The utility model discloses well metal sheet is for violently indulging the corrugate, has increased the turbulent flow nature of the heat transfer unit group air current of flowing through, improved the heat transfer capacity of air current self, has improved the ability that the thermal stress was born by heat transfer unit group, has increased the compressive capacity of heat exchanger.
Description
Technical field
This utility model gas-gas heat exchanger technical field, is specifically related to a kind of heat transfer unit group, movement and has the heat exchanger of this movement.
Background technology
Heat transfer technology is widely used in field of industrial production, environmental protection and field of energy-saving technology.Along with industrialized development, the deterioration of environment and the deficiency of energy, all heat exchanging technology propose higher, the requirement of renewal.Existing gas-gas heat exchanger, the most all uses tubular type, flat or discontinuous concave-convex heat transfer unit group.They have heat exchange efficiency low, and volume is big, and weight is big, non-refractory, the shortcomings such as intensity is low, and the life-span is short.
Summary of the invention
It is an object of the invention to overcome the most methodical deficiency, it is provided that a kind of heat transfer unit group, movement and there is the heat exchanger of this movement.
The technical solution of the utility model is: a kind of heat transfer unit group, including two pieces of corrugated sheet metal in length and breadth, and the transverse and longitudinal ripple of two pieces of metallic plates overlaps, equidistant wavy passage is formed between described two pieces of metallic plates, described two pieces of metallic plate two ends weldings, the ripple in length and breadth of described two pieces of metallic plates has protuberance and recess, is wherein provided with several flat positions at the protuberance of one piece of metallic plate, and described flat position and corresponding protrusions contact on another metallic plate are also fixed.
Preferably, the size of the ripple in length and breadth of described metallic plate is configured as required.
Preferably, described flat position is configured with stressing conditions as required.
A kind of movement, including at least two group heat transfer unit groups, welds between described heat transfer unit group two-by-two.
Preferably, the spacing between described heat transfer unit group is configured as required.
A kind of heat exchanger, including described movement.
The beneficial effects of the utility model: (1) becomes continuous print the most corrugated pressing metal plates, add the turbulent flow flowing through heat transfer unit group air-flow, improve the heat-transfer capability of air-flow self, thus improve the heat exchange efficiency that heat exchanger is overall.Heat exchanger is made to become volume little, lightweight.
(2) the most corrugated owing to have employed, the metallic plate of heat transfer unit group self is provided with after being heated and extends, the ability of cooling after-contraction, thus improves heat transfer unit group and bear the ability of thermal stress.And high temperature can be born.
(3) the most corrugated owing to have employed, and fixing point it is provided with in centre, thus add the anti-pressure ability of the heat exchanger being made up of heat transfer unit group, add the intensity of self.
(4) owing to adding Turbulence Flow, the dust in air-flow is made to be not easy to be attached on the metallic plate of heat transfer unit group.Make heat exchanger be difficult to dust stratification on the whole, extend service life.

Detailed description of the invention
The embodiment provided the present invention in conjunction with accompanying drawing is described in further detail:
As Figure 1-3, a kind of heat transfer unit group, including two pieces of corrugated sheet metal in length and breadth, and the transverse and longitudinal ripple of two pieces of metallic plates overlaps, forming equidistant wavy passage, described two pieces of metallic plate two ends weldings between described two pieces of metallic plates, the ripple in length and breadth of described two pieces of metallic plates has protuberance and recess, wherein being provided with several flat positions at the protuberance of one piece of metallic plate, described flat position and corresponding protrusions contact on another metallic plate are also fixed.
Wherein, the size of the ripple in length and breadth of described metallic plate is configured as required；Described flat position is configured with stressing conditions as required.
This utility model includes the first metallic plate 2 and the second metallic plate 22, described two pieces of metallic plate two ends weldings, described two pieces of metallic plates are pressed into transverse and longitudinal bellows-shaped, and transverse and longitudinal ripple overlaps, equidistant wavy passage A is formed between two pieces of metallic plates, the ripple in length and breadth of described two pieces of metallic plates has protuberance 1 and recess 11, suitable protruding point is selected to carry out flattening formation flat position at the protuberance of the first metallic plate 2, fix with protuberance corresponding on the second metallic plate and be connected, in the present embodiment, flat position 3 is fixing with at the corresponding B on the second metallic plate is connected, the present embodiment has flat position 3 everywhere, in figure, a represents convex ripple, b represents concavity ripple.
As shown in Figure 4, structural representation for a kind of embodiment of movement, movement includes two groups of heat transfer unit groups, and often two metallic plate two ends of group weld, automatically at C in figure, weld between two groups of heat transfer unit groups, being preferably in argon arc welding such as figure at D, the spacing between two groups of heat transfer unit groups is adjustable, H, V is two kinds of different gases respectively, and square crossing flows through heat transfer unit group.Do not leak mutually, carry out heat exchange by metallic plate.
A kind of heat exchanger, including described movement.
In this description, the present invention is described with reference to its specific embodiment.But it is clear that still various modifications may be made and conversion is without departing from the spirit and scope of the present invention.Therefore, specification and drawings is regarded in an illustrative, rather than a restrictive.
