Versatile encapsulated fluid heater configuration

摘要

A fluid heater for heating fluid at high pressure may comprise a containment vessel with a base portion having a primary face with a peripheral surface section having a substantially frusta-conical shape. The vessel may comprise an elongated main portion having a perimeter wall with a thickness and terminating with a base edge surface. The base edge surface may have a substantially frusta-conical shape such that the base edge surface and the peripheral surface section collectively form a weld receiving groove. A width of the peripheral surface section of the primary face of the base portion may be greater than the thickness of the perimeter wall of the main portion.

主权项

1. An electrically powered fluid heater for heating fluid at high pressure, comprising:
a containment vessel for defining a chamber, the containment vessel comprising:
a base portion having a primary face with a central surface section and a peripheral surface section extending about the central surface section, the peripheral surface section having a substantially frusto-conical shape; andan elongated main portion with a closed outward end and an open base end for mounting to the base portion, the main portion having a substantially cylindrical perimeter wall extending from the base end toward the outward end, the perimeter wall having a thickness and terminating at the base end of the main portion with a base edge surface, the base edge surface having a substantially frusto-conical shape such that the base edge surface and the peripheral surface section collectively form a weld receiving groove;wherein a width of the peripheral surface section of the primary face of the base portion is greater than the thickness of the perimeter wall of the main portion; and at least one heating element mounted on the base portion and extending into the heating chamber.
