Abstract: PURPOSE: To facilitate maintenance for a heat exchanger or other component parts by providing a contact type temperature sensor for stopping a heater to prevent overheat of a temperature sensitive part on the outside of a jacket casing and in the heat transferring state to the heat exchanger. CONSTITUTION: A contact type temperature sensor 12 functioning as a temperature safety device is arranged on the outer surface of a jacket casing 7 near a closed end of a heat exchanger 5. A projection 13 is formed in an arrangement area for the contact type temperature sensor 12 of the heat exchanger 5, and a projection 14 is formed on the opposite side to form a direct contact part between the jacket casing 7 and the heat exchanger 5. Thus, the contact type temperature sensor 12 and the heat exchanger 5 are connected to each other to be thermally conductive. The sensor 12 is connected to a control device by lines 15, 16. This arrangement simplifies the constitution for heater protection.

Abstract: PURPOSE: To reduce a repair cost and an exchange cost, by a method wherein a support member is removably coupled to a support body for an absorbing body of which a part of the wall of an ignition chamber consists and an ignition device is arranged at the support member. CONSTITUTION: In a vaporizing type burner 1, a support body 4 for an absorbing body 5 is formed in the shape of a pot and provided with a bottom 6. A part of an ignition chamber 9 consists of an outer peripheral part 8 of a support body 4, and the opposite side to the bottom 6 of the support body 4 is closed by a support member 10 for an ignition device 11, and the support member 10 is removably coupled to the support body 4 and a burner chamber 3. A rodform glow plug 12 and a flame monitoring device 16 is mounted as the ignition device 11 on the support member 10. A seal 17 prevents liquid fuel from outflow to the outside through a gap between the burner chamber 3 and the support body 4. This constitution relieves a problem on a seal and exchanges the ignition device and the flame monitoring device regardless of the support body and irrelevantly exchanges the absorbing body and the support body, and reduces repair and maintenance costs.

Abstract: PURPOSE: To provide a heater for an automobile capable of rapidly supplying a heat into a vehicle by avoiding a dangerous heat transfer medium state like a steam bubble generation. CONSTITUTION: The heater for an automobile comprises a heat transfer medium circuit 9. The medium includes an at least one heat exchanger 14 attached with a vehicle heating fan 15, a heating unit 11 operated by fuel, a circulating pump 10 and a temperature sensor 17. A rotational speed of the pump is controlled by a controller 18 depending upon the medium temperature detected by the sensor. When the medium temperature is raised in at least a partial range of the heating operation, the controller 18 controls the speed of the pump 10 in response to the set temperature raising speed (temperature change per unit time) as a target value as compared with the actual value detected through the sensor 17.

Abstract: PURPOSE: To raise temperature smoothly and quickly by controlling the heater of an automobile to operate under at least two load states thereby facilitating heat dissipation from the heater. CONSTITUTION: A heat exchanging medium being used functions as a reference input which is the water temperature in case of a water heater. A temperature sensor 4 measuring water temperature θhas an output connected with the input of a trigger 3 incorporating an A/D converter. Circuit threshold value is referred through a logical module 2 and a controller 1 controls the heater depending on a recorded response. A resistor 5 is a compensation resistor for the temperature sensor 4. Output end of the controller 1 is connected with an actuator 6 in order to trigger starting at a combustion air fan 7. The heater is started constantly during partial load operation PL and a larger thermal request occurs during heat conduction cycle through introduction of another temperature threshold. When the temperature drops below the switching threshold, switching is made from partial load operation PL to full load operation PL.

Abstract: PURPOSE: To simplify the assembling of a controller and electric connection unit connected thereto, by providing a controller mounting space directly formed on a jacket-like outer casing for mounting a circuit board of the controller and sensor element on a heater. CONSTITUTION: A liq. heat exchange medium flows via a space 2 between a heat exchanger 3 and jacket-like outer casing 4. Outside the casing 4 a mounting space 8 is formed and controller 11 is mounted in this space 8. The controller 11 has one or more circuit boards and involves a sensor unit composed of a plurality of sensor elements 12, 13 which are mounted on the bottom wall 9 of the space 8. Semiconductor power components 14 are mounted on the side wall 10 of the space 8. An electric connection unit 20 connects an input and output 18 of the controller 11 to each operating part. Conductive components and contact components for connection between the input and output 18 are inserted in a plug-like board 23 attached to the unit 20.

Abstract: PURPOSE: To prevent deformation at the time of fixing equipment to a recessed wall in a cabin by disposing a press-in member in a through hole of the fixed equipment in a fixing device for a preselected measuring instrument or the like for an auxiliary heating device for a vehicle. CONSTITUTION: Equipment 1 such as a preselected measuring instrument for an auxiliary heating device for a vehicle is fitted to a fixed face 2 curved in recessed shape of a dashboard. This equipment 1 is provided with press-fit bush 4 formed of synthetic resin, in a through hole 3, and a fixing screw 5 is inserted with play through the bush 4 to bring a head 6 into contact with the front edge of the bush 4 to fasten. The outer peripheral surface 8 of the press-fit bush 4 has protrusions 9 formed in tooth shape and arranged in such a way as to act reversely to the fastening direction of the fixing screw 5. The equipment 1 can therefore be fixed to a recessed wall in a cabin without being deformed.
