Description

TECHNICAL FIELD

[0001] The utility model relates to a heat dissipation module, especially a cooling circulation heat dissipation piece which can help electronic devices maintain appropriate working temperature and an electronic device with the cooling circulation heat dissipation piece. BACKGROUND

[0002] Nowadays, electronic devices such as notebook computers not only have excellent performance, but also are always advancing towards thin and light trend; however, electronic devices are prone to generate a large amount of waste heat when operating, which leads to the temperature rise of electronic devices, increases the thermal failure rate and consumption rate of electronic devices. Therefore, the heat generated by heat sources such as chips in electronic devices is usually introduced into a cooling circulation module with better heat dissipation efficiency. Further, the existing cooling circulation module drives working liquid to flow by pumping, so that the working liquid can circulate between the heat absorption area and the heat release area, thereby taking away the heat energy of the heat source to achieve the purpose of heat dissipation.

[0003] However, the working liquid is prone to be stirred by the pump or to generate many air bubbles when flowing against the flow channel, and these air bubbles can easily generate noise when flowing back to the pump by the whipping of the pump.

[0004] Therefore, the existing cooling circulation module still needs to be improved. SUMMARY

[0005] To solve the above problems, the purpose of the utility model is to provide a cooling circulation heat dissipation piece which can reduce air bubbles in the working liquid.

[0006] The secondary purpose of the utility model is to provide an electronic device which can have lower noise when operating.

[0007] The directional or approximate language in the entire description of the utility model, such as "front", "back", "left", "right", "up (top)", "down (bottom)", "inside", "outside", "side", etc., mainly refers to the direction of the attached drawings, and each directional or approximate language is only used to assist in describing and understanding each embodiment of the utility model, and is not used to limit the utility model.

[0008] The quantifier "one" or "a" used for the elements and components recorded in the entire description of the utility model is only used for convenience and provides the general meaning of the scope of the utility model; in the utility model, it should be interpreted as including one or at least one, and the single concept also includes multiple cases, unless it obviously means other meanings.

[0009] The "combination", "combination" or "assembly" and other similar terms described in the whole text of the utility model mainly include the state that the components can be separated without damaging the components after being connected, or the components cannot be separated after being connected, and the skilled in the art can select according to the material quality of the components to be connected or assembly requirements.

[0010] The cooling circulation heat dissipation member of the utility model, comprising: a shell; and a flow channel located in the shell, the flow channel has at least one gas collection area, the at least one gas collection area has a liquid inlet part and a liquid outlet part, the liquid inlet part and the liquid outlet part can have at least one expansion section therebetween, the at least one expansion section has a first side and a second side, the first side and the second side are opposite in a Y direction of the shell, the first side is higher than the liquid inlet part and the liquid outlet part in the Y direction, the flow channel has a liquid collecting area, the liquid collecting area has a diameter expansion section and a diameter reduction section in the Y direction from the liquid outlet part of the at least one gas collection area to a liquid outlet of the shell in sequence.

[0011] Therefore, the cooling circulation heat dissipation member of the utility model, through the flow channel having at least one gas collection area, the at least one gas collection area can have a spacing between the liquid surface of a working liquid and the flow channel by the at least one expansion section, thereby forming a space for gas bubbles to enter after floating up, the working liquid can gradually reduce the gas bubbles in the working liquid when circulating in the flow channel, thereby reducing the gas bubbles, and the effect of reducing the noise and abnormal sound of the cooling circulation module can be achieved.

[0012] The gas collection area extends in an X direction of the shell, and the cross-sectional size of the at least one expansion section is greater than that of the liquid inlet part and the liquid outlet part. In this way, when the working liquid enters the at least one expansion section from the liquid inlet part, the liquid surface of the working liquid can have a spacing with the inner wall surface of the at least one expansion section.

[0013] The second side is inclined from the liquid inlet part to the liquid outlet part. In this way, the working liquid can have better flow smoothness in the gas collection area, and the working liquid is further away from the first side to increase the space for gas bubbles to enter.

[0014] The at least one expansion section is further tapered away from the second side. In this way, the space between the liquid surface of the working liquid and the first side can be expanded.

[0015] The first side and the liquid inlet part are connected by a bevel, and the first side and the liquid outlet part are connected by a bevel. In this way, the at least one expansion section can have a space extending in the direction of the liquid inlet part and in the direction of the liquid outlet part, which can form a dead angle where the working liquid is difficult to flow into, thereby ensuring the space for collecting gas bubbles in the working liquid.

[0016] Wherein, the liquid inlet and the liquid outlet can have several expansion sections. In this way, the working liquid can sequentially flow through the several expansion sections, so that the bubbles in the working liquid can be fully floated out.

[0017] Wherein, the housing has a liquid inlet, the flow channel has a first end connected to the liquid inlet, and the flow channel has a second end connected to the liquid outlet, and the reduced diameter section is adjacent to the second end. In this way, the liquid outlet can maintain sufficient liquid output, thereby enabling the pump to smoothly draw out the working liquid from the liquid outlet.

[0018] Wherein, the liquid collection area is located between the gas collection area and the second end. In this way, the working fluid flowing out of the gas collection area can enter the liquid collection area, thereby enabling the pump to pump in.

[0019] Wherein, the at least one gas collection area is located at the highest position in the direction, so that the at least one gas collection area is adjacent to one end of the housing in the Y direction, and the first end and the second end of the flow channel are adjacent to the other end of the housing in the Y direction. In this way, the bubbles in the working liquid can easily accumulate upwards to the gas collection area.

[0020] The electronic device of the utility model has the cooling circulation heat dissipation piece described above. In this way, the cooling circulation heat dissipation piece can achieve the effect of reducing noise and abnormal sound when the electronic device is operating.

[0021] Wherein, the electronic device has a main body and a screen back plate that are folded relative to each other, the main body has a heat absorption unit, the housing of the cooling circulation heat dissipation piece is located on the screen back plate, and the flow channel of the housing is connected to a chamber of the heat absorption unit through several communication pipes. In this way, the heat energy transferred to the cooling circulation heat dissipation piece can be dissipated to the outside through the screen back plate, and the heat energy of the heat absorption unit can be effectively taken away through the continuous circulation of the working liquid, thereby helping the electronic components to dissipate heat and maintain a proper operating temperature.

[0022] Wherein, the several communication pipes are made of flexible material. In this way, the several communication pipes can be bent when the notebook computer is folded without affecting the flow of the working liquid. BRIEF DESCRIPTION OF DRAWINGS

[0058] In order to make the above and other objects, features and advantages of the present application more comprehensible, preferred embodiments will be described in detail below with reference to the accompanying drawings. In the drawings, like reference numerals refer to like elements throughout. The embodiments of the present application will be described and explained with additional reference to the drawings in which:

[0059] Please refer to Figure 1 , Figure 2 , which is a first embodiment of the cooling circulation heat-dissipating member M of the present application, comprising a housing 1 and a flow passage 2. The flow passage 2 is located in the housing 1.

[0060] The housing 1 can be arranged in an electronic device to cool the heat source in the electronic device by water cooling. In the present embodiment, the housing 1 can be arranged in a notebook computer N. The notebook computer N has a main body N1 and a screen back plate N2 which can be folded relative to each other. The main body N1 can have heat sources such as processors, display chips or memories.

[0061] Please refer to Figure 2 , Figure 3 , the housing 1 can be made of copper, aluminum, titanium, stainless steel or other heat-conducting materials. In detail, the housing 1 can be generally in the form of a thin plate which can be conveniently arranged on the screen back plate N2 of the notebook computer N. In the present embodiment, the housing 1 can have a first plate 1a and a second plate 1b which can be combined relative to each other by hot pressing or welding. The housing 1 can have an inlet 11 and an outlet 12 which can be used for a working liquid L to enter or exit the flow passage 2.

[0062] The flow channel 2 is located in the shell 1 for the working liquid L to flow, for example, the working liquid L can be driven to flow by a pump P, the pump P can be located outside the shell 1, or the pump P can be located in the shell 1, or the flow channel 2 can pass through the pump P, and the utility model is not limited. The flow channel 2 can be recessed in the first plate 1a, or the flow channel 2 can be recessed in the second plate 1b, or the first plate 1a and the second plate 1b recess to form a part of the flow channel 2 respectively, and the utility model is not limited. The flow channel 2 can have a first end 2a to connect the liquid inlet 11, and the flow channel 2 can have a second end 2b to connect the liquid outlet 12. The part of the flow channel 2 between the first end 2a and the second end 2b can pass through the form of a plurality of straight channels and a plurality of curved channels to lengthen the length of the flow channel 2, and make the flow channel 2 almost cover the inside of the shell 1.

[0063] The flow channel 2 has at least one gas gathering area 21, the gas gathering area 21 extends in an X direction of the shell 1, the at least one gas gathering area 21 has a liquid inlet part 21a and a liquid outlet part 21b, and at least one expansion section 21c can be provided between the liquid inlet part 21a and the liquid outlet part 21b, so that the size of the at least one expansion section 21c in a Y direction of the shell 1 is greater than that of the liquid inlet part 21a and that of the liquid outlet part 21b, in other words, the cross-sectional size of the at least one expansion section 21c is greater than that of the liquid inlet part 21a and that of the liquid outlet part 21b. Further, the at least one expansion section 21c can have a first side 22 and a second side 23, the first side 22 and the second side 23 are opposite in the Y direction, the first side 22 can be higher than the second side 23, and the first side 22 can be higher than the liquid inlet part 21a and the liquid outlet part 21b. In this embodiment, the at least one gas gathering area 21 can be located at the highest position in the Y direction, so that the at least one gas gathering area 21 can be adjacent to one end of the shell 1 in the Y direction, and the first end 2a and the second end 2b of the flow channel 2 can be adjacent to the opposite end of the shell 1 in the Y direction.

[0064] Thus, when the notebook computer N is in use and the screen back plate N2 is in a substantially upright state (relative to the placement of the notebook computer N), the working liquid L entering the amplification section 21c can be affected by gravity and flow adjacent to the second side 23, so that the working liquid L and the first side 22 can have a spacing, i.e., the spacing forms a space through which the working liquid L does not flow. When the working liquid L flows through the gas collection area 21, the bubbles in the working liquid L can float into the space formed by the spacing. Preferably, the second side 23 can be inclined from the liquid inlet portion 21a to the liquid outlet portion 21b, i.e., inclined in a direction away from the first side 22. Thus, the working liquid L can have better flow smoothness in the gas collection area 21, and further causes the working liquid L to be away from the first side 22 to increase the space for the bubbles to enter.

[0065] Preferably, the flow channel 2 can have a liquid collection area 24 adjacent to the second end 2b of the flow channel 2. Preferably, the liquid collection area 24 can be located between the gas collection area 21 and the second end 2b. The liquid collection area 24 can sequentially have a diameter expansion section 241 and a diameter reduction section 242 in the Y direction. The diameter reduction section 242 can be lower than the diameter expansion section 241, and the diameter reduction section 242 can be adjacent to the second end 2b. The second end 2b is connected to the liquid outlet 12. When a large amount of working liquid L enters the liquid collection area 24, the working liquid L is limited by the diameter reduction section 242, so that only a relatively small amount of working liquid L can be sent out by the liquid outlet 12, and thus the working liquid L can be partially accumulated in the diameter expansion section 241. In particular, when the screen back plate N2 is in a substantially upright state, the working liquid L can be affected by gravity and accumulated from the diameter reduction section 242 to the diameter expansion section 241. Thus, the liquid outlet 12 can maintain sufficient liquid output, i.e., the working liquid L can constantly fill the liquid outlet 12, and thus the pump P can smoothly draw the working liquid L from the liquid outlet 12.

[0066] Please refer to Figure 1As shown, the shell 1 is provided with the screen back plate N2 as an example, the host body N1 can have a heat absorption unit H, the heat absorption unit H can be used to contact a heat source, the heat absorption unit H can have, for example, a heat pipe to transfer the heat energy of the heat source, the heat absorption unit H can have a plurality of chambers H1 for the working liquid L to flow through. The liquid inlet 11 and the liquid outlet 12 of the shell 1 can be connected to the plurality of chambers H1 through a communication pipe T respectively. The plurality of communication pipes T are flexible structures, such as heat-resistant plastic hoses or metal hoses, etc. In this way, the two communication pipes T can be located at the opposite folding positions of the host body N1 and the screen back plate N2, and the two communication pipes T can be folded with the notebook computer N to form a bend without affecting the flow of the working liquid L. In this way, the working liquid L can circulate between the heat absorption unit H and the shell 1 after being driven, thereby bringing the heat energy of the heat absorption unit H into the shell 1 to dissipate.

[0067] Please refer to Figure 4 As shown, it is the second embodiment of the cooling circulation heat dissipation device M of the utility model, and the second embodiment is basically the same as the first embodiment described above. In the second embodiment, the at least one expansion section 21c can be gradually expanded in the direction away from the second side edge 23, so that the first side edge 22 and the liquid inlet portion 21a are connected by a bevel 21d, and the first side edge 22 and the liquid outlet portion 21b are connected by a bevel 21d. In this way, the at least one expansion section 21c can have a space extending in the direction of the liquid inlet portion 21a and in the direction of the liquid outlet portion 21b, thereby expanding the space between the working liquid L liquid surface and the first side edge 22, and forming a dead angle where the working liquid L is difficult to flow into, thereby ensuring the space for collecting bubbles in the working liquid L.

[0068] Please refer to Figure 5 As shown, it is the third embodiment of the cooling circulation heat dissipation device M of the utility model, and the third embodiment is basically the same as the first embodiment described above. In the third embodiment, the at least one gas gathering area 21 has a plurality of expansion sections 21c, which are arranged in sequence from the liquid inlet portion 21a to the liquid outlet portion 21b. In this way, the working liquid L can flow through the plurality of expansion sections 21c in sequence, so that the bubbles in the working liquid L can be fully floated out.

[0069] In summary, the cooling circulation heat dissipation device of the utility model has at least one gas gathering area in the flow channel, and the at least one gas gathering area has a spacing between the working liquid surface and the flow channel through the at least one expansion section, thereby forming a space for the bubbles to enter after floating up. When the working liquid circulates in the flow channel, the bubbles in the working liquid can be gradually reduced, thereby reducing the bubbles, and achieving the effect of reducing the noise and abnormal sound of the cooling circulation module.

[0070] Although the utility model has disclosed by using the above preferred embodiment, it is not used to limit the utility model, any person skilled in the art is not in the spirit and scope of the utility model, relative to the above embodiment, various changes and modifications still belong to the technical scope of the utility model, therefore the protection scope of the utility model should include the text meaning recorded in the appended claims and all changes in the equivalent scope. Again, when the above several embodiments can be combined, the utility model includes any combined embodiment.
