Experimental purpose:
1. Measure the heat transfer of fin-tube heat pipe heat exchanger and analyze the relationship between the temperature of the hot end medium.
2. Experiments can be conducted on the influence of the inclination angle of the heat pipe on the working performance of the heat pipe.
M*n configuration:
fin-tube heat pipe heat exchanger, heating section circulating heating *r duct, heated section heating *r duct, blower, circulating fan, flute flowmeter with differential pressure sensor , heating is steplessly adjusted by solid pressure regulating module, signal input inspection instrument displays temperature and pressure difference, ammeter, voltmeter, st*nless steel stand and control panel, etc.
Technical parameters:
1. Input power: single-phase AC220V±10% 50Hz, power 500W.
2. Low noise centrifugal fan, power: 250W, flow rate: 1000 m3/h.
3. Pitot tube flowmeter with inclined tube micromanometer to measure flow rate: range -10-700pa.
4. The diameter of the cold and hot end speed measuring section *r duct is Φ100mm, and the hot section *r adopts a circulation system, and the system temperature rises quickly; the finned (aluminum rolled sheet tube) heat pipe heat exchanger has a size of Φ20 × 420mm and is made of copper tube.
5. Temperature measurement: The measurement system is equipped with an intelligent temperature control instrument (PID temperature control, accuracy ±0.2℃), and a high-precision PID voltage regulation module circuit.
6. Dimensions: 1500×550×1600mm, with a st*nless steel movable bracket and double brake wheels.
7. The virtual simulation software for electrical installation of building buildings and intelligent buildings
is based on unity3d design. Users can choose different sizes of interactive interfaces according to computer configurations, and can choose six levels of image quality. The model in the software can be rotated 360°, enlarged, reduced, and translated. There are assistant prompts during the use of the software, the contents are as follows:
