摘要： The present invention relates to a motor comprising: a motor housing; a stator which is provided in the motor housing and has a coil; a rotor installed in the stator to be rotatable about a rotary shaft; and a spray hole which is formed in the circumferential surface of the rotor by passing through the circumferential surface in a radial direction and which sprays a cooling fluid in the motor housing onto the coil according to the rotation of the rotor. Therefore, cooling by oil convection can be accelerated while minimizing resistance due to the oil.

摘要： Disclosed herein is a motor including a motor assembly. The motor assembly has a stator to rotate a rotor being coupled to a shaft, a housing including an inner space to receive the motor assembly, a first flow path and a second flow path. The first flow path provided at least in part outside the stator to allow first fluid to flow in the first flow path, and to discharge into the inner space for cooling the stator and the rotor. The second flow path provided at least in part between the first flow path and the stator to allow second fluid to flow in the second flow path and to absorb heat of the stator transferred through a flow path wall.

摘要： A ventilation apparatus includes a casing having the inside partitioned into a first floor and a second floor. A first sharing duct is formed in the first floor and configured to suck one of indoor air and outdoor air and to have the sucked air horizontally moved. A second sharing duct is formed in the second floor and configured to suck the other of indoor air and outdoor air and to have the sucked air horizontally moved. First and second heat exchangers are disposed in the first and second sharing ducts, respectively The ventilation apparatus is advantageous in that air resistance is minimized, horizontally moving air is subject to heat exchange with the entire area of the heat exchanger, and efficiency of heat exchange between air and the heat exchanger is improved because air is divided into the first floor and the second floor and horizontally moved.
摘要翻译：通风设备包括壳体，该壳体具有分隔成第一地板和第二地板的内部。第一共享管道形成在第一层中，并被配置为吸入室内空气和室外空气中的一种并使吸入的空气水平移动。第二共用导管形成在第二层中，并被构造成吸入室内空气和室外空气中的另一个，并使吸入的空气水平地移动。第一和第二热交换器分别设置在第一和第二共用导管中。通风设备的优点在于，空气阻力最小化，水平移动的空气与热交换器的整个区域进行热交换，并且热交换效率空气和热交换器之间的空气被分成一楼和二楼并水平移动，从而改善了空气和热交换器之间的连接。
