Noise reduction air supply device for refrigerated display cabinet

Abstract

The invention relates to the technical field of refrigeration equipment, and discloses a noise reduction and air supply device for a refrigeration display cabinet, the noise reduction and air supply device comprises a goods shelf bottom box, an air inlet is formed in the top of one side of the goods shelf bottom box, an air supply duct is formed in the other side of the goods shelf bottom box, and a motor set is movably mounted in an inner cavity of the goods shelf bottom box. By arranging the fan blades and the air increasing bag, on the basis of an existing motor set, the fan blades and the air volume capable of being sucked by the fan blades, a certain ventilation quantity is increased for the inner cavity of the goods shelf bottom box, by arranging the blocking plate, kinetic energy of air flow is consumed through impact, the air flow speed is reduced, and the effective noise reduction effect is achieved; the heat conduction between the noise reduction clamping plate and the barrier plate is utilized to heat the air flow circulating in the air outlet, so that the temperature of the air circulating in the inner cavity of the goods shelf bottom box is further improved, the frosting degree of the surface of the evaporator is effectively reduced, and the frosting period is shortened.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a noise reduction air supply device for a refrigeration display cabinet. Background technique [0002] The refrigerated display cabinet is a cabinet commonly used in supermarkets, shopping malls, bars and other places to refrigerate alcohol and food at low temperature and display them. The existing refrigerated display cabinets are generally composed of fans, shelves, evaporators, outlets Air outlet, air inlet and other structures, by opening a cavity at the bottom of the shelf, an air inlet at one end of the cavity, a fan is installed near the air inlet, and an evaporator is installed on one side of the fan, and the fan is used to absorb external ambient air and cool down through the evaporator Cooling, converted into cold air, flows through the inside of the shelf from bottom to top, respectively flows to the air outlet at the bottom of each shelf bar, and disch...
