Embodiment Construction

[0018] Figures 1 to 4 Each schematically shows the structure of a generator with cooler according to the present invention. As shown in the figure, the generator 10 includes a frame 16 for accommodating a stator and a rotor (not shown), a cooler 11 connected to the frame 16 , and a base 17 for supporting the frame 16 and the cooler 11 . like figure 2 and 3 As shown in , the cooler 11 includes a cooling pipe 14, an air outlet 12 connected to one end of the cooling pipe 14 and a fan 15 arranged in the air outlet 12, wherein the fan 15 is used to promote the flow of gas through the cooling pipe 14 to enhance cooling Function. The fan 15 includes, for example, blades 152 and a motor 151 for driving the blades. The rotor and the stator (not shown) are arranged in the frame 16 along the X direction, and the cooling pipes 14 in the cooler 11 are arranged along the Y direction which is substantially perpendicular to the X direction. like image 3 As shown, the hot air in the b...

Abstract

The invention provides a generator with a cooler. The generator includes a generator base for accommodating a stator and a rotor, which are arranged in a first direction; and a cooler arranged on the generator base. The generator is characterized in that the cooler includes a plurality of cooling tubes arranged in a second direction which is basically vertical to the first direction and an air outlet port which is arranged at one end of the cooling tubes and provided with an air fan, wherein at the side of the other ends of the cooling tubes, the distance for which the cooler extends out of the base in the second direction does not exceed about 10% of the width of the base. The invention also provides a motor with a similar structure.

Description

technical field [0001] The present invention relates to electric motors or generators, and more particularly to a motor or generator with a cooler. Background technique [0002] The motor or generator generates heat due to internal loss during operation, so a cooling medium is required to cool its windings and iron core to maintain the temperature of each part within the allowable limit. [0003] Typically, conventional heat exchangers are used to cool the airflow inside the frame of a motor or generator, thereby cooling the windings and core. However, traditional heat exchangers are weak in enhancing the airflow inside the frame and on the other hand are large in size, which is not conducive to the application where space is limited, such as the case of applying such generators to wind turbines . Contents of the invention [0004] Aiming at the above-mentioned technical problems, the present invention proposes a generator or motor with an improved cooler, which includes...
