Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and embodiments.

The present disclosure relates to a graphene-based uniform heating stone plate, as shown in fig. 1 to 5, including a stone plate body 1, a graphene heating layer 2, and a heat conduction layer 3. The stone slab body 1 may be various stone materials for a ground or a wall, preferably marble or granite.

The graphene heating layer 2 comprises a plurality of graphene heating strips 21 coated on the back surface 11 of the stone plate body 1, and the plurality of graphene heating strips 21 are uniformly arranged at intervals; then 1 back of stone slab body divide into bar graphite alkene district and the blank area of bar, and in order to ensure stone slab heating performance, the total area in the district that generates heat of bar graphite alkene is not less than the half of the 10 total areas in back, then the total area in the blank area of bar is less than the half of the 10 total areas in back. Preferably, the ratio of the strip-shaped graphene heating area to the strip-shaped blank area is 7:5-8: 4. Two ends of the graphene heating layer 2 corresponding to each graphene heating bar 21 are respectively connected with a positive electrode electric connection end 41 and a negative electrode electric connection end 42. The graphene heating strips 21 can be heated by current.

The heat conducting layer 3 is arranged on the graphene heating layer 2 and covers the back of the whole stone plate body 1. The stone slab body 1 is a poor conductor of heat due to the stone material, the heat conduction speed is slow, the whole heat generation of the guide pillar stone slab is slow, and the heat utilization rate is not high. From this, the present case is carried out the optimal design, at first generates heat layer 21 with graphite alkene and designs to be strip interval setting, then reaches the purpose of saving graphite alkene material quantity by a wide margin, and the two is with the help of the heat-conducting layer 3 structure that the bottom set up, realizes coming the stone plate and does the effect of similar keeping in with the heat that the stone plate was not in time to conduct, later conducts heat to the stone plate body evenly through this heat-conducting layer 3, finally realizes the whole effect of conducting heat evenly and promotion heat utilization ratio of stone plate. The heat conducting plate also plays a role in facilitating the laying of products on floors or walls.

It should be noted here that there is a great difference between this novel technical scheme and the design that locates the heat-conducting layer between stone plate material body and graphite alkene layer 2 that generates heat. The heat conduction layer is clamped in the middle, the heat conduction mode is carried out in sequence from the graphene, the heat conduction layer and the stone plate, the stone plate is not a primary heat receiver, the problem of low speed of sequential heat conduction still exists, and the problem of uneven heating of the stone plate can be caused by uneven heating of the heat conduction plate. The present case adopts the design of putting at the bottom of 3 heat-conducting layers, and the heat-conduction mode is diversified, goes on in step from graphite alkene-stone plate material body/heat-conducting layer, still carries out heat-conducting layer-stone plate material body heat transfer, and what the heat-conducting layer played is that the bottom keeps apart surrounds and keeps in the effect of heat (similar heat preservation) and circuitous even heat transfer effect. The heat transfer design of the heat conduction layer-stone plate body is further optimized below, and the problem of uneven heating of the stone plate is well solved.

Preferably, a plurality of grooves 31 are formed on the inner side surface of the heat conduction layer 3, the plurality of grooves 31 are formed by a plurality of corresponding guide strips 32, and the plurality of graphene heating strips 21 are correspondingly accommodated in the plurality of grooves 31 in a one-to-one matching manner. So design makes heat-conducting layer 3 provide simple and easy counterpoint composite action on the slabstone material body on the one hand. More mainly, heat-conducting layer 3 extends to simultaneously with graphite alkene layer 2 and stone plate body 1 looks in close contact with from the bottom surface, so the heat that graphite alkene layer 2 produced, wherein can't reach the heat-conducting layer 3 of heat transfer for stone plate body 1 in the heat that does not conduct, through the effective circuitous of the gib block 32 of heat-conducting layer 3, the bar blank that passes to stone plate body 1 is changeed, reaches the whole even effect of being heated of stone plate.

Further, the top surface of each guide strip 32 extends to form an embedded heat transfer part 33, and the back surface 11 of the stone slab body 1 is concavely provided with a plurality of embedding grooves 12 for matching and embedding the embedded heat transfer parts 33. So through the embedding of matcing each other of embedding groove 12 and embedded heat transfer portion 33, the area of contact of reasonable increase heat-conducting layer 3 and stone plate body 1 cooperates embedded half-surrounding form, makes the heat transfer efficiency between heat-conducting layer 3 and stone plate body 1 better, further promotes the heat conduction validity of heat-conducting layer 3 performance, promotes the whole homogeneity of being heated of stone plate body 1. In the embodiment, the embedded heat transfer portion 33 is a strip-shaped structure corresponding to the entire top surface of the guide strip 32, and the embedded groove 12 is a corresponding strip-shaped structure. Of course, the embedded heat transfer portion 33 may also be a plurality of convex structures designed intermittently, such as a plurality of embedded heat transfer beads designed at intervals, and a plurality of ball grooves designed at intervals corresponding to the embedding grooves 12.

In addition, the total notch area of the embedding grooves 12 is not more than one half of the area of the back surface 11 of the stone slab body 1, and the groove depth of the embedding grooves 12 is not more than one half of the thickness of the stone slab body 1. Thus, the embedding groove 12 can play a good role of heat transfer, and simultaneously, the structural strength and the stability of the stone plate body 1 are ensured.
