Through this embodiment, can utilize independent foaming to compress tightly the shell shape of frock to the water tank and stereotype, therefore, can just carry out the pouring of foaming material before covering the upper cover, then the upper cover plate need not to design the filling opening in order to fill foaming material, thereby make the upper cover plate can design the sclausura hole structure of integration, just also no longer need to beat sealed glue to the foaming material filling opening of upper cover plate, also no longer need upper cover plate wainscot lid and waterproof glue subsides, fundamentally avoids the foaming material to spill over from the upper cover plate filling opening, waterproof glue subsides on the upper cover plate and the sealed glue of upper cover plate filling opening department lead to the performance reduction owing to water tank or external temperature change, influence sealed effect, avoid the rainwater inside the gap infiltration water tank of upper cover plate filling opening, cause the corruption to the parallel flow microchannel, lead to revealing of refrigerant or even the scrapping of complete machine.
Example two
For the convenience of understanding, an example of a method for pouring a foaming material into a water tank is provided below, and on the basis of the first example, the present example will explain a specific method for pouring a foaming material into a sandwich layer formed by a shell and an inner container of a water tank.
Fig. 2 is a schematic flow chart of a second embodiment of a method for filling a foaming material in a water tank according to the embodiment of the present application.
Referring to fig. 2, an embodiment of a method for pouring a foaming material into a water tank in the embodiment of the present application includes:
in the foaming material filling process, the foaming material volume is enlarged and an acting force is generated on the inner wall of the water tank, when the stress on the inner wall of the water tank is unbalanced, the water tank can move to influence the filling of the foaming material, therefore, the water tank needs to be fixed before the foaming material is filled, and the water tank is prevented from moving to interfere the filling of the foaming material.
in order to prevent the foaming material from overflowing from the filling hole of the foaming pressing tool during filling, a foam layer is arranged between the top of the water tank liner and the foaming pressing tool, can play a role in interference fit, and is a first firewall for preventing the foaming material from overflowing from the filling hole of the foaming pressing tool.
Because the foaming material is poured into the interlayer between the outer shell and the inner container of the water tank, a pouring hole is required to be arranged on the foam layer, and the foaming material is poured into the interlayer through the pouring hole.
the filling holes in the foaming pressing tool are aligned with the filling holes in the foam layer to form through holes, so that the foaming material can directly reach the interlayer between the water tank shell and the inner container, and the filling is more efficient and accurate.
the lance tip guide tube needs to have a suitable length and an inner diameter and an outer diameter, so that the lance tip guide tube can be smoothly inserted into the through hole (the outer diameter of the guide tube is smaller than the minimum inner diameter of the through hole) and can enter into a sufficient depth (the length of the guide tube is long enough), thereby ensuring that foaming materials are poured into the interlayer to the maximum extent and reducing the probability of overflowing of the foaming materials from the through hole.
In addition, the foaming amount needing to be poured is adjusted before pouring, so that the cured foaming material can surround the inner container and cannot overflow from the through hole.
