Description

Description A COOLING DEVICE

[0001] The present invention relates to a cooling device wherein the evaporator empkce 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 empkced 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 empkced 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 empkced 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.

[0004] The aim of the present invention is the realization of a cooling device enabling the evaporators to be fixed into differently sized bodies with an evaporator retainer.

[0005] The cooling device realized in order to attain the aim of the present invention is explicated in the claims.

[0006] In the cooling device of the present invention, an evaporator retainer is utilized which is composed of more than one profile member, movable on or within one another, the length thereof adjustable by moving these profile members for fastening the evaporator to the body of the cooling devices in conformity with their different widths.

[0007] In an embodiment of the present invention, an evaporator retainer composed of profile members that can be inserted within each other, having a telescopic configuration is used.

[0008] In the embodiment of the present invention, the evaporator retainer is composed of two side profile members at its sides and a middle profile member that houses the side profile members. Furthermore, on the side profile members and/or the middle profile member, there are recesses and ribs providing the evaporator retainer to be partially locked when the desired length is attained and indicators showing to which length the evaporator retainer should be adjusted and pushing projections allowing the side profile members to be pushed precisely within small distances.
