Abstract

The utility model relates to a solar water heater with a natural circulating split heat pipe-a vacuum pipe, relating to a domestic solar water heater. In utility model which adopts a natural circulating water flowing mode, a solar heat collecting tube with a heat pipe-a vacuum pipe is used as a heat collecting element; the heat pipe of the solar heat collecting tube with a heat pipe-a vacuum pipe, which is inserted in a water flowing channel for a connecting box, forms transversal flushing heat exchange water flow in the connecting box. The utility model which is not provided with a control element and a valve has the advantages of convenient installation, convenient maintenance, high heat efficiency, no scale deposit in pipes, no easy explosive fission, no easy damage, safe running, high reliability, low cost, and no easy freezing, and in addition, the utility model can be used in a severe cold region. A glass pipe is not directly impacted by cold water and hot water.

Description

Natural Circulation separated heat pipe-solar vacuum-tube water heater

The utility model relates to a kind of domestic solar water heater, particularly a kind of split type domestic solar water heater.

At present, the solar water heater that uses in the prior art, the overwhelming majority is the monolithic devices water heater, promptly storage tank and heat collector combine as a whole.This kind water heater is not easy to go up installation at dwelling house (especially high residential building) because shared spatial area is bigger.For addressing this problem, a kind of split-type structural has appearred in the prior art, and be about to heat collector and storage tank branch and be arranged, such as heat collector is hung on the balcony wallboard, and that storage tank is placed on is indoor, can address the above problem preferably like this.But in the split-type structural that adopts at present, its heat collector adopts vacuum tube directly leak water mode, i.e. constant temperature delivery water method more.This kind structure exists following deficiency and defective: because vacuum tube is impacted by hot and cold water directly, pipe easily bursts, and easily scales in the pipe; At severe cold area, easily freezing, and damage the difficult replacing in back; Because the water in the header is in vexed solarization state, the thermal efficiency is also lower.

The purpose of this utility model and task are deficiency and the defectives that exists at prior art, a kind of Natural Circulation separated heat pipe-solar vacuum-tube water heater is provided, this water heater not only installation, maintenance is convenient, heat collecting element is difficult for bursting, damaging, safe and reliable to operation, and cost is lower, thermal efficiency height.

The utility model is achieved through the following technical solutions: it mainly comprises heat collector, walks water manifold and storage tank three parts, its heat collector and storage tank branch are arranged, and it is heat collecting element that heat collector adopts heat pipe-type-vacuum heat collection pipe, it is characterized in that walking adopting between water manifold and the storage tank Natural Circulation pipeline to be connected, heat pipe in the heat collecting element inserts away in the water manifold runner, with the current formation transversal flow heat exchange in the header; Described storage tank mainly comprises the automatic water replenishing device that is connected with upper hose, be contained in the hot and cold water demarcation strip of storage tank one end, be located at below the constant water level the high-order heat-obtaining water pipe of lower slightly and with walk hot water tedge 9 that water manifold 2 links to each other and cold water down pipe 10 etc.

Heat pipe inserts away in the runner of water manifold 2, with the current formation transversal flow heat exchange in the header, with the water in the heat transferred header of vacuum heat collection pipe absorption.Hot water after the intensification is along hot water tedge inlet chamber inner storing water case, and water in water tank flows into the outdoor water manifold of walking along cold water down pipe simultaneously, forms the mode of leaking water of Natural Circulation.

Accompanying drawing 1 is a structural principle schematic diagram of the present utility model.

Accompanying drawing 2 is the structural representation of storage tank.

Accompanying drawing 3 is the aluminium chassis structural principle schematic diagram of band governor motion.

Describe concrete structure of the present utility model, operation principle and preferred forms in detail below in conjunction with accompanying drawing: it is mainly by heat collector 1, walk water manifold 2 and storage tank 3 these three parts compositions, heat collector 1 adopts the heat pipe type solar double-glass vacuum heat-collecting tube 4 that has obtained Chinese utility model patent (ZL95214285.6) to be heat collecting element, one end of its heat pipe 5 inserts away in the water manifold 2, and heat is passed to water in the header.Walking water manifold 2 links to each other with storage tank 3 with cold water down pipe 10 by hot water tedge 9; Because the proportion of hot water is lighter than cold water, be raised to the top of standpipe from an end of header along the hot water tedge, simultaneously, the cold water in the storage tank drops to the other end of header, finishes Natural Circulation (also the claiming thermal siphon) process of water.Cold water enters storage tank 3 through water inlet pipe 13, one end of storage tank is provided with hot and cold water dividing plate 7, enter the bottom of the cold water of storage tank, hot water is pushed up storage tank top, make the water level in the storage tank maintain a constant altitude by the automatic water replenishing device 7 that is installed in the top along dividing plate inflow storage tank.Heat-obtaining water pipe 8 is located at the lower slightly below this constant water level 14, can obtain the hot water in the storage tank, has guaranteed that also shower nozzle has a high as far as possible pressure head simultaneously.Heat pipe 5 inserts in the runner of water manifold 2, forms the transversal flow heat exchange with current in the header, like this can enhanced heat exchange, further improve the thermal efficiency.

For the ease of daylighting, heat collector 1 can place in the aluminium chassis 11 of band governor motion 12, easily the angle of integrally-regulated heat collector.

In order to prevent that vacuum tube from breaking, the heat collector surface is provided with a high-intensity steel wire 12,

The utility model compared with prior art has the following advantages and beneficial effect: this heat Hydrophone not only installation, maintenance is convenient; And because heat collector adopts heat pipe-type-vacuum heat-collecting Pipe inserts away in the runner of water manifold heat pipe, with the current shape in the header for heat collecting element Become the transversal flow heat exchange, so thermal efficiency height; Glass tube is not impacted by the hot water or cold water directly, Do not scale in the pipe, therefore be difficult for bursting, damaging, safe and reliable to operation; Employing follows naturally The mode of leaking water of ring has saved control element and valve, the reliability height, and cost is low; Sternly Cold area also is difficult for freezing.
