specific Embodiment approach 2

[0033] 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.

specific Embodiment approach 3

[0035] In a specific environment, in order to exchange the functions of the condenser (1) and the evaporator (4) in the system, that is, the condenser (1) acts as an evaporator, and the evaporator (4) acts as a condenser, Improvements are made on the basis of the first embodiment.

[0036] The circulation pump (3) is replaced by a one-way circulation pump with a two-way power motor system (such as Roots motor) that can directly change the direction, and the pipeline from the connection interface (52) of the liquid storage tank (5) passes through the liquid return device ( 2) It is no longer a branch, but divided into two branches, each branch is connected to a check valve, the direction of the check valve is to flow out from the interface (52), and the check valve installed on one branch The outlet of valve one (21) is connected to the tee pipe (31) between the circulation pump (3) and the condenser (1), and the outlet of one-way valve two (22) installed on the other branch is...

[0043] Figure 5 exist figure 1 On the basis of the power heat pipe device shown, the liquid return device (2) is a liquid return hole (9), which is located at a suitable position on the condenser liquid guide (12). This device requires the condenser liquid guide The pipe of (12) passes through the liquid storage tank (5), and the pipe of the condenser liquid guide (12) is at the lower part of the liquid level in the liquid storage tank (5), and its position is as close as possible to the bottom of the liquid storage tank (5). As a result, the liquid refrigerant stored in the liquid storage tank (5) is concentrated in the condenser liquid pipe (12) through the liquid return hole (9) and the refrigerant output from the liquid outlet of the condenser (1) due to the action of gravity and pressure. It is sent to the evaporator (4) by the circulating pump (3) for circulation. Other components are the same as those in Embodiment 1 or Embodiment 2.

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...
