[0001] The present invention relates to a cooling device wherein the evaporator emplace
within its body framework is fixed by an evaporator retainer.
[0002] In cooling devices, for example in deep freezers, the evaporator is folded in the
shape of a serpentine to be emplaced within the body to carry out the cooling process.
Accordingly, the heat transfer between the evaporator pipes and the inner environment
of the cooling device is increased. In this type of cooling devices, wire-on-tube
or roll-bond type of evaporators are used. After the evaporator is emplaced within
the body, it is attached into the inner body of the cooling device by various methods
so that it is not displaced during usage. An evaporator retainer that is affixed to
the evaporator and the side walls of the cooling device is used in order to attach
the evaporator to the inner body of the cooling device. The evaporator retainer can
be of various lengths depending on the width of the refrigerator and the thickness
of the side walls of the body and each profile member having a different length has
to be produced separately. For example, since the width of the evaporators that extend
like shelves between the side walls of the cooling devices with different standard
widths like 54 cm, 60 cm, or 70 cm and hence the length of the evaporator retainers
that help in fastening the evaporators to the side walls have to be according to these
standard widths, then a different evaporator retainers in length have to be used for
each cooling device of different width which results in increasing the production
costs.
[0003] In the patent document no.
DE2638364, the evaporator that is emplaced inside the cooling device body is fixed inside the
body with a front strip attached to the front portion of the evaporator and two fixture
elements attached to the two sides of the profile member. The fixture elements are
seated in the housings on the side walls and fix the front strip and the evaporator,
one side of which is inserted into the channel in the front strip.
