Abstract
Disclosed in the utility model is an electric heating panel of a buffet furnace. The electric heating panel comprises an aluminium casting heater, an aluminium plate upper cover, and an aluminium plate lower cover. The aluminium casting heater is formed by a cuboid casting aluminium, a U-shaped heating wire with a connector lug, two leads, and high temperature-resistant insulation tube sleeves; the U-shaped heating wire with a connector lug is embedded and casted inside the cuboid casting aluminium; the two ends of the connector lug of the U-shaped heating wire are welded with the two leads by an argon arc welding way; and the welding positions are coated by the high temperature-resistant insulation tube sleeves. The aluminium casting heater is arranged in the aluminium plate upper cover and the aluminium plate lower cover and is particularly contacted with the aluminium plate lower cover tightly, wherein the gap is less than 0.1 millimeter. Because of utilization of the argon arc welding mode, the welding positions where the two leads and the connector lug of the heating wire do not break easily, the disconnection phenomenon can be avoided. Moreover, the welding positions are coated by the high temperature-resistant insulation tube sleeves, thereby avoiding the short circuit phenomenon.
Description
Technical field
The utility model relates to a kind of electric heater unit, relates in particular to a kind of electrical heating board of buffet furnace.
Background technology
In cast aluminum heaters commonly used; what the welding of heater strip and wire adopted is the mode of arc welding; this welding manner is the heat that utilizes arc discharge (being commonly called as arc burning) to produce by the fusing form weld seam after condensation mutually of welding rod and workpiece; thereby obtain the welding process of firm joint; do not adopt any isolated air measure; easily oxidation; and cause not prison welding solid; permanent use can cause the phenomenon opened circuit; weld does not in the past have the protection of high-temperature insulation cover yet, and phenomenon easily is short-circuited.
The utility model content
The purpose of this utility model is for solving the problems of the technologies described above, and a kind of electrical heating board of buffet furnace is provided, and the utility model adopts argon arc welding, improved welding manner, be difficult for breaking phenomena occurs, weld has increased the high-temperature insulation cover, is difficult for the phenomenon that is short-circuited.
The technical scheme that the utility model adopts is:
A kind of electrical heating board of buffet furnace, comprise cast aluminum heaters, aluminium sheet upper cover, aluminium sheet lower cover, described cast aluminum heaters is by the cuboid cast aluminium, form with ' u ' shape electrical heating wire of connector lug, two wires, high-temperature insulation pipe boxes, described ' u ' with connector lug shape electrical heating wire castingin is in cuboid cast aluminium inside, connector lug two ends and two wire bonds of described ' u ' with connector lug shape heater strip, described cast aluminum heaters is located in aluminium sheet upper cover and aluminium sheet lower cover.
Further, connector lug two ends and two wires with ' u ' shape electrical heating wire of connector lug adopt the mode of argon arc weldings to weld.
Further, with connector lug two ends and two wire bonds places of ' u ' shape electrical heating wire of connector lug, by the high-temperature insulation pipe box, wrapped up.
Further, cast aluminum heaters is close to the aluminium sheet lower cover, and gap is less than 10.
The beneficial effects of the utility model are:
1.breaking phenomena, can not occur in two wires and be difficult for disconnecting with the connector lug weld of ' u ' heater strip of connector lug.
High-temperature insulation pipe box parcel for weld, phenomenon can not be short-circuited.
3. heating effect is good, and energy transformation ratio is high.
The accompanying drawing explanation
Fig. 1 is a kind of electrical heating board of buffet furnace structure chart.
Embodiment
As shown in Figure 1: a kind of electrical heating board of buffet furnace, comprise cast aluminum heaters 1, aluminium sheet upper cover 2, aluminium sheet lower cover 3, cast aluminum heaters is by cuboid cast aluminium 4, form with ' u ' shape heater strip 5 of connector lug, two wires 6, high-temperature insulation pipe boxes 7, described ' u ' with connector lug shape heater strip 5 castingins are in cuboid cast aluminium 4 inside, the connector lug two ends of described ' u ' with connector lug shape electrical heating wire 5 and two wire 6 welding, described cast aluminum heaters 1 is located in aluminium sheet upper cover 2 and aluminium sheet lower cover 3.Connector lug two ends and two wires 6 with ' u ' shape heater strip 5 of connector lug adopt the mode of argon arc weldings to weld.With the connector lug two ends of ' u ' shape heater strip 5 of connector lug and two wire 6 welds by high-temperature insulation pipe box 7 parcels.Cast aluminum heaters 1 is close to aluminium sheet lower cover 3, and gap is less than 10.
Operation principle of the present utility model is: after two wires of electrical heating board of buffet furnace and external power source are connected, heater strip first generates heat, and then heat is passed to the cuboid cast aluminium, and the cuboid cast aluminium passes to lower cover by heat, the lower cover heating, then buffet furnace just can heat.
Claims (4)
1. an electrical heating board of buffet furnace, comprise cast aluminum heaters, aluminium sheet upper cover, aluminium sheet lower cover, it is characterized in that: described cast aluminum heaters is by the cuboid cast aluminium, form with ' u ' shape electrical heating wire of connector lug, two wires, high-temperature insulation pipe boxes, described ' u ' with connector lug shape heater strip castingin is in cuboid cast aluminium inside, connector lug two ends and two wire bonds of described ' u ' with connector lug shape heater strip, described cast aluminum heaters is located in aluminium sheet upper cover and aluminium sheet lower cover.
