Heat transfer probe comprises probe body with oppositely wound strands with one forming header strand with input lead and one forming return strand with output lead as funnel-shaped spiral set inside input spiral

摘要

The heat transfer probe comprises a cylindrical probe body (2) adjoined by a probe funnel (3). The probe body is formed from a pipeline (12) with winding arcs forming two oppositely wound strands (4,5) of which one is the header strand (4) and the other is the return strand and both are off-set from one another at a predetermined distance (a) and the header strand has the input lead (8) and the return strand has the output lead (9).The input lead is formed as a funnel shaped wound spiral (10) in the probe funnel and runs to the subsequently cylindrical header strand which winds downwards as a spool. The output lead is a funnel-shaped spiral (11) leading from the cylindrical upwardly wound return strand whereby this output spiral is set inside the input spiral at a distance to form a common funnel cover (17). The probe is made on a special winding machine by using a combined funnel-core template.
