Patent JP-S5924141-A (JP)
Title: Heat exchanger
Inventor: SUGANO TADAO
IPC: F28F1/40
Filed: 1982-07-29
Abstract: PURPOSE:To maintain perfect combustion, lengthen the life thereof and obtain the heat exchanger of small size, highly efficient and low cost by a method wherein a plurality of fins are provided in the heat exchanger, a hollow radiating body is arranged along the vicinity of a wall surface at the upstream side of combustion gas in the heat exchanger and a space is provided between the radiating body and the inner wall surface of the heat exchanger. CONSTITUTION:A combustion fan in a burner 1 and a solenoid pump 11 are driven and fuel is supplied into the burner 1, then, the fuel is ignited to form a combustion flame 2 and maintain the combustion. High temperature combustion gas, generated in the heat exchanger 3, transmits a part of the heat thereof to the radiating body 6 to heat the radiating body 6 red some times, however, when the gas arrives at the external fins 5 of the heat exchanger 3 through the space 6', the temperature of the gas arrives at the temperature of 200-300 deg.C when it arrives at the external fins 5. Next, the heat of the high temperature combustion gas is exchanged at the surfaces of a plurality of inner fins 4 by baffles A7, B8 and the gas is released to the outside of the exchanger through an exhaust tube 9. When a fan 10 for convection is started in this process by a thermostat or the like provided at a part in an instrument, airflow is generated and the air is contacted with the surfaces of the heat exchanger 3 and the external fins 5 and heat exchange is effected between the air and the combustion gas in the heat exchanger 3.

Abstract: PURPOSE:To reduce conductor resistance, and to improve the adhesive strength of the conductor resistor by a method wherein the silver grains of the conductor paste, with which an end part conductor pattern will be formed, have the grain diameter larger than that of the silver grains of the conductor paste with which the conductor pattern in the internal part will be formed. CONSTITUTION:An end part conductor pattern 11 is printed on a magnetic layer 10. The conductor paste used for the above-mentioned end part conductor pattern 11, is formed by adding a binder to silver grains, and the silver grains having the grain diameter of about 10mum are used. Then, a magnetic layer 20 is printed leaving the end part of the conductor pattern 11, and a conductor pattern 21 is formed in such a manner that the tip of about a half turn component is extended to above the magnetic layer 20 overlapping the tip part of the conductor pattern 11. The silver grains of the conductor paste, which forms the above-mentioned conductor pattern 21 and having the three kinds of grain diameters of 0.01mum, 0.1mum and 1.0mum, is used. As a result, the evaporation of silver can be prevented, voids are hardly generated on the edge part of the conductor pattern, and the increase in conductor resistance can be prevented.
