[0003] Application No. 201220026396.3 discloses a CPU heat exchanger. The CPU heat exchanger comprises a plurality of equally spaced arc-shaped heat exchange fins and a riveted structure. The arc-shaped heat exchange fins are arranged at the outwardly extending heat exchange portions at both ends of the arc-shaped heat exchange fins, and are located between the arc-shaped heat exchange fins. The riveted structures are arranged between two adjacent arc-shaped heat exchange fins, with one riveted structure positioned above and one below the outwardly extending heat exchange portion. These structures support and secure the equally spaced arc-shaped heat exchange fins, preventing them from deforming irregularly due to external forces, which could lead to uneven spacing between the fins and affect the heat exchange efficiency of the CPU heat exchanger.

[0004] There are many heat-generating components on a computer, the main ones being the components that carry a heavy load during operation, such as the processor, memory, storage, network card, etc.

[0005] Currently, the most common heat exchange methods for heating elements are air cooling and water cooling. Water cooling is expensive and has the risk of water leakage. Air cooling absorbs the heat from the heating element through the tower heat exchange fins and dissipates the heat into the air with the help of a fan. Although the tower heat exchange fin structure has been improved and the fan technology has been improved, the air cooling heat exchange is still limited in its cooling effect. Therefore, even with the improved tower heat exchange fin structure and fan, this air cooling heat exchange has limited cooling effect on the heating element. Therefore, the heat exchange capacity of the tower heat exchanger is greater than the air cooling requirement of the heating element, which results in two situations:

[0006] First, the tower heat exchanger is improved but is subject to the limitations of air-cooled heat exchange. Air-cooled heat exchange requires heat absorption and heat exchange through copper tubes and fins, which has low efficiency and slow heat exchange. Therefore, even if the tower heat exchanger is improved, the improvement in the cooling effect of the heating element is very limited;

[0007] Second, the tower heat exchanger has been improved to enhance its heat transfer capacity, but the performance of the tower heat exchanger cannot be fully utilized for heat transfer of heating elements;

[0008] In order to further reduce the temperature of the internal components of the calculator and to fully utilize the heat transfer performance of the tower heat exchanger, we provide a heat-absorbing heat exchange device with a collection of heating elements. Summary of the Invention

[0009] In response to the above-mentioned problems existing in the prior art, the present invention provides a heat absorption and heat exchange device with a collection of heating elements, thereby fully utilizing the heat exchange performance of the heat exchanger and reducing the surface temperature of other components in the chassis, thereby further reducing the temperature inside the chassis.

[0011] Preferably, the heat absorbing portion of the heating element is bonded to the surface of the heating element by means of a heat-conducting adhesive, and grooves are provided on the outer side walls of the heat absorbing portion of the heating element.

[0012] Preferably, the inner side of the second cavity has a filling mechanism, and the filling mechanism includes an airbag.

The end of the air inlet and exhaust pipe is connected to the outer wall of the heat absorbing part of the heating element, and a sealing ring is provided between the outer side of the air inlet and exhaust pipe and the inner wall of the heat absorbing part of the heating element to increase the sealing performance.

[0013] Preferably, the intake and exhaust pipes are provided with corrugated folds, and the corrugated folds facilitate the expansion and contraction of the intake and exhaust pipes.

[0014] Preferably, at least one conical telescopic portion is installed on the inner wall of the intake and exhaust pipes, and the conical telescopic portion is in a truncated cone shape.

[0015] Preferably, a plurality of auxiliary airbags are distributed inside the second cavity, adjacent auxiliary airbags are connected to each other and the auxiliary airbags at the ends are connected to the airbag, and the auxiliary airbags are distributed at corresponding positions of the groove.

[0016] Preferably, a sealing sheet is integrally connected to the inner wall of the port of the intake and exhaust pipes. Four fan-shaped sealing sheets form a circle, and adjacent side walls are in contact with each other. The sealing sheet uses its own elastic tension to flatten on the inner wall of the intake and exhaust pipes to increase the sealing of the intake and exhaust pipes.

[0017] Preferably, the heat conducting pipe is composed of a copper pipe and a soft telescopic pipe, and the soft telescopic pipe can be easily adapted to the heating elements in different positions.

[0020] The working principle and advantages of the present invention are:

[0021] 1. By connecting several collective heat absorption mechanisms on the heat absorption cover of the heating element, the collective heat absorption mechanism transfers the heat of the heating device inside the chassis to the heat absorption cover of the heating element, and the heat is exchanged through the heat-conducting copper tube and heat exchange fins through the heat absorption cover of the heating element, making full use of the heat exchange performance of the heat exchanger, while reducing the surface temperature of other components in the chassis, which can further reduce the temperature inside the chassis.

[0023] 3. When the computer is turned off or the load of related components is reduced and the temperature drops, the thermal fluid gradually liquefies. At the same time, the volume of the thermal fluid decreases, and the airbag returns to its original shape under the action of its own elastic force. Air needs to be inhaled during the recovery process. During the air intake process, the tapered telescopic part and the through hole increase the air intake speed. The speed is increased and the pressure is reduced. By lowering the temperature, the airbag and the heat absorption part of the heating element can be further cooled, which helps to improve the heat exchange effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following is a further detailed description through specific implementation methods:

[0033] like Figures 1 to 7As shown, a heating element collective heat absorption and heat exchange device includes a heating element heat absorption cover plate 1 in contact with the heating element, the heating element heat absorption cover plate 1 is connected to the heat-conducting copper tube 3 by welding, and a plurality of heat exchange fins 2 for increasing the heat exchange area are distributed on the outside of the heat-conducting copper tube 3. It also includes a collective heat absorption mechanism 4 connected to the heating element heat absorption cover plate 1, the collective heat absorption mechanism 4 is connected to the heating element in the computer to absorb heat and transfer heat to the heating element heat absorption cover plate 1, the collective heat absorption mechanism 4 includes a connecting plate 401, a heat-conducting tube 402 and a heating element heat absorption part 403, the connecting plate 401 is fixed to the heating element heat absorption part 403 through the heat-conducting tube 402, the heating element heat absorption part 403 is connected to the heating element in the computer, and a cavity 1 4011 and a cavity 2 4031 are respectively opened on the inner sides of the connecting plate 401 and the heating element heat absorption part 403, and the cavity 1 4011 and the cavity 2 4031 are connected. The heat conducting pipe 402 is connected, and the inner sides of cavity one 4011, heat conducting pipe 402 and cavity two 4031 are all filled with heat conducting liquid 406 for absorbing heat. Space needs to be reserved for vaporization of heat conducting liquid 406. Conventional copper tubes use heat conducting liquid 406 to reserve some space to ensure vaporization. However, in the present application, if space is reserved directly, since most of the heating components such as memory sticks are placed horizontally, they will accumulate on one side of cavity two 4031, that is, the heat absorption is uneven. By connecting several collective heat absorption mechanisms 4 to the heating element heat absorption cover plate 1, the collective heat absorption mechanism 4 transfers the heat of the heating components inside the chassis to the heating element heat absorption cover plate 1, and exchanges the heat through the heat conducting copper tube 3 and the heat exchange fins 2 through the heating element heat absorption cover plate 1, making full use of the heat exchange performance of the heat exchanger, while reducing the surface temperature of other components in the chassis, and further reducing the temperature inside the chassis.

[0034] Specifically, the heat absorbing portion 403 of the heating element is bonded to the surface of the heating element by a thermally conductive adhesive 404. A groove 405 is provided on the outer wall of the heat absorbing portion 403 of the heating element. The inner side of the second cavity 4031 is provided with a filling mechanism 5. The filling mechanism 5 includes an airbag 501. The airbag 501 is bonded to the inner wall of the second cavity 4031. An inlet and outlet pipe 502 is integrally connected to the airbag 501. The end of the inlet and outlet pipe 502 is connected to the outer wall of the heat absorbing portion 403 of the heating element. There is an increasing space between the outer side of the inlet and outlet pipe 502 and the inner wall of the heat absorbing portion 403 of the heating element. A sealing ring 504 is added, and the inlet and exhaust pipes 502 are provided with corrugated folds 503. The corrugated folds 503 facilitate the expansion and contraction of the inlet and exhaust pipes 502. A heat-conducting liquid 406 is added to the inner side of the collective heat-absorbing mechanism 4, and the heat-transferring effect is improved by utilizing the heat-absorbing and vaporizing properties of the heat-conducting liquid 406. At the same time, the filling mechanism 5 occupies the internal space of the cavity 2 4031 of the heat-absorbing portion 403 of the heating element, so that the heat-conducting liquid 406 is evenly adhered to the inner walls of the cavity 1 4011 and the cavity 2 4031, so as to fully absorb heat and further improve the heat exchange effect.

[0035] Specifically, at least one conical telescopic portion 506 is installed on the inner wall of the intake and exhaust pipes 502. The conical telescopic portion 506 is in the shape of a truncated cone. A through hole 507 is provided at the axis of the conical telescopic portion 506. The tip of the conical telescopic portion 506 faces the inner side of the airbag 501. The through hole 507 is in the shape of a truncated cone, and the inner diameter of one end is larger than the inner diameter of the other end.

[0036] Specifically, a plurality of auxiliary airbags 508 are distributed inside the second cavity 4031 , and adjacent auxiliary airbags 508 are connected to each other and the auxiliary airbags 508 at the ends are connected to the airbag 501 . The auxiliary airbags 508 are distributed at corresponding positions of the groove 405 , so as to facilitate further uniform distribution of the thermal liquid 406 .

[0037] Specifically, a sealing sheet 505 is integrally connected to the inner wall of the port of the intake and exhaust pipe 502. Four fan-shaped sealing sheets 505 form a circle, and adjacent side walls are in contact with each other. The sealing sheet 505 uses its own elastic tension to flatten the inner wall of the intake and exhaust pipe 502 to increase the sealing performance of the intake and exhaust pipe 502.

[0038] The heat pipe 402 is composed of a copper pipe and a soft telescopic pipe. The soft telescopic pipe is telescopic, which makes it easy for the heat absorbing part 403 of the heating element to adapt to heating elements in different positions.

[0039] Specifically, the bottom of the connecting plate 401 has multiple parallel grooves that match the protrusions on the surface of the heat absorbing cover plate 1 of the heating element.

[0040] Specifically, the connection plate 401 and the heat absorbing portion 403 of the heating element are both made of copper.

[0041] Specifically, the conical telescopic portion 506 and the airbag 501 are an integrated structure, and multiple annular grooves 5061 are provided on the inner and outer walls of the conical telescopic portion 506 so that the annular grooves 5061 expand and contract with the airflow.

[0042] Specifically, the heat absorbing portion 403 of the heating element is divided into two symmetrical parts, which is convenient for installing the airbag 501. After installation, the two parts are welded and sealed.

[0043] When in use, the heating element heat absorbing cover plate 1 contacts the heating element through silicone grease, and the temperature of the heating element is transmitted to the heat exchange fins 2 through the heating element heat absorbing cover plate 1 and the heat conducting copper tube 3. In combination with the addition of a fan, the heat exchange effect is improved.

[0044] One end of the connecting plate 401 is bonded to the surface of the heating element heat-absorbing cover plate 1 using thermally conductive adhesive 404. The groove at the bottom of the connecting plate 401 matches the shape of the surface of the heating element heat-absorbing cover plate 1. Then, the heating element heat-absorbing portion 403 is bonded to the surface of the memory stick using thermally conductive adhesive 404. The number of collective heat-absorbing mechanisms 4 can be selected according to the number of memory sticks.

[0045] When the memory stick is under high load, the heat on the surface is absorbed by the heat absorbing part 403 of the heating element and the heat conducting liquid 406 inside, and part of the heat is transferred to the heat absorbing cover plate 1 of the heating element through the heat conducting pipe 402 and the connecting plate 401, and then transmitted to the heat exchange fin 2 through the heat absorbing cover plate 1 of the heating element and the heat conducting copper pipe 3. When the heat conducting liquid 406 absorbs enough heat, the heat conducting liquid 406 begins to vaporize, and the volume increases after vaporization, squeezing the airbag 501, so that the gas inside the airbag 501 is discharged, and the airbag 501 is adhered to the inner wall of the second cavity 4031. Since the volume is reduced after being squeezed, The inlet and outlet pipes 502 are provided with corrugated folds 503 for easy expansion and contraction, and the sealing ring 504 increases the sealing of the connection. The airbag 501 is used to occupy space when the thermal liquid 406 is in liquid state, so that the thermal liquid 406 is in full contact with the inner wall and avoids accumulation in one place. The vaporization of the thermal liquid 406 requires space. Conventional copper tubes use thermal liquid 406 to reserve some space to ensure vaporization. However, in this application, if space is reserved directly, since most of the memory modules are placed horizontally, they will accumulate on one side of the second cavity 4031, that is, uneven heat absorption;

[0046] A heat transfer fluid 406 is added to the inner side of the collective heat absorption mechanism 4, and the heat transfer fluid 406 absorbs heat and vaporizes to improve the heat exchange effect. At the same time, the filling mechanism 5 occupies the internal space of the second cavity 4031 of the heat absorption portion 403 of the heating element, so that the heat transfer fluid 406 is evenly attached to the inner walls of the first cavity 4011 and the second cavity 4031, which facilitates sufficient heat absorption and further improves the heat exchange effect.

[0047] After the power is turned off, the temperature gradually decreases, and the heat transfer liquid 406 gradually liquefies. At the same time, the volume of the heat transfer liquid 406 decreases, and the airbag 501 returns to its original shape under the action of its own elastic force. In the recovery process, air needs to be inhaled. During the inhalation process, the conical expansion part 506 and the through hole 507 are used, especially when the through hole 507 is inhaled, the port diameter is reduced, which increases the speed of inhalation. The speed is increased and the pressure is reduced. By lowering the temperature, the airbag 501 and the inside of the heat absorption part 403 of the heating element can be further cooled, which helps to improve the heat exchange effect. At the same time, the annular groove 5061 similar to the bellows on the conical expansion part 506 is stretched as the gas flows during the intake, such as Figure 7 As shown, the elongated conical telescopic portion 506 has an optimized effect on increasing the gas velocity.
