摘要:
There is disclosed a heater unit (1600) for conductively heating a removable heat exchanger unit (1602) via a heat transfer surface of the heat exchanger unit, the heater unit comprising: a body portion (1610) for receiving the heat exchanger unit (1602); a flexible heating element (1604) which, in use, makes thermal contact with the heat transfer surface of the heat exchanger unit; a compressible portion (1606) disposed on the distal side of the flexible heating element (1604) relative to the heat exchanger unit (1602) when received; and a biasing arrangement (1608) operable, in use, to distribute a transverse compression force across the arrangement formed from the compressible portion (1606), the heating element (1604) and the heat exchanger unit (1602), whereby the compression force causes the heating element (1604) to be urged towards the heat transfer surface of the heat exchanger unit (1602) and the compressible portion, in conjunction with the compression force, causes the heating element (1604) to conform more closely to the shape of the heat transfer surface.

摘要:
A system and method to control the electrical power input to direct electrically heated subsea pipelines. The system comprises a plurality of variable voltage generators and a plurality of step-up transformers. Each step-up transformer is electrically connected to the output of an associated generator. The system further comprises a plurality of variable step-down transformers. Each step-down transformer is electrically connected the output of the step-up transformers and to an associated pipeline segment.
摘要:
There is provided a fluid heating device for an engine with increased heating efficiency of fluid. The fluid heating device for an engine includes: a holder 1; a heater 2; and a radiator pipe 3, the radiator pipe 3 is inserted into the holder 1, the heater 2 is housed in the holder 1, heat of the heater 2 is radiated to fluid 4 passing through the radiator pipe 3 via the radiator pipe 3. The radiator pipe 3 is formed by an outer pipe 5 and an inner pipe 6 in the outer pipe 5, the heat generated by the heater 2 is transferred to the outer pipe 5 and the inner pipe 6, the fluid 4 passing inside and outside the inner pipe 6 in the outer pipe 5 is heated by heat radiation from the outer pipe 5 and the inner pipe 6.
摘要:
A variable power device for a uniform heating of fluids, comprising an outer tube (10), which is connected to a fitting or flange (14) for connecting the power supply and grounding cables (21) and to one or more fluid distribution connectors (24, 26), said outer tube (10) enclosing a first drilled heat sink (13), made of conductive material, within which a first hollow space (11) and a wire-type or layer-type resistor (12), embedded within an insulating layer, are inserted, In this way, the resistor (12) is not directly connected with the fluid, but it is directly connected with said first heat sink (13) and therefore it is possible to distribute heat from said first heat sink (13) to the fluid in correspondence with a large surface, while said first heat sink (13) also maintains a low temperature at the fluid contact surface.
