Abstract
A heater plate manufactured by receiving a sheath heater within a groove portion formed in a base member made of aluminum or aluminum alloy, placing a joint member made of aluminum or aluminum alloy into said groove portion so as to fix said sheath heater in the groove portion, and press-forging said base member and said joint member to be metal-bonded with said sheath heater fixed in place therebetween, wherein a cross section of said joint member comprises a rectangle, and a width of said rectangle is same as or a little larger than a width of a cross section of the groove portion.
Claims32
A heater plate manufactured by receiving a sheath heater within a groove portion formed in a base member made of aluminum or aluminum alloy, placing a joint member made of aluminum or aluminum alloy into said groove portion so as to fix said sheath heater in the groove portion, and press-forging said base member and said joint member to be metal-bonded wit said sheath heater fixed in place therebetween,
- wherein a cross section of said joint member comprises a rectangle with a flat bottom face or a curved concaved bottom face, radius of said curved concaved bottom face is larger than radius of an outer periphery of said sheath heater, and a width of said rectangle is larger than a width of a cross section of the groove portion.
A method for manufacturing a heat plate comprising:
- receiving a sheath heater within a groove portion formed in a base member made of aluminum or aluminum alloy,
- placing at least on joint member made of aluminum or aluminum alloy into said groove portion so as to fix said sheath heater in the groove portion;
- and
- press-forging said base member and said joint member to metal joint same with said sheath heater fixed in place therebetween,
- wherein a cross section of said joint member comprises a rectangle with a flat bottom face or a curved concaved bottom face, radius of said curved concaved bottom face is larger than radius of an outer periphery of said sheath heater, and a width of said rectangle is larger than a width of a cross section of the groove portion.
