Description

Plate-type modular solar heater collector

The present invention relates to known flat-plate solar heat collector.

The heat-absorbing plate core of known flat-plate solar heat collector all is contained in the holistic insulation casing, structural representation as shown in Figure 1, heat-absorbing plate core [1], transparent cover plate [2], thermal insulator [3], housing [4], heat-absorbing plate core [1] is integrally welded by heat-collecting strip [11] and the collector that confluxes [5], can't dismantle, wherein heat-absorbing plate core [1] is installed in by transparent cover plate [2], in the sealing insulation casing that thermal insulator [3], housing [4] surround, use the greenhouse effects principle and make solar thermal collector.Enclose rich this known flat-plate solar heat collector, structure at it has now been done some functional technological improvements, as the collector [5] that confluxes is changed into rubber tube by metal tube, utilize the characteristic of rubber to make heat collector improve freeze proof performance, but again can easily scale removal; And for example for the comb of scale removal on the row's same heat-absorbing plate core of short tube [1] of burn-oning on the collecting pipe [5] connects one by one, this short tube stretches out the incubator housing, cleans the dirt in the comb easily outside heat collector, improves service life.Further promoted the scientific and technological progress of flat-plate solar heat collector, but these improve and also exist shortcoming, though anti-freezing property has solved substantially, but the thawing rate of the collector that confluxes is slow excessively, has significantly influenced heat collector at the thermal efficiency on the same day, has reduced the quantum of output of hot water, for scale removal also must be taken the housing [4] that is connected firmly apart by the professional, remove transparent cover plate [2] and thermal insulator [3] then again, reinstall trouble very and specialty after the scale removal again; Weld nipple on the collector that confluxes has made things convenient for scale removal, but has increased production technology and cost, has significantly reduced production efficiency, and in a word, they take off all the time technically and be unable to do without the insulation casing.

The objective of the invention is to propose a kind of plate modular solar thermal collector, not only can easily scale removal but also can be freeze proof, convenient with multiple different solar heat-preservation water tanks combination, solderless is delivered a child and is produced the efficient height, helps forming higher-quality product.

The objective of the invention is to realize, the heat-collecting strip [11] in the heat-absorbing plate core of the flat-plate solar heat collector of conventional known [1] and the collector that confluxes [5] organically are separated into separately two modules partly, be connected again at last by such structure.Specifically be with orderly being arranged in the insulation casing of the heat-collecting strip [11] of heat-absorbing plate core, it is a part of so that stretch out housing [4] that the comb port [12] of heat-collecting strip [11] one or both ends extends heat-collecting strip [11], utilize housing [4] to fix heat-collecting strip [11], perhaps use the fixture [41] that mutually firmly is connected with housing [4] to connect and fixing heat-collecting strip [11], by the same housing of heat-collecting strip [11] [4], transparent cover plate [2], thermal insulator [3] constitutes an independent heat-collecting heat-preserving body, is referred to as heat collecting module.Conflux collector [5] and thermal insulator [3], shell [42] or whole separately by the collector that confluxes [5] formation one separately, be referred to as confluence module, because all be modular construction, therefore can very easily heat collecting module part and confluence module part be constituted modularized solar energy collecting device of the present invention mutually.Wherein the comb port [12] of heat collecting module part is connected combination with the seal [51] of the collector that confluxes of confluence module part and need not weld, be connected firmly by elaxtic seal, easy accessibility, the processes well known technology maturation, reliability is high.Pull down the confluence module part and just can easily clean the interior dirt of each heat-collecting strip [11] comb, because used the structure of confluence module, can efficiently utilize thermal insulator [3] that the collector that confluxes [5] is incubated easily, the collector [5] that confluxes is not-easy-to-freeze, comb just is difficult for bursting by freezing, improves the ability of the anti-freezing property and the hot water that resumes production rapidly.The collector [5] that confluxes is gone up and is twined electric heating heating line.

With regard to architectural feature of the present invention and embodiment, conjunction with figs. further specifies now.
