Abstract

The utility model relates to a heat exchanger. The utility model is characterized in that a pipe belt-typed fin-shaped heat exchanger is designed into a box-typed sawtooth-shaped heat exchanger; the indirect heat transfer mode that heat is transferred to the fin through the pipe is changed into the mode that the heat is directly transferred by a box-typed sawtooth-shaped fin. The structure of the utility model is that the utility model is composed of a device body and the box-typed sawtooth-shaped fin; the quantity of the box-typed sawtooth-shaped fin is at least one. As the utility model does not need a copper pipe, the cost can be reduced, and the size can be decreased; as the box-typed sawtooth-shaped fin is used, the heat transfer area is enlarged, and the heat-transfer efficiency is improved.

Description

Direct-heat type compound sawtooth heat exchanger

The utility model relates to a kind of heat exchanger.

Heat exchanger of all kinds is arranged in the prior art,, be nest plate type and pipe rock radiator as radiator of car engine; Air conditioning for automobiles and central air-conditioning adopt serpentine condenser and nest plate type fan coil; The civil buildings heating system adopts steel string sheet enclosed radiator or the like.They all are to carry out indirect heat transfer for fin or pipe racks by pipe heat-transfer, though simple in structure, wasteful dimension pipe, volume is big, the cost height, heat transfer efficiency is low.

The purpose of this utility model be to provide a kind of without copper pipe the heat exchanger of direct heat transfer, make it reduced volume, reduce cost, improve heat transfer efficiency.

The technical solution of the utility model is: with corrugated tube type fin shape heat exchanger designs is boxlike zigzag heat exchanger, becomes by pipe heat-transfer to give the direct heat transfer mode of the indirect heat transfer mode of fin into the boxlike zigzag sheet.Described boxlike zigzag heat exchanger is combined by body, boxlike zigzag heat transfer sheet, and its boxlike zigzag heat transfer sheet is at least a slice.

The utility model is owing to adopt boxlike zigzag heat transfer sheet, and the change indirect heat transfer is direct heat transfer, makes it to have enlarged heat transfer area, thereby has improved heat transfer efficiency; Owing to, thereby reduced cost without copper tube and fin.

Fig. 1 is a boxlike zigzag heat transfer sheet schematic diagram;

Fig. 2 is the heat exchanger schematic diagram with single boxlike zigzag heat transfer sheet;

Fig. 3 is the heat exchanger schematic diagram with a plurality of boxlike zigzag heat transfer sheets;

Fig. 4 is the utility model structural representation.

Below in conjunction with description of drawings embodiment of the present utility model.

Embodiment 1: as shown in Figure 2, the utility model is combined by body 1 and single boxlike zigzag heat transfer sheet 2, and its body is two hexahedron volumes, is positioned at the two ends of boxlike zigzag heat transfer sheet.

Embodiment 2: as shown in Figure 3, the utility model is combined by body 1 and a plurality of boxlike zigzag heat transfer sheet 2, and its body is two hexahedron volumes, is positioned at the two ends of boxlike zigzag heat transfer sheet, between the boxlike zigzag heat transfer sheet spaced apart from each other 3.

Embodiment 3: as shown in Figure 4, the utility model is combined by body 1 and a plurality of boxlike zigzag heat transfer sheet 2, its body is the hexahedron volume, and its boxlike zigzag heat transfer sheet is positioned at the body centre, and the two ends of boxlike zigzag heat transfer sheet are fixed on the wallboard 4 of body.

For increasing the firmness of boxlike zigzag heat transfer sheet, descend the two sides that the resistance to compression baffle 5 of combination is with it arranged thereon, the resistance to compression baffle is welded on the baffle plate 6 of body.

Heat liquid (or gas) enter body from inlet union, carry out heat exchange by boxlike zigzag heat transfer sheet after, flow away from outlet connection.
