Abstract

The invention discloses a device for testing thermal performance and fluid resistance of a liquid-liquid heat exchanger. The device is characterized in that a heat source medium container consists of a high-temperature container and a low-temperature container, which are arranged separately; heat source medium outlet pipelines of the high-temperature container and the low-temperature container are respectively connected with a heat source three-way regulating valve; a heat source variable frequency pump is arranged in the heat source medium outlet pipeline of the heat source three-way regulating valve; the outlet pipeline of the heat source variable frequency pump is connected to the heat source medium inlet of the tested heat exchanger; a steam heat exchanging unit is arranged in the heat source medium outlet pipeline of the tested heat exchanger; the heat source medium subjected to heat exchange in the tested heat exchanger is heated by the steam heat exchanging unit, and flows backto the high-temperature container; and an auxiliary electric heater is arranged in the high-temperature container. The device can realize fast detection and adjustment, effectively and stably controlthe temperature fluctuations of cooling and heat sources and reduce the error of a testing system.

Description

technical field

[0001] The invention relates to a liquid-liquid heat exchanger thermal performance and fluid resistance testing device, more specifically for liquid-liquid heat exchangers (such as Shell-and-tube heat exchangers, plate heat exchangers, spiral plate heat exchangers, etc.) are test devices for thermal performance and fluid resistance testing. Background technique

[0002] The energy saving of heat exchanger products is a key task in the energy saving work of high energy consumption special equipment, and the energy saving evaluation indicators are complex and difficult. The test device is mainly used for the detection of heat transfer performance and resistance drop of heat exchanger products. The determination of thermal performance and fluid resistance of heat exchangers provides an important basis for the development of high-efficiency and energy-saving products and the inspection of product quality characteristics.

[0003] At present, industrial test dev...
