Abstract
The utility model discloses a corrugated heat collection plate for the forced heat exchange of gas water heaters, wherein the heat collection plate is provided with holes for mounting water tubes. The corrugated heat collection plate is characterized by comprising corrugated plates, wherein each hole edge is provided with an extended arc tube edge, the connection of the hole edge and the valley of each corrugated plate is provided with distanced concaves. The holes are distantly and regularly arranged in a same direction. The convex top of the corrugated plates is lower than the hole edges. The corrugated heat collection plate has the advantages of high heat conduction efficiency, low cost and practicality.
Description
Technical field
The utility model relates to kitchen stove and accessory part field, specifically is a kind of ripple type heat collecting sheet that is used for the gas heater enhanced heat exchange.
Background technology
Gas heater is used for the heat exchanger of heat exchange and mainly is made up of water pipe and heat collecting sheet, and the water pipe of cold water through heat collecting sheet is housed is heated to temperature required.Present heat collecting sheet mostly is plate armature, and cigarette hot gas holdup time between heat collecting sheet is short, and hot service efficiency is not high, under the situation that nowadays energy prices constantly rise, influences the energy saving of gas heater.In order to improve the thermal efficiency, just like number of patent application is CN96224088.5, the applying date is 1996.11.22, name is called the patent application of water heater with heat exchanger core, constitute by heat collecting sheet group and dish intestinal tube, described heat collecting sheet group by at least three be set up in parallel, heat collecting sheet that shape is identical constitutes, each heat collecting sheet is provided with through hole, the dish intestinal tube has at least three straight lengths that are set up in parallel, described straight length passes the through hole on each heat collecting sheet, be connected in series by pipeline between each straight length, it is characterized in that described heat collecting sheet is case of bending on vertical.This patent strengthens the heat absorption area on heat collecting sheet, can improve thermal transition efficient, but because heat collecting sheet is a case of bending, the sealing requirements of through hole and pipeline is than higher, and if crooked irregular also may to cause flue gas to be detained uneven, it is not smooth to circulate, the heat exchange inequality, steam forms dew easily, so also requires heat collecting sheet and heat exchanger to have anti-corrosive properties preferably, so production cost is higher.
Summary of the invention
The purpose of this utility model is exactly in order to solve above-mentioned deficiency, and provides a kind of hot service efficiency height that has, the heat collecting sheet safe and practical, that production cost is low.
The technical solution that the utility model adopts in order to solve the problems of the technologies described above is as follows:
Originally the ripple type heat collecting sheet that is used for the gas heater enhanced heat exchange has the hole that water pipe is installed on this heat collecting sheet, it is characterized in that this heat collecting sheet is made of corrugated plating, and the curved pipe edge is extended along leaving in the hole.
This bore edges and corrugated plating trough junction are provided with recess at interval.
Described hole is that rule is arranged setting at interval.
Described hole is along being provided with in the same way.
Described corrugated plating protuberance wave crest height is lower than the hole along height.
The utlity model has following advantage:
One, adopt corrugated plating, can produce the turbulent flow of flue gas, strengthen the heat absorption area, and the corrugated plating of regular shape, make the flue gas circulation smooth and easy, heat exchange is even, improves heat exchange efficiency;
Two, the curved pipe edge is extended along leaving in the hole, and the through hole that helps on the corrugated plating is connected sealing with water pipe;
Three, this heat collecting sheet adopts that aluminium sheet etc. anti-ly gets rusty, resistant material, and simple in structure, cost is low, and result of use is good.

Fig. 2 is Fig. 1 broken section structural representation.
Description of reference numerals: corrugated plating 1, hole 2.
The specific embodiment
As shown in Figure 1 and Figure 2, the utility model is used for the ripple type heat collecting sheet of gas heater enhanced heat exchange, and it is made of corrugated plating 1, and corrugated plating 1 upper punch has the hole 2 of some installation water pipes, and the lower end, hole is for leaving the extension arc tips; Described punching 2 is that at interval rule is arranged and is provided with, and in corrugated plating settings of staggering, these 2 edges, hole and corrugated plating 1 trough junction are provided with the interval recess, are convenient to the installation of water pipe, help the sealing of the two connection; Porose edge is provided with in the same way; The wave crest height of described corrugated plating 1 protuberance is lower than the hole along height.
The shape in described hole can be for circular, square or other are irregularly shaped.
Described hole can be to corrugated plating inboard or arranged outside.
Claims (5)
