Description of the new type: [Technical field to which the new type belongs] This creation is an improvement of a loop-type radiator structure, especially a main structure (a secondary porous tube core including an evaporator, a main core and a compensation chamber) and The structural design of the evaporator tube, condenser and liquid return tube makes it conducive to mass production, and the principle of gas-liquid separation is used to achieve the best heat dissipation efficiency in a loop type. [Previous technology] With the rapid development of science and technology, electronic products have developed rapidly. Under the trend of lightness, thinness, shortness, smallness and refinement, coupled with the increasing demand for performance, the relative power used must increase. The higher. In this way, the requirements for smaller size and greater power will increase the heating density of the surface of electronic components, and the corresponding heat treatment problems will become very difficult. This can be done from, for example, computer CPUs, VGA cards, North and South Bridge chip sets, or The high-efficiency heating effect of rail components such as rail components is verified. Therefore, 'how to rely on the heat dissipation problem in a limited space domain to ensure the normal operation of electronic products has become a _technical issue and entanglement needs that need to be addressed today. The source case bk has its performance. Under certain operating conditions, the traditional heat pipe has a large thermal conductivity and is now widely used in electronic heat, such as the heat dissipation of the computer's internal CPU. Due to its capillary structure Thin force and shell: Although the inner wall of the entire heat pipe provides the backflow of working fluid to the hair core, its flow resistance inside the capillary structure has also become the main decreasing loop heat pipe of the pressure drop (L 〇0 p Therapy Condenser, steam section, condenser,

P94156a 5 M282236 For 'object road heat' and the principle of operation θ * hair 15 (1 a) inside there is a group of capillary structures (wickt U Γ e) (1b) ° on the wall of the evaporator (1 a) or capillary ... structure_ (lb) There are many channels—the vapor channel (10, such as the working principle of AA truncated 2007). The capillary structure (1 b) itself can suck up the tanker, so that the capillary structure (ib) is filled with clever liquid, and when the base When the hair dryer (! A) is heated, the capillary structure (lb) is also heated, and the capillary structure b) will evaporate, with the same domain secret amount; when the gas is condensed along the vapor section (2 a), n (3 a), the gas is condensed into a liquid, and the capillary force of the capillary structure (ib) causes the liquid to flow back to the compensation chamber (5a) along the return section (4㈧) to obtain the capillary structure (ib). Loop. The driving force of the working medium in the loop heat pipe mainly comes from the capillary force generated by the capillary structure (1b), so the capillary force must be greater than the flow of the working medium between the various elements of the system, resulting in a drop. The system can operate stably. This is the so-called capillary limit. If the flow caused by heat input exceeds the capillary Time-Limited _ Circulation of the working medium fails, and the charm can not provide the working medium liquid to return in time, and the circuit heat pipe will dry out (drv ^ +, a each 1 y 〇ut) phenomenon. Because the traditional heat pipe has the above disadvantages, so αΗ P) The design provides a good way to improve. Because its capillary structure (丄 b) exists only in the evaporator (1a), and the transmission path uses a smooth pipeline, compared to the entire transmission complex, the internal liquid working fluid only accounts for-a small part of the flow in Maozuru The capillary force can be increased at the new age, and the same material will increase the flow resistance of the liquid working medium in the capillary tube. This can effectively overcome the problems of anti-gravity operation and long-distance heat transfer flow resistance. This creation and the traditional heat pipe are mainly P94156a 6 M282236 2 Different Kushiro heat officials are based on the separation of the gas-liquid channel = parallel to the condensed Lai working medium, which is carried by the Weiwei heat pipe ^ 'so it can withstand higher watts than the heat pipe It can be used for designing, and it can be used in various situations because of its pipeline. It is quite capable of conforming to the current electronic production. It is highly efficient, thin and light. [Creation purpose] The author has Zhong Yu The development of the efficiency of the conventional heat pipe has almost reached the neck level, and the conventional loop heat pipe is limited by the miniaturized mass production technology and price factors, and has not yet been widely used in the folk electronics industry; therefore, it is proposed that mass production can reach high efficiency. The overall design of the loop heat pipe and the heat dissipation efficiency of Hangda Shunjia are its main creative purposes. [New content]-An improvement of the loop-type heat dissipation & structure, mainly including the main structure, the main structure system is a flat vacuum-sealed metal shell, a condenser, and a steam tube on one side of the main structure The liquid working medium channel at the bottom of the main core is connected, and the other side is connected to the compensation chamber of the main structure by a liquid pipe. The main structure includes a secondary porous tube core as an evaporator, a main core and a compensation chamber. When the evaporator absorbs external heat, the liquid working medium in the capillary structure is also heated, evaporates into vapor and is at a saturated temperature and pressure, and the gas is a liquid working medium channel dish from the main core of the evaporator & quot U · Into the steam pipe, and through the condenser, the gas is condensed into a liquid, returned to the compensation chamber of the main structure through the liquid return pipe, and reaches the capillary structure layer, so as to form a loop to work repeatedly to achieve the loop type High-efficiency heat sink. [Embodiment] P94156a 7 M282236 In order to make the money-dance solution to make a more specific embodiment, and cooperate with the drawings Niu Benchuang ^ μ θ _ The embodiment is detailed as described below. Seeing the first-four pictures, this creation is an improved design of the flat-shaped circuit crying organization. Qian Zuo's principle rides __scale Zhuan ^. This work is mainly composed of the main structure ⑴, the steam pipe ⑵, and the condenser door. = Liquid pipe ⑷, etc .; where the main structure ⑴ is L flat plate = vacuum-tight side metal shell, which contains the secondary porous tube core of the scale evaporator (Work 2), the main core (13) and the compensation chamber ( 11) It is composed of Yin U. The evaporator is a metal sintered body (such as copper, antimony, titanium, etc.), and the compensation chamber is a liquid working medium (such as water, = _, etc.); and the bribe contains two kinds of capillary wicks. It is the main core (i 3), the bottom is the liquid channel (i 3 丄), and 1- is the secondary porous tube core (i 2), which is composed of multiple vapor channels. When the evaporator receives external heat, the liquid in the capillary structure is also heated, evaporates into healing gas and is at a saturated temperature, but because of continuous heating in the channel, the main g of the evaporation ^ (1 3) The liquid red matter channel (i 3 i) is superheated vapor. The gas moves from the groove along the crane's ditch (1 3) of the evaporator to the condensing point (2 i) of the vapor tube (2), and the vapor has undergone a sudden enlargement process. , So the temperature and pressure have dropped, but still overheated. The Lai process is depleted due to the structure loss. The heating element will be heated into superheated steam during this process. The superheated gas from the steam convergence point (2 i) moves to the end (2 2) of the steam section of ② Qiguan (3), and the superheated steam gradually becomes saturated steam. If it is adiabatic in this process, the superheated gas will produce isothermal lye due to the large size of the road. When the isothermal expansion button moves from the end of the steam section ^ (2 2) to the condensation section (31) of the condenser (3) (the condensation section is the most P94156a 8 M282236 1 a steam node), because the gas will heat the outside, part of the steam condenses Becomes ▲ the liquid is the first liquid node (3 2) in the condensation section, but it is still full = state (note that the 'condensation section (31) (the last steaming node of the cold bet) and the first liquid in the condensation section Node (3 2) is not the gas-phase interface or the liquid-phase interface at the gas-liquid boundary). At the first liquid node (3 2) in the condensation section, the liquid is continuously cooled to all become colder liquid at a lower temperature, and then returns to the other end (41), and under the action of capillary force, the liquid from The front end of the return section j 41) moves to the compensation chamber (丄 丄), and because of the resistance loss, the compensation is to the lowest point of the pressure in (1 1). Also because of the continuous heating of Maozaki structure, the heat is reversed. Passed to the compensation t (work), so the process from the front end of the return section (4 1) to the compensation chamber (ii) is _ warming. Because the capillary force sucks the test object at the compensation chamber (1 1) toward the capillary knot and sucks 1 The capillary structure continues to be heated, so the compensation chamber (ii) to the secondary porous wick (i 2) is a process of adding 但. However, because the compensation chamber (1 1) is connected to the high-temperature Maozaki structure and; The temperature is not the lowest. It should be noted that the compensation chamber (the gas / liquid two-phase coexistence, so it is also on the saturation line. The secondary porous tube core (the liquid _ plus _ evaporation temperature scale at the place, the occupational examination of the students Run away to the liquid working medium channel (丄 3 丄). Capillary tube in the loop heat sink H Core-secondary porous finding (1 2), die (1 3) and the traditional fresh-like function, mainly = soil provides capillary chicken power and depends on the flow channel 1, the ideal core should also have more High capillary force and === system However, more capillary force usually requires smaller pore size, but smaller means lower permeability. Therefore, in order to effectively achieve the freshest _capillary = P94156a 9 M282236 permeability requirements , This creation by Mao Qiqiu_Metal powder hair dryer composite sintered die: the main search (13) ("two = micron pore material, ultra-fine pore warp) + two-stage porous camping early, and coarse burn fine . '(J) at the bottom of the coffee (i 3) (= can effectively and quickly sew to the management tube Wei Xingyu H) ::! Core (2, larger capillary pore size can reduce its thermal conductivity? Ready to reduce to the (2) end The bottom structure of the other large through hole (& it is used to effectively improve the compensation chamber (1; L) to accumulate the lumps (the fourth picture is the main core). Its purpose is to be burned in the second picture) The field trenching is so low that the main junction can meet the source H gas quickly. Next, the loop heat pipe is compensated to (1 1) "cold green (3). The interaction of liquid redistribution, this effect causes the automatic adjustment of the loop heat pipe (a U t 〇g 1 at 1 Q n) characteristic 'Under this characteristic, the scale heat pipe is possible = thermal resistance; in practice,' appropriate design The behavior of the mosquito shooter can be controlled by controlling the temperature of the returning liquid to achieve the purpose of actively adjusting the temperature. In summary, the structure designed by this creation is indeed conducive to mass production, and achieves the circuit type. The heat dissipation n high-efficiency residual effect is far superior to the habitualist in terms of its progressiveness and industrial value, and it has applied for a new patent application according to law. The specific embodiments described above are used to explain the purpose, characteristics and The j effect is only part of the embodiment of this work. When it is not possible to limit the scope of this creation & anyone who is familiar with such skills, according to the above description, and according to the following general patent patent riding structure Equivalent transformations or amendments to the effectiveness of P94156a 10 M282236 have been included in the scope of the patent rights of this creation without departing from the spirit of this creation.
