Detailed Description

In order to make the technical problem, technical solution and advantageous effects to be solved by the present invention more clearly understood, the following description is given in conjunction with the accompanying drawings and embodiments to illustrate the present invention in further detail. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1 and 2, an electric heating heat exchange device, including braced frame 1, heat exchange tube 2 and heat transfer fin 3, braced frame 1 is last to install many heat exchange tubes 2, heat exchange tube 2 is from top to bottom and comes and goes the structural arrangement, still install a plurality of heat transfer fins 3 on heat exchange tube 2, heat transfer fin 3 is located braced frame 1, the top water inlet of one of them part heat exchange tube 2 is connected with inlet distribution pipe 4, the top delivery port of another part heat exchange tube 2 is connected with outlet collecting pipe 5, the bottom of heat exchange tube 2 all is connected with collector pipe 6, inlet distribution pipe 4, outlet collecting pipe 5 and collector pipe 6 all set up the outside at braced frame 1, install inlet manifold 7 on the inlet distribution pipe 4, install outlet manifold 8 on the outlet collecting pipe 5.

The supporting frame 1 is mainly formed by surrounding four supporting plates 9, through holes for the heat exchange tubes to penetrate through are formed in the supporting plates on the two sides of the heat exchange fins 3 and the supporting frame 1, and the heat exchange tubes 2 are in interference fit with the heat exchange fins 3.

The utility model discloses when using, this electric heating heat transfer device immerses in heat transfer medium, makes heat transfer fin 3 and heat exchange tube 2 soak completely in heat transfer medium, can effectually make heat transfer medium and intraductal water carry out the heat exchange, improves heat exchange efficiency. The water inlet main pipe 7 enters one part of heat exchange pipes through the water inlet distribution pipe 4, then enters the other part of heat exchange pipes 2 through the water collecting pipe 6, and flows out of the water outlet collecting pipe 5 after heat exchange.
