Embodiment Construction

[0025] The present invention will be described in further detail below.

[0026] A heat pipe type winding enhanced heat dissipation motor adopts the existing permanent magnet synchronous motor structure, including a shaft and its fixing parts, two end covers, a water-cooled casing, a stator core, a stator winding, a rotor and magnetic steel, bearings, two A group of heat pipes, two heat pipe pressure tube plates. The rotor and magnetic steel are fixed on the shaft and its fixing parts. Bearings are installed between the shaft and its fixing parts and the end cover. The end covers are fixed on both ends of the water-cooled casing. And the magnetic steel is arranged sequentially from the outside to the inside.

[0027] The length of the stator core is shorter than that of the stator winding and the water-cooled casing, so that two annular cavities are formed between the three, and the electronic potting compound is filled in the cavities.

[0028] A plurality of pipe grooves a...

Abstract

The invention relates to a heat pipe type winding enhanced heat motor which comprises two end covers and the following elements that are arranged in sequence from the outer part to the inner part: a water-cooling machine housing, a stator core, a stator winding, a rotor and magnetic steel. The two end covers are arranged at the two ends of the water-cooling machine housing. Two annular accommodation cavities are formed among the end part of the stator winding, the stator core, and the water cooling machine housing. The invention also comprises two sets of heat pipes with each one set corresponding to one accommodation cavity. The accommodation cavities are filled with electron casting glue. One end of each heat pipe is embedded into the end cover while the other end extends into the cavity and is sealed in the electron casting glue. The motor of the invention is simple in structure and is convenient to manufacture. Capable of rapidly guiding heat of out the end part of a stator winding, the thermal conduction efficiency is improved. The motor of the invention belongs to the technical field of new energy automobiles.

Description

technical field [0001] The invention relates to the field of new energy automobiles, in particular to a motor that utilizes a heat pipe to conduct heat generated at the end of a motor stator winding to an end cover, and then transfers the heat from the end cover to a water-cooled casing for heat dissipation. Background technique [0002] Vigorously developing new energy vehicles is a strategic measure to promote the transformation and upgrading of the automobile industry and build an environment-friendly society. Drive motor is the core component of new energy vehicles, and its performance has a direct and important impact on new energy vehicles. Motor operating temperature directly affects motor efficiency, reliability and service life. Excessive temperature rise will accelerate the aging of the motor insulation material and shorten the service life; the efficiency of the motor will decrease, resulting in an increase in heat generation and further pushing up the temperatur...
