Description

Technical Field

[0001] The utility model relates to the technical field of annular heat pipes, in particular to a novel loop heat pipe condenser structure. Background Art

[0002] A loop heat pipe is a closed loop heat pipe, which is generally composed of an evaporator, a condenser, a liquid reservoir, and steam and liquid pipelines. The working fluid evaporates on the outer surface of the evaporator capillary core, and the generated steam flows out of the steam channel into the steam pipeline, and then enters the condenser to condense into liquid and supercool.

[0003] Traditional loop heat pipe condensers are struggling to meet the growing demand for heat dissipation. Most existing condenser structures suffer from high thermal resistance and low heat dissipation efficiency. During heat conduction, limited material thermal conductivity and the thermal resistance of the contact interface hinder rapid heat transfer from the heat source to the condenser's heat dissipation area. This is particularly true in high-power, compact devices where traditional condenser structures cannot meet the high-intensity heat dissipation requirements. To address this, we propose a novel loop heat pipe condenser structure. Utility Model Content

[0004] The purpose of the present invention is to provide a novel loop heat pipe condenser structure to solve the problems raised by the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions: a novel loop heat pipe condenser structure, comprising a heat conducting block, a cold water pipe installed inside the heat conducting block, a plurality of heat exchange pipes embedded inside the heat conducting block, the heat exchange pipes communicating with the left and right sides of the heat conducting block;

[0006] Connecting components for inputting steam and outputting condensing pipes are installed on both sides of the heat-conducting block, a plurality of heat-conducting plates are installed on the surface of the heat-conducting block, a plurality of heat-dissipating fins are installed on the surface of the heat-conducting plate, and an air-cooled heat-dissipating component is installed on the surface of the heat-dissipating fin.

[0007] Preferably, the heat exchange tube is wavy.

[0008] Preferably, the connection assembly includes a connection cover, and the two connection covers are fixedly mounted on the left and right sides of the heat conducting block respectively. A heat pipe is connected to one side of the connection cover, and the cold water pipe passes through the connection cover.

[0009] Preferably, the heat conducting plate is fixedly mounted on the surface of the heat conducting block by means of bolts, and a silicone heat conducting pad is provided between the heat conducting block and the heat conducting plate.

[0010] Preferably, the air-cooled heat dissipation component includes a U-shaped support plate, which is fixedly installed on one side of the heat conduction plate. The surface of the U-shaped support plate is provided with heat dissipation fins, and the surface of the U-shaped support plate is equipped with multiple heat dissipation fans.

[0011] Preferably, the air outlet portion of the heat dissipation fan corresponds to the perforation position.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. This new loop heat pipe condenser structure allows the steam in the heat pipe to enter the heat exchange tube through a connecting cover. Multiple heat exchange tubes can divert the steam to ensure that the steam is fully condensed. The condensed liquid enters the connecting cover on the other side and leaves the heat pipe. The heat exchange tube adopts a wavy structure, which increases the steam flow time in the heat exchange tube and ensures the condensation effect.

[0014] 2. This new loop heat pipe condenser structure uses a water pump to supply cold water to the cold water pipe. The cold water flowing in the cold water pipe can efficiently dissipate heat from the heat conductive block. A heat conductive plate is installed on the outside of the heat conductive block, and heat dissipation fins are installed on the surface of the heat conductive plate, so that the heat of the heat conductive block can be dissipated through the heat dissipation fins.
