Operating life test system for wind power heat dissipation plate piece under extreme conditions

Abstract

The invention discloses an operating life test system for a wind power heat dissipation plate piece under extreme conditions. The operating life test system comprises a low-temperature water tank anda high-temperature water tank, wherein the low-temperature water tank is connected with inlets of a high pressure pump and a delivery pump respectively by means of a ball valve, outlets of the high pressure pump and the delivery pump are each connected with an inlet on one side of the heat dissipation plate piece by means of a pipeline, a pressure sensor is arranged between the outlet of the highpressure pump and the inlet on one side of the heat dissipation plate piece, an outlet on one side of the heat dissipation plate piece is connected with the low-temperature water tank by means of an electric ball valve, the high-temperature water tank is connected with inlets of a high pressure pump I and a delivery pump I respectively by means of a ball valve I, outlets of the high pressure pumpI and the delivery pump I are each connected with an inlet on the other side of the heat dissipation plate piece by means of a pipeline, a pressure sensor I is arranged between the outlet of the highpressure pump I and the inlet on the other side of the heat dissipation plate piece, and the outlet on the other side of the heat dissipation plate piece is connected with the high-temperature water tank by means of an electric ball valve 1. The operating life test system can test the operating life of the heat dissipation plate piece quickly and efficiently under extreme conditions.

Description

technical field [0001] The invention belongs to the field of radiators, and in particular relates to a working life test system for wind power cooling plates under extreme conditions. Background technique [0002] The cooling plate is the most important part of the cooler. It mainly cools the transmission friction heating parts such as the gearbox, so that the equipment can always be kept within a reasonable temperature range and can operate normally. Due to the harsh working conditions of the wind power cooling plate, The ambient temperature has a large temperature difference between day and night, and the medium temperature difference is also large during operation after the gearbox is shut down, and it needs to meet the use of different models of products. Once the heat dissipation plate fails, the gearbox and the entire fan equipment cannot work normally. In view of the heat dissipation plate The overall size of the fins is relatively large, and the maintenance hatch of ...

Problems solved by technology

[0003] Commonly used wind power cooling plates are made of aluminum alloy materials through high-temperature welding. In order to achieve a good heat dissipation effect, the cooling plates have various forms in the shape and fin structure design to meet the heat dissipation needs of various equipment. The difference in the design and welding process of different structures is related to the life of the cooling plate. However, due to the lack of necessary testing system for the sample, the working life of the wind power cooling plate cannot be verified, and only a single pressure pulse or withstand voltage test can be carried out. , or judged by the actual operation of the product after installation, so there is a greater risk
