    • A sleeve heater is made by first cutting in one face of a flat metal plate a continuous groove and then fitting to the groove a heater wire with at least one end of the wire projecting past an edge of the plate. The plate is then plastically deformed with the wire to a tubular shape centered on an axis with the one face directed radially inward. The installation on a body to be heated is completed by fitting the deformed plate over the body to be heated and tightening the plate on the body to grip it snugly. The plate is formed of a heat-conducting metal, for instance brass, copper, or aluminum. The face of the plate from which the wire projects is directed radially inward so the wire directly engages the body. The tightener, which can be a band that circumferentially surrounds the sleeve or fittings provided at edges of the sleeve, bridges edges of the plate.
    • 套筒加热器是通过首先在平坦的金属板的一个面上切割一个连续的凹槽,然后将该金属丝的至少一端突出穿过该板的边缘而与槽相配合的加热丝。 然后,该板随着电线塑性变形成一个以轴为中心的管状,其中一个面朝向径向向内。 通过将变形的板安装在待加热的主体上并将板固定在身体上以紧贴地夹紧待加热的身体上的安装。 该板由导热金属形成,例如黄铜,铜或铝。 钢丝网的表面径向向内突出,使钢丝直接接合主体。 紧固件可以是周向围绕套筒的带或设置在套筒边缘处的接头,桥接板的边缘。
