TR TR TR TR DESCRIPTION This invention relates to a cooler containing an evaporator. Coolers consist of two upper and lower compartments, namely the fresh food compartment or the freezer compartment. Generally, the freezer compartment is at the top and the refrigerator compartment is at the bottom. Cooling of the freezer compartment is carried out by the evaporator wrapped around the compartment. In the refrigerator compartment, the evaporator is placed inside the rear wall. In conventional refrigerators, cooling of the refrigerator compartment occurs by natural convection. The warm and humid air rising along the door cools on the back wall and releases moisture. Temperature-controlled compartments in coolers have been observed more frequently in recent years. In the application of such partitions, flap, direct or indirect cooling solutions come to the fore. Additionally, integrated electronic control applications with sensors are widely used. Temperature-controlled compartments create the need for extra capacity and/or efficient and distributed management of capacity. In this context, in addition to the elements mentioned above, it is also observed that integrated evaporator solutions integrated with air ducts provide effective results in providing the desired capacities. In the European Patent Application No. EP2370759, which is in the state of the art, an evaporator is described, which has a rectangular shaped plate, which is bent into a box form open at front and back and placed on the inner surface of the freezer compartment, and its parts and a pipe laid in the form of a serpentine. In the European Patent Application No. EP0547310, which is another document within the state of the art, a two-compartment cooler is described and an evaporator extending to the refrigerator compartment after being laid on the floor, ceiling and rear wall of the freezer compartment is described. Another application in the state of the art is included in the Chinese Utility Model Application No. CN212378320. According to this document, a single-row evaporator consisting of two parts with different fin spacings is arranged at the back of the cooling room and is used for cooling the cooling room. The purpose of this invention is to realize a cooler that provides effective and homogeneous cooling conditions and provides energy consumption gains by reducing compressor operating times. The cooler defined in the first claim and the claims attached to this claim, which is realized in order to achieve the purpose of this invention, consists of an air duct, a wall that divides the air duct into two in the direction of the air flow, and a pipe placed inside the air duct, having an inlet and an outlet, formed by bending it. It contains at least one evaporator, in which the refrigerant circulates, located on the same plane, with a wall between two side-by-side serpentine forms. In an embodiment of the invention, the adjacent sections of the evaporator on both sides extend in the same horizontal direction, with a wall between them. In one embodiment of the invention, the length of the pipes between the evaporator passes on both sides is equal. In this application, two serpentine forms side by side are symmetrical to each other, even though there is a wall between them. In one embodiment of the invention, the pipe connecting the serpentine form on both sides is straight and extends parallel to the lower edge of the wall. In another embodiment of the invention, the pipe is bent to be parallel to both side edges and the top edge of the wall and connects the serpentine form on both sides.

In another embodiment of the invention, the pipe is bent so that it is parallel to both side edges and bottom of the wall and connects the serpentine form on both sides. In this application, the pipe connecting the serpentine form on both sides partially surrounds the wall and does not only surround the upper edge of the wall. In both applications of the invention above, the adjacent passes on both sides separated by the wall are not located in the same horizontal direction and are positioned in a surprising way.

In this application, the pipe connecting the serpentine form on both sides partially surrounds the wall, not just the lower edge of the wall. In an embodiment of the invention, the evaporator pass gaps are equal to each other. In one embodiment of the invention, the evaporator is used to cool the refrigerator or freezer compartment. In one embodiment of the invention, the evaporator is used to cool the temperature-controlled compartment. In one embodiment of the invention, the evaporator is a finned tube type evaporator. In another embodiment of the invention, the evaporator is an open tube type evaporator. In another embodiment of the invention, the evaporator is a wire-tube type evaporator. With this invention, the cooler and/or freezer and/or temperature-controlled compartment where the evaporator is placed can be cooled effectively and effective capacity use is ensured for all cooling volumes.
