Abstract

A method for production of plate polymer heat exchanger that includes laying polymer plates in pack to needed dimansions, those include channels for air passage, with connection of the plates in the pack at sides of the pack, at that connection of plates is performed by melting those at heating.

Description

The utility model belongs to the field of air conditioning and ventilation, in particular to plate polymer heat exchangers, and can be used to make heat exchangers for supply-exhaust units designed to provide heat exchange between supply and exhaust air.

A known method of manufacturing a heat exchanger (ERMO patent 1779965 E2809/00, B23R15/26,

В23Р21/00, dated 10/26/2005), which is accepted as the closest analogue. The method includes connecting the plates in the package along the corresponding sides of the package. Polymer plates are placed in a bag to the required size. The profiles of the plates are made in such a way that when they are placed in a package, channels are created for air flows. The sides of the package of plates to be joined are immersed in a container with an adhesive. Thanks to this connection of the plates in the package, it is ensured that the supply and exhaust air flows do not mix on the sides of the package.

The disadvantages of the closest analogue are the insufficient mechanical strength of the connection of the plates in the package on the sides of the package.

The task of the useful model is to create a method of manufacturing a plate polymer heat exchanger in which, by heating the plates in the package on the sides of the package, they are melted and connected to each other.

The task is solved in such a way that in the method of manufacturing a plate polymer heat exchanger, which involves stacking polymer plates to the required size in a package, which contain channels for the passage of air, and connecting the plates in the package along the sides of the package, according to a useful model with The joining of the plates is carried out by melting them during heating.

As a result of the proposed method, reliable mechanical strength of the connected plates in the package on the sides of the package of the plate polymer heat exchanger is ensured, which ensures tightness and, as a result, no mixing of supply and exhaust air flows.

The proposed method of manufacturing a plate polymer heat exchanger differs from its closest analogue by using the heating of the plates in the package on the sides of the package when they are connected, due to the fact that in contact with a string heated to the appropriate temperature, the plates quickly melt and bond, forming a mechanically strong and airtight joining the plates together.

An example of using a useful model.

The production of a plate polymer heat exchanger is explained by the drawings, where:

Fig. 1 - heat exchanger plates enclosed in a package;

Fig. 2 - the process of connecting the plates in the heat exchanger package;

Fig. C - heat exchanger assembly.

Polymer plates were cut to the appropriate size for the appropriate plate heat exchanger size. The plates are made of a polypropylene panel with a honeycomb structure using standard technology. The channels in the plate had a rectangular shape.

The formation of the package of plates for the heat exchanger was carried out as follows. Plates were stacked one on top of the other. Taking into account the location of the channels of the first plate, the second plate was laid turned at an angle of 90" relative to the first plate. The next plate was laid on the second plate turned 90" relative to the second plate, etc. In this way, a package of plates for the heat exchanger of the given dimensions was formed.

The plate pack was installed and locked in the standard setup. At the same time, three sides of the bag were fixed, and a nichrome string (5) was brought to the free side of the bag. The nichrome string, heated to the appropriate temperature, was set on the given size from the top of the bag from the edge of the free side of the bag and moved along the entire side of the bag with the help of a guide string (7). At the same time, the plates in the package were joined on the side of the package.

In the future, the other sides of the package were processed in the same way.

In contact with a string (5) heated to the appropriate temperature, the plates quickly melt and bond, forming a mechanically strong and hermetic connection between the plates.

The plate package was fixed at all corners with angle brackets (6). The package was hermetically closed from above and below with a lid (4).

The principle of operation of such a plate polymer heat exchanger (10) is as follows.

The supply air passes through the channels (1) of the heat exchanger (10) and enters the room, and the exhaust air passes through the channels (2), perpendicular to the channels (1) of the supply air.

The lamellar polymer heat exchanger (10) is intended for installation in the case of the supply and exhaust unit (not shown), which contains nozzles for the supply and removal of working media to the heat exchanger. Flows of working media, the first of which is, for example, supply air (8), and the second, exhaust air (9), under the influence of pressure forces created by superchargers (not shown), or in some other way, enter each system through corresponding nozzles channels During the movement of air flows through the channels (1, 2) of the heat exchanger (10), heat is transferred through the heat transfer surface of the plates from the hotter exhaust air to the cooler supply air, while the flows (8, 9) do not mix with each other.

After the heat exchange process is completed, the supply (8) and exhaust (9) air flows are removed from the case of the supply-exhaust unit through the corresponding nozzles
