Net formula heat exchanger plate is superimposed up and down and by argon arc welding or laser welding mode by plate by two pieces of plates for offering through hole
Piece surrounding is internally formed plate fluid passage together with through hole welding side seam in the net formula heat exchanger plate.
In one preferred embodiment of this utility model, also welding is provided with fluid in plate on the net formula heat exchanger plate
Adapter, fluid connecting pipe is correspondingly arranged with the plate fluid passage in the plate.
In one preferred embodiment of this utility model, fluid connecting pipe is welded with two and is located at respectively described in the plate
The diagonal angle of net formula heat exchanger plate.
In one preferred embodiment of this utility model, fluid connecting pipe protrusion is arranged at the heat exchanger shell in the plate
It is outside.
In one preferred embodiment of this utility model, in the plate end of fluid connecting pipe be respectively positioned on the feed tube and
Inside drain pipe.
In one preferred embodiment of this utility model, the plate fluid passage welding forming or elder generation after first punching press
Expansion-molded processing after welding is obtained.
It is described in the utility model for a kind of heat exchanger of net formula lung shape heat exchanger plates, this utility model had both reduced plate outer fluid
Flow resistance, while larger Reynolds number also can be obtained at a lower rate forms turbulent flow, is effectively improved heat exchange system
Number so that heat exchanger is simpler, efficient, energy-conservation, compact conformation, saves occupation of land space and initial investment, using this product
It is less than traditional plate type heat exchanger resistance, and the preferable coefficient of heat transfer can be reached.

Specific embodiment
Preferred embodiment of the present utility model is described in detail below, so that advantages and features energy of the present utility model
It is easier to be readily appreciated by one skilled in the art, apparent clearly defines so as to make to protection domain of the present utility model.
It is described in the utility model for a kind of heat exchanger of net formula lung shape heat exchanger plates, as shown in Figure 1, Figure 2 with reference to shown in Fig. 3, including
Net formula heat exchanger plate 1, heat exchanger shell 2, feed tube 3 and drain pipe 4, the net formula heat exchanger plate 1 is from top to bottom etc.
It is spaced apart to be arranged in the heat exchanger shell 2 and forms lung shape hollow structure, the feed tube 3 and drain pipe 4 is longitudinal respectively
It is arranged on heat exchanger shell 2, the net formula heat exchanger plate 1 is superimposed up and down and is passed through by two pieces of plates for offering through hole 5
Argon arc welding or laser welding mode form welded seam 6, by plate surrounding together with the welding side seam of through hole 5, and in institute
State net formula heat exchanger plate 1 and be internally formed plate fluid passage 7.
Also welding is provided with fluid connecting pipe 8 in plate on the net formula heat exchanger plate 1, fluid connecting pipe 8 and institute in the plate
State plate fluid passage 7 to be correspondingly arranged.
Fluid connecting pipe 8 is welded with two and respectively positioned at the diagonal angle of the net formula heat exchanger plate 1 in the plate.
The protrusion of fluid connecting pipe 8 is arranged at outside the heat exchanger shell 2 in the plate.
The end of fluid connecting pipe is respectively positioned on inside the feed tube 3 and drain pipe 4 in the plate.
