Description

Technical Field

[0001] This utility model relates to the field of heat exchangers, and in particular to a plate heat transfer element with a micro-turbulence structure and a wide-channel plate heat exchanger. Background Technology

[0002] Plate heat exchangers are a new type of high-efficiency heat exchanger made up of a series of metal plates with a certain corrugated shape. They are composed of heat transfer plates, sealing gaskets, clamping plates and clamping bolts. The working fluid flows through the narrow and tortuous channel formed between two plates. The hot and cold fluids pass through their respective channels in turn, with a plate in between, through which heat exchange takes place.

[0003] Chinese Patent Publication No. CN216205604U discloses a plate heat transfer element with a micro-turbulence structure and a wide-channel plate heat exchanger. By protruding turbulence sections, the original wall boundary layer distribution is disrupted without damaging the flow pattern of the mainstream medium in the channel, and the laminar boundary layer is thinned, causing the flowing medium to generate wave-shaped biomimetic micro-turbulence, thereby improving heat transfer efficiency. However, since the plates do not have anti-overflow slots, heat may not be able to circulate during use, resulting in heat overflow. Therefore, we propose a plate heat transfer element with a micro-turbulence structure and a wide-channel plate heat exchanger. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a plate heat transfer element with a micro-turbulence structure and a wide flow channel plate heat exchanger. By setting flow channels inside the side of the plate, the flow channels are annular, which increases the flow volume of the plate and ensures that the hot and cold do not overflow during the flow process, thus making the heat preservation performance of the device better when the hot and cold flow is good.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A plate heat transfer element with a micro-turbulence structure and a wide-channel plate heat exchanger include a main body structure, a plate body structure installed in the middle of the main body structure, and a connecting mechanism installed at the front end of the plate body structure.

[0007] The plate structure includes a plate, a flow channel is fixedly provided inside the side of the plate, a flow groove is fixedly provided in the middle of the plate, and a through hole is fixedly provided inside the lower part of the flow groove. The flow channel is annular in structure, which increases the flow rate of the plate and ensures that hot and cold do not overflow during the flow process. The flow groove is also provided in the middle of the plate to further increase the heat exchange of the device.

[0008] Furthermore, the main body includes a front clamping plate, a hot-side inlet fixedly disposed on the right side of the front end of the front clamping plate, a hot-side outlet fixedly disposed on the lower right side of the front end of the front clamping plate, a cold-side inlet fixedly disposed on the upper left side of the front end of the front clamping plate, and a cold-side outlet fixedly disposed on the lower left side of the front end of the front clamping plate. Clamping bolts are movably installed inside the side of the front clamping plate, and a rear clamping plate is fixedly installed at the rear end of the front clamping plate by clamping bolts. By setting clamping bolts, the various components of the device can be disassembled, thereby facilitating the maintenance of the device.

[0009] Furthermore, the connecting mechanism includes a welding tube, inside which a metal conductive block is fixedly installed. By setting up the welding tube, the plates can be connected one by one, making the plate connection stable.

[0010] Furthermore, the plates are fixedly installed at the rear end of the front clamping plate. There are several plates, and the edges and corners of the plates are arc-shaped. By setting the outer ends of the plates to arc-shaped structures, the middle part of the device is less prone to dust accumulation, thus giving the device a certain degree of dust resistance.

[0011] Furthermore, the flow channel has an annular structure, the flow grooves are distributed in a matrix in the middle of the plate, and the through holes are distributed at equal intervals inside the flow grooves.

[0012] Furthermore, the hot-side inlet and hot-side outlet are connected, the cold-side inlet and cold-side outlet are connected, the clamping bolt and the front clamping plate are threadedly connected, and the clamping bolt and the rear clamping plate are threadedly connected.

[0013] Furthermore, the welded pipe has a tubular structure and is fixedly installed at both ends of the plate.

[0014] Furthermore, the front and rear ends of the metal conductive block are fixedly connected to the plate.

[0015] In summary, this utility model has the following beneficial effects:

[0016] 1. By setting flow channels inside the side of the plate, the flow channels are annular, which increases the flow rate of the plate and ensures that hot and cold do not overflow during the flow process, thus improving the heat insulation of the device during hot and cold flow. At the same time, a flow groove is set in the middle of the plate to further increase the heat exchange of the device. Multiple through holes are also set inside the flow groove to keep the upper and lower flow grooves connected, which facilitates heat conduction during heat exchange of the device.

[0017] 2. The tube structure of the welded tube makes welding more convenient, and the metal conductive block is set inside the welded tube so that heat can be quickly transferred between the front and rear plates after the plates are connected, thereby improving the heat transfer efficiency of the device. When the welded tube is connected to the plates by welding, the end of the metal conductive block is in contact with the plate, and the heat transfer effect is good when the two are in complete contact.

[0028] The connecting mechanism 3 includes a welding pipe 301, and a metal conductive block 302 is fixedly installed inside the welding pipe 301. By setting the welding pipe 301, the plates 201 can be connected one by one, so that the connection of the plates 201 is stable.

[0029] Plate 201 is fixedly installed at the rear end of front clamp 101. There are several plates 201. The corners of the plates 201 are arc-shaped. By setting the outer end of the plates 201 to an arc-shaped structure, the middle part of the device is not easy to accumulate dust, and the device has a certain degree of dust resistance.

[0030] The flow channel 202 has an annular structure, the flow grooves 203 are distributed in a matrix in the middle of the plate 201, and the through holes 204 are equally distributed in the interior below the flow grooves 203.
