Problems solved by technology

The mechanical stability of such packages is however poor, if the individual heat exchanger elements are only connected by conduits transporting the refrigerant
There is a risk that the pipe connecting the two heat exchanger elements will be kinked or due to poor dimensional stability of the wrapping structure, in the space provided for this purpose and shaped according to the desired structure of the heat exchanger There is a problem with the integrity of the heat exchanger
The structure of the heat exchanger elements can be reinforced by struts extending between the heat exchanger elements, but this involves significant effort and cost

Embodiment Construction

[0024] figure 1 Shown is a rear view of a domestic refrigeration device, such as a refrigerator or freezer. In the bottom of the refrigeration device there is provided a recess 1 towards the viewer, said recess opening towards the rear, through which a transverse support 2 fixed to the side wall of the housing extends. The compressor 3 and the condenser housing 4 are mounted on this transverse support. The side of the housing 4 facing the compressor 3 is open. On the side remote from the compressor 3 , the housing 4 is sealed off by the end wall 5 , but an opening is left on which the fan 6 is seated. The end wall 5 bears tightly against the rear wall 7 of the housing 4; the opposite edge of the end wall 5 is in contact with a vertical insulating wall between the recess 1 and the interior of the refrigeration unit (not shown in the figures).

Abstract

A heat exchanger comprises a number of plate heat exchange elements (11) connected in series. At least one stabilising element (15, 17) running transversely to the heat exchange elements (11) is provided with a number of notches (16). A heat exchange element (11) engages in each notch (16).

Description

technical field [0001] The invention relates to a heat exchanger, especially for use as a condenser or evaporator in domestic appliances. Background technique [0002] A conventional household appliance with a cold-wall construction generally comprises an evaporator in the form of a large-format plate placed on the rear wall of the refrigeration unit between the inner container and the layer of insulating material; and also a plate-shaped condensing A condenser, wherein the condenser is installed on the rear wall of the household appliance on the outside. With two heat exchangers (evaporator and condenser), heat exchange occurs between the refrigerant circulating inside the tubes and the air, either ambient air or air in the interior of the refrigeration unit. The low power density of heat exchangers means that large dimensions are required. [0003] Higher power densities can be achieved by means of forced-air heat exchangers, but such heat exchangers must have a compact ...
