The invention relates to the technical field of electric heaters, in particular to a high-strength pressure-resistant electric heater, comprising a base, a heating tube, a plug, an insulating base, a conductive block, a contact block, a spring, a guide pin, a connector, and two ends of the base. A vertical plate is provided, the heating pipe is overlapped on the vertical plate, the plug is arranged on the vertical plate, and the insulating base is connected to the vertical plate; the conductive block is arranged in the insulating seat, and the plug is fixedly connected with the conductive block. The present invention is provided with a conductive block, a contact block and a spring. When the heating pipe is subjected to a lateral extrusion force, the spring can avoid the lateral extrusion force and improve the compression resistance of the heating pipe. At the same time, the conductive block, the contact block and the spring are all conductive materials. The heating tube is always electrically connected to the plug, and the guide pin keeps the heating tube in a horizontal state to prevent the heating tube from rotating. Fins, positioning sleeves, and locking rings are provided. When the heating tube is subjected to longitudinal pressure, the locking ring can Longitudinal pressure is circumvented by sliding inside the tapered bore.
Description
technical field [0001] The invention relates to the technical field of electric heaters, in particular to a high-strength pressure-resistant electric heater. Background technique [0002] Electric heater is an internationally popular electric heating equipment. It is used for heating, heat preservation and heating of flowing liquid and gaseous medium. When the heating medium passes through the heating chamber of the electric heater under pressure, the principle of fluid thermodynamics is used to uniformly take away the huge heat generated by the electric heating element during work, so that the temperature of the heated medium meets the user's process requirements. [0003] When assembling or installing the existing electric heaters for air conditioners, it is often difficult to assemble due to manufacturing errors. During assembly, the heating tube will be bent and deformed, which will easily cause damage to the heating tube over time. Contents of the invention [0004]...
