Description

Technical Field

[0001] This utility model belongs to the field of heat exchanger technology, specifically relating to a stepless frequency conversion device for underfloor heating heat exchange. Background Technology

[0002] A plate heat exchanger is a high-efficiency heat exchanger composed of a series of corrugated metal plates stacked together. Thin rectangular channels are formed between the plates, through which heat exchange occurs. Plate heat exchangers are ideal for liquid-liquid and liquid-vapor heat exchange. They feature high heat exchange efficiency, low heat loss, compact and lightweight structure, small footprint, wide application, and long service life. Under the same pressure loss conditions, their heat transfer coefficient is 3-5 times higher than that of a tubular heat exchanger, their footprint is one-third that of a tubular heat exchanger, and their heat recovery rate can reach over 90%.

[0003] Existing stepless frequency conversion equipment for underfloor heating heat exchange still has some defects. Most of these equipment require the use of plate heat exchangers during operation. Plate heat exchangers do not have a filtration mechanism and cannot filter the incoming liquid. After long-term use, impurities accumulate in the plate heat exchangers, causing blockages. To address this, we propose a stepless frequency conversion equipment for underfloor heating heat exchange. Utility Model Content
