The specific embodiment

The example of relevant first invention Roof thawing contructure, as shown in Figures 1 to 4.This Roof thawing contructure is that to have the heat interchanger 1 of the collection underground heat energy of non freezing solution to be embedded vertically at inner loop underground, and this non freezing solution is transported to the heat release pipe 2 that is laid on roof 6 by circulation pipe 3, utilizes this heat energy to be melted in the accumulated snow on roof 6.

At this example, heat interchanger 1 is the concentric double pipe that inserts inner core 1b in the urceolus 1a of lower end closed with the identical center of circle, and this end portion is buried underground and is positioned at the dark lithosphere R of underground 100m～200m.And heat release pipe 2 is joined end to end in total length by outlet 2a and loop 2b and is the hair clip sigmoid and forms, to guarantee all evenly heat releases.

Above-mentioned heat release pipe 2 is fixed on the roofing slab 7, and between roofing slab 7 and watts 8, spread be mixed with numerous metal small pieces (spherula of aluminum) 10 cover a roof with straw soil 9.

Besides circulation pipe 3 is provided with pump 4 that makes the non freezing solution circulation and the open and close valve 5 of adjusting the non freezing solution flow.The sticking asphalt felt 13 of paying on roofing slab 7 is fixed with watt stack 12 simultaneously at certain intervals again.Heat-barrier material 14 and hold-down bars 15 are housed below roofing slab 7 in addition.

The following running of this Roof thawing contructure.At first primer pump 4 begins to supply with non freezing solution with this upper part from the inner core 1b of heat interchanger 1, and invades among the gap path 1c that forms between this end portion and urceolus 1a, and the underground heat energy that collects is upwards transmitted like this.The non freezing solution that collects underground heat energy is transported to heat release pipe 2 by circulation pipe 3, and discharges heat energy at this.

The heat energy that discharges from heat release pipe 2 is to begin to be delivered on watts 8 from covering a roof with straw soil 9, and melts the accumulated snow on watts 8.At this moment because sneak into countless spherulas 10 in 9 covering a roof with straw soil with aluminum of good heat conductivity, thus the heat energy that discharges from heat release pipe 2 can efficient good pass to watts 8, to reach effective snow melt effect.

The example of relevant second invention Roof thawing contructure is as Fig. 1, Fig. 2, Fig. 5 and shown in Figure 6.This roof construction has the spherula 10 of sneaking into aluminum in covering a roof with straw soil 9, and laying has the feature of the copper coin 11 of good heat conductivity on heat release pipe 2 simultaneously.Therefore the heat energy that discharges from heat release pipe 2, the spherula 10 by copper coin 11 and aluminum are can efficient good passes to watts 8, can more resultful thawing snow on watts 8.This copper coin 11 can be arranged on all of roof 6, also can only be arranged on the latter half on the roof that is easier to pile up a large amount of accumulated snow.

Heat interchanger 1 can also be other a object except concentric double pipe mode, can be the object that is the U font as shown in Figure 7.This U font is that the core at tube body 1d is provided with dividing wall 1e and forms two path 1f, supplies with non freezing solution since the path 1f of a side, discharges non freezing solution from the path 1f of opposite side.

Pump 4 is except that source power supply, can also utilize device of solar generating and internal combustion engine TRT to turn round.Device of solar generating is as shown in Figure 8, utilizes solar panels 16 to absorb sunshines, and the battery 19 accumulator box 17 in charges by controlling substrate 18 when needs charge, and by rectifier 20 electric power of necessity is offered pump 4 again.

The effect of invention

The Roof thawing contructure of record is to utilize by heat exchanger 1 to collect in the claim 1 Underground heat energy carry out snow melt, these are different from the occasion of utilizing underground water, do not bring out ground The harmfulness of sinking. In addition because in covering a roof with straw soil 9, sneak into the metal system with good heat conductivity Small pieces 10, so the heat energy of heat release pipe 2 can very pass to watts 8 effectively, can be effectively Melt accumulated snow.

The Roof thawing contructure of record is except the small pieces 10 of metal system in the claim 2, Also be provided with copper coin 11, so the heat energy of heat release pipe 2 can more efficiently be delivered to watts 8, Can carry out more effective snow melt operation.

Also have in first and second invention, can not produce because utilizing underground heat energy equally The problem of the environment such as atmosphere pollution.
