Description

Solar water heater hangs down the heat waste boiler

The utility model relates to the low heat waste boiler of a kind of solar water heater.

The solar water heater boiler of prior art, owing to be installed on outdoor application, majority has adopted polyurathamc directly to inject the foamed heat insulating technology, insulation layer thickness all in 4-5.5 centimetre scope, should be able to reach good heat insulation effect.But find that in actual applications the cooling behind its night and the rain is apparent in view, through the continuous solar water heater of certain several trade mark of actual measurement, the cooling at southern area one night of summer can reach 6～18 ℃, Formula calculate, the heat waste rate at a night all reaches in 0.22～0.32 the scope, well beyond having a normal heat loss rate of high-quality heat-insulation layer.From its reason of textural analysis, find that existing product all has tangible heat waste point (also claiming heat dissipation channel), be provided with a plurality of (4～8) location, supporting member between first boiler and shell, all be that metalwork welding is fixing, scatter and disappear because of the metal good heat-conducting still reaches shell with the heat of boiler though part is little.Product is also arranged for reaching high strength assembling purpose, on the boiler outer wall, be welded with four bearings, wear with four support bolts and to rigidly fix with barrel (support) to the shell, (Chinese patent ZL98205029) is though all be added with rubber sheet gasket between bolt and bearing, between shell, but inevitably also there is contact point between bolt and bearing hole and barrel hole, shim liner etc. does not stop the good heat conductive performance of metal in addition, and constitutes four heat dissipation channels.Two of heat waste point is that auxiliary adapters such as the Inlet and outlet water adapter of boiler and blowdown, overflow, off-load all are that metal tube directly welds with the hot water tank wall, some also with between the outer cover metal plate exists and contacts, and for example think little of insulation and make pipe end joint and valve member all open in air the time, all can constitute good heat dissipation channel.

Hence one can see that, no matter round the clock, heat waste is constantly to take place, just because of there being daytime the sunlight thermal-collecting tube to be difficult for discovering in heating, but the heat waste rate on this daytime can be offseted the part heat absorption rate of thermal-collecting tube, because of low its heat waste rate of temperature can be higher, therefore, the heat waste rate that effectively reduces solar water heater is improved the effective means of the integrated heat efficiency that improves solar water heater just during winter.

The purpose of this utility model provides a kind of heat waste rate that reduces solar water heater, reduces and shutoff heat waste point, has both reduced the cooling behind night and the rain, and the solar water heater that can improve the integrated heat efficiency of solar water heater again hangs down the heat waste boiler.

For achieving the above object, solar water heater of the present utility model hangs down the heat waste boiler, boiler [1], shell [2] are arranged, between boiler [1] and shell [2] heat-insulation layer [3] is arranged, the thermal-collecting tube socket [11] of a plurality of perforation heat-insulation layers [3] and shell [2] is arranged at boiler [1] bottom, be stained with a plurality of locating pieces of making by heat-insulating material [4] on boiler [1] outer wall and between the shell [2], into water adapter [10] is equipped with in boiler [1] bottom and hot water is taken over [12], and its tube head passes heat-insulation layer [3] stretches under the shell [2].

Described boiler [1] lower support position is fixed with wooden the support [5] of several arcs, on the extrados of each support [5] at least setting-in be fixed with 2 iron plate bolts [9], the extrados of support [5] matches with shell [2] inwall, has only the bolt of iron plate bolt [9] to extend outside the shell [2].[10] are taken in water inlet and hot water is taken over [12] outer circular waterproof and heat-insulating guard ring [13] of being with the edge of dripping that is respectively installed with, dripping of waterproof and heat-insulating guard ring [13] along matching with big hole on the shell [2], make the heat of adapter can not reach shell [2], when meeting the rainy day, rainwater drops down the drip edge whereabouts of back along waterproof and heat-insulating guard ring [13] from shell [2], can not flow to pipe.

As further improvement of the utility model, iron plate bolt [9] along setting-in on support [5] extrados is fixing by several screws [14], prop up support [5] and behind the chucking of two ends, hammer into wood screw [8] positioning and fixing again from the outside by a pair of zigzag clamp [7] that is welded on boiler [1] outer wall, the bolt of the iron plate bolt [9] of outer stretches out in outside the shell [2] makes assembling connecting piece, described boiler [1] has only a water inlet to take over [10] and have only a hot water adapter [12], so that the heat waste rate is reduced to is minimum.Water inlet is taken over [10] hot water adapter [12] and is fitted with three-way pipe [6] respectively, to realize blowdown and off-load.For helping pouring foaming, have many translots [5-1] and a pod [5-2] on the internal and external cambered surface of a support [5].For ease of assembling, be provided with preformed hole [5-3] corresponding to the position of iron plate bolt [9] in support [5].

The utility model both can reach between boiler [1] and support be rigidly connected solid and reliable, having stopped boiler [1] again is connected with metalwork between the shell [2], eliminate the heat waste point that positioning mounting constitutes, though this programme still exists a few metals connector to stretch into heat-insulation layer, but it stretches into heat-insulation layer 1/2nd thickness with upper/lower positions, still has heat-insulating property preferably.Propping up the available natural hard timber of support [5] shapes, the direct die forming of density wood chip resin material in also can adopting, has fastness preferably, propping up translot [5-1] and the pod [5-2] offered on the internal and external cambered surface of support [5] is that the circulation of being convenient in the pouring foaming process is avoided the dead angle, form again behind the fluting with inside and outside metallic plate between multiple spot contact, stress point is uniformly dispersed, and contact area reduces.The adapter of low heat waste boiler [1] becomes the heat waste point that can not eliminate entirely, should take to reduce quantity as far as possible, [10] are taken in water inlet and hot water is taken over [12] each so this programme is only established, adapter is not established in other complementary interfaces such as blowdown, off-load etc. separately, and utilize subsidiary three-way pipe [6] to do to divide mouth to connect, again owing to [10] and the outer waterproof and heat-insulating guard ring [13] of being with the edge of dripping that is set with of hot water adapter [10] are taken in water inlet, after installation, carry out the rainproof measure of all risk insurance temperature sealing of taking over again, heat waste is decreased in the minimum zone with pipe fitting.

The utility model simple structure, good manufacturability, the firm stable after the boiler assembling is good, reduces the heat waste rate greatly, and the integrated heat efficiency of solar water heater is greatly improved.

Below in conjunction with Fig. 1, Fig. 2 the utility model is described in further detail.
