[0030] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] In this embodiment, in order to stably install the two rows of heat exchange cores, the inventors set up a bracket structure to provide stable support for multiple heat exchange cores. Therefore, a core bracket is set inside the cooling unit, including a bracket module located at the bottom, and support bottom beams are set on both sides of the upper end of the bracket module.

[0032] Please refer to Figures 1 to 3 , Figure 1 A cross-sectional schematic diagram of a specific implementation of a heat exchange core supporting top beam provided by the utility model; Figure 2 This is a schematic diagram of the installation of a specific implementation of the heat exchange core supporting top beam provided by the utility model; Figure 3 This is a partially enlarged view of a specific implementation method of the heat exchange core supporting top beam provided by the utility model.

[0033] The specific implementation of the utility model provides a heat exchange core support top beam, which is applied to the core bracket in the cooling unit. The core bracket includes a bracket module 19. Support bottom beams are arranged on both sides of the upper end of the bracket module 19. Support oblique beams are arranged on the support bottom beams on both sides. The top ends of the support oblique beams on both sides are inclined inward and close to each other. The top ends of multiple support oblique beams are commonly connected to the support top beam to form a frame structure with a cross-section similar to a triangle. An evaporator module 16 is arranged on the inner side of the hypotenuse of the frame structure. The upper end of the support bottom beam is connected to the lower end of the evaporator module 16. The upper ends of the two evaporator modules 16 are close to each other and commonly connected to the support top beam. At the same time, the outer side of the hypotenuse of the frame structure is connected to one side of the heat exchange core 17. At the same time, two outwardly extended water absorber mounting frames 15 are installed on both sides above the support top beam. The water absorber mounting frames 15 are connected to the other side of the heat exchange core 17 below, and a condenser module 18 is installed above the two water absorber mounting frames 15. That is, with the heat exchange core supporting top beam as the center, the two evaporator modules 16 and the two water absorber mounting frames 15 are spread out in four different directions and arranged symmetrically to form an X-shaped structure, and two rows of heat exchange cores 17 corresponding to each other are embedded between the water absorber mounting frames 15 and the evaporator modules 16 on the same side.

[0034] The top beam supporting the heat exchange core is a hollow profile beam, which is a long strip profile formed by one-piece stretching and extrusion. The outer wall of the profile beam is formed by two heated plates 1 and a cooled part 2. The three parts surround the outer shell of the profile beam, and the three parts form the hollow part of the profile beam. At the same time, heating and cooling are defined according to the temperature environment of the nearby parts. The heated plate 1 is close to the condenser module 18, and the condenser module 18 condenses and releases heat during operation, so the part close to it is the heated part. The cooled part 2 is close to the evaporator module 16, and the evaporator module 16 evaporates and absorbs heat during operation, so the part close to it is the cooled part.

[0035] The tops of the two heated plates 1 are connected, and the bottoms of the two heated plates 1 are spread out to both sides, and the bottoms of the two heated plates 1 are respectively connected to the two ends of the cold part 2, and the three parts are surrounded by a profile beam with a cross-section similar to a triangle, wherein the heated plate 1 is used to connect the bottom of the water absorber mounting frame 15, and the cold part 2 is used to connect the evaporator module 16.

The reinforcing plates of various arrangements work together to divide the inside of the profile beam into multiple spaces, and the profile beam and the internal reinforcing rib plate assembly are stretched and extruded together.

[0036] The reinforcing rib plate assembly arranged inside the profile beam has higher equipment strength and provides a more reasonable force-bearing structure compared to traditional hollow sheet metal parts. According to the force analysis of the supporting top beam by each connecting component, the corresponding reinforcing structure is added inside the profile beam to achieve targeted reinforcement.

Preferably, in order to reasonably distribute the force of the heated plate 1, the end of the main horizontal reinforcing plate 3 and the end of the secondary horizontal reinforcing plate 4 divide the inner side of the heated plate 1 into three equal parts.
