Abstract
A heat collection system capable of two-phase flow heat exchange for through vacuum collector tubes includes through vacuum collector tubes, a bracket, upper and lower water pipes, a heat preservation water tank and a microcomputer measuring and controlling instrument, wherein the collector tubes are horizontally arranged, and the heat collection system is characterized in that a seal ring provided with holes is arranged at a pipe orifice of the collector tubes; the upper part of the seal ring provided with holes is unobstructed, and the lower part thereof is water-retaining; and a tubular heat exchanger is penetrated through along the axial leads of the collector tubes. The heat collection system has the benefits that as the through collector tubes are horizontally arranged, and the seal ring provided with holes and the tubular heat exchanger are combined, water is reserved in the collector tube, so as to realize two-phase flow heat exchange in the collector tubes, and the heat collection system has simple structure and high collection efficiency, and on that basis, the built system has high reliability, is uniform, and can operate while bearing pressure. An embodiment is given in combination with the attached drawing.
Description
Technical field
The utility model relates to two phase flow heat transfer and connects the vacuum heat collection pipe collecting system.
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 to provide two phase flow heat transfer to connect the vacuum heat collection pipe collecting system.
The technical scheme in the invention for solving the technical problem: form a two phase flow heat transfer perforation vacuum heat collection pipe collecting system with connecting vacuum heat collection pipe, support, upper and lower conduit, attemperater and microcomputer measuring and controlling instrument.Thermal-collecting tube is horizontally disposed.At the thermal-collecting tube mouth of pipe sealing ring with holes is set.Unobstructed, the bottom dash in described sealing ring with holes top.Run through a tubular exchanger 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.
Connect thermal-collecting tube and arranged, melted to seal at two openends and make by two glass tube cover glass tubes and inner glass tube nested, concentric, the chuck layer between two glass tubes vacuumizes; Inner glass tube outer surface vacuum sputtering selective absorbing film.
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, the collecting efficiency height.The system reliability height of Zu Jianing, uniform on this basis, but and bearing operation.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is that a two phase flow heat transfer connects vacuum heat collection pipe collecting system compound section structural representation.
1. thermal-collecting tubes among the figure; 2. heat exchanger; 3. sealing ring; 4. through hole; 5. water.
The specific embodiment
Fig. 1 provides an embodiment of the present utility model.
Among Fig. 1, form a two phase flow heat transfer perforation vacuum heat collection pipe collecting system with connecting vacuum heat collection pipe 1, support and upper and lower conduit.Two thermal-collecting tubes, 1 tandem array, horizontally disposed.Run through tubular exchanger 2 of installation along thermal-collecting tube 1 axial line.At thermal-collecting tube 1 mouth of pipe sealing ring 3 with holes is set.Sealing ring 3 with holes contains six through holes 4; The diameter of intermediate throughholes 4 is greater than the diameter of tubular exchanger 2; Sealing ring with holes 3 bottoms do not have through hole.
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 1 inner glass tube absorbing film.Steam is in tubular exchanger 2 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 2 with solar thermal energy by heat exchanger 2.Water intensification fluxion strap in the heat exchanger 2 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 sealing ring 3 with holes.
Claims (2)
1. two phase flow heat transfer connects the vacuum heat collection pipe collecting system, form by connecting vacuum heat collection pipe, support, upper and lower conduit, attemperater and microcomputer measuring and controlling instrument, thermal-collecting tube is horizontally disposed, it is characterized in that the thermal-collecting tube mouth of pipe contains sealing ring with holes, unobstructed, the bottom dash in described sealing ring with holes top; Run through a tubular exchanger along the thermal-collecting tube axial line.
2. according to the described collecting system of claim 1, it is characterized in that sealing ring with holes contains 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.
