Description

Heat conduction mechanism for cooling generator

Technical Field

The utility model relates to the field of heat pipes, in particular to a heat conduction mechanism for cooling a generator.

Background

The heat pipe technology has been widely used in aerospace, military industry, radiator manufacturing and other industries since 1963 is born. The heat pipe fully utilizes the conduction principle and the rapid heat transfer property of the phase change medium, and the heat of the heating object is rapidly transferred to the outside of the heat source through the heat pipe, so that the heat conduction capacity of the heat pipe exceeds the heat conduction capacity of any known metal. The typical heat pipe consists of a pipe shell, a liquid absorption core and a phase change medium, wherein the pipe is pumped into negative pressure of 1.3 Pa (10-1 to 10-4) and then is filled with a proper amount of working liquid, so that the liquid absorption core capillary porous material closely attached to the inner wall of the pipe is filled with the liquid and then is sealed. One end of the heat pipe is an evaporation section (heating section), the other end is a condensation section (cooling section), and a heat insulation section can be arranged between the two sections according to application requirements. When the evaporation section of the heat pipe is heated, the working liquid in the pipe core is heated and evaporated, and heat is taken away, the heat is the evaporation latent heat of the working liquid, the steam flows from the central channel to the condensation section of the heat pipe, is condensed into liquid, and simultaneously releases the latent heat, and the liquid flows back to the evaporation section under the action of capillary force. This cycle is not complete, and a large amount of heat is transferred from the heating section to the cooling section. In the prior art, the case of applying the heat pipe technology to cooling and radiating of the motor is mainly divided into forced air cooling based on the heat pipe and forced water cooling based on the heat pipe. Forced air cooling effect based on the heat pipe is good, but the motor structure is large in size due to air cooling requirement, so that miniaturization is not facilitated; meanwhile, the arrangement position of the heat pipe is not ideal, basically the heat pipe is arranged on the shell or the iron core yoke part, and the heat pipe is not directly arranged in the iron core groove with relatively concentrated heat or directly takes away the heat generated by the main heat source in the middle of the groove, so the cooling effect is not very obvious. The forced water cooling effect based on the heat pipe is better, the motor shell and the independent water cooling circulation system are connected by the heat pipe, the position of the heat pipe is not positioned at the main heat source but on the shell, and the forced water cooling system and the motor main body are separated, so that the arrangement is that the cooling effect is better than the forced air cooling effect, but the conduction heat dissipation is not the most direct and the most effective; meanwhile, the forced water cooling system is separated from the motor main body, so that the development trend of high integration of the current motor design is not met, and unnecessary design and installation space are increased.

Therefore, it is necessary to provide a heat conduction mechanism for cooling a generator and a generator using the same, which are used for directly cooling the inside of the motor to generate a main heat source in a stator groove or in the middle of the groove, so as to solve the most fundamental cooling and heat dissipation problem of the motor.

When the evaporation section 101a of the heat pipe is heated, the working liquid in the pipe core is heated and evaporated, and takes away heat, the heat is the evaporation latent heat of the working liquid, the steam flows from the central channel to the condensation section 101c of the heat pipe, is condensed into liquid, and simultaneously releases the latent heat, and the liquid flows back to the evaporation section 101a under the action of capillary force. This cycle is not complete, and a large amount of heat is efficiently transferred from the heating section to the cooling section. The external shape of the heat pipe 101 employed in the present utility model is specially treated.

The condensing section 101c is inserted into the water channel of the cooling mechanism 300 through the hole on the sealing post 304; the insulating section 101b is interposed between the end windings and the seal post to facilitate vapor communication and condensate wicking. The evaporation section 101a is flat for the purpose of: firstly, the contact area between the winding and the winding is increased, and the heat absorption and evaporation are fully carried out; secondly, the degree of fit with the winding is increased, so that the winding is convenient to be tightly fit; thirdly, the space between windings is reduced, and the space utilization rate is increased.

Further, the cooling system includes a heat pipe assembly 100 and a cooling mechanism 300. The evaporation section 101a of the heat pipe assembly 100 absorbs heat generated directly in the whole tank or in the middle of the tank, the phase-change medium evaporates to form steam, the steam flows from the central channel to the condensation section 101c of the heat pipe under the action of air pressure, and circulating water in the cooling mechanism 300 performs a convection heat exchange effect on the condensation section 101c, so that the steam is condensed into liquid in the condensation section 101c, and the liquid flows to the evaporation section 101a under the action of capillary force of the liquid absorption core, so that the circulation is not completed.

The evaporation section 101a of the heat conduction assembly penetrates through the whole groove and is positioned between the end windings at two sides, so that the range of conduction heat can be ensured to the greatest extent, and the heat of the main heat source is continuously transferred to the condensation section 101c under the action of the heat pipe 101. The cooling mechanism 300 pumps cooling water with a certain temperature from the water inlet under the pumping action, then the cooling water flows through the condensation sections 101c uniformly distributed in the circumferential direction in the circulating water channel to perform the heat convection action, thereby taking away heat, finally the water with heat is pumped out from the water outlet 203c, the water is brought to the outside for cooling, and the cooled water is pumped in from the water inlet 203 b. Such a cycle is not complete. Because the cooling system is used for cooling the part which is the inner stator part with the most serious heat generation, the cooling effect is the most obvious and the most direct.
