Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to a heat transfer element in more detail and refers to a loop heat pipe. [Prior Art] A loop heat pipe (LHP) is an effective heat sink of 70 pieces; a general loop heat pipe includes an evaporator, a vapor line, and a condensation section (c〇). a ndenser) and a liquid line formed by the above-mentioned components communicating with each other to form a circuit; the circuit is still filled with a working fluid, and the evaporation portion has a capillary structure connected to the heat source; the liquid line and the evaporation portion A compensation chamber is provided between the capillary structures. When the evaporation portion of the loop heat pipe absorbs heat from the heat source, the working fluid in the loop heat pipe also absorbs heat from the heat source to evaporate to form a vapor; the vapor passes through the steam tube. The enthalpy and the wire flow through the condensing portion and are converted into a liquid working fluid by exothermic condensation in the condensing portion, and then the 'I plough body returns to the compensation chamber and the venting portion through the (4) (4) pipeline to complete the cycle. The read fluid repeatedly evaporates, condenses, and knots, continuously absorbs heat and releases heat, thereby achieving the purpose of heat dissipation. As the capillary structure in the evaporation section, since the sintered powder block is a solid powder block, the flow resistance is large, so that it is difficult to start the heat dissipation cycle when the heat source is low in wattage; and, when the working fluid is evaporating at the evaporation portion It is more than the recirculation rate of its liquid line', and it is difficult to suck the working fluid from the compensation chamber to the evaporator, causing the dry heat to be able to reduce the heat transfer capacity of the loop heat pipe. [Summary] This is for the above-mentioned conventional device. Disadvantages, the main purpose of the present invention is to provide a flat type Dixie ## plate type, road heat officer, in the case of a low wattage heat source, the Qingxu Junyi secret room can also be used, and the fresh hair room is not Obstacles, so the flow resistance of the vapor is small, * will cause partial pressure inside the evaporation chamber is too large and difficult to start.

And the evaporation-kneading: the working fluid in the 3G capillary structure absorbs the heat transferred by the 攸~, and the source 9〇; when the working fluid 80 η and the heat received is greater than its latent heat, the working fluid 8 The crucible will undergo a phase change from the liquid to vapor to fill the evaporation chamber 33; the vapor flows from the evaporation chamber 33 into the vaporization outlet 211 and flows into the vapor line 71, and flows along the vapor line η to The condensing line 72; at the condensing line 72, the vapor releases the heat absorbed by itself to the condensing line 72 to exchange heat with the outside, and enhances the heat dissipation effect of the heat by the arrangement of the heat sink 75. After the absorbed heat, the phase change is again performed, and the gas phase is converted into a liquid state; the liquid working fluid 8 转 is pushed by the vapor, and continues to flow to the liquid return line 73 from the liquid inlet 212. Flowing back to the compensation chamber 43 of the compensation module structure 2; by the capillary structure of the second liquid core 40, the working fluid 8〇 is again transmitted to the first liquid core 30 for further supply. Once absorbed The heat from the heat source forms a working cycle. In the above operation flow, the first liquid suction core 30 can be propped up to form the evaporation chamber 33 by the arrangement of the first support frame 50, so that the flow resistance of the steam can be reduced, and in the case of a low wattage heat source, the heat can be used. The resulting vapor flow is circulated for heat dissipation - no hard-to-start conditions arise. In addition, by setting 201024648, the second liquid absorbing core 40 continuously absorbs the working fluid 80 and sends it to the first liquid absorbing core 30, thereby preventing the first liquid absorbing core 3 from being dried. It should be noted that, in the above embodiment, the evaporating module structure 1 is composed of the first liquid absorbing core 30 and the first supporting frame 50, but if the first liquid absorbing core 30 is rigid Sufficiently, the first support frame 50 is not required to be added; similarly, the compensation module structure 2 is composed of the second liquid suction core 40 and the second support frame 60, but if the If the rigidity of the second liquid absorbing core is sufficient, the first support frame 60 may not be added (relative to the above-mentioned, the height of the first liquid absorbing core 30 and the height of the second liquid absorbing core 40) Preferably, the sum is greater than the height of the chamber 23 such that the height of the first liquid absorbing core 30 and the second liquid absorbing core 40 are mutually compressed to allow a larger contact surface for the pressure contact. In addition, the main spirit of the present invention is to separate the hollow compensation chamber 43 and the hollow evaporation chamber 33 from each other by a capillary structure. Therefore, in the design, only a ring-shaped liquid suction core can be disposed on the bottom of the container. The vapor outlet 211 can be correspondingly fitted, so that the effect of the compensation chamber 43 and the evaporation chamber 33 being separated from each other can be achieved, and the annular body absorbing liquid can reduce the flow resistance of the vapor, in the case of a low wattage heat source. It can make the generated steam flow to circulate heat, and it is not difficult to start.
