Embodiment 1

As shown in Figs. 1-2, the soldering plate of a kind of plate heat exchanger, including main panel 1, the quadrangle of main panel 1 are successively set There are first through hole 2, the second through-hole 3, third through-hole 4 and fourth hole 5, first through hole 2 and the second through-hole 3 are located at the same side, the Three through-holes 4 and fourth hole 5 are located at the opposite other side, the central axes of first through hole 2 and the second through-hole 3 about main panel 1 Symmetrically, third through-hole 4 and fourth hole 5 are symmetrical about a central axes of main panel 1, and the middle part of main panel 1 is successively arranged several Ripple 12, ripple 12 include first slope 8 and the second slope 9, and 8 upper end of first slope and 9 upper end of the second slope are fixedly welded with Convex top 6,8 lower end of first slope and 9 lower end of the second slope are fixedly welded with concave bottom 7, and the outside of main panel 1 is fixedly installed with sealing There is baffle 10 in area 11, the outside of seal area 11.

The radius of the radius of first through hole 2 and the second through-hole 3 is all larger than the radius of third through-hole 4 and fourth hole 5, so that The rate that delivered rate and be greater than hot side medium of cold side medium, can be effectively reduced heat in heat exchanger after soldering plate combination The temperature of side medium improves heat transfer effect, and main panel 1 is made of stainless steel material, ensure that device can permanent durable, ripple 12 Be in the shape of the letter V arrangement on main panel 1, increases the contact area of cold and hot side medium, so that cold and hot side medium has on main panel 1 Bigger heat exchanger time further improves exchange rate, and the angle of ripple 12 is obtuse angle, so that the ripple 12 of V-shaped Distribution will not influence the propagation rate of cold and hot side medium, can exchange heat quickly.

When the utility model is used, this brazing sheet is used cooperatively with other brazing sheets, when brazing sheet combines in heat exchanger After the completion, cold side medium is passed through by larger second through-hole 3 by siphunculus, hot side medium is passed through by smaller third through-hole 5, and cold side is situated between Matter will flow from bottom to top, and by two rows of cold medium cavitys that V-shaped arranges, hot side medium will flow from top to bottom, by V word One heat extraction dielectric cavity of shape arrangement, closely coupled between plate due to being brazed two-by-two, cold and hot side medium will not be mixed, instead And heat exchange is carried out by first slope 8 and the second slope 9, it is constantly passed through cold and hot side medium, is just able to achieve the drop of hot side medium Warm process, the cold and hot side medium after exchanging heat after the completion of exchange is respectively by 4 outflow heat exchanger of first through hole 2 and fourth hole, sealing Area 11 and baffle 10 effectively obstruct external environment, and heat exchange is normally carried out in guarantee heat exchanger.
