Embodiment Construction

[0027] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. The examples are only used to explain the present invention, not to limit the protection scope of the present invention.

[0028] (1) The structure of the heat dissipation bridge

[0029] see figure 1 , figure 2 and image 3 , The heat dissipation bridge provided by the present invention includes an upper heat transfer plate 1 , a lower heat transfer plate 2 and a special-shaped heat transfer tube 3 . The inner diameter (i.e. lumen diameter) of the special-shaped heat transfer tube 3 is compatible with the diameter of the heating cable (slightly larger than the diameter of the heating cable), so that the heating cable passes through the lumen of the special-shaped heat transfer tube when laying, and keeps A certain degree of close contact. The outer contour of the radial section of the special-shaped heat transfer tube 3 includes two heat ...

Abstract

The invention discloses an anti-freezing electric heating heat dissipation bridge for a channel in a cold region. The heat dissipation bridge comprises an upper heat transfer plate, a lower heat transfer plate and a special-shaped heat transfer pipe which are made of aluminum alloy. The lower heat transfer plate is fixed to the wall of the channel, a heating cable is placed in the special-shaped heat transfer pipe, heat generated by the heating cable is conducted to the upper heat transfer plate and the lower heat transfer plate through the special-shaped heat transfer pipe, and the purpose ofmelting ice is achieved. The heat dissipation bridge can solve the problems that the heating cable is poor in heat transfer and small in temperature influence range, and the water delivery time of the channel in winter is prolonged.

Description

technical field [0001] The invention relates to a heat conduction device of a canal water delivery project, in particular to a heat dissipation device applied to a canal anti-freezing heating cable. Background technique [0002] Long-distance water transmission projects are the most effective and direct means to solve the problem of uneven temporal and spatial distribution of water resources. When the cold weather comes in winter, the water body continues to exchange heat with the atmosphere and lose heat, and the water in the channel gradually becomes supercooled. Ice flowers of different sizes. In winter, on both sides of the channel, for example, the water flow at the concave bank of the curved section is relatively slow, and the thermal conductivity of the lining plate is larger than that of the water body, so ice flakes tend to accumulate in these places to form primary shore ice, and then the ice develops from both sides of the channel to the middle, forming For ice ...
