Abstract
The utility model provides a central air-conditioning unit shell tubular heat exchanger. The central air-conditioning unit shell tubular heat exchanger comprises a shell and an end cap. The end cap is provided with a refrigerating fluid liquid inlet and a refrigerating fluid liquid outlet. The shell is in the structure of a cylinder with one end opened. The shell is provided with a relief-hole plate. The shell is divided into a first cavity and a second cavity by the relief-hole plate. The end of the first cavity is provided with a water inlet tube. A copper tube bundle is arranged in the second cavity. Duo to the fact that the relief-hole plate is added in the water inlet, the local flow velocity is reduced and the impact to a copper tube is reduced. Meanwhile, the water inlet direction is changed into the direction parallel to the copper tube bundle from the direction perpendicular to the copper tube bundle, and therefore the fatigue deformation fracture of the copper tube caused by the way that water inlet flow directly and horizontally rushes to the copper tube is avoided. The refrigerating fluid liquid inlet is provided with a diffuser plate, and therefore the refrigerating fluid can enters into the end cap liquid inlet cavity evenly and the local heat transfer caused by the uneven distribution of the refrigerating fluid is avoided.
Description
Technical field
The utility model relates to a kind of central air-conditioning, particularly a kind of central air-conditioning unit shell and tube exchanger.
Background technology
Air-conditioning unit mesochite pipe heat exchanger mainly is comprised of end cap, heat exchanger main body and housing three parts, flows in the cavity of water between housing and copper pipe bundle, and cold-producing medium flows in copper pipe.During refrigeration, cold-producing medium absorbs water side heat in the inner evaporation of copper pipe after expansion valve dams, Air Conditioning Cycle water is freezed; When heating, the high temperature refrigerant gas after the compressed machine compression enters copper pipe through behind the four-way change-over valve, to water side release heat, and is condensed into liquid, thereby air-conditioner circulating water is heated.Present heat exchanger copper pipe is arranged accurate, and water inlet pipe is directly aimed at copper pipe Shu Jinshui, although compact conformation, volume is little, and is easy to wear if be subject to impact shock because the plumbers shed gap is little, and foreign material enter extremely difficult cleaning behind the copper pipe gap in the Air Conditioning Cycle water.
Summary of the invention
