Embodiment Construction

[0036] In order to make the above objectives, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] The purpose of the heat exchanger performance test of the present invention is to simulate the working conditions of the test piece of the heat exchanger under test, and to detect whether its heat transfer capacity and resistance meet the design requirements; the other is to obtain different types of heat exchangers by testing standard test pieces. Establish and enrich the performance database of fins based on the performance curve data of specification fins. In order to have a better, higher and more economical design level. The specific plan is as follows.

[0038] Reference figure 1 , Which includes the air circulation system with air as the fluid medium for testing the performance of the heat exchanger test pi...

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 curve data 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 economical level.

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. Heat exchangers are widely used, such as heating radiators for heating in daily life, condensers in steam turbines, and oil coolers on space rockets, etc. , Are all heat exchangers. It is also widely used in the chemical, petroleum, power and atomic energy industries. Its main function is to ensure the specific temperature required by the medium in the process, and it is also one of the main equipment to improve energy utilization. [0003] Metal fatigue is due to the uneven internal structure of the metal, resulting in unbalanced stress transmission, and some places will become stress concentration areas. At the same time, there are many tiny cracks in the defects inside the metal. Under the continuous action of the force, the cr...
