Embodiment 1

[0022] A modular high-efficiency heat tracing pipe provided in this example, the cross-sectional schematic diagram is as follows figure 1 . In this embodiment, the heat tracing pipe 2 is a square pipe, and one end of the heat tracing pipe 2 matches the shape of the heated part 1. The thermal conductivity of the thermally conductive material is greater than 10W / (m·K). According to the physical properties of the heat tracing medium, operating conditions, and environmental conditions, one or more heat tracing pipes are fixed on the heat tracing pipe to ensure that the heat tracing meets the process requirements.

[0023] In the existing external heat tracing, there is air between the heat tracing pipe 2 and the heated part 1, and the heat transfer is mainly by air convection, and the heat transfer efficiency is low. In this embodiment, the heat tracing pipe 2 matches the shape of the heated part 1, and the soft heat conducting material filled in the joint can squeeze out the ai...

Abstract

The invention discloses a modular efficient heat tracing pipe. The modular efficient heat tracing pipe comprises a heat tracing pipe, a heat medium and a binding face, wherein the upper side face of the heat tracing pipe is the binding face, a soft heat conduction material is arranged on the binding face, and the heat medium is arranged in the heat tracing pipe. According to the modular efficientheat tracing pipe, the contact mode of the modular efficient heat tracing pipe and a heat-traced piece is surface contact, the gap between the heat tracing pipe and the heat-traced piece is further reduced through the soft heat conduction material, the heat tracing area is large, the heat transfer efficiency is high, and the heat tracing efficiency of the heat tracing pipe is greatly improved.

Description

technical field [0001] The invention relates to the field of heat tracing engineering, in particular to a modular high-efficiency heat tracing pipe. Background technique [0002] Heat tracing is an indirect heating method used outside or inside the pipe to prevent the fluid in the pipe from condensing, producing condensate or increasing viscosity due to temperature drop, and to keep the temperature of the fluid in the pipe stable. The common forms are external heat tracing and jacketed pipe tracing. hot. External heat tracing, also known as parallel steam tube heat tracing, is to install one or more steam tracing round tubes on the heated parts, which is the most widely used form at present, but due to the existence of thermal expansion, the heat traced parts and the traced parts There is usually a certain gap between the heat pipes, the heat transfer area is small, the heat transfer method is mainly air convection and heat radiation, and the heat transfer efficiency is low...
