[embodiment]
Now in conjunction with the accompanying drawings the present invention is described further.
Referring to Fig. 1, comprise flameproof cabinet, heat exchange of heat pipe, central dividing plate, flameproof cabinet inner heat source, the heat pipe 1 that heat exchange of heat pipe is mainly arranged by array passes the stacked fin that is provided with central dividing plate 6 and forms; Flameproof cabinet 8 upper surfaces are established an opening flange, heat exchange of heat pipe central dividing plate 6 one sides are that heating section 3 is located in the flameproof cabinet 8, heat exchange of heat pipe central dividing plate 6 opposite sides are that cooling section 2 is located at outside the flameproof cabinet 8, heating section 3 absorbs the heat of casing inner space, cooling section 2 absorbs heat with institute and dissipates by fin, and central dividing plate 6 adopts bolt on the opening flange.
Central dividing plate 6 adopts corrosion resistant plates, and thickness is 10～25mm, which is provided with the heat pipe installing hole, and the heat pipe installing hole is a step T type through hole, and the axis of installing hole and central dividing plate 6 are β=60 °～90 ° at an angle; Heat pipe 1 with central dividing plate 6 interference fit, and adopts scolding tin that heat pipe 1 and dividing plate 6 are welded to connect by the heat pipe installing hole.
The heating section 3 of heat exchange of heat pipe adopts the forced convertion mode to carry out heat exchange, and cooling section 4 adopts free convection or forced convertion mode to carry out heat exchange; Side board 5 is established in cooling section 2 left and right sides of heat exchange of heat pipe, and the top of cooling section is provided with top cover plate 4, and side board 5 and top cover plate 4 have formed a kind of passage for fluid flow during fluid flow.
