Abstract
The invention relates to a board type exchanger that has low flow resistance at the flute of angle hole and second sealing. The feature is that the layer location of flute bottom layer bearing sealingspacer is different between different group angle hole sealing structure and corresponding angle hole second sealing structure. When the heat exchanging board stacking together, the interval channelheight between boards formed by angle holes sealing spacer flute and corresponding second sealing spacer flute exceeds the height of buckle ripple. Thus, the flow resistance would be decreased.
Description
Technical field
The present invention relates to a kind of plate type heat exchanger, relate in particular to a kind of plate type heat exchanger that seals with gasket seal.
Background technology
This plate type heat exchanger is to fit together with the some heat exchange plates that are roughly rectangle or square and other shapes, between heat exchange plate, seal with gasket seal, on heat exchange plate, has heat exchange structure, by heat exchange plate on heat exchange structure form with concavo-convex brace rod bubble clocklike, by heat exchange plate on heat exchange structure form with ripple;
There are hole, four angles hermetically-sealed construction and corresponding hole, four angles secondary seal structure in heat exchange structure two ends on every heat exchange plate, this four angles hole hermetically-sealed construction and hole, pairing four angles secondary seal structure by two groups to constituting, the two ends that two angles hole hermetically-sealed construction that each group is right and hole, pairing two angles secondary seal structure lay respectively at heat exchange structure.
In the hermetically-sealed construction of hole, four angles of on heat exchange plate this, can have zero to four holes, angle with actual perforate bore.
Its weak point of plate type heat exchanger with the prior art manufacturing is; Because on heat exchange plate in the hermetically-sealed construction of hole, four angles and in the secondary seal structure of hole, pairing four angles, the layer position of its support gasket seal bottom portion of groove all is identical, when each heat exchange plate is stacked piecewise, each hole, angle gasket seal groove and between the plate of pairing secondary seal pad groove the runner height only be a concavo-convex ripple height, because the evolute limited length of hole, angle gasket seal groove and secondary seal pad groove, so actual internal area between the plate that the width that actual internal area is significantly less than heat exchange structure on the heat exchange plate between the plate that this line length and ripple height constitute and a ripple height constitute is at each hole, angle gasket seal groove and only have at pairing secondary seal pad groove that actual internal area will the bigger fluid resistance of heat exchanging medium generation between the plate of a concavo-convex ripple height.
Summary of the invention
The purpose of this invention is to provide a kind of like this plate type heat exchanger; When each heat exchange plate is stacked piecewise, under the prerequisite that guarantees the gasket seal sealing effectiveness, the runner height should enlarge actual internal area herein and reduce the fluid resistance that heat transferring medium produces in this place of flowing through with this greater than the height of a concavo-convex ripple between the plate of being made up of each hole, angle gasket seal groove and pairing secondary seal pad groove.
