A cartridge for purifying exhaust gases from the internal combustion engine of an automotive vehicle or some other source comprising a catalyst support matrix wound of metal foil and a metal jacket housing said support matrix wherein a press fit exists between the exterior of the support matrix and the interior surface of the jacket and the support matrix and the jacket are welded or brazed together within the area of the press fit. Processes and apparatus for producing the cartridge of the invention are also disclosed.

Disclosed is an evaporator comprising a connector member, a Venturi distributor connected to the connector member for receiving and distributing a coolant, wherein the Venturi distributor divides the coolant into a plurality of streams, a plurality of channels formed in the connector member for conducting the coolant streams from the Venturi distributor, the channels corresponding in number to the streams with each channel being positioned to receive one of the streams from the Venturi distributor, a plurality of evaporator pipes connected to the connector member in parallel flow arrangement, the pipes corresponding in number to the channels with each pipe being connected to one of the channels, thereby forming a continuous coolant flow path from the Venturi distributor via the channels to the evaporator pipes, and a collection chamber formed in the connector member for receiving the coolant from the pipes. Also disclosed is the use of the evaporator in air conditioners, particularly those of automotive vehicles.

Method for producing a cartridge for purifying exhaust gas

A passage is provided in a heat exchanger water compartment to permit extension of a tube therethrough and at the same time assist in sealing the tube and passage interface. The distance between the intersection of the lower bottom edge of the water compartment bottom part with the inner edge of the passage and the intersection of the horizontal extension of the upper edge of the bottom part in the direction of the passage extension has a positive value.

Cartridge for purifying exhaust gas

A passage is provided in a heat exchanger water compartment to permit expansion of a tube following its introduction into the bottom of the compartment. The heat exchanger is constructed so that a parameter K.sub.1 is in the range of 1.2 to 8. This parameter is equal to the length of the surface in contact between the tube and the passage multiplied by the ratio of the thickness of the bottom to the thickness of the tube wall, and the ratio of the tensile strength of the bottom material to the tensile strength of the tube material.

A support matrix for a catalytic reactor for scrubbing exhaust gases in internal combustion engines, made of high-temperature resistant steel made up of alternating steel panels, at least one of which is corrugated, and at least one of which is provided with projections or depressions interlocking with at least one adjacent steel panel.
