Electrical connectors, fluid state testing devices and fluid heat exchange systems

Abstract

The invention discloses an electrical connector. The electrical connector includes a main body, a connection part, a first temperature-sensing element and a second temperature-sensing element, wherein: the connection part electrically connects the main body with a charging element arranged in a flow channel; The main body includes a first side and a second side parallel to the flow direction of the fluid, and the first temperature sensing element and the second temperature sensing element are respectively arranged on the first side and the second side opposite to each other in an electrically insulating manner. The invention also discloses a fluid state testing device and a fluid heat exchange system with electrical connectors. The electrical connector, fluid state testing device and fluid heat exchange system of the present invention can realize measurement and monitoring of fluid flow rate; measurement and monitoring of fluid pressure; measurement and monitoring of fluid resistance; measurement and monitoring without affecting the fluid flow field At least one purpose of the lateral vibration frequency of the electrical connector and suppressing the longitudinal vibration and / or lateral vibration of the electrical connector.

Description

technical field [0001] The invention relates to the technical field of electrical engineering, in particular to an electrical connector, a fluid state testing device and a fluid heat exchange system. Background technique [0002] Electric heating tube (or metal tubular electric heating element) is a charged element used to convert electric energy into heat energy. Compared with traditional heating, it is non-polluting, easy to install, easy to use, cheap, and belongs to environmental protection and green production, so it is widely used. It can be applied to a variety of equipment that requires heat exchange treatment. For example, multiple electric heating tubes can be used to form a heat exchange system, which can be installed in saltpeter tanks, water tanks, oil tanks, acid-base tanks, fusible metal melting furnaces, air heating furnaces, drying In the fluid passage of equipment such as furnaces, drying ovens, and hot pressing molds. [0003] When a plurality of electric...

AI Technical Summary

Problems solved by technology

When the insulated soft wire connection is used as the electrical connector to connect the electrodes of the electric heating tube, in order to avoid the resonance phenomenon of the wire in the fluid under the action of the fluid pressure, the insulated wire needs to be fixed on the inner wall of the fluid channel, and when the insulation of the wire After the insulation between the layer and the metal inner wall of the fluid channel fails, it will cause the electrical connector to discharge, resulting in a short circuit failure problem in the entire heat exchange system
