Abstract

The invention relates to a device for heating and refrigerating flowing liquid, and belongs to the field of temperature control systems. The device adopts a double-layer loop-shaped passage to heat or refrigerate the flowing liquid; the device is provided with a front heating plate, a rear heating plate and a middle heating plate which have the same shape and dimension; the middle heating plate is a rectangular plate; one side of the rectangular plate is processed with a front loop-shaped groove of the middle heating plate with a semicircular cross section; and the other side of the rectangular plate is processed with a rear loop-shaped groove of the middle heating plate with a semicircular cross section. The contact faces of the front heating plate and the rear heating plate towards the middle heating plate are processed with a loop-shaped groove of the front heating plate with a semicircular cross section and a loop-shaped groove of the rear heating plate with a semicircular cross section respectively; and metal hoses are positioned in the loop-shaped grooves to form the double-layer loop passage. The lateral surface of the heating plate is stuck with four semiconductor refrigerating sheets; and by heating of the heating plate, the temperature of the flowing liquid is indirectly controlled. The device has a simple structure, has no problem of liquid sealing, is convenient tomaintain and realizes even and rapid heating and refrigeration of the flowing liquid.
