Five, the specific embodiment

Be example with the stealthy heat reservoir of indoor outfit radiation heat transfer below, the detailed annotation specific embodiment.

General daytime, less with heat, and sunlight is abundant, and the regular solar water heater is because water tank thermal capacity is little, and the solar energy utilization on daytime is also insufficient, and this state is particularly outstanding at summer, sunny weather.At night, comprise thick weather, regular solar water heater thermal-arrest ability, even do not have, heating, bathing but are the peaks.Because of there not being big capacity heat reservoir, energy stored can not satisfy the demands, and heat supply will be interrupted.If the water tank of water heater is done greatly, just not saying it is big to take up space, deadweight also makes Roofing slab be difficult to bear.

This example is based on: combine together with building structure, especially be fit to the building of frame structure.As the facility of intelligent building, pipes such as water, electricity, fire-fighting, communication, cable are pre-buried the same, and unified planning in civil Engineering Design is in case when heat collector is installed, accomplish that precautions averts perils.Though stealthy heat reservoir volume is big, from great, it substitutes one section (or whole face) partition wall, and light relatively on the contrary, soundproof effect is good again.Reasonable integral structure is designed to thickness and is " 37 (or 50) wall ", highly is stud; Width is the series specification prefabricated components of the integral multiple of 0.5m, be placed in indoor, wide because of it, height, thin characteristics, space utilization is abundant, does not additionally take up an area of.Specially make the guard shield outer surface coarse in addition, can make the decoration consistent easily with chamber interior walls.As Fig. 1,2.

The stealthy heat reservoir of background radiation heat exchange is different with traditional country's wall with flues, and function is not the heat radiation heating, but the bulk container that insulation is fabulous.

For obtaining high storage heat density, thermal storage medium 15 adopts cheap gravels and water not, and operating mode belongs to sensible heat storage heat, and the gravel heat absorption is a dead load.In the time of 100 ℃, the specific heat capacity c of gravel is 0.20cal/g ℃, and than 1cal/g ℃ low of water, the density p of gravel is 2.5～2.9g/cm ³, than the 0.96g/cm of water ³Height, both store heat Q=c ρ m close (m is a mass of medium) synthesis result.Gravel is a heat carrier, does not participate in any reaction, need not replenish, upgrade, and the life-span is long, is heated not produce high pressure (and 100 ℃ steam saturation pressure is 10 times of atmospheric pressure, and explosion-proof is a hang-up), and is safe and reliable.

Heat transmission in the packed bed I also has the heat radiation between the particle to conduct heat except the mutual contact conduction of gravel.The thermal conductivity of gravel is lower, is 0.32kcal/mh ℃, is 60% of water, differ from two quantity pebble sizes with metal, so a certain amount of hot superconduction working medium 14 of reinjecting forms space heat-conducting work medium 14 convection current, reduce the thermograde of vertical direction, further quicken heat exchange.

According to the Natural Circulation principle, the heat release heat-exchanging tube bundle 4 at packed bed I middle part is connected with other load, and heat release heat-exchanging tube bundle 4 must have 5% gradient, i.e. the heat release of heat release heat-exchanging tube bundle 4 outlet 6 is higher than heat release and answers back 7, to keep the Natural Circulation of this loop.The hot heat-exchanging tube bundle 8 of storage of bottom is connected with radiation heat transfer heat collector III, and its storage heat inlet 11 and storage heat 10 levels at least of answering back, preferably storage heat enter the mouth and 11 answer back 10 a little more than storing heat, otherwise adverse slope, vent plug can occur, destroy the Natural Circulation of this loop.

In this example, the gravel storage heat in packed bed I, the water in the hot-water coil pipe 3 is also serving as thermal storage medium, can be considered as dynamic load, before using hot water, has stored no small heat.Hot-water coil pipe 3 is positioned at packed bed I top, and the water in the hot-water coil pipe 3 is by tube wall conduction warm, and directly from packed bed I heat absorption, heat exchange fully, rapidly.Why hot-water coil pipe 3 can make coil pipe, because flowing of water wherein is different with heat release heat-exchanging tube bundle 4 with the hot heat-exchanging tube bundle 8 of storage, what lean on is the pressure forced circulation of dispatching from the factory of running water.The purpose of making coil pipe is the line length that lengthening water flows, increase the heat exchange contact area, when the storage heat of packed bed I enough big, when temperature is enough high, water flows constantly to absorb heat on the way and heats up, the arrival exit place has reached bathing temperature (〉=45 ℃), become immediately heating water heater, thereby hot water is provided continuously.

The pedestal II height of packed bed I bottom depends on the installation site of radiation heat transfer heat collector III.One deck room ± 0th, outdoor ground, the pressure head of Natural Circulation requires the heat collector of radiation heat transfer heat collector III 12, the 13 storage heat inlet 11 and the storage heat that all must be lower than the hot heat-exchanging tube bundle 8 of storage that go out, answer back to answer back 10 to not a half rice, can not dig pit drops to heat collector III below the horizon, can only packed bed I be held up by pedestal II.Radiation heat transfer heat collector III can be installed in the wall face place of this floor plate below half meter fully more than two layers, not add pedestal II, packed bed I can increase, and volume strengthens, and the storage heat is then bigger.

The maximum characteristics of the stealthy heat reservoir of the utility model radiation heat transfer are, move into indoor from roof heat reservoir, the tubing pump that does not need forced circulation, place the wall position neither additionally to take up space, do not increase the floor load yet, the distance of shortening and load is beneficial to insulation, reduces the insertion loss in thermotransport and the storage.Next is that hot-water coil pipe 3 and 4 pairs of loads of heat release heat-exchanging tube bundle are relatively independent, does not disturb mutually.Moreover be that system can store heat in the edge work limit, as the floating charge state of battery, the storage heat is enough big, and holding temperature is constant, becomes immediately heating water heater.
