  • Publication number: 20200025428
    Abstract: A heat exchanger includes: heat transfer tubes aligned with one another; a header connected to end portions of the heat transfer tubes; and fins joined to the heat transfer tubes. When viewed in a longitudinal direction of the header and when the heat exchanger is used as an evaporator, the header is divided into: a circulation space including a first space in which refrigerant flows in a first direction along the longitudinal direction of the header and a second space in which the refrigerant flows in a second direction opposite to the first direction along the longitudinal direction; and an insertion space into which the heat transfer tubes are inserted. The header includes: a circulation division plate that divides the first space from the second space; and an insertion space forming plate that divides the circulation space from the insertion space.

  • Patent number: 10520256
    Abstract: A heat exchanger includes a plurality of principal heat exchange sections and auxiliary heat exchange sections. Each of the auxiliary heat exchange sections is in series connection to a corresponding one of the principal heat exchange sections. Tube number ratios of the principal heat exchange sections are obtained by dividing the number of the flat tubes constituting each of the principal heat exchange sections to by the number of the flat tubes constituting a corresponding one of the auxiliary heat exchange sections. Of the principal heat exchange sections, the first principal heat exchange section, which is the lowermost one, has the smallest tube number ratio. Consequently, discharge of liquid refrigerant from a lower portion of the first principal heat exchange section is accelerated during defrosting, thereby shortening the time required for defrosting.

  • Patent number: 4667072
    Abstract: A protrusion is formed downstream of the throat of an insulating nozzle of a gas-insulated circuit breaker of puffer type. Quenching gas, after collision with the protrusion, is blown against an arc generated between a fixed arcing contact and a moving arcing contact in the opening process of the gas-insulated circuit breaker. As a result, a pressure drop at or near the forward end (Q) of the fixed arcing contact can be prevented thereby to improve the insulation strength in the opening process.

  • Patent number: 4211903
    Abstract: An electromagnetic puffer type gas circuit breaker comprises two opposing puffer type gas circuit breaking units mounted on midway support means, actuating means for driving the circuit breaking units, an electromagnetic actuating unit drivingly coupled to the actuating means, and current transfer mechanism for transferring and applying the interrupting current to the electromagnetic actuating unit during a circuit breaking operation. The current transfer mechanism is located, in operative connection to the actuating means, at a point above the midway support means and in a spaced relation to the electromagnetic actuating unit. The contact surface area of the current-conducting path portion leading to the transfer mechanism is a fraction of that of another current-conducting path portion for the passage of most of the rated current. These features provide ease of inspection and replacement of the current transfer mechanism and reduces the operating force requirement of the breaker.
