Abstract

The utility model discloses a brazing type heat exchanger with high heat exchange rate contains a plurality of sheets and is used for the board and the front and back end plate that stack of two kinds of different heat exchange gas/fluid A, B heat exchanges, wherein per 2 board circulation arrangements that cooperate and form two return circuits each other, the voltage-sharing is equipped with the ripple groove on the board, on the crest trough in ripple groove, sets up fin-shaped arch and strengthening rib in proper order the interval, between two relative boards, fin-shaped arch is relative setting on same medium runner, the strengthening rib sets up the top at the face of weld of two boards. The utility model discloses the structure is ingenious, and the heat transfer medium is on each runner, because fin-shaped bellied vortex effect, can slow down the velocity of flow of medium, increases the time of heat transfer, lets the heat transfer more thoroughly, and because the effect of vortex, can avoid forming the runner blind spot, promotes the blind spot and sweeps clearly, moreover, the holistic bearing capacity of heat exchanger can be improved greatly in the setting of strengthening rib, and application scope is wider, life extension.

Description

Brazed heat exchanger with high heat exchange rate

Technical Field

The utility model belongs to the heat exchanger field especially relates to a brazing type heat exchanger with high heat transfer rate.

Background

Brazed heat exchangers are excellent devices for heating, cooling, heat recovery, rapid sterilization, and other uses. However, the conventional brazed heat exchanger usually has a high flow rate and insufficient heat exchange for a relatively hot medium, and in order to achieve high heat exchange efficiency, the conventional brazed heat exchanger usually adopts a heat exchange wire extending mode, but the conventional brazed heat exchanger needs more equipment and occupies a large area, and the conventional brazed heat exchanger cannot be well adapted to the increasingly high pressure requirements of some special occasions, so that people need to find a better mode to solve the problems.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a brazing type heat exchanger with high heat transfer rate is provided.

The utility model discloses a realize through following technical scheme:

the brazed heat exchanger with high heat exchange rate comprises a plurality of stacked plate sheets and front and rear end plates for exchanging heat of two different heat exchange gases/fluids A, B, wherein every 2 plate sheets are mutually matched to form a plate (1-2) circulation arrangement of two loops, corrugated grooves are arranged on the plate sheets in a pressure equalizing manner, fin-shaped protrusions 3 and reinforcing ribs 4 are sequentially arranged on wave crests and wave troughs of the corrugated grooves at intervals, the fin-shaped protrusions 3 are oppositely arranged on the same medium flow channel between the two opposite plate sheets, and the reinforcing ribs 4 are arranged above welding surfaces of the two plate sheets.

Preferably, the reinforcing ribs 4 are arranged in a segmented structure uniformly distributed in the corrugated grooves.

The utility model has the advantages that:

the utility model discloses a brazing type heat exchanger with high heat transfer rate, the structure is ingenious, heat transfer medium is on each runner, because fin-shaped bellied vortex effect, can slow down the velocity of flow of medium, increase the time of heat transfer, let the heat transfer more thorough, heat exchange efficiency is better, and because the effect of vortex, can avoid forming the runner blind spot, promote the blind spot to sweep clearly, reduce and wash the number of times, moreover, the setting of strengthening rib can improve the holistic bearing capacity of heat exchanger greatly, in order to satisfy the special pressure requirement, application scope is wider, the life extension, be worth promoting.

Drawings

For ease of illustration, the invention is described in detail by the following specific examples and figures.

Fig. 1 is a schematic structural view of a plate heat exchanger according to the present invention;

FIG. 2 is an enlarged view of the structure of FIG. 1 at C;

fig. 3 is a partial structural view of the plate.

Detailed Description

As shown in fig. 1-3, the brazed heat exchanger with high heat exchange rate comprises a plurality of stacked plates and front and rear end plates for exchanging heat of two different heat exchange gases/fluids A, B, wherein every 2 plates are mutually matched to form a 1-2 circulation arrangement of two loops, corrugated grooves are uniformly distributed on the plates, fin-shaped protrusions 3 and reinforcing ribs 4 are sequentially arranged at intervals on wave crests and wave troughs of the corrugated grooves, the fin-shaped protrusions 3 are oppositely arranged on the same medium flow channel between the two opposite plates, and the reinforcing ribs 4 are arranged above the welding surfaces of the two plates.

And the sheets are vacuum brazed by taking copper as brazing filler metal.

The reinforcing ribs 4 are arranged in a sectional structure which is uniformly distributed in the corrugated groove.

The utility model discloses in, the fluid is on each runner, because fin-shaped bellied vortex effect, can slow down the velocity of flow of medium, increases the time of heat transfer, lets the heat transfer more thoroughly, and heat exchange efficiency is better, and because the effect of vortex, can avoid forming the runner blind spot, promotes the blind spot and sweeps away clearly, reduces and washs the number of times, and in addition, the setting of strengthening rib can improve the holistic bearing capacity of heat exchanger greatly to satisfy the special pressure requirement, application scope is wider, and life extension is worth promoting.

The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that are not thought of through the creative work should be covered within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
