Temperature measuring system for thermal hydraulic test of wound tube heat exchanger

The invention relates to the technical field of winding pipe heat exchangers, and discloses a winding pipe heat exchanger thermotechnical hydraulic test temperature measuring system, a plurality of temperature measuring devices comprise temperature measuring bases with one ends fixed to different areas of the outer wall surface of a winding pipe heat exchanger body, and the other ends are in threaded connection with an internal thread section; a gasket is arranged between the temperature measuring base and the internal thread section to achieve hard sealing, a hole is formed in the temperature measuring base, one end of the guide pipe penetrates through the hole and extends to an inner cavity of the winding pipe heat exchanger body, the other end of the guide pipe penetrates through the gasket and the internal thread section and extends to the outside, and a thermocouple is arranged in the guide pipe. The measuring point pipe supporting piece is fixed to the inner wall face of the inner cavity and used for fi
