second heat generating component 50 is a reactor. The reactor is a cubic structure with a copper coil embedded in the center of a silicon steel sheet and is an existing product. When the reactor runs, a certain electromagnetic field is arranged below the main board, so that the current inversion link runs more stably and the power factor of the frequency converter is improved.

In some embodiments, the first evaporation tube 30 further includes a first section disposed between the capillary section 31 and the first heat generating component 10, and the second evaporation tube 60 includes a second section communicating with the first section, and an included angle between the second section and the first section is an acute angle.

If the included angle between the first section and the second section is a right angle or an obtuse angle, the heat exchange medium can more easily flow along the first section directly to the first heat generating component 10, and only a small amount of heat enters the second section to dissipate heat from the second heat generating component 50. If the included angle between the first section and the second section is an acute angle, when the heat exchange medium flows to the joint of the first section and the second section, the included angle relative to the first section and the second section is a right angle or an obtuse angle, and the heat exchange medium is easily shunted into the second section, thereby ensuring the heat dissipation of the second heat generating component 50.

In some embodiments, the air conditioner further includes a second heat dissipating part 70, the second heat generating part 50 is disposed inside the second heat dissipating part 70, and the second evaporation tube 60 is connected to the second heat dissipating part 70.

The second heat generating component 50 is disposed inside the second heat dissipating component 70, the second heat dissipating component 70 can absorb heat generated by the second heat generating component 50, and the second evaporation tube 60 absorbs heat absorbed by the second heat dissipating component 70 through the heat exchange medium inside. Thus, the heat dissipation effect of the second heat generating component 50 can be improved in its entirety.

In some embodiments, the second heat sink member 70 includes a housing, the refrigerant pipe 21 is disposed on an inner wall of the housing, and the second evaporation tube 60 is communicated with the refrigerant pipe 21 on the housing. The heat exchange medium flows into the refrigerant pipe 21 through the second evaporation tube 60, and absorbs heat generated from the second heat generating component 50.

Alternatively, the housing of the second heat sink 70 is cube-shaped. When the second heat generating component 50 is a reactor, the reactor generates heat as a whole in an operating state, the shell is cubic, and the refrigerant pipeline 21 is arranged on the inner wall of the shell, so that large-area heat dissipation can be performed on the surface of the reactor, and the heat dissipation effect on the reactor is enhanced.

Optionally, the refrigerant pipes 21 are disposed at the top, bottom and side walls of the housing. Thus, the refrigerant pipe 21 can absorb heat released from each side surface of the second heat generating component 50 over the entire surface, and promote the heat dissipation over the entire surface of the second heat generating component 50.

In some embodiments, as shown in fig. 3, the air conditioner further includes an axial flow fan 80, and a central axis of the axial flow fan 80 is disposed corresponding to the first heat generating component 10. In this way, the airflow generated by the axial fan 80 passes through the first heat generating component 10, and heat dissipation from the first heat generating component 10 is further promoted.

Alternatively, the second heat generating component 50 is disposed below the first heat generating component 10, and the axial flow fan 80 is disposed between the first heat generating component 10 and the second heat generating component 50. The airflow generated by the axial flow fan 80 may pass through the first and second heat-generating components 10 and 50 while enhancing heat dissipation from the first and second heat-generating components 10 and 50.

In some embodiments, the air conditioner further comprises heat dissipation fins 90, and the heat dissipation fins 90 are disposed at one or more of the following locations: a first heat dissipating member 20, a second heat dissipating member 70, a first heat generating member 10, and a second heat generating member 50. The heat radiating fins 90 can enhance the heat radiating effect to the above-described components. When the airflow generated by the axial fan 80 or the blower passes through the heat dissipating fins 90, the heat dissipating effect of the heat dissipating fins 90 can be accelerated.

In some embodiments, the air conditioner further comprises a vacuum chamber vapor chamber 11, wherein the vacuum chamber vapor chamber 11 is disposed at one or more of the following positions: a first heat generating component 10 and a second heat generating component 50. The vapor chamber 11 has a high equivalent thermal conductivity, and can sufficiently absorb the entire amount of heat generated by the first heat generating component 10 or the second heat generating component 50, thereby reducing the temperature of the entire first heat generating component 10 or the second heat generating component 50.

Alternatively, as shown in fig. 4, the vapor chamber 11 of the vacuum chamber includes: a heat absorbing layer 111 and a heat releasing layer 114 stacked; a cavity disposed between the heat absorbing layer 111 and the heat releasing layer 114; an evaporation layer 112 and a capillary channel layer 113 disposed in the cavity, wherein the evaporation layer 112 is disposed adjacent to the heat absorption layer 111. The cavity is filled with refrigerant and vacuum. The heat absorbing layer 111 absorbs heat generated by the heat generating component and transfers the heat to the refrigerant in the evaporation layer 112, and the refrigerant is heated and evaporated in the vacuum-filled cavity, so that latent heat of vaporization promotes heat transfer. The refrigerant vapor rises to contact the capillary tube layer 113, releases heat to the heat release layer 114 and condenses to become liquid, and the liquid refrigerant flows back to the evaporation layer 112 along the capillary tube by liquid tension, thereby completing one cycle.

The heat in the vacuum chamber vapor chamber 11 is transferred from the heat absorbing layer 111 to the heat releasing layer 114 through the evaporation layer 112 and the capillary channel layer 113 in this order, and the heat is transferred from the heat absorbing layer 111 to the heat releasing layer 114 of the vacuum chamber vapor chamber 11. When the vacuum chamber vapor chamber 11 is provided, the heat absorbing layer 111 of the vacuum chamber vapor chamber 11 is provided close to the surface of the first heat generating component 10.

In some embodiments, the first evaporation pipe 30 is connected to the vacuum chamber soaking plate 11 on the first heat-generating component 10. In this way, the first evaporation pipe 30 can absorb the heat released from the vacuum chamber vapor chamber 11 on the first heat generating component 10, thereby promoting the heat dissipation of the vacuum chamber vapor chamber 11 and further enhancing the heat dissipation effect on the first heat generating component 10.

In some embodiments, the second evaporation tube 60 is connected to the vacuum chamber vapor chamber 11 on the second heat generating component 50. Thus, the second evaporation tube 60 can absorb the heat released from the vacuum chamber vapor chamber 11 on the second heat-generating component 50, thereby promoting the heat dissipation of the vacuum chamber vapor chamber 11 and enhancing the heat dissipation effect on the second heat-generating component 50.
