The heat exchanger structure vertical view of Fig. 2 embodiment of the present invention one.
Specific implementation mode
Embodiments of the present invention are described in detail below in conjunction with attached drawing.
This specific embodiment is only explanation of the invention, is not the limitation to invention, those skilled in the art
The modification that not creative contribution can be made to the present embodiment as needed after reading this specification, but as long as in this hair
The protection of Patent Law is all received in bright right.
Embodiment one
Such as Fig. 1-2, three chambers of one kind resting the head on formula heat exchanger, including the second plate body 1, the first plate body 2, the third plate being stacked together
Body 3.Second plate body 1 and third plate body 3 are located at the upper and lower surface of the first plate body 2.Second plate body 1 and the first plate body
2 surrounding welds together so that forms the second working medium passage between the first plate body 2 and the second plate body 1.3 He of third plate body
The surrounding of first plate body 2 welds together so that third working medium passage is formed between the first plate body 2 and third plate body 3.First plate
Body 2 is the hollow plate for being internally provided with the first working medium passage, is equipped with the first isolation part 21 in the first working medium passage, the first isolation part makes
It obtains the first working medium passage and is separated into multiple the first interconnected cavitys 61.The height of first cavity 61, along close to both sides
The direction of first isolation part 21 is gradually reduced.
The second plate body 1 is welded together with the first plate body 2 at the position corresponding to the first isolation part 21 using laser,
Form the second isolation part 11.Second isolation part 11 is so that the second working medium passage is separated into multiple the second interconnected cavitys
41.The height of second cavity 41, the direction along the second isolation part close to both sides are gradually reduced.
Third plate body 3 is welded together with the first plate body 2 at the position corresponding to the first isolation part 21 using laser,
Form third isolation part 31.Third isolation part 31 is so that third working medium passage is separated into multiple interconnected third cavitys
51.The height of third cavity 51, the direction along the third isolation part close to both sides are gradually reduced.
Second cavity 41 and third cavity 51 are symmetrical to be arranged in the both sides of the first cavity 2.In the present embodiment, by
One working medium passage is passed through refrigerant wherein as condensation working medium passage；Using the second working medium passage and third working medium passage as
Gas working medium channel is passed through air-flow to be condensed wherein（For example, coal mine gas gas）.Second working medium passage and third working medium are logical
Action principle in road is identical.Therefore, it is only described by taking the second working medium passage as an example herein.The coal mine watt of low concentration high humility
This gas is flowed into the second working medium passage in the second cavity 41, and refrigerant is flowed into the first cavity into the first working medium passage
In 61.Coal mine gas gas in second cavity is separated with the refrigerant in the first cavity by the outer wall of the first plate body, they are logical
The outer wall for crossing the first plate body carries out heat exchange.When refrigerant and the first plate body surface contact hot friendship is carried out with coal mine gas gas
It changes, takes away the heat in coal mine gas gas.Height of first cavity at the first isolation part position is smaller, advantageously allows this
Refrigerant molecules at position increase flow velocity and collision, to fully be exchanged heat.Since the first cavity is far from the first isolation
Height at the position in portion is larger, forms spiral status refrigerant stream at this location, improves heat exchange efficiency.Coal mine gas gas
The adherent flowing in the second cavity starts wall surface against the steam molecule of the second cavity inner wall and condenses into liquid film so that causes this
Vapor partial pressure declines at position.The incoagulable gas such as the methane in coal mine gas gas, which are gradually accumulated in be formed outside liquid film, not to coagulate
Property air film.Height of second cavity at 31 position of the second isolation part is smaller, advantageously allows the coal mine mash gas at the position
Molecule in body increases flow velocity and collision, to fully be exchanged heat so that the steam molecule in coal mine gas gas is being close to
Cavity inner wall forms eddy flow and is condensed at adherent place and formed a film.Since the second cavity is at the position far from the second isolation part 31
It is highly larger, the incoagulable gas partial pressure at the position is alleviated, the thickness for accumulating in the incoagulable gas outside liquid film is reduced
Degree so that steam molecule is more easy to be condensed across incoagulability air film arrival liquid film surface, to improve condensation efficiency.
In the present embodiment, condensed fluid outlet is equipped in the bottom of the second working medium passage and third working medium passage so that
The Water vapor condensation of coal mine gas gas in second working medium passage and third working medium passage is that water later being capable of condensed liquid
Outlet discharge.
Preferably, the first plate body in the present embodiment, the second plate body and third plate body can may be for stainless steel plate
Carbon steel sheet.And welded together by the way of underwater laser welding, underwater laser welds so that being welded in oxygen-free environment
It carries out, does not have bubble at welding position, substantially increase the intensity of heat exchanger, extend service life.At welding position
The width of weld seam 7 is preferably 0.5mm-10mm, such as 2mm.Bonding strength at the wider welding position of weld width is bigger, heat exchange
The bearing capacity of device is also stronger, and the service life also can be stronger.
Although the embodiments of the invention are described in conjunction with the attached drawings, but those of ordinary skill in the art can be in appended power
Profit makes various deformations or amendments in the range of requiring.
