Abstract
The invention relates to a heat exchanger, in particular to a heat exchange plate set and a plate type heat exchanger. The heat exchange plate set is used for simplifying a water channel structure, reducing waterflow resistance, and improving heat exchange efficiency. The heat exchange plate set is composed of a first heat exchange plate piece and a second heat exchange plate piece through overlaying. The first heat exchange plate piece and the second heat exchange plate piece are respectively and correspondingly provided with rows of evenly-distributed concave-convex bodies. Concave-convex water channels are formed between the lower concave faces of the upper concave-convex bodies on the first heat exchange plate piece and the upper convex faces of upper concave-convex bodies of the second heat exchange plate piece. A waterflow circuit is formed between each set of water channels. The invention further provides a plate type heat exchanger which is formed by the heat exchange plate set through overlaying, and the plate type heat exchanger reduces resistance of the waterflow passing through the water channels, improves stability of heat exchange between water and gas, and thereby improving heat exchange efficiency. The plate type heat exchanger is applied to a gas water heater, is simple in structure, small in size, and low in cost. The concave-convex water channels and gas channels are directly formed between plate pieces after brazing. Flowing resistance is small, and heat exchange efficiency is high.
Description
Technical field
The present invention relates to a kind of heat exchanger, particularly a kind of plate package and plate type heat exchanger thereof.
Background technology
Plate type heat exchanger is the heat transmission equipment that a kind of heat transfer efficiency is high, compact conformation, heat exchange area per unit volume are large, safe and reliable.The plate type heat exchanger that current gas heater uses, in order to increase the heat exchange area of water and gas, two pieces of correspondences are provided with concavo-convex hole shape thing heat exchange plate laminating and soldering form airtight concavo-convex hole shape runner (i.e. water channel) and form plate package, again some plate package superpositions are formed plate type heat exchanger, and between adjacent plate package, form concavo-convex hole shape runner (i.e. air flue).During use, fire row is positioned at the side of air flue, the thermal current produced after passing into the fuel gas buring of fire row flows into from the air flue between adjacent heat exchanger plates group, current simultaneously to be heated water channel flowing in plate package, thus realizes the heat exchanging process between air flue and water channel.But the channel structure of this concavo-convex hole shape is complicated and water resistance is comparatively large, reduces the stability of water and gas heat exchange, thus have impact on heat exchange efficiency.
Summary of the invention
The invention provides the plate package that a kind of gas heater uses, simplify channel structure, reduce resistance to water-flow, improve heat exchange efficiency; Additionally provide a kind of plate type heat exchanger be made up of this plate package simultaneously, reduce the resistance of current when water channel, improve the stability of water and gas heat exchange, thus improve heat exchange efficiency.
