Abstract
The utility model relates to a high effective full moist solar heat collector which comprises a transparent cover plate, an absorber plate core, upper and lower connecting channels, a heat-insulating layer, an oblique baffle, a press cover and a case. Every flow channel of the absorber plate core and the upper and the lower connecting channels are in a tube-plate two-in-one integral form. The upper and the lower circumferences of the longitudinal section of each flow channel form a flat arc shape. Fifteen to twenty flow channels can be arranged on each absorber plate core which has the width of 1M. In the heat collector, the contact area of heat carrying fluid and the interior of an absorber plate is almost equal to the surface area pf the absorber plate. The utility model has the characteristics of more flow channels, lower flow channel heat-carrying capacity, no combining thermal resistance, excellent heat transfer property, high thermal efficiency and good supporting performance.
Description
The utility model belongs to a kind of solar energy heat utilization device, relates to the architecture advances of solar thermal collector.
Solar thermal collector is a kind of solar radiant energy to be converted to the device of heat energy, is mainly used in to group or family life hot water is provided.The heat absorption surface of solar thermal collector and the combination of fluid passage are called absorber plate (be commonly called as and be the plate core).It is heat collector " heart ", is to finish light---the key element of heat conversion.The solar thermal collector of present domestic use has following several types by its absorber plate structure difference: 1, tube-sheet type solar thermal collector, and its advantage is simple in structure, makes easily, load performance is good; Its shortcoming be plate with pipe between combine thermal resistance R
bGreatly, heat transfer property is relatively poor.2, flat box type solar thermal collector, big and bearing capacity is poor because of the thermal capacity of its heat transport fluid, be not suitable for being used for the forced circulation system.3, copper aluminium combined solar energy heat collector, it is that copper pipe and aluminium sheet adopt rolling process to be rolled into one, R
b=0, heat transport fluid thermal capacity is little, good heat-transfer, but its tube pitch W(110-120mm) bigger, (18-20mm) is less for special-shaped caliber, and the efficiency factor F ' of heat collector is had certain influence, reduces because of F ' increases with W.In addition because the copper-aluminum composite board core has only 7-8 bar runner, their total surface area only accounts for the 17-18% of heat absorption surface area, and the contact-making surface of fluid and absorber plate is very little, and it is longer that fluid is heated required time, the temperature of fin plate must be higher than tube wall temperature simultaneously, thereby radiation loss is bigger.
The purpose of this utility model is exactly in order to overcome the shortcoming that above-mentioned three kinds of pattern heat collectors exist, and a kind of monoblock type heat-absorbing plate core that adopts tube sheet to unite two into one is proposed, the contact area that makes heat transport fluid and absorber plate inside is the full wet type solar thermal collector of the surface area of absorber plate no better than.
The purpose of this utility model is to be achieved by following architectural feature: it has a heat-absorbing plate core and is arranged in the communication channel up and down that each runner of heat-absorbing plate core two ends and absorber plate communicates, the end face of heat collector has transparent cover plate, and there is heat-insulation layer the bottom between the heat-absorbing plate core.Each runner of said heat-absorbing plate core and the communication channel up and down that communicates with each runner are the integral types of tube sheet unification, promptly be to have runner and the laterally zygomorphic sheet metal of communication channel pregroove marks is involutory up and down, between the periphery of metal frid up and down and conduit, impose the seam weldering then and make by two.On the heat-absorbing plate core on the longitudinal section of every runner the following peripheral be flat arc, whole cross sectional shape such as same olive shape.Spacing between per two runners is 5-25mm.
It is 3-6mm that the longitudinal section flat arc of periphery of said runner can adopt following design parameter: camber h, and chord length c is 30-50mm, and determines the radius of curvature r of this arc by camber and chord length.Thus, can be furnished with 15-20 bar runner on the heat-absorbing plate core of 1m width usually.
Heat-absorbing plate core of the present utility model can adopt stainless sheet steel or aluminium alloy sheet to make.Carry out chemically blackening simultaneously on the surface and handle, make it have the solar spectral selective sorbent surface.
The diameter d of the communication channel up and down at absorber plate two ends is 22-38mm.
The advantage that the utility model had structurally not only been got flat box type heat collector---heat absorption surface itself but also be the component part in multithread road gets again that the advantage of copper aluminium combined type heat collector---runner heat-carrying capacity is little.Simultaneously each bar number of runner doubles manyly than the runner of copper aluminium combined type, has increased the contact-making surface of fluid and absorber plate greatly, is beneficial to rapid raising fluid temperature (F.T.), so the R of this heat collector
b=0, the thermal capacity of heat transport fluid is little, the heat transfer property excellence, heat-absorbing plate core structurally of the present utility model is by two symmetrical arc frids, adopts the integral type of seam weldering be combined between periphery and deep-slotted chip breaker, so load performance is good, in addition, according to the various typical physical data computation of the utility model, the collecting efficiency factor F ' of this heat collector is higher than the collecting efficiency factor of other form heat collectors, and this also characterizes this heat collector and has good heat transfer property and higher collecting efficiency.
