Thermal performance detection device of heat exchanger

Abstract

The invention provides a thermal performance detection device of a heat exchanger. The thermal performance detection device comprises a heat flow generator assembly, signal harnesses, a computer controller, a heat exchanger test board assembly, pipe opening connectors, a waste heat recoverer assembly and power lines. Each pipe opening connector is a device, wherein the pipe diameter at the two ends of the pipe opening connector can be adjusted; the heat flow generator assembly and the heat exchanger test board assembly transmit signals with the computer controller through the signal harnesses; the heat flow generator assembly processes external air into gas phase heat fluid at certain temperature and flow speed under the instruction of the computer controller and then guides the heat fluid to the heat exchanger test board assembly, the heat exchanger test board assembly measures the temperature of a test region on the outer wall of a heat exchanger and the flow speed of the internal air flow, sends the temperature and the flow speed to the computer controller in the mode of signals and gives out an evaluation result, and finally remaining heat flow enters the waste heat recoverer assembly for being recovered. The thermal performance detection device detects the thermal performance of the heat exchanger quite well and has the advantages of being clean, environmentally friendly, safe, efficient, economical, durable and the like.

Description

technical field [0001] The invention relates to the field of heat exchanger detection devices, in particular to a heat exchanger thermal performance detection device which integrates functions such as self-generated hot gas fluid, temperature measurement and flow velocity, and waste heat recovery. Background technique [0002] Today, the depletion of fuel energy makes the development of new energy and energy recovery and reuse more and more important. The heat exchanger is a device for exchanging heat between hot and cold fluids, which can be used to recover the waste heat of the hot fluid. Also widely used as heaters, coolers and condensers. Thermal performance testing of heat exchangers is an important link in the design, development and quality control of heat exchanger products. The performance and evaluation methods of existing thermal performance testing devices for heat exchangers are not perfect enough, and there is a problem of high energy consumption. Waste heat i...
