LED (light-emitting diode) street lamp low temperature environment aging room

Abstract

The invention discloses an LED (light-emitting diode) street lamp low temperature environment aging room. The LED street lamp low temperature environment aging room comprises an aging room body, an air-circulating channel which is used for continually circulating to introduce cold air to an aging region in the aging room body, a controller and multiple temperature-detecting devices, wherein the air-circulating channel comprises a low temperature exchanger, a low temperature compressor, a fan, a cold air inlet channel, and an air return channel, wherein the low temperature exchanger is arranged above the middle of the aging room body, the low temperature compressor is connected with a low temperature exchanger, the cold air inlet channel is used for leading cooling draft acquired by the low temperature exchanger after low temperature exchange to successively introduce the aging region through multiple cold air inlets, the air return channel is used for absorbing air in the aging region under the action of the fan to the side of the low temperature exchanger so as to carry out low temperature exchange through multiple air return ports, and the cold air inlet channel is communicated with the air return channel through a communicating pipe. The low temperature environment aging room provided by the invention has the advantages of simple structure, is easy to operate, is low in cost and has good using effects, and can be used for effectively solving a temperature maldistribution problem in the aging region through adjusting the refrigeration states of the low temperature exchanger and the low temperature compressor and the shutter states of air inlets and the air return ports.

Description

Technical field [0001] The invention relates to a low-temperature aging room, in particular to an LED street lamp low-temperature environment aging room. Background technique [0002] The burn-in room, also known as the burn-in room, is a simulation of high-performance electronic products (such as: complete computers, monitors, terminals, automotive electronics, power supplies, motherboards, monitors, and switching chargers, etc.) This kind of equipment with high temperature, low temperature and harsh test environment is an important experimental equipment to improve product stability and reliability. This equipment has been widely used in power electronics, computers, communications, biopharmaceuticals and other fields. The low-temperature aging test of electronic products is a necessary means to eliminate early failure of electronic products and control product quality. The uniformity of temperature distribution in the aging room is an important technical indicator of the agin...
