Active cooling type probe

Abstract

The invention discloses an active cooling type probe. The active cooling type probe comprises a current needle, a plastic seat and a voltage needle, wherein a first spring is fixedly arranged at one end of a side surface of the current needle, a round ventilation hole is formed in a middle part of an inner wall of the current needle, a positioning nut is fixedly arranged at a middle part of a surface of the plastic seat, the voltage needle is fixedly arranged above the positioning nut at the top of the plastic seat by a limitation nut, a second spring is movably arranged at a surface of one end, arranged in the plastic seat, of the voltage needle, and an L-shaped air pipe is fixedly arranged at an inner wall of the limitation nut at one end, far away from the plastic seat, of the voltage needle by a rapid connector. The air pipe is used and communicates with the ventilation hole by the rapid connector, external equipment employs a form of compressed air or vacuum negative pressure so that air in the probe is rapidly circulated, redundant heat in the probe is further taken way by air convection to achieve the purpose of active cooling, the service lifetime of the probe is prolonged,meanwhile, the accuracy of a detection result is ensured, and the active cooling type probe is high in practicability.

Description

technical field [0001] The invention relates to the technical field of battery testing equipment, in particular to an active heat dissipation probe. Background technique [0002] The development and application of lithium batteries only appeared in modern times, and the corresponding production equipment developed much later than other traditional industries. The mass production of power batteries has only started in recent years. In the process of production, it is necessary to When the battery is charged and discharged, a probe is used to make contact with the battery to be tested. When the existing probe passes a large current, it will generate a large amount of heat energy, which will not only affect the normal operation of the product, but also easily cause serious heating after long-term use, affecting the detection results, and has a safety risk. poor effect. Contents of the invention [0003] The purpose of the present invention is to provide an active heat dissi...
