Embodiment Construction

[0033] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0034] The purpose of the heat exchanger performance test of the present invention is to simulate the working conditions of the tested heat exchanger test piece, and detect whether its heat transfer capacity and resistance meet the design requirements; the second is to obtain different types and The performance curve data of the specification fins, the establishment and enrichment of the fin performance database. In order to have a better, higher and more economical design level. The specific plan is as follows.

[0035] refer to figure 1 , which includes the air circulation system with air as the fluid medium, the oil circulation system with oil as the fluid medium, the water / ethylene glycol circulation system with water or eth...

Abstract

The invention discloses a heat exchanger performance test-bed, which comprises an air circulation system, an oil circulation system, a water / ethylene glycol circulation system and a compressed air system that are respectively connected with a test piece. The heat exchanger performance test-bed of the invention, on the one hand, simulates the working condition of the tested heat exchanger test piece so as to test whether the heat transfer capacity and the resistance are qualified for the design regulation requirements, on the other hand, by testing the standard test piece, the performance curvedata of fins which have different types and specifications is obtained, and the fin performance database is established and enriched, thereby the design can reach a better, higher and more economicallevel.

Description

technical field [0001] The invention relates to a detection device, more precisely a heat exchanger performance test bench. Background technique [0002] The heat exchanger is a device that transfers part of the heat of the hot fluid to the cold fluid. The heat exchanger is widely used, such as radiator fins for heating in daily life, condensers in steam turbine devices, and oil coolers on space rockets, etc. , are heat exchangers. It is also widely used in industrial sectors such as chemical industry, petroleum, power and atomic energy. Its main function is to ensure the specific temperature required by the process for the medium, and it is also one of the main equipment to improve energy utilization. [0003] The degree of metal fatigue is due to the uneven internal structure of the metal, which causes the imbalance of stress transmission, and some places will become stress concentration areas. At the same time, there are many tiny cracks at the defects inside the metal...
