Description of the invention: [Technical field of invention] Measuring system for working fluid evaporation performance The present invention relates to the field of heat transfer technology, and in particular to a measuring method thereof. • [Prior Art] In recent years, the rapid development of electronic technology, the high frequency, high speed of electronic devices and the intensive and miniaturized circuit of the integrated circuit, so that the high volume of heat generated by the county's volumetric shirts is released. There are three kinds of private I7 air-cooling heat sinks, liquid heat sinks and heat pipes. Air-cooled scatter (4) 目细娘, _ 赖读娘补(4) Thermal device, the heat-generating heat generated by the heat source is transmitted to the complex bulk, and then the larger wire area of the hot-selling film is 'ship--(four)_ In addition, the convection, the convection of the convection will be the view of the cooling boat. However, there is a large thermal resistance between the red lion, the tank and the relay, and between the heat sink and the air. The heat transfer rate is slower and the heat dissipation efficiency is lower. It is usually only applied to electronic devices with low heat generation. Compared with the air-cooled political heating device, the liquid-cooled heat-dissipating device can greatly reduce the heat of the electronic device, and at the same time, it has the same material, the job type, and the high contact rate, which becomes the main way of dissipating heat when sanding electrons. The age-type residual device is purely--the evaporation in contact with the heat source, and the cooling connected to the evaporator. [The secret hair device and the cold (four) medium-age liquid flow transfer the heat so that the flow of the secret depends on the temperature difference. When the temperature difference is large, the temperature difference is large, indicating that the heat generated by the heat source does not obtain a good heat dissipation effect, and there is such a contradiction between the flow rate of the gj and the heat dissipation effect, thereby limiting the heat conduction efficiency of the liquid cooling heat sink. 1320090 The flow of working fluid to heat transfer, the pass f includes the shell and

When hot, the heat transfer efficiency with the heat pipe depends on the flow velocity of the X body. However, the conventional heat pipe does not improve the flow velocity of the coolant ▲, which severely limits the heat transfer efficiency of the heat pipe. In view of this, it is necessary to provide an efficient heat dissipation heat pipe that can accelerate the flow of the working fluid. SUMMARY OF THE INVENTION Hereinafter, an efficient heat dissipation heat pipe capable of accelerating the flow of a working fluid will be described by way of example. The present invention provides a heat pipe comprising a hollow sealed casing having a cavity therein; a working fluid sealed in the casing; and a rotating device disposed along an axial direction of the cavity, It is used to accelerate the flow of working fluid in the heat pipe. The rotating device includes a rotating shaft provided at an end portion of the inner wall of the casing and an agitating member formed on the rotating shaft. The heat pipe further includes a driving device disposed at a position corresponding to the end of the rotating shaft of the housing for driving the rotating shaft. Compared with the prior art, the heat pipe provided by the technical solution utilizes the rotation of a rotating device and can forcibly accelerate the circulating flow of the working fluid in the heat pipe under the agitation of the agitating member, thereby increasing the heat transfer rate, thereby improving the heat transfer of the heat pipe. effectiveness. 1320090 [Embodiment] The present invention will be further described in detail below with reference to the accompanying drawings. Clearly - and referring to the first and second figures, the heat pipe provided in the first embodiment of the present invention is a heat pipe which is a single pipe type heat pipe, including a hollow sealed casing m, which has __ empty a cavity 12〇; • a JL sealed in the set body 11G as a fluid 130; a rotating device 140 disposed axially along the cavity 12G for accelerating the flow of the working fluid 13 in the heat pipe 1〇〇; The driving device 150 in the end portion of the casing 丨1〇, the hollow sealing casing 11〇 generally includes an evaporation end A1 and a condensation end, and the evaporation end A1 is in contact with a heat source 16〇. When the contact area is increased, a heat dissipating patch 112 can be disposed on the Al portion of the evaporating end. When the heat pipe 100 is used, the heat dissipating patch 112 is closely attached to the heat source 16 〇, and the heat generated by the heat source 160 can be quickly and massively transferred to the heat pipe 1 . Hey. The material of the housing 110 may be selected from a thermally conductive metal material such as aluminum, copper, silver 'iron, nickel, titanium or an alloy thereof. This embodiment uses copper metal. The rotating device 140 includes a rotating shaft 142 and an agitating member 144 formed on the rotating shaft 42. Preferably, the agitating member 144 is integrally formed with the rotating shaft 142 and can be formed by an integral injection molding, welding or gluing technique. The rotating shaft 142 of the rotating device 140 is disposed between the inner wall of the end portion of the heat pipe 1 And a bearing 145 is disposed on the inner wall of the condensation end Β1 to rotatably fix the rotating shaft 142. In order to rotate the rotating shaft 42, a magnet 146 can be disposed at the end of the rotating shaft 142 near the condensation end Β1, and the driving device 15 is disposed on the housing 110 corresponding to the magnet 146. The driving device 15 of this embodiment The crucible includes a magnet 152 relative to the magnet 146 and a control device 154 for controlling the rotation of the electromagnet 152. The rotation of the electromagnet 152 drives the rotation of the magnet 146 to drive the rotating device 14 to rotate about the rotating shaft 142 1320090. The magnetic material may be directly used for the end portion of the rotating shaft 142 near the condensation end B1 or the entire rotating shaft 142 may be made of a magnetic material, so that the magnet 146 can be omitted. In addition, the evaporation end ai and the end B1 can be respectively designed to match the structures of the two ends of the rotating shaft 142. • The rotating device (10) the reading member 144 may be a spiral seal that is connected to the body, or may comprise a plurality of blades that are interlaced with each other, and the blade body can be accelerated by the rotating device 14 to accelerate the working fluid. 130 Any blade of any shape flowing from the evaporation end A1 to the condensation end B1, for example, the shape of the blade can be spirally wound by the winding 142 and inclined toward the condensation end BH, and the inner surface of the blade can be a tapered surface. Or a conical surface (such as a bowl-shaped inner surface). The material of the blade can be selected from metal or plastic, etc. In this embodiment, a spiral plastic blade integrated into one body is used. The working fluid 130 may be selected from the group consisting of water, methanol, ethanol, ammonia, acetone, heptane, etc., and water is used in this embodiment. In addition, the heat pipe 100 is further provided with a return passage 114 along the inner surface of the housing 110. The return passage 114 is axially connected to the housing 110 and the cylinder 116 is fixedly coupled to the inner surface of the inner surface of the housing 11 The φ rib 丨丨 8 is formed, and the cylindrical body 116 and the inner wall of both ends of the heat pipe 1 are spaced apart by a certain distance. Therefore, when the heat is conducted from the heat dissipation patch 112 to the evaporation end A1, the end working fluid 130 is heated, and then driven by the rotating device 140 to the condensation end Bi of the heat pipe 1 ,, and then the heat is released at the end. The return channel 114 flows back to the evaporation end A1, that is, a heat dissipation cycle is completed. Referring to the third figure, a heat pipe provided in a second embodiment of the present technical solution is a one-circuit type heat pipe 200, and the main structure thereof is basically the same as that of the heat pipe ι, except that the heat pipe 2 〇〇 basic structure The structure of the singularity includes a stencil-shaped hollow sealed casing 210 having a rotary cavity 220 therein; a working fluid 230 sealed in the casing 210; and being disposed in the rotary cavity 220 1320090 a rotating device 240; and a driving device 250 disposed at one end of the casing 2丨〇. Moreover, the heat pipe 200 also has an evaporation end A2 and a condensation end B2' and a heat dissipation patch 212 is disposed on the evaporation end A2. The rotating device 240 of the heat pipe 200 has the same basic structure as the rotating device 热4〇 of the heat pipe 100, and has a rotating shaft 242 and a stirring member 244. The rotating shaft 242 has a magnet 246 disposed at the end of the rotating shaft 242, and is rotatably fixed. Bearings 245 at both ends of the shaft 242. The difference is that the heat exchanger 2 is disposed in the cavity of the evaporation end A2 after the working fluid 230 is condensed by the condensation end B2, and is disposed along the axial direction of the section 220. Corresponding to the position of the rotating device 240, the driving device 250 can be disposed on the housing 210 at a position similar to the magnet 246, and the housing 210 corresponding to the magnet 246 forms an indented recess 216 to accommodate the driving. Device 250' The drive device 250 of the present embodiment includes a magnet 252 relative to the magnetic light 246 and a control device 254 that controls the rotation of the electromagnet 252. In order to accommodate the rotating device 240, the cavity 220 of the portion may have a larger internal space, and the cavity 220 for the section of the working fluid 23 that is heated to flow to the condensing end B2 may adopt a smaller internal space to The flow of the working fluid 230 in the entire cavity 22 is brought to a balanced state, so that the partial working fluid 23 is not excessively flowed and the overall flow rate is hindered. Alternatively, the flow guiding member 2 丨 8 ' 219 ' may be disposed at a portion where the working fluid 230 flows away from the evaporation end A2 and flows into the condensing end μ to allow the flow of the corresponding junction to flow smoothly. The working fluid 230 of this embodiment may also be water, ? Alcohol 'ethanol, ammonia, _, ship and other liquids, and add thermal conductive nano particles to these liquids, including nano-ply, silver powder, m or nano carbon materials (such as nano carbon balls and naphthalene tubes), Thereby forming a floating liquid, the suspension of the present implementation of the Nacai and the carbon nanotubes. 9 1320090 Since the working fluid 230 contains nano particles, not only can the flow rate of the working fluid 230 be increased when the agitating member 244 of the rotating device 240 rotates, but also the nano particles in the working fluid 230 can be searched for to prevent it. The aggregation effect is generated', so that the agitation of the agitating member can enhance the dispersion of the nanoparticles, further increasing the heat dissipation effect of the working fluid 230. 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 The body 310 has a cavity 320 therein, and the working fluid 330 is sealed in the casing 31. The rotating device 340 disposed in the cavity 320 includes a rotating shaft 342 and a search member 344. The driving device 350 is disposed at the end of the rotating shaft 342. Moreover, the heat pipe 300 also has an evaporation end A3 and a condensation end B3, and is provided with a heat dissipation patch 312 attached to the evaporation end A3. The structure of the heat pipe 300 is different from that of the heat pipe 100 in that the cavity 32 of the heat pipe 3 is axially divided into a heat flow chamber 321 and a cold flow chamber 322 by a partition plate 360. The partition plate 360 is a flat plate and is connected to the heat pipe. The evaporation end A3 of 300 and the inner wall of the condensation end B3 are spaced apart such that the two cavities 321, 322 can be electrically conducted through the interval. Preferably, the baffle 360 can be tilted toward the condensing end B3 such that the working fluid 330 condensed or collected on the baffle 36 can be directed along the inclined baffle 360 to the cold flow chamber 322, or the baffle 36 The cross section of the tube in the radial direction is formed into an arch shape, and micropores are formed at a portion in contact with the casing 310, and the above-described flow guiding effect can also be achieved. In order to enhance the condensation effect of the condensation end B3, the heat pipe 3〇〇 further includes a plurality of heat dissipation fins 37〇 formed on the outer surface of the casing 310 at the condensation end B3. The driving device 350 can adopt a motor 354, and extend the rotating shaft 342 to the outside of the heat pipe 300 and directly connect to the motor 354. The contact gap between the rotating shaft 342 and the housing 310 can be rotationally fixed by a bearing 345, 10 1320090. The shaft 342, while the bearing 345 also has a sealing function to prevent leakage of the working fluid 33. Generally, the working fluid 330 is filled in the cold flow chamber 322. When the heat pipe 3 is operated, the working fluid 330 in the cold flow chamber 322 is heated and evaporated at the evaporation end A3, and the vapor of the working flow Zhao 330 rises to the heat flow. And rapidly diffusing in the heat flow chamber 321 to the condensation end B3, under the cooling of the heat sink Korean 360, condensing into a liquid working fluid 330' by the tilting action of the partition 360 or its own gravity, the condensed work fluid 330 flows to the heat flow The cavity 321 is close to the condensing end B3 ping #, and then the working fluid 330 is accelerated to return to the evaporation end A3 by the rotating device 34 ,, that is, one heat-dissipating cycle of the heat pipe 3 完成 is completed. The cross-sectional shape of the casings 110, 210, and 310 in the above embodiments is not limited to a circular shape, and may be various desired shapes such as a flat plate shape or an elliptical shape. Moreover, in order to rapidly transfer the heat generated by the heat source to the heat pipe 'the evaporation end of the heat pipe A A2, A3 may also adopt other structural forms, such as pressing the evaporation end A A2, A3 to the heat source part into a flat shape In order to match the shape of the heat source surface, the heat of the heat source can be quickly and massively transferred. Alternatively, a heat sink having a heat-dissipating base and a plurality of heat-dissipating fins can be combined with the heat-dissipating end of the Al and A2' A3 portions. The A2 and A3 are inserted into the heat sink base. The heat of the heat source can be quickly and massively transferred to the heat pipe and then emitted. At the same time, the condensing ends B2, B3 and the condensing end B1 may be provided with a plurality of heat dissipating fins or other heat dissipating means for enhancing condensation at the end. Further, the heat pipe of the present invention is not limited to the heat pipe structure of each of the above embodiments, and may be of a different structural form as long as the structure of the above-described rotating device can be applied. By utilizing the rotation of the above-described rotating device, the circulating flow of the working fluid in the heat pipe can be forcibly accelerated to increase the heat transfer rate, thereby improving the heat transfer efficiency of the heat pipe. 1320090 In summary, the invention conforms to the requirements of the invention patent, and loves to file a patent application according to law.
