Problems solved by technology
[0005] The invention provides a new loop heat pipe and its heat exchange device. The distribution density of the through-holes in the invention becomes larger and larger, so that the communication area becomes larger and larger, which can ensure the overall pressure balance of the capillary core and avoid local pressure Too large, causing losses to solve the previous technical problems

Embodiment Construction
[0046] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0047] In this article, if there is no special explanation, when it comes to formulas, " / " means division, and "×" and "*" mean multiplication.
[0048] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0049] An anti-gravity loop heat pipe such as Figure 8 As shown, the heat pipe includes an evaporating end 6 and a condensing end 8, the evaporating end 6 is located on the upper part of the condensing end 8, a part of the evaporating end 6 is arranged in the fluid ascending section, and at least a part of the evaporating end of the fluid ascending section is provided with a capillary wick 13, such as Figure 10 shown.
[0050] As a preference, the evaporating end includes two parts: the pipeline from the evaporating end to the condensing end (the descend...

The invention provides an anti-gravity loop heat pipe. The heat pipe comprises an evaporation end and a condensation end, the evaporation end is located above the condensation end, a part of the evaporation end is arranged at a fluid ascending section, at least one part, arranged at the fluid ascending section, of the evaporation end is provided with a capillary core, the center of the capillary core is provided with a pipeline which flows to the evaporation end from the condensation end, the pipeline communicates with the capillary core, and in the height rising direction, the communication area between the pipeline and the capillary core is larger and larger. According to the heat pipe, due to the fact that the communication area between the pipeline and the capillary core is larger andlarger, the overall pressure balance of the capillary core can be ensured, and the loss caused by too large local pressure is avoided.
Description
technical field [0001] The invention relates to a heat pipe and a heat exchange device using the heat pipe. Background technique [0002] In the prior art, heat pipes generally rely on gravity to realize heat pipe circulation, but this kind of heat pipe is only suitable for the situation where the lower part absorbs heat and the upper part releases heat, and it is not suitable for the opposite. Therefore, aiming at this situation, the present invention invents a structure-improved anti-gravity heat pipe by improving the capillary structure. [0003] In the previous application, the applicant applied for an anti-gravity loop heat pipe. The heat pipe includes an evaporating end and a condensing end. The evaporating end is located on the upper part of the condensing end. At least a part of the evaporating end is provided with a capillary core, and the center of the capillary wick is provided with a pipeline from the condensing end to the evaporating end. However, the communic...
