Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-4, the present utility model provides a technical solution: the utility model provides a novel freezer top aluminium calandria, includes calandria 1, and horizontal casing 2 is the open shell structure in both ends, and horizontal casing 2's top is fixed in on the freezer roof. The connecting frames 21 are respectively fixed on the top surface of the horizontal shell 2 near four corners, and the horizontal plates at the tops of the connecting frames 21 are fixed on the top plate of the refrigeration house through expansion bolts. The two ports of the horizontal shell 2 are respectively provided with a supporting beam 23 for supporting the calandria 1, and the top surface of the supporting beam 23 is provided with a plurality of lower clamping grooves 231 which are correspondingly matched with the calandria 1 in a clamping way.

The middle part of the calandria 1 is arranged in the inner cavity of the horizontal shell 2, wherein the bottoms of the straight pipes of the calandria 1 are respectively arranged in the lower clamping groove 231. Wherein, calandria 1 is processed by aluminium pipeline.

In order to improve the stability of fixing the calandria 1, still include mount 5, mount 5 include with supporting beam 23 parallel arrangement hold the roof beam body 51 and be fixed in the connecting plate 52 that holds the roof beam body 51 both ends, hold the roof beam body 51 bottom surface and be equipped with a plurality of last draw-in grooves 511 that correspond joint matching with calandria 1, connecting plate 52 lateral wall is equipped with perforation 53, horizontal casing 2 front and back wall is close to both ends position and is equipped with the side opening 24 that corresponds with perforation 53 respectively, the bolt of side opening 24 and perforation 53 interior suit is used for fixing connecting plate 52 on horizontal casing 2 front and back wall.
