Problems solved by technology

[0006] The purpose of the present invention is to address the deficiencies of the prior art, by setting the contact between the cooling medium and the hot gas, to achieve rapid cooling, and after cooling, use the cooling medium to discharge the cooling cycle, and at the same time realize the cooling after the cooling medium is discharged. On the other hand, every time the forklift is repaired, the side of the cooling medium carrier that is in contact with the high-temperature hot gas is automatically replaced synchronously, thereby improving the service life of the device, thus solving the problem of the forklift during driving. The speed of the vehicle causes the heat emitted by the heat dissipation element to be useless, and then through the same heat dissipation method and degree, the technical problem is that the heat dissipation effect is poor

Abstract

The invention relates to a rapid heat dissipation method for a forklift control system. The rapid heat dissipation method comprises the steps that 1, a cooling medium is introduced; 2, hot air coolingis conducted; 3, the flow speed of the cooling medium is adjusted automatically and is synchronous with the second step; 4, air is released; and 5, an alarm is given. The rapid heat dissipation method solves the technical problems that in the driving process of a forklift, heat emitted by a heat dissipation element is not used due to different forklift speeds, and consequently the heat dissipation effect is poor through the same heat dissipation manner and degree.

Description

technical field [0001] The invention relates to the technical field of forklifts, in particular to a rapid heat dissipation method for a control system of a forklift. Background technique [0002] The temperature control of the electric counterbalanced forklift controller plays a vital role in the performance of the forklift. If the controller cannot dissipate heat sufficiently, it will seriously affect the performance of the forklift. When the temperature of the controller exceeds a certain set temperature, the maximum current will decrease proportionally with the increase of temperature. When overheating, the controller reduces the output torque by cutting the current. [0003] When the electric counterbalanced forklift works without stopping for a long time, especially when it is fully loaded and climbing, the temperature of the controller will rise rapidly. When the convection cooling type or contact cooling cannot dissipate the generated heat, the controller will work...
