IPC: F25B39/04
Filed: 1996-04-17
Abstract: PROBLEM TO BE SOLVED: To facilitate insertion in a header pipe from an ordinary direction by a method wherein the part, communicating with an outlet pipe, of a liquid receiving part is arranged at a header pipe in a direction extending substantially vertically to the direction of insertion of a heat-exchange tube in a header pipe. SOLUTION: A liquid receiving part 13, especially a communication part with an outlet pipe 9 thereof, is arranged in a direction extending substantially vertically to a heat-exchange tube insertion direction. Thereby, a partition plate 11 is inserted in the header pipe 3 from a direction reverse to a tube insertion direction. The insertion direction is an ordinary insertion direction of a type incorporating no liquid receiving part 13. Thus, regardless of a liquid receiving part built-in type, a hole for a partition plate insertion is formed in a header pipe 3 part through a method similar to an ordinary method. The partition plate 11 is easily inserted through the hole and joining by brazing after insertion is practicable.

Filed: 1986-05-27
Abstract: PURPOSE:To securely detect the temperature abnormality of a connection part by detecting partial electrostatic discharging which is caused continuously between a main circuit conductor and a shield cover through the operation of a temperature fuse. CONSTITUTION:The temperature fuse 30 is supported through a support metallic fitting 32 on an insulating base 31 fitted at a position on the main circuit conductor 1 nearby a connector 1a, one terminal of the fuse 30 is connected to the shield cover 24 through a lead 8, and the other terminal is connected to the main circuit conductor 1 through a clamping screw 33. The fuse 30 operates above constant temperature corresponding to the specific temperature at the contacting position between, for example, the connector 1 and contacting piece 2 to enter a break state. In such break state, partial discharge is caused on the surface of an insulator 10 and continues for a long time without forming any conductive layer on the surface of the insulator because the fuse 30 is in the break state and the insulator 10 uses an organic insulator such as heat- resisting ceramic, so that this discharging is detected.

When the instruction 3 is received in the standby system, an internal switching circuit 5 synchronizes with a frame pulse 8 for operation control and controls an output of an internal switching signal 12 that is for state switching of a self-system. An external switching circuit 6 receives the instruction 3 and outputs a switching request signal 11 to the other system, i.e., the current system. A delay circuit 7 is provided on an output side of the circuit 6. The circuit 7 monitors an input of the pulse 8 upon receiving the instruction 3 and delays an output of the signal 11 by the circuit 6 until the next frame pulse is received.
