Wavelike finned type cold accumulation heat exchanger

Abstract

The invention discloses a wavelike finned type cold accumulation heat exchanger, which is mainly used for a cold accumulation container. The heat exchanger comprises an outer tube, wherein a front seal sheet of the outer tube and a rear seal sheet of the outer tube which are arranged on the end surface of the outer tube; the rear seal sheet of the outer tube bulges outwards to form a fill orifice; the fill orifice is provided with a rear seal cap; two inner tubes communicated through an elbow bend pipe are fixed in the inner cavity of the outer tube; the end surface of the inner tube is provided with a front seal sheet of the inner tube and a rear seal sheet of the inner tube; the front seal sheet of the inner tube and the front seal sheet of the outer tube are fixed together by welding the joints; the tail end of the joint is provided with a front seal cap; the upper side and lower side of the outer tube body are formed by wavelike tube walls; the wavelike tube wall forms a bulgy inner fin and a bulgy outer fin on the inner surface and the outer surface respectively; the inner tube body forms a bulgy outer fin on the outer surface. The wavelike finned type cold accumulation heat exchanger has simple structure, low manufacturing cost and high efficient heat exchange, contributes to high efficient heat exchange between a cold accumulation material in the outer tube and the outside, can avoid damage on the heat exchanger caused by the effect of expansion on heating and contraction on cooling, has cold accumulation material and has double functions of, cold charge and discharge.

Description

technical field [0001] The invention relates to a heat exchanger, in particular to a heat exchanger with finned corrugated tube walls. Background technique [0002] Heat exchangers are used in a wide range of applications, for example, in various refrigeration installations. The heat exchanger used in the traditional refrigeration device is connected with the components of the system by pipes to form a closed loop. The refrigerant inside the heat exchanger circulates, and the inner cavity channel generally does not need to be very large, such as air conditioning and refrigeration systems The inner diameter of the heat exchanger pipe is generally about 12-15mm. If the heat exchanger with only about 12-15mm internal diameter of this pipeline is used in large-scale equipment such as cold storage containers whose size reaches 20 feet (about 6 meters), its structure and size cannot meet the technical requirements. During the transportation of the cold storage container, the col...
