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 provided with a heat pipe 11; a first heat sink member 20 connected to the condensation section of the heat pipe 11; and a refrigerant pipe constituting a closed circuit, including a first heat exchange unit 30 that exchanges heat with the first heat sink 20.

The heat pipe 11 is configured to allow a heat exchange medium, such as a refrigerant, to flow therein, and to absorb heat generated by the first heat generating component 10. The heat pipe 11 is an existing product, and generally includes an evaporation section and a condensation section, where the refrigerant absorbs heat generated by the first heat generating component 10 in the evaporation section to become a gas state, and the refrigerant releases heat to become a liquid state in the condensation section. The first heat dissipation part 20 is connected to the condensation section of the heat pipe 11, so as to absorb heat released from the condensation section of the heat pipe 11, thereby facilitating rapid condensation of the refrigerant at the condensation section. When the refrigerant in the refrigerant pipe flows circularly and flows to the first heat exchange unit 30, the first heat exchange unit 30 exchanges heat with the first heat dissipation part 20, for example, absorbs the heat of the first heat dissipation part 20. Like this, make the heat give first heat dissipation part 20 back through heat pipe 11 transmission by first heat dissipation part 10, the partial heat of first heat dissipation part 20 directly scatters and disappears to the air, partial heat is taken away by the refrigerant pipe, can make first heat dissipation part 20 fully dispel the heat, and then promote the radiating effect to first heat dissipation part 10, and avoided the refrigerant pipe directly to the heat dissipation of first heat dissipation part 10 and the condensation phenomenon that arouses, protect first heat dissipation part 10 safety, avoid burning out first heat dissipation part 10. Because the heat absorption capacity of the refrigerant phase-change heat exchange is large, the temperature of the contact surface of the refrigerant pipe and the first heating component 10 is lower than the dew point temperature of high-temperature air near the first heating component 10, water in the high-temperature air is analyzed and attached to the surface of the low-temperature first heating component 10, condensation occurs on the surface of the first heating component 10, and the first heating component 10 which is running is easily short-circuited and burnt.

Optionally, the first heat exchange unit 30 is adjacent to the first heat sink piece 20. In this way, the heat exchange of the first heat exchange unit 30 with the first heat sink member 20 is facilitated.

Optionally, the first heat exchange unit 30 is in contact with the first heat sink piece 20. Thus, the heat of the first heat sink member 20 is easily transferred to the first heat exchange unit 30.

In some embodiments, a portion of the first heat exchanging unit 30 is disposed inside the first heat sink 20 or in contact with the first heat sink 20, and the first heat exchanging unit 30 includes an extension section 31 extending from the first heat sink 20, and the extension section 31 is disposed near the condensation section of the heat pipe 11.

If a portion of the first heat exchanging unit 30 is disposed inside the first heat dissipating part 20, when the refrigerant flows through the first heat exchanging unit 30, the refrigerant can exchange heat with the inside of the first heat dissipating part 20. If a portion of the first heat exchanging unit 30 contacts the first heat dissipating member 20, the refrigerant exchanges heat with the surface of the first heat dissipating member 20. The protruding section 31 is disposed near the condensation section to absorb a part of the heat of the condensation section in advance, so that the first heat exchange unit 30 and the first heat sink member 20 can sufficiently absorb the heat of the condensation section.

Optionally, part of the first heat exchanging unit 30 is parallel to the first heat sink 20 and the side wall of the first heat exchanging unit 30 abuts against the surface of the first heat sink 20. In this way, the first heat exchange unit 30 can exchange heat with the surface of the first heat sink member 20.

In some embodiments, the first heat exchange unit 30 is a U-shaped pipe section, the arc portion and a part of the vertical portion of the U-shaped pipe section are disposed inside the first heat sink 20, and the other part of the vertical portion is the protruding portion 31. In this way, the refrigerant in the first heat exchange unit 30 can exchange heat with the inside of the first heat sink 20.

Optionally, the condensation section of the heat pipe 11 is parallel to the protruding sections 31 of the U-shaped pipe sections, and the condensation section of the heat pipe 11 is disposed between the protruding sections 31 of the U-shaped pipe sections. Thus, the heat exchange area between the condensation section and the extension section 31 of the heat pipe 11 is increased, which is beneficial to the extension section 31 to absorb the heat of the condensation section of the heat pipe 11.

Optionally, a power device is connected in series with the refrigerant pipe, and the power device is configured to promote the refrigerant to flow in the refrigerant pipe. Thus, the refrigerant can circulate in the closed loop to exchange heat. Optionally, the power plant is a circulation pump. Thus, the refrigerant can circulate in the closed loop.

Optionally, the first heat sink 20 is an aluminum heat sink. The aluminum heat dissipation plate has good heat dissipation effect and is not easy to corrode.

In some embodiments, the protruding section 31 is disposed in parallel with the condensation section of the heat pipe 11, or disposed obliquely with respect to the condensation section of the heat pipe 11. When the protruding section 31 is disposed in parallel with the condensation section of the heat pipe 11, the heat exchange area between the protruding section 31 and the condensation section is large. When the protruding section 31 is disposed obliquely with respect to the condensation section of the heat pipe 11, heat exchange can be performed between the protruding section and the condensation section.

In some embodiments, the refrigerant pipe further includes a transmission section 32 connected to the extension section 31, and the transmission section 32 is parallel to a side of the first heat generating component 10. The transfer section 32 is configured to transfer the refrigerant to the first heat exchange unit 30, and transfer the refrigerant flowing out of the first heat exchange unit 30 to other parts. The transmission section 32 is parallel to the side of the first heat-generating component 10, and when the refrigerant flows to the transmission section 32, the heat remaining on the side of the first heat-generating component 10 can be taken away, so that the first heat-generating component 10 can be subjected to sufficient heat exchange. Thus, the heat pipe 11 and the transfer section 32 can absorb heat generated by the first heat generating component 10 at the same time, and the heat dissipation effect on the first heat generating component 10 is improved.

In some embodiments, as shown in fig. 2, the air conditioner further includes a second heat generating component 40, and the refrigerant pipe further includes a second heat exchanging unit 50 exchanging heat with the second heat generating component 40. The second heat generating component 40 generates heat during operation, and heat dissipation is required, and the second heat exchanging unit 50 can exchange heat with the second heat generating component 40, so as to dissipate heat of the second heat generating component 40. Thus, the air conditioner can simultaneously dissipate heat from the second heat generating component 40.

Optionally, a second heat exchange unit 50 is disposed adjacent to the second heat generating component 40. Thus, the heat generated by the second heat generating component 40 is dissipated in the surrounding air, and when the refrigerant flows through the second heat exchanging unit 50, the heat in the air can be absorbed, so that the heat exchange with the second heat generating component 40 is realized.

In some embodiments, as shown in fig. 2, the heat pipe 11 is disposed on the second heat generating component 40, and the second heat exchanging unit 50 is disposed near the condensation section of the heat pipe 11. The evaporation section of the heat pipe 11 absorbs heat generated from the second heat generating component 40, the condensation section releases heat, and the second heat exchanging unit 50 absorbs heat released from the condensation section. In this way, the second heat exchanging unit 50 indirectly absorbs the heat generated by the second heat generating component 40, and the second heat exchanging unit 50 is prevented from being in contact with or close to the second heat generating component 40 to generate condensation on the surface of the second heat generating component 40, thereby causing damage to the second heat generating component 40.

In some embodiments, as shown in fig. 2, the air conditioner further includes a second heat dissipating part 60 connected to the condensation section of the heat pipe 11 of the second heat generating part 40, and the second heat exchanging unit 50 is disposed on the second heat dissipating part 60. The heat generated by the second heat generating component 40 is transferred to the second heat dissipating component 60 through the heat pipe 11, a part of the heat of the second heat dissipating component 60 is directly dissipated to the air, and the other part of the heat is taken away by the second heat exchanging unit 50, so that the second heat dissipating component 60 fully dissipates the heat, and the heat dissipating effect on the second heat generating component 40 is further improved.

In some embodiments, the second heat exchanging unit 50 is a U-shaped pipe section, the arc portion and a part of the vertical portion of the U-shaped pipe section are disposed inside the second heat sink 60, and the other part of the vertical portion is the protruding portion 31. In this way, the refrigerant in the second heat exchange unit 50 can exchange heat with the inside of the first heat sink 20.

Alternatively, the condensation sections of the heat pipes 11 on the second heat-generating component 40 are parallel to the protruding sections 31 of the U-shaped pipe sections, and the condensation sections of the heat pipes 11 are disposed between the protruding sections 31 of the U-shaped pipe sections. Therefore, the heat exchange area between the condensation section and the extension section 31 of the heat pipe 11 is increased, and the extension section 31 is favorable for absorbing the heat of the condensation section of the heat pipe 11.

In some embodiments, the transfer section 32 is disposed between the protruding section 31 of the first heat exchange unit 30 and the protruding section 31 of the second heat exchange unit 50, parallel to the side of the first heat generating component 10 and disposed near the second heat generating component 40. In this way, the transmission section 32 not only can transmit the refrigerant between the first heat exchange unit 30 and the second heat exchange unit 50, but also can dissipate heat from the side of the first heat generating component 10 and a part of the second heat generating component 40, thereby improving the heat dissipation effect of the air conditioner on the first heat generating component 10 and the second heat generating component 40.

In some embodiments, as shown in fig. 3, the vacuum chamber vapor chamber 70 is provided on the second heat-generating component 40, and the heat pipe 11 is provided on the vacuum chamber vapor chamber 70. The vapor chamber 70 has a high equivalent thermal conductivity, and can sufficiently absorb the heat generated by the entire first heat generating component 10, so that the entire first heat generating component 10 is cooled from the source of the current path, and the heat pipe 11 absorbs the heat generated by the vapor chamber 70, thereby promoting the heat dissipation of the vapor chamber 70. Thus, the heat dissipation effect of the first heat-generating component 10 is further improved.

Alternatively, as shown in fig. 4, the vapor chamber 70 of the vacuum chamber includes: a heat absorbing layer 71 and a heat releasing layer 74 stacked; a cavity disposed between the heat absorbing layer 71 and the heat releasing layer 74; an evaporation layer 72 and a capillary channel layer 73 arranged in the cavity, wherein the evaporation layer 72 is arranged close to the heat absorption layer 71; the cavity is filled with refrigerant and vacuum. The heat in the vacuum chamber vapor chamber 70 is transferred from the heat absorbing layer 71 to the heat releasing layer 74 through the evaporation layer 72 and the capillary channel layer 73 in this order, and the heat is transferred from the heat absorbing layer 71 of the vacuum chamber vapor chamber 70 to the heat releasing layer 74. When the vacuum chamber vapor chamber 70 is provided, the heat absorbing layer 71 of the vacuum chamber vapor chamber 70 is brought close to the surface of the first heat generating component 10.

Alternatively, the refrigerant filled in the vapor chamber 70 is purified water. The pure water is environment-friendly, safe and low-price, and the cavity is filled with vacuum, so that the boiling point of the pure water is reduced, the pure water is easy to be heated and evaporated, and an evaporation condensation phase-change heat exchange process similar to a refrigerant is formed. The heat absorbing layer 71 absorbs heat generated by the heat generating component and transfers the heat to the purified water in the evaporation layer 72, and the purified water is heated and evaporated in the vacuum-filled cavity, so that latent heat of vaporization promotes heat transfer. The purified water vapor rises to contact the capillary tube layer 73, condenses and releases heat to the heat release layer 74, and simultaneously liquid water flows back to the evaporation layer 72 along the capillary tube by liquid tension, thereby completing one cycle.

In some embodiments, as shown in fig. 3, the vacuum chamber vapor chamber 70 is provided on the first heat-generating component 10, and the heat pipe 11 is provided on the vacuum chamber vapor chamber 70. The heat pipe 11 absorbs the heat of the vacuum chamber vapor chamber 70, and promotes the heat dissipation of the vacuum chamber vapor chamber 70. Thus, the heat dissipation effect of the first heat-generating component 10 is further improved.

In some embodiments, as shown in fig. 3, the air conditioner further includes heat dissipation fins 80, and the heat dissipation fins 80 are disposed at one or more of the following locations: a first heat dissipating member 20, a second heat dissipating member 60, a first heat generating member 10, and a second heat generating member 40. The heat radiating fins 80 can enhance the heat radiating effect to the components.

In some embodiments, the first heat generating component 10 is a motherboard and the second heat generating component 40 is a reactor. Set up heat pipe 11 heat dissipation on mainboard and the reactor, heat dissipation part carries out the heat transfer with heat pipe 11, makes the condensation section of heat pipe 11 fully condense, and the refrigerant pipe in time dispels the heat to heat dissipation part through heat transfer unit, is favorable to the abundant heat dissipation to mainboard and reactor, and has avoided the refrigerant pipe directly to the mainboard and the reactor heat dissipation and the condensation phenomenon that arouses.
