Definitions

  • the invention relates to a motor vehicle preheater. Background technique
  • a typical engine preheating unit with a circulating pump consists of three independent parts: a heating chamber, a pump, and a motor. These three parts are generally arranged in the order of the heating cavity, pump, motor or pump, heating cavity, and motor along the direction of the motor shaft, such as ZL99223027. 6, ZL98240295. 3
  • the disadvantage of this type of device is that the device is relatively large, It is more difficult to install on a motor vehicle.
  • An object of the present invention is to provide an engine preheater. Its volume is much smaller than existing similar devices, and it can be installed on motor vehicles more conveniently.
  • the device includes a housing, an impeller, a motor, an electric heating element, and the like.
  • the shell is a sealed cavity, and the shell has a water inlet and a water outlet, and the shell
  • the inner-cavity of the chamber is through water inlet: _ and —out — water — mouth and start freezing: phase ⁇ electric rotation.
  • F L fixed: lost core _ coil, motor shaft and other components.
  • the motor is inside a motor casing, which is part of the casing.
  • the rotor and the motor shaft are in the rotor case, and the engine coolant can flow into the rotor case.
  • the motor case and the rotor case together separate the stator core and the coil from the engine coolant.
  • the impeller is mounted on the motor shaft. The parts are arranged in the order of the water inlet, impeller, motor, electric heating element, and water outlet in the direction of the motor shaft.
  • the impeller is directly facing the water inlet and forms a centrifugal pump structure with the inner wall of the casing near the water inlet and the motor casing. There is a space between the motor casing and the inner wall of the casing in the direction of the motor shaft diameter. Water that is pumped into the casing from the water inlet through the impeller can flow from this space into the space where the electric heating element is located.
  • the shape of the motor stator is U-shaped or concave, the stator has two magnetic poles, and the rotor is made of permanent magnet material. Due to the above scheme, the volume of the preheater can be greatly reduced, and it can be installed on a motor vehicle very conveniently. When the motor is operating, the rotor and the motor shaft are enclosed in the engine coolant by the rotor shell, so the coolant will not leak. To the outside of the case. BRIEF DESCRIPTION OF THE DRAWINGS
  • Figure 1 is a schematic structural diagram of an engine preheater
  • Fig. 2 is a sectional view taken along line A-A in Fig. 1.
  • the impeller 5 is between the water inlet 1 and the motor casing 4, the motor is between the impeller 5 and the electric heating element 12, and the electric heating element 12 is between the motor casing 4 and the outlet. Between the nozzles 1, the parts are aligned in the direction of the motor shaft 8.
  • the impeller 5 pumps the engine coolant into the casing 3, and the engine-liquid is driven to the electric heating element 12 through the space between the motor casing 4 and the inner wall of the casing 3.
  • Water outlet 2 flows out.
  • the electric heating element 12 is an electric heating tube with a power of 1500W
  • the stator core 10 is formed by superimposing steel sheet punches

Abstract

L'invention concerne un préchauffeur de moteur pour véhicule utilisé avant l'allumage à froid du moteur. Ledit préchauffeur de moteur emploie une source de courant électrique domestique traditionnelle et permet de chauffer l'antigel du moteur au moyen d'une pompe centrifuge et d'un dispositif de chauffage électrique qui se trouvent dans ledit préchauffeur. Ce dernier comprend un logement au niveau duquel sont disposées une entrée et une sortie d'eau, une pompe, un moteur électrique et un dispositif de chauffage électrique. Cette pompe directement opposé à l'entrée d'eau et le logement sont conçus sous forme d'une pompe centrifuge. Le préchauffeur de moteur peut être facilement installé sur le véhicule en raison de sa petite structure.
