Abstract
The utility model relates to a heating block for a tin spray tank, which comprises an electric heating wire. A groove is arranged inside a planar fiber block, the electric heating wire is arranged inside the groove, and the joint of the electric heating wire protrudes out of the fiber block. During usage, the electric heating wire facing toward the tin spray tank is exposed to directly heat the tin spray tank. The fiber block with the advantages of small heat conductivity coefficient, high temperature resistance and low liability of breakage can effectively prevent heat loss to the exterior of the tin spray tank, so as to improve heat utilization efficiency. The service life of the heating block is more than 6 months.
Description
Technical field
The utility model relates to a kind of heater, the heat block that particularly a kind of printed circuit board spray molten tin bath is used.
Background technology
The used heat block of existing printed circuit board spray molten tin bath is the ceramic heat piece, ceramic heat piece monoblock is to make the square shape of camber of pottery, be provided with heating wire in the square shape, square shape two ends are thicker, there is following shortcoming in it: (1) is because ceramic thermal conductivity factor is big, heat block is when heating, and the heat energy that heating wire produces is to the diffusion of heat conduction all around, and heat energy dissipation is bigger; (2) the curved shape of heat block profile is attached to spray molten tin bath outer wall during installation, have certain spacing with outer wall, and it is low also lower with the efficiency of heating surface to cause conducting thermal energy; (3) to produce fragility in being subjected to thermal process big, cracked easily for the ceramic heat piece, and service life was about only 7 days.
Summary of the invention
The purpose of this utility model just provides the spray molten tin bath heat block of a kind of heat energy utilization rate height, long service life.
The utility model can be realized in the following way: spray molten tin bath heat block, comprise heating wire, and be provided with groove in the fiber block on described plane, be provided with heating wire in the groove, end element conneccting is stretched out outside the fiber block.
Heating wire towards spray molten tin bath one side when the utility model uses exposes, directly the spray molten tin bath is heated, because the thermal conductivity factor of fiber block is low, and it is high temperature resistant, not easily broken, can effectively prevent heat energy lost heat energy outside the spray molten tin bath, thereby make heat energy utilization rate height, reach more than 6 months service life.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
In the drawings: fiber block 1, heating wire 2, groove 3.
The specific embodiment
Below in conjunction with embodiment, the utility model will be further described, but it is not represented as unique embodiment of the present utility model.
Please read Fig. 1, the fiber block 1 on plane is to cast in the mould after stirring according to a certain ratio with nano heat insulating material, nanometer micropore heat-insulating material, adhesive, curing agent, when being cast to preset height, heating wire 2 is placed on the default groove 3, the joint of heating wire 2 stretches out outside the fiber block 1, continues to be cast to and sets mold height after baking forms.Fiber block also can be made with existing thermal conductivity factor low, high temperature resistant, not easily broken other material and adhesive, curing agent.
When the utility model uses, the even distribution of heat block is close to four sides and the bottom that is installed in the spray molten tin bath, the joint of heating wire 2 is connected with the mains, heating wire 2 towards spray molten tin bath one side exposes, and directly the scolder in the spray molten tin bath is heated, because fiber block 1 thermal conductivity factor is little, and it is high temperature resistant, not easily broken, heat energy lost heat energy outside the spray molten tin bath be can effectively prevent, thereby heat energy utilization rate height, long service life made.
Claims (1)
1. a spray molten tin bath heat block comprises heating wire (2), it is characterized in that being provided with groove (3) in the fiber block (1) on plane, is provided with heating wire (2) in the groove (3), and the joint of heating wire (2) stretches out outside the fiber block (1).
