Problems solved by technology

In general, a large amount of energy is required to generate such a jet, and in many cases the range of the jet cannot be sustained across the confines of the cargo hold
This can lead to uneven temperature distribution in the cargo compartment

Embodiment Construction

[0036] As described below, an air supply nozzle is provided that is capable of generating a wall fluid jet (i.e. an air jet disposed along one of the longitudinal boundaries along a solid) that lasts longer inside the housing than a free jet of the same fluid (i.e. An air jet without a solid boundary on any of its longitudinal sides) is significantly longer. The air supply nozzles utilize the Coanda effect and in the case of a Transport Refrigeration Unit (TRU) for a trailer of a truck or cargo carrier (or transport container), generate a wall jet by directing the fluid flow obliquely towards the roof of the trailer instead of A free jet formed by a substantially horizontal flow of fluid located only near the top plate. By slanting the wall jet in this way, the fluid flow tends to last longer inside the trailer, increasing the effective air injection capability of the TRU.

Abstract

An air supply nozzle is provided for fluid coupling with an end wall of a trailer, which is adjacent to a top wall of the trailer. The air supply nozzle includes a floor having a first curvature, a ceiling having a second curvature and sidewalls extending between the floor and the ceiling. The floor, ceiling and sidewalls are connectable with the trailer such that the ceiling is recessed from thetop wall. The first and second curvatures are configured such that fluid, which is flown through a pathway defined by the floor, ceiling and sidewalls, is directed toward a portion of the top wall.

Description

Background technique [0001] The subject matter disclosed herein relates to an air supply nozzle, and more particularly, to an angled air supply nozzle for introducing conditioned air into a cargo compartment. [0002] Many cargoes need to be transported in cargo holds that are supplied with conditioned air flow. Typically, this conditioned air is refrigerated, but it may also or alternatively be heated. In order to achieve an acceptable temperature uniformity within the cargo space, a jet of supply air is therefore generated which will ideally continue across the extent of the cargo space. Typically, a large amount of energy is required to generate such a jet, and in many cases the range of the jet cannot be sustained across the confines of the cargo bay. This can lead to uneven temperature distribution in the cargo compartment. Contents of the invention [0003] According to one aspect of the present disclosure, an air supply nozzle is provided for fluidly coupling with ...
