Detailed Description

The present invention will be described in further detail with reference to the following examples and drawings, but the embodiments of the present invention are not limited thereto.

As shown in fig. 1 and 2, a welding microchannel heat exchange plate for condensation heat exchange comprises a rolling toothed plate 1 and a light plate 2, wherein a plurality of tooth grooves 3 parallel to each other are formed on the rolling toothed plate 1 through shaping roller processing, the length direction of the tooth grooves 3 is parallel to the length direction of the rolling toothed plate 1, and the light plate 2 is connected to one side of the rolling toothed plate 1 close to the tooth grooves 3 in a welding manner.

Combine fig. 3 and fig. 4 to show, after worn plate 2 and the welding of rolling pinion rack 1, tooth's socket 3 forms both ends and is the logical groove 4 that the opening set up between worn plate 2 and tooth's socket 3, and leads to groove 4 and is greater than logical groove 4 and is close to the width of rolling pinion rack 1 one side near smooth plate 2 one side width to make logical groove 4 be just reversing the trapezoidal form along the cross-section of rolling pinion rack 1 length direction. Because calorific capacity concentrates on the top of 3 lateral walls in tooth's socket during high frequency welding, resistance is big, through setting up logical groove 4 that is the shape of falling the trapezoid, 3 lateral walls in tooth's socket and the area of contact of worn plate 2 when reducing worn plate 2 and the welding of rolling pinion rack 1 avoid worn plate 2 and the tooth's socket 3 deformation of rolling pinion rack 1 when rolling pinion rack 1 pressfitting welding, ensure the rigidity of 3 lateral walls in tooth's socket.

Further, lead to two adjacent inside wall junctions of groove 4 and all pass through fillet transitional coupling. The round angle close to one side of the rolling toothed plate 1 is formed by rolling a forming roller with a side edge having a circular arc in the tooth shaping and rolling process. And the fillet that is close to light panel 2 one side melts and obtains in welding process, and the fillet can increase the contact or the overlap joint area between dental pad 1 and the light panel 2 here, increases the welding machine intensity of dental pad 1 and light panel 2, the compressive strength of the logical groove 4 lateral wall of packing. Through will leading to groove 4 adjacent two inside wall linking department settings through fillet transitional coupling, not only can reduce the possibility that rolls tooth mould (plastic roll) side sword tipping, and reduce fillet department because of the adsorption effect of liquid tension production.

Meanwhile, the two sides along the length direction of the toothed rolling plate 1 are both arc surfaces. The arc leveling at the side not only plays an attractive role, but also solves the problem of working medium leakage of cold solder joint and solder joint leakage in the middle of the microchannel (the leakage probability is extremely low, but the possibility is high, and the detection cannot be realized unless the microchannel is used).

It should be noted that fig. 1 and fig. 3 both show structural views of the heat exchange plate in different processing states according to the present embodiment. Referring to fig. 4, 5, and 6:

fig. 6 shows a cross-sectional view in the direction of the arrow a in fig. 3, when the optical plate 2 is separated from the dental plate 1 and is not welded;

fig. 5 shows a cross-sectional view in the direction of an arrow B in fig. 3, at this time, the optical plate 2 and the rolling toothed plate 1 are bonded and welded to form the through groove 4, but arc surface shaping is not performed on both sides of the rolling toothed plate 1;

fig. 4 shows a cross-sectional view in the direction of the arrow C in fig. 3, at this time, the two sides of the toothed rolling plate 1 are subjected to arc surface shaping, and a finished product is obtained.

The utility model discloses the heat transfer board simple structure of making uses in the condenser, and the effect performance is excellent, and manufacturing is simple, and production yield is high.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
