A power heat pipe device

Abstract

The invention discloses a power heat pipe system which mainly comprises a condenser, a return device, a circulating pump, an evaporator, a liquid storage tank and a circuit control element; a liquid inlet end of the return device is connected to the lower part of the working media liquid level in the liquid storage tank, and an air inlet of the evaporator and a steam outlet of the evaporator are connected to the upper part of the working media liquid level in the liquid storage tank; the circulating pump is connected into a liquid inlet end of the evaporator, namely behind a three-way pipe which is arranged at a joint position of the liquid outlet end of the return device and a liquid outlet end of the condenser; and the circuit control element controls the running state of the system. The power heat pipe system solves the problems that the heat pipe heat exchange equipment is incomplete for gas and liquid separation and insufficient in circulating power through the design of the liquid storage tank, the return device and the circulating pump, improves the working efficiency and practicability of a heat pipe, and is simple in whole structure and environment-friendly.

Description

technical field

[0001] The invention relates to the technical field of heat exchange, in particular to a novel heat pipe heat exchange system, in particular to a split heat pipe device with a circulation pump. Background technique

[0002] As a high-efficiency heat transfer element, heat pipes are increasingly used in engineering. Heat pipes are not only widely used in waste heat recovery, cooling of electronic components, etc., but also in the field of traditional heat and mass transfer equipment, heat pipes have a tendency to replace circulating water, circulating oil and steam for heat transfer. When the ambient temperature is low, the heat pipe can also replace the current air-conditioning system as a cooling and temperature control element for electronic equipment, power equipment, computer rooms, and communication rooms.

[0003] Heat pipes have a variety of structural forms, and there are also a variety of classification methods. Classified according to the return f...

[0030] image 3 exist figure 1 On the basis of the power heat pipe device shown, the liquid return device (2) is a vertical liquid guide tube (81) with a certain size and cross-section. The vertical liquid guide tube (81) should be as straight as possible, and its length should be the The distance from the liquid tank (5) to the tee pipe (8) is matched, and its flow rate is controlled by the cross section of its liquid inlet. The highest point in the vertical direction of the entire pipeline cannot exceed the liquid level in the liquid storage tank (5). height, and require the liquid storage tank (5) to be on the upper part of the tee pipe (8), so that there is a certain height difference between the two, so that the liquid in the liquid storage tank (5) passes through the vertical catheter (81) due to gravity Return to the three-way pipe (8), and send to the evaporator (4) through the circulation pump (3). Other components are the same as in Embodiment 1.
