Problems solved by technology

The main disadvantage of this technology is that its heat transfer mainly depends on the conduction of two parallel plates, and the conduction efficiency is low, especially when the phase between the two plates is not tight and there is a gap, it will have a greater impact on the heat conduction effect. Serious; secondly, the medium circulation channel is composed of a straight cylindrical cavity between parallel plates, so there is a problem of heat exchange efficiency as mentioned above, that is, energy utilization; in addition, this technology first consists of a support plate and a solid column The frame structure is formed, and then the heat exchanger shell is formed by closing the front, rear, upper and lower covers. It is still troublesome to maintain and disassemble.

Abstract

The invention discloses a wide-channel plate heat exchanger which comprises a support, a shell, a heat exchange core body, a heat exchange medium inlet, a heat exchange medium outlet, a heat transfer medium inlet and a heat transfer medium outlet, wherein the heat exchange medium inlet, the heat exchange medium outlet, the heat transfer medium inlet and the heat transfer medium outlet are positioned in the shell and communicate with the heat exchange core body; the heat exchange core body comprises heat exchange medium circulation channels and heat transfer medium circulation channels; the heat exchange medium circulation channels are provided with a plurality of nest-shaped turbulence chambers; and the shell is a combined structure. According to the wide-channel plate heat exchanger, the heat exchange efficiency is high, the energy consumption is low, and the maintenance is convenient.

Description

technical field [0001] The invention belongs to the technical field of heat exchange equipment, in particular to a wide channel plate heat exchanger. Background technique [0002] Plate heat exchangers are widely used in various fields because of their high heat transfer efficiency, low energy consumption, and reversible heat transfer direction. Most of the traditional plate heat exchangers are mostly composed of square shells and inner cavities arranged and fixedly welded to form a heat exchange structure in which the hot medium and cold medium channels alternate. Although this structure is simple in structure and easy to manufacture, when it is used for heat exchange with a medium containing solid particles or viscous slurry, the flow rate of the medium is too fast, the heat exchange efficiency is low, and the heat exchange effect is not ideal, and It often leads to waste of energy; if the flow rate of the medium is too slow, it is easy to cause a large amount of heat exc...
