Abstract
The utility model discloses a kind of plate heat exchangers, are welded by the metal sheet that the process such as punching press are fabricated by solder joint by two pieces, and for metal sheet after inflation deformation, uniformly distributed concave-convex honeycomb is presented in upper and lower surface.Nipple joint is installed on the diagonal line of metal sheet, one ball valve is installed to control the opening and closing of cold water circulating system pipeline at nipple joint, add the heat-preservation cotton of one layer of 20.0mm thickness on the outside of metal sheet and does isothermal holding in outermost, the utility model not only has the advantages that conventional plate heat exchanger using honeycomb concaveconvex structure, have efficient heat transfer, unit heat transfer area big again, while saving space, metal sheet internal flow high turbulence, fluid resistance decreasing loss loses lesser feature.
Description
Technical field
The utility model relates to technical field of heat exchangers, specially a kind of plate heat exchanger.
Background technique
In the industrial productions such as petrochemical industry and daily life, heat exchanger is as the essential equipment of heat exchange, property
It reliability for maintenance system, economy and the utilization efficiency of the energy can be improved plays very important effect.It is domestic board-like
Heat exchanger with herringbone it is corrugated based on, compact-sized, heat transfer efficiency is high but shape is single and resistance is big, operating temperature is limited, holds
Pressure energy power is low.Such as application No. is the plate heat exchangers of the patent application publication of CN201621402729.2 there is above-mentioned ask
Topic.
Summary of the invention
The utility model provides a kind of plate heat exchanger primarily directed to the above problem, solves usual heat exchanger work pressure
The disadvantage that power is low, operating temperature is limited.
The purpose of this utility model is mainly to be achieved by following proposal: a kind of plate heat exchanger is passed through by two pieces
It crosses the metal sheet that the process such as punching press are fabricated to be welded by solder joint, metal sheet is after inflation deformation, thereon
Uniformly distributed concave-convex honeycomb is presented in lower surface.
Metal sheet length L=750 ~ 800mm, width W=150 ~ 200mm, two pieces of metal sheet spacing B=6 ~ 7.5mm, weldering
Bore dia d=10 ~ 11mm, honeycomb diameter D=18 ~ 20.0mm, honeycomb spacing P=50 ~ 60mm, metal sheet surface area A=0.1 ~
0.16 m2。
Preferably, to enable hot-fluid fluent motion in metal sheet, spiral shell is installed on the diagonal line of metal sheet
Line adapter tube；
Preferably, nipple joint specification is 20.0mm × 2 Φ, and one ball valve of installation follows at nipple joint to control cold water
The opening and closing of loop system pipeline；
Preferably, add the heat-preservation cotton of one layer of 20.0mm thickness and most to reduce thermal loss on the outside of metal sheet
Do isothermal holding in outside；
The utility model proposes a kind of novel plate heat exchangers, not only have routine is board-like to change using honeycomb concaveconvex structure
The advantages of hot device, and have efficient heat transfer, unit heat transfer area big, saves space, metal sheet internal flow high turbulence
Meanwhile fluid resistance decreasing loss loses lesser feature.

Embodiment: as shown in Figure 1, a kind of plate heat exchanger, the gold being fabricated by two pieces by process such as punching presses
Belong to plate to be welded by solder joint, for metal sheet after inflation deformation, uniformly distributed concave-convex honeycomb is presented in upper and lower surface.
Metal sheet length L=780mm, width W=160mm, two pieces of metal sheet spacing B=6.5mm, welding hole diameter d=
10.5mm, honeycomb diameter D=19mm, honeycomb spacing P=55mm.
To enable hot-fluid fluent motion in metal sheet, nipple joint is installed on the diagonal line of metal sheet；
Nipple joint specification is 20.0mm × 2 Φ, installs a ball valve at nipple joint to control cold water circulating system pipeline
Opening and closing；
Add the heat-preservation cotton of one layer of 20.0mm thickness on the outside of metal sheet for reduction thermal loss and is kept the temperature in outermost
Processing；
The present embodiment proposes a kind of novel plate heat exchanger, not only has conventional plate-type heat-exchange using honeycomb concaveconvex structure
The advantages of device, and have efficient heat transfer, unit heat transfer area big, save space, metal sheet internal flow high turbulence it is same
When, fluid resistance decreasing loss loses lesser feature.
The above is only the preferred embodiment of the utility model, not makees in any form to the utility model
Limitation, although the utility model has been disclosed with preferred embodiment as above, is not intended to limit the utility model, any to be familiar with
