Embodiment 1

[0094] pass Figure 1 to Figure 3 Simulations were performed for the design of the plastic substrate 14 shown in . The result is expressed in Figure 1 to Figure 3 The plastic substrate 14 shown in has a reduction in maximum stress of greater than or equal to 35%, specifically greater than or equal to 45%, and even more specifically greater than or equal to 55% compared to the same plastic substrate without the raised portions 26, 34 . Figure 1 to Figure 3 The deformation of the plastic substrate 14 in the same plastic substrate without the raised portions 26, 34 is reduced by greater than or equal to 25%, specifically greater than or equal to 35%, even more specifically greater than or equal to 40%, and still more Specifically, greater than or equal to 44%.

Embodiment 2

[0096] use Image 6 and Figure 7 The gravity support center 100 shown in and using the same material as described in Example 1 figure 1 Simulations were performed using the plastic substrate 14 shown in . The results demonstrate that the bending moment is reduced, and thereby the rotation of the transformer 72 and the plastic substrate 14 is reduced. For example, a design with a center of gravity stand 100 and a plastic base 14 has the largest increase compared to the same plastic base without a center of gravity stand or a riser (i.e., with a stand that is flush with the bottom of the plastic base and no riser). The stress reduction is greater than or equal to 5%, specifically greater than or equal to 9%. The gravity support center 100 and plastic base 14 exhibit a 15% reduction in deformation, specifically greater than or equal to 20%, compared to the same plastic base without the gravity support center or risers (ie, a flat base).

Embodiment 3

[0098] pass Figure 11 Simulations were performed using the same material design as described in Example 1 shown in . the result shows Figure 11 The design shown in is the same as having a base with brackets but no height and no Figure 11 The design of the transformer attachment, compliant member, or cover extension member (e.g., bracket attachment to the base) has a maximum stress reduction of greater than or equal to 20%, specifically greater than or equal to 25%, more specifically greater than or equal to 27% compared to %, and even more specifically greater than or equal to 30%. Figure 11 The design shown in is the same as having a base with brackets but no height and no Figure 11 The design of the transformer attachment, compliant member, or cover extension member reduces deformation by greater than or equal to 25%, specifically greater than or equal to 30%, more specifically greater than or equal to 35%, even more specifically greater than or equal to 38% compared...

Abstract

A housing system may include a plastic cover (12); a plastic base (14) including a bottom (20) having side walls (22, 24); a first raised portion (26); a second raised portion (34) ); a first mounting post (40) located in the transformer end (32) of the plastic base (14) adjacent to the first side wall (22) of the long axis; a second mounting post (42) located adjacent to the second side of the long axis wall (22) in the transformer end (32) of the plastic base (14); wherein the first and second mounting posts (40, 42) have an amount greater than or equal to the raised wall (28, 36) in the Z direction A top surface (44) protruding from the bottom (20), wherein the top surface (44) is configured to receive a connecting element (46). The housing system may also include: a transformer (72) physically attached to the mounting post; a capacitor (74); a fan (78); and a printed circuit board (80).

Description

technical field [0001] An inverter housing system including stress and thermal management components therein is disclosed herein. Background technique [0002] Generally, an inverter is an electrical device that is connected to a power source and converts a portion of an input current (eg, converts direct current (DC) to alternating current (AC)) to provide power. The inverter can also convert a portion of the input current and store it in a storage device to use the storage device to supply power in the event of a power outage. Typically, an inverter is surrounded by a housing that protects the inverter components from damage, heat, or other external elements that could impair the function of the inverter. Inverter housings made of sheet metal with slots or perforations to dissipate internal heat by conduction or convection suffer from insufficient design freedom, which limits the possibility of enhancing aesthetics. Using metal for the inverter housing also increases the...
