Detailed Description
The invention will be further described with reference to the accompanying drawings:
as shown in fig. 1-3, the thin plate heat exchanger of the present invention comprises two thin plates 2 connected together at their peripheral edges 1, wherein the edge 1 at one side is provided with a heat exchange medium inlet 6, the edge 1 at the side opposite to the edge 1 provided with the heat exchange medium inlet 6 is provided with a heat exchange medium outlet 4, and the heat exchange medium inlet 6 and the heat exchange medium outlet 4 are both communicated with a middle cavity enclosed by the two thin plates 2; a plurality of welding points 3 are arranged between the two thin plates 2.
In this embodiment:
the plurality of welding spots 3 are arranged in a honeycomb shape, and the welding spots 3 are arranged more densely and moderately, so that the heat exchange efficiency of the heat exchange device is further improved.
A plurality of baffling welding lines 5 are additionally arranged between the two thin plates 2. One end of each baffling welding line 5 is connected with one side edge 1 of the thin plate 2, a flow space 7 is arranged between the other end of each baffling welding line and the other side edge 1 of the thin plate 2, and the flow spaces 7 formed by two adjacent baffling welding lines 5 and the edges 1 of the thin plates 2 are respectively close to the edges 1 of the two opposite thin plates 2; the heat exchange medium inlet 6 and the heat exchange medium outlet 4 are respectively positioned at two sides of the baffling welding line 5. The flow path of the heat exchange medium in the middle cavity enclosed by the two plates is increased, and the heat exchange efficiency is further improved.
When the device is manufactured, the edges 1 of the two thin plates 2 are integrally connected through welding, then the other positions of the two thin plates 2 are welded through laser to form a plurality of welding points 3, and then the two thin plates 2 are subjected to water pressure expansion forming. When the heat exchange device is used, a heat exchange medium is input into the cavity between the two thin plates 2 through the heat exchange medium inlet 6, the arrangement of the welding spots 3 plays a role in disturbing flow for the heat exchange medium, the heat exchange efficiency is improved, and the heat exchange efficiency is further improved due to the fact that the thin plates 2 of the heat exchange device are thin in wall thickness; the heat transfer medium flows around the weld points 3 on the one hand and around the baffle weld lines 5 on the other hand, back and forth through the flow spaces 7 between each baffle weld line 5 and the edge 1 of the sheet 2, the heat transfer medium flow curve 8 being substantially as shown in fig. 1. The heat exchange device has a simple structure, is thinner, occupies small space in the sterilizer and is beneficial to improving the space utilization rate of the sterilizer inner chamber.
