Abstract

The utility model relates to a multi-channel inner-toothed aluminum pipe for heat exchange. Channel partitions are arranged in the aluminum pipe; the interior of the aluminum pipe is divided into an internal channel (or a non-internal channel) and at least one external channel by the channel partitions; teeth are arranged on the channel partitions or the pipe walls of the external and internal channels; the interior of the aluminum pipe is divided into a plurality of channels by the channel partitions; the internal channel is in the center; the external channels are arranged on the periphery; without a change of the external diameter of the aluminum pipe, a size of channels passed through by fluid is narrowed, so each channel is ensured to be fully filled with fluid; a heat radiation area is further increased with the teeth on the channel walls; and with co-action of the channel partitions and the teeth, heat radiating efficiency is greatly improved.

Description

Heat exchange multichannel internal tooth aluminium tube

Technical field

The utility model relates to a kind of heat exchanger component, and there is the heat exchange multichannel internal tooth aluminium tube of many passages especially a kind of inside.

Background technology

Heat-exchange tube, is to be mainly used in the part heat of hot fluid to pass in the equipment of cold fluid, and fluid flows through and carries out heat exchange in heat-exchange tube inside.Heat exchanger is the common apparatus of chemical industry, oil, power, food and other many industrial departments, occupies aborning critical role.Parts important in heat exchanger are exactly heat-exchange tube, and the heat transfer effect of heat-exchange tube is also the important guarantee of heat exchanger performance.In Chemical Manufacture, heat exchanger can be used as heater, cooler, condenser, evaporimeter and reboiler etc., applies more extensive.Heat exchanger kind is a lot, but substantially can divide three major types according to the principle of cold and hot fluid exchange heat and mode: dividing wall type, hybrid and heat accumulating type.

Heat exchanger is for improving performance, can use a kind of fin type heat exchanging tube with more area of dissipation, common heat-exchange tube is all the direct spiral winding heat sink of appearance at aluminum pipe, and heat sink contacts with aluminum pipe appearance, by the area of heat sink, extends the radiating effect that expands heat-exchange tube.

Existing aluminum pipe is all generally to have tooth or anodontia single channel structure, or anodontia multi-channel structure; Single channel structural fluid can not be full of whole passage completely, and aluminum pipe only has part in heat exchange duty, affects the heat transfer effect of aluminum pipe, and anodontia fluid and aluminum pipe wall contact area are less, and area of dissipation is little, has reduced equally the heat transfer effect of aluminum pipe.Heat exchange porous internal tooth aluminium tube combines multichannel aluminum pipe and has the advantage of tooth aluminum pipe.

Summary of the invention

It is single channel structure or anodontia multi-channel structure that the utility model has solved existing heat exchanger aluminum pipe, underuse the defect of aluminum pipe heat transfer effect, a kind of heat exchange multichannel internal tooth aluminium tube is provided, by the inside of aluminum pipe by passage every being separated into multiple passages, simultaneously pipe wall and passage every on tooth, do not change under aluminum pipe external diameter, not only dwindle the channel size in aluminum pipe, increase area of dissipation simultaneously.

The utility model solves the technical scheme that its technical problem adopts: a kind of Multi-channel hot exchange aluminum pipe, aluminum pipe inside be provided with passage every, passage is every aluminum pipe interior separation being become to internal channel (or without internal channel) and at least one outer tunnel, and passage every or the tube wall of inside and outside passage have tooth.By passage every aluminum pipe interior separation is become to multiple passages, in central authorities be internal channel, in periphery be outer tunnel, do not changing the size that can dwindle the passage that fluid passes through under aluminum pipe external diameter, thereby guaranteeing that each passage is in full fluid state; On conduit wall, add tooth, further improve increasing heat radiation area, both actings in conjunction, have improved radiating efficiency greatly simultaneously.

The specific embodiment

Below by specific embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.

Embodiment 1: a kind of heat exchange multichannel internal tooth aluminium tube (referring to accompanying drawing 1), aluminum pipe inside be provided with passage every, passage is every becoming aluminum pipe interior separation internal channel and multiple outer tunnel, and passage is every comprising internal channel wall and the muscle between internal channel and aluminum pipe wall; There is tooth aluminum pipe wall inner side, and passage is every anodontia.

Above-described embodiment is several preferred version of the present utility model, not the utility model is done to any pro forma restriction, also has other variant and remodeling under the prerequisite that does not exceed the technical scheme that claim records.

Claims

1. a heat exchange multichannel internal tooth aluminium tube, it is characterized in that aluminum pipe inside be not only provided with passage every, passage is every aluminum pipe interior separation is become to internal channel, with multiple outer tunnels, have an internal channel and multiple outer tunnel at least, and have tooth on outer tunnel pipe wall, and passage is every anodontia, outer tunnel is multiple, and the passage being comprised of the muscle of radial arrangement between multiple outer tunnels is every separation, and the interval angle between muscle and muscle equates.

2. heat exchange multichannel internal tooth aluminium tube according to claim 1, it is characterized in that passage every thickness equate with the wall thickness of aluminum pipe.
