Abstract
A through type vacuum heat collection tube with in-tube two-phase flow heat exchange comprises a through type vacuum heat collection tube and porous seal rings, wherein the heat collection tube is horizontally disposed. The through type vacuum heat collection tube with in-tube two-phase flow heat exchange is characterized in that the porous seal rings are contained in openings of the heat collection tube, the upper portion of each porous seal ring is clear while the lower portion of the porous seal ring is water-stopping, and a tubular heater is mounted along an axis of the heat collection tube in a through manner. The through type vacuum heat collection tube has the advantages that the through type heat collection tube is horizontally disposed, water can be reserved in the heat collection tube by the aid of the porous seal rings and the tubular heat exchanger, two-phase flow heat exchange in the heat collection tube is achieved, and the through type vacuum heat collection tube is simple in structure and high in heat collection efficiency. Use of the through type vacuum heat collection tube further can achieve on-load operation of a heat collection device. An embodiment is given with attached figures.
Description
Technical field
The utility model relates to the perforation vacuum heat collection pipe of two phase flow heat transfer in the pipe.
Background technology
Existing vacuum heat collection pipe heat-collecting temperature height, heat waste is little, industrialization level is high, can provide domestic hot-water more than 50 ℃ in the winter time with the cannula type water heater of its manufacturing.But generally speaking, the application product of vacuum heat collection pipe is abundant not enough flourishing.
Summary of the invention
The purpose of this utility model is the perforation vacuum heat collection pipe that two phase flow heat transfer in the pipe will be provided.
The technical scheme in the invention for solving the technical problem:, form the perforation vacuum heat collection pipe of two phase flow heat transfer in the pipe with connecting vacuum heat collection pipe and sealing ring with holes.Thermal-collecting tube is horizontally disposed; At the thermal-collecting tube mouth of pipe sealing ring with holes is set, sealing ring with holes top is unobstructed, the bottom dash; Run through tubular exchanger of installation along the thermal-collecting tube axial line.
Can also make sealing ring with holes contain an above through hole, the diameter of intermediate throughholes is greater than the diameter of tubular exchanger; Sealing ring with holes bottom does not have through hole.
The beneficial effects of the utility model: horizontally disposed perforation thermal-collecting tube, in conjunction with sealing ring with holes and tubular exchanger, can make has water to retain in the thermal-collecting tube, realize two phase flow heat transfer in the thermal-collecting tube pipe, simple in structure, collecting efficiency is high.Adopt heat exchanger can also realize the bearing operation of heat collector.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the perforation vacuum heat collection pipe compound section structural representation of two phase flow heat transfer in the pipe.
1. thermal-collecting tubes among the figure; 2. sealing ring with holes; 3. heat exchanger; 4. through hole; 5. water.
The specific embodiment
Fig. 1 provides an embodiment of the present utility model.
Among Fig. 1,, form the perforation vacuum heat collection pipe of two phase flow heat transfer in the pipe with connecting vacuum heat collection pipe 1 and sealing ring with holes 2.Thermal-collecting tube 1 is horizontally disposed; At thermal-collecting tube 1 mouth of pipe two ends sealing ring 2 with holes is set respectively.Sealing ring 2 with holes contains six through holes 4.The diameter of intermediate throughholes 4 is greater than the diameter of tubular exchanger 3.Sealing ring with holes 2 bottoms do not have through hole, and so both convenient water inlet again can be at the thermal-collecting tube 1 inner water of retaining.Run through a tubular exchanger 3 along thermal-collecting tube 1 axial line.
The operation principle of Fig. 1 embodiment: sunshine converts heat to and makes in the thermal-collecting tube 1 water 5 evaporation that heats up of being heated on thermal-collecting tube inner glass tube absorbing film.Steam is in tubular exchanger 3 surface condensation heat releases.Condensed water falls and is subjected to once again thermal evaporation ..., so going round and beginning again continually passes to water in the heat exchanger 3 with solar thermal energy by heat exchanger 3.Water intensification fluxion strap in the heat exchanger 3 is walked the heat energy supply and is used.
Can be when needing later on by 4 pairs of thermal-collecting tubes of through hole, the 1 inner pure water that replenishes of cushion rubber 2.
