Abstract
The utility model discloses a flexible heat pipe. A flexible connecting tube is arranged between the condensation segment and the evaporation segment of the heat pipe; heat transfer medium is injected in the integrated closed vacuum cavity; the external surface of the condensation segment and the evaporation segment can be provided with smooth tubes or radiating ribs. The external surface of the flexible pipe is provided with anticorrosive coating. The angle between the condensation segment and the evaporation segment of the heat pipe can be of any degree, and the angle can be adjusted freely in the installation process to make the installation easier; the condensation segment and the evaporation segment can both be rigidly fixed without damage to the equipment caused by thermal expansion.
Description
Technical field
The utility model relates to a kind of heat pipe.
Background technology
Since the at first application beginning on satellite of nineteen sixty-eight hot pipe technique, existing so far nearly 40 years history.Though people constantly make improvements for many years, the basic structure of heat pipe still there is not change, no matter is monomer heat pipe or split heat pipe, and its evaporator section and condensation segment link into an integrated entity by rigid pipe, and are provided with heat-transfer working medium in the vacuum chamber of sealing.Its weak point is: can't realize that engineering requires evaporator section and condensation segment need have angle in using, or the angle requirement between evaporator section and the condensation segment is adjusted in requirement arbitrarily, when if engineering all requires fixedly with heat pipe evaporator section and condensation segment in addition, the problem of expanding with heat and contract with cold of its heat pipe itself can't solve common rigidity heat pipe.
Summary of the invention
The purpose of this utility model is to provide the flexible heat pipe that angle can be adjusted arbitrarily between a kind of evaporator section of heat pipe and the condensation segment.The utility model is to be provided with flexible steel in flat section tubing between heat pipe condenser section and evaporator section, this flexible steel in flat section tubing connects into an integral body with evaporator section and condensation segment, and is provided with the heat-transfer working medium that can flow in the vacuum chamber of sealing between evaporator section, condensation segment and flexible steel in flat section tubing.The evaporator section and the condensation segment of above-mentioned heat pipe are rigid pipe, and their outer surface is the same with general heat pipe can be light pipe, also can be provided with all kinds of heat exchanger fins that increase heat exchange area such as fin (screw type or H type), fin, fin etc.This flexible heat pipe is the same with general heat pipe, and appearance can be provided with various anticorrosive coats, perhaps adopts the cathode protection method protection heat pipe of sacrificial anode.
Evaporator section with this flexible heat pipe during use places hot side medium (medium that heat is provided can be liquid, gaseous state and solid-state), condensation segment places cold side medium (medium that absorbs heat also can be liquid, gaseous state and solid-state), utilize the operation power of the temperature difference formation inside heat pipe working medium between hot side medium and the cold side medium, the mutual conversion cycle of vapour-liquid two-phase in the heat pipe, heat in the hot side medium is reached the cold side medium, reach the purpose that reduces hot side medium temperature, heating cold side medium temperature.
The utility model compared with prior art has following advantage:
1, the utility model can be realized the needs of any angle between heat pipe evaporator section and the condensation segment, can arbitrarily adjust angle in the installation process, and it is easier that heat pipe is installed.
2, heat pipe evaporator section and condensation segment all can rigidly fix, and can not cause device damage because of expanding with heat and contract with cold.
Description of drawings
Fig. 1 is the utility model example 1 main innings generalized section of looking.
Fig. 2 is the utility model example 2 main schematic diagrames of looking.
The specific embodiment
Master at flexible heat pipe shown in Figure 1 looks in innings generalized section, but pressure-bearing flexible hose 1 two ends weld together with stainless steel condensation segment 2 and the stainless steel evaporator section 3 that the other end seals respectively, establish heat transfer medium in the vacuum chamber of sealing, condensation segment and evaporator section outside are provided with helical fin 4.Master at flexible heat pipe shown in Figure 2 looks in the schematic diagram, but heat pipe evaporator section and condensation segment that pressure-bearing flexible hose two ends are connected are 20 ° of angles between them.
Claims (3)
1 one kinds of flexible heat pipes is characterized in that: be provided with flexible steel in flat section tubing between heat pipe condenser section and evaporator section, be provided with heat transfer medium in the vacuum sealing cavity that fuses.
2 flexible heat pipes according to claim 1 is characterized in that: the outer surface of its condensation segment and evaporator section can be that light pipe also can be provided with heat exchanger fin.
3 flexible heat pipes according to claim 1 and 2 is characterized in that its outer surface is provided with anticorrosive coat.
