The specific embodiment
As shown in Figure 1, this pattern is the operation principle schematic diagram of existing solar vacuum-tube water heater.Its groundwork principle is exactly to utilize vacuum heat collection pipe to absorb solar radiant heat and carry out heat exchange with water in the thermal-collecting tube, and the interior water of the water in the thermal-collecting tube and storage tank circulates by free convection.This water heater is simple in structure, but but there are a lot of defectives in this water heater, at first, in this scheme, water in the thermal-collecting tube relies on free convection to absorb solar radiation heat, the water heater of this structure requires start-up temperature higher, and water circulating speed causes its infiltration rate to solar radiant heat also slow slowly.Especially when illumination condition was relatively poor, this water heater almost can't use.Secondly, be that the reliability of vacuum heat collection pipe of main material is lower with glass, the leakage of single thermal-collecting tube can both cause whole water heater to use, and especially runs into hail weather, and it damages can be more serious.The 3rd, this structure water heater is in order effectively to absorb solar radiation heat, require heat collector to tilt to place, vertical to guarantee the heat collector surface with the sunshine incident direction, this mounting means is had relatively high expectations to installation environment, must be installed in the roof, can not adapt to existing building structure, its reliability is relatively poor, and installation cost is higher.Though wall-hanging solar water heater begins to use in skyscraper, can't break away from tilted-putted drawback all the time, this just must be provided with the inclination installing space for it.Therefore the water heater of this version all can not well combine with the top or the wall of building, water heater can't be used as the top of building or the part of wall in other words, does not realize the architecture-integral on the complete meaning.
As shown in Figure 2, a kind of solar water heater, comprise the water tank 1 that has intake-outlet, heat collector 23, described heat collector 23 comprises casing and at least one row thermal-collecting tube 22 that is arranged in the casing, described casing comprises upper box body and lower part box two parts, and described heat collector comprises the incubation cavity 21 that formed by lower part box and linked to each other by 20, two cavitys of heat exchanging chamber that upper box body forms.Described thermal-collecting tube 22 is through casing up and down among two parts, casing top is full of heating agent around the thermal-collecting tube condensation end and forms airtight heat collector 23 heat exchanging chambers 20 and shelves stream dividing plate 14 is set between two parties, and baffle dividing plate 14 is respectively arranged with heating agent import 16 and heating agent outlet 15 up and down; Be provided with heat exchanger 8 in described water tank 1, the import of described heat exchanger 8 and outlet nature extend to outside the water tank 1 and are communicated with the heating agent import 16 and the heating agent outlet 15 on described heat collector 23 tops respectively; Described thermal-collecting tube 22 is heat pipe or oscillating heat pipe.Described water tank 1 and heat collector 23 split settings, the import and export of heat exchanger 8 are passed through pipeline connection with import 16 of heat collector heating agent and heating agent outlet 15 respectively, effectively reduce the volume and weight of plug-in part, reduce cost, and solve antifreeze problem.Described heating agent is a glycol water, and its condensation temperature can reach-35 ℃, effectively solves the antifreeze problem of the heat collector of outdoor setting.
At the described stacked heat transmission fin that is provided with in thermal-collecting tube 22 surfaces that is arranged in lower part box, effectively increase endotherm area.Described heat transmission fin is that umbrella fin 17 is sleeved on thermal-collecting tube 22 surfaces, absorbs solar energy to greatest extent.Described heat transmission fin is a sheet fin 19, sheet fin plane, 19 place and thermal-collecting tube 22 axes intersect.Be provided with heat exchange fin 18 on described thermal-collecting tube 22 surfaces that are arranged in upper box body, increase heat exchange area.Upper surface cover glass steel deck-plate at described lower part box.
The heat transmission fin surface is coated with coating for selective absorption, and 22 solderings of heat transmission fin and thermal-collecting tube are connected.
This is a mode of operation of the present invention, this pattern has fundamentally changed the tilted-putted drawback of solar water heater, solved consequent many contradiction, employing is with the method for inclined plane dispersed placement, and when realization level (Fig. 5-6) or vertical (Fig. 2-3) place and inclined plane produces same assimilation effect.Introduce oscillating heat pipe or heat pipe simultaneously in this scheme as the conducting-heat elements of its core, realized cold-starting, quick conductive, the advantage of high reliability such as anti-icing anti-pressure.In this scheme, inclining fin at oscillating heat pipe or heat pipe fire end outer surface, when heat collector vertically or can both guarantee that the heat transmission fin surface is vertical with the sunshine incident direction during horizontal positioned, the heat transmission fin surface is coated with coating for selective absorption with to the incident light efficient absorption, adopt soldering to be connected between heat transmission fin and oscillating heat pipe or the heat pipe, almost do not have thermal resistance, heat can be conducted to oscillating heat pipe or heat pipe fire end by heat transmission fin rapidly like this.In oscillating heat pipe, working medium under low pressure is subjected to thermal evaporation and absorbs heat, steam promotes the fluid column in the oscillating heat pipe, liquid-vapor mixture arrives oscillating heat pipe condensation end (heat collector heat exchange box part), at condensation end, steam is led heat to low temperature heating agent and condensation with heat by the heat exchange fin on condensation end pipeline and the pipeline, and the liquid of condensation is moved on by the promotion of back liquid-vapor mixture and gets back to fire end, and the circulation in the oscillating heat pipe has just been finished like this.Upwards flow after heating agent is heated, the low temperature heating agent continues to be heated, and just takes heat to storage tank by pipeline by the free convection heating agent like this, at storage tank high temperature heating agent heat is led to cold water, heat collector is got back in the heating agent cooling, and heating agent is also finished circulation like this, and cold water is heated.Can certainly add a pump as required and drive heating agent acceleration circulation, strengthen heat exchange efficiency.In heat pipe, have only heat-transfer mechanism and oscillating heat pipe in the heat pipe to distinguish to some extent, the heat transfer process of other parts is identical.At inside heat pipe, heat is under low pressure evaporated and absorbed to working medium, and steam rises and becomes liquid and emit heat in heat pipe condensation end (heat collector heat exchanging chamber) condensation, and heat is led to the low temperature heating agent, and condensed working medium is got back to fire end by thin liquid core and finished circulation.Therefore compound cooling system of the present invention can efficiently dispel the heat.
The connection request of oscillating heat pipe or heat pipe and inclining fin is very compact among the present invention, the space can not be arranged, otherwise influence heat exchange, so the present invention intends adopting soldering tech that oscillating heat pipe or heat pipe and fin are welded.The present invention selects the material of red copper as oscillating heat pipe or heat pipe for use, and fin adopts copper sheet or aluminium flake, and its arrangement form has umbrella or staggered floor to arrange, as shown in Figure 2.
Heat transmission fin layout angle and spread pattern can design according to actual needs, can be not less than the heat absorption capacity that conventional bevel is placed solar water heater to guarantee heat collector.
