[0001] The utility model relates to the technical field of heat dissipation, in particular to an evaporator loop heat pipe. Background Art

[0002] A loop heat pipe is a highly efficient two-phase heat transfer device with high heat transfer performance, long-distance heat transmission and excellent temperature control characteristics. It mainly includes structures such as evaporator, condenser, liquid storage tank and steam pipe. Since loop heat pipes have many unparalleled advantages over other equipment, they have very broad application prospects in many fields such as aviation, aerospace and heat dissipation of ground electronic equipment.

[0003] However, the existing evaporator loop heat pipe, as the liquid continues to flow into the evaporator, the liquid level will rise to a certain height, causing the liquid level to be higher than the steam outlet, causing part of the liquid to flow to the condenser along the steam outlet, resulting in an increase in the amount of liquid in the steam and reducing the heat exchange efficiency. To this end, we provide an evaporator body loop heat pipe to solve the above problems. Utility Model Content

[0014] 3) Beneficial effects:

[0015] Compared with the prior art, the evaporator loop heat pipe has the following beneficial effects:

[0016] 1. The utility model cooperates between the evaporator body, the water collecting tank, the water pipe, the water sensor and the alarm. When the liquid level in the evaporator body is higher than the steam outlet, the liquid level will touch the water sensor, and the water sensor will trigger the alarm through the conduction line. At this time, it is only necessary to open the valve of the evaporator body to drain the water. This solves the problem of the existing evaporator body loop heat pipe. As the liquid continues to flow into the evaporator body, the liquid level will rise to a certain height, causing the liquid level to be higher than the steam outlet, so that part of the liquid flows to the condenser along the steam outlet, resulting in an increase in the amount of liquid in the steam and a reduction in heat exchange efficiency.

When the liquid level in the evaporator body is higher than the steam outlet, the alarm sounds, and the information is transmitted to the switch block through the signal line. The switch block can open the telescopic rod, and the telescopic rod drives the pressure plate to move downward to rotate the valve, thereby automatically opening the water collecting tank, solving the problem of the existing evaporator body loop heat pipe that most of the valves are opened manually to drain water when the alarm sounds, and the degree of automation is not high.
