Description

Technical Field

[0001] The utility model relates to a heat dissipation installation structure of a control panel of an electric heater. Background Art

[0002] The electrical control box is the primary component for controlling an electric heater and is typically connected directly to the side of the heat radiating assembly. Existing control panels within the electrical control box typically dissipate heat through the installation of heat sinks, both of which are located within the electrical control box. To minimize heat from the heater's heat radiating assembly entering the electrical control box and protect it from the effects of the heat radiating assembly's temperature, the electrical control box is typically tightly sealed. This compromises the control panel's inherent heat dissipation and complicates its installation. Utility Model Content

DETAILED DESCRIPTION

[0020] To make the above features and advantages of the present invention more clearly understood, embodiments are given below with reference to the accompanying drawings for detailed description, but the present invention is not limited thereto.

[0021] refer to Figure 1 and Figure 2

[0022] A heat dissipation installation structure for an electric heater control panel includes an electric control box 2 for installation on one side of a heat radiation component of the electric heater, a control panel 1 installed in the electric control box, and a thyristor 3 installed on the control panel. The thyristor is attached to and fixedly connected to the bottom plate of the electric control box so that the thyristor conducts heat to the box body of the electric control box, and then dissipates heat outward through the box body of the electric control box, thereby improving the heat dissipation effect.

[0023] In this embodiment, a thickened seat plate 22 connected to the electrical control box is provided on the bottom plate of the electrical control box. Bolt holes 31 are provided on the connecting plate of the thyristor and are fixedly connected to the thickened seat plate by screws. Thermal grease is applied between the bottom surface of the thyristor and the thickened seat plate to improve the thermal conductivity.

[0024] In this embodiment, in order to better install the control panel, vertical support columns 4 are connected to the four sides of the control panel by screws. The support columns are plastic column tubes. The lower ends of the support columns are fixedly connected to the bottom plate of the electric control box by screws.

[0025] In this embodiment, the electrical control box comprises a grooved lower housing 23 and a grooved upper cover 24. The lower and upper covers interlock and are connected integrally via sealing plates 25 at either end. Both ends of the lower and upper covers are provided with threaded holes 26, which are screwed into the sealing plates to achieve locking. Both the lower and upper covers are made of aluminum (aluminum alloy).

[0026] In this embodiment, in order to improve the sealing effect and reduce the influence of the external temperature on the components in the electronic control box, sealing strips 27 are provided between the mating interfaces of the two side plates of the lower box body and the two side plates of the upper cover body, and sealing gaskets 28 are provided between the inner side surfaces of the sealing plates and the lower box body and the upper cover body.

[0027] In this embodiment, a translucent cover plate 5 is embedded in the upper side surface of the upper cover body, and a display element is provided on the control panel so as to display information such as numerical values ​​on the control panel outwardly through the translucent cover plate.

[0028] In this embodiment, mounting holes 21 are provided on both sides of the lower portion of the lower housing for the connecting rod 7 to pass through. The connecting rod passes through the mounting holes and is locked at its end with a bolt to connect the control box to the connecting rod. The other end of the connecting rod is used to connect to the heat radiation assembly.

[0029] In this embodiment, a power line threading tube 6 is installed on the bottom surface of the electric control box, that is, the bottom surface of the lower box body, to facilitate the insertion of the power line.

[0030] In this embodiment, the thickened base plate is arranged on the bottom plate of the lower box body and is integrally formed. In order to better install the thyristor, the thickened base plate is provided with a transverse protrusion extending to one side.

[0031] If the present invention discloses or involves components or structural parts that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connection using bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the mutual fixed connection can also be replaced by an integrated structure (for example, manufactured by integral molding using a casting process) (except where it is obviously not possible to use an integrated molding process).

[0032] In addition, unless otherwise stated, the terms used in any technical solution disclosed in the above-mentioned utility model to express positional relationships or shapes include states or shapes that are approximate, similar or close thereto.

[0033] Any component provided by the present invention can be assembled from multiple separate components, or can be a separate component manufactured by an integral forming process.
