Abstract
The utility model relates to a comb-shaped heater of a finger fork type, particularly a heater which uses PTC semiconductive ceramic material as a heating element. The utility model is composed of a bottom board (1), a PTC heating element (2), a right inserting sheet (3), a right inserting sheet (6) and a cover plate (8). The utility model is characterized in that a left electrode (4) and a right electrode (5) of the PTC heating element (2) are made into the comb shape and are crossed, such as the crossing of fingers of two hands. When the utility model is used, the left and the right inserting sheets (3, 6) are connected with a power supply, the current passes through the left and the right electrodes (4, 5), and the PTC element (2) generates heat. The utility model is suitable for devices with local heating requirements for household appliances and industries.
Description
The utility model relates to a kind of heating element, particularly is the heating element of heater element with the PTC semiconductor ceramic material.
Heating element at present of the same type, heater element adopt plate shaped, and as shown in Figure 3, its defective is that thermal resistance is higher, efficient is low, under equal power condition, and the Curie-point temperature height.
The purpose of this utility model is to provide a kind of thermal resistance little for overcoming above-mentioned defective, and the efficient height can reduce the heating element of Curie point under equal power condition.
The technical solution of the utility model is left and right sides electrode to be made pectination also pitch mutually, the PTC heater element of pitching mutually as two hand fingers is placed in the inner chamber of base plate, left and right sides electrode and the hole bottom base plate that left and right sides inserted sheet inserts the PTC heater element pass, after the inserted sheet energized of the left and right sides, the PTC element is promptly heatable.
The utility model has the advantages that novel structure, thermal resistance is little, the efficient height, and the reliability height with the temperature that can reduce Curie point under the constant power, has remarkable energy saving effect.
Description of drawings:

Fig. 2 is the A-A cutaway view of Fig. 1
Fig. 3 is the schematic diagram of prior art
Below in conjunction with accompanying drawing the utility model is further described, the utility model is made up of base plate (1), PTC heater element (2), left inserted sheet (3), right inserted sheet (6) and cover plate (8).PTC heater element (2) is placed on two boss (11) of inner chamber of base plate (1), left electrode (4) and the hole (10) bottom base plate (1) that left side inserted sheet (3) inserts PTC heater element (2) pass, and right electrode (5) and the hole (9) bottom base plate (1) that right inserted sheet (6) inserts PTC heater element (2) pass.Left side electrode (4) and right electrode (5) are made pectination and to fork, are pitched mutually as two hand fingers, and left electrode (4) and right electrode (5) are a little less than the last plane (7) of PTC heater element (2).During use, after left inserted sheet (3) and right inserted sheet (6) were connected with the mains, left electrode (4) and right electrode (5) promptly had electric current to pass through, and PTC heater element (2) will generate heat, and heat can spread out of from cover plate (8).
Claims (2)
1, a kind of pectination finger-fork type heating element, by base plate (1), heater element (2), left side inserted sheet (3), right inserted sheet (6), cover plate (8) are formed, the PTC heater element (2) that it is characterized in that making the pectination finger-fork type is placed on two boss (11) of inner chamber of base plate (1), left side inserted sheet (3) inserts the left electrode (4) of PTC heater element (2) and passes from the hole (10) of the bottom of base plate (1), and right inserted sheet (5) inserts the right electrode (5) of PTC heater element (2) and passes from the hole (9) of the bottom of base plate (1).
2, pectination finger-fork type heating element according to claim 1, the left electrode (4) that it is characterized in that the PTC heater element (2) of said pectination finger-fork type becomes pectination and relative fork to live with right electrode (5), pitch mutually as two hand fingers, left electrode (4) and right electrode (5) are a little less than the last plane (7) of PTC heater element (2).
