Abstract
The present disclosure relates to an improved convector comprised of a housing having an inlet and an outlet, first and second heating elements which are diagonally offset from one another and an internal wall positioned at an upper end of the convector. The positioning of the first and second elements allows for maximizing heat output of the convector while minimizing its overall width. Meanwhile, the internal wall positioned at an upper end of the convector allows for the redirection of heat towards the rear wall of the convector, thereby limiting the amount of heat that would otherwise accumulate at a lower end of the output of the convector.
Description
IMPROVED CONVECTOR
FIELD
The present invention relates to convectors, and more specifically to improved convectors with strategically-positioned heating elements.
BACKGROUND
The field of heaters and more specifically of convectors have undergone significant changes in the past few years. Specifically, regulations have been put in place in order to limit the heat generated from a specific aluminium heating element, whereas previously the relevant regulation in place only regulated the total heating output of the convector. As such, when considering new convectors, the temperature of the heating elements must be considered above and beyond the overall temperature of the convector. For instance, in Canada it has been determined by CSA that the maximum temperature output for an aluminium heating element must be 280 degrees Celsius.
In order to meet these new demands, fabricators were required to lower the densities of the heating elements. By lowering their densities, the outputs were reduced; however, to maintain an acceptable level of heat output from the convectors, convectors with one heating element (which would previously give the required output) necessarily had to be changed to convectors with two or more heating elements. In an alternative embodiment, the length of the convector could be increased (as intensity is a factor of power per unit area); however, it is not desirable to have overly long convectors. As such and by way of example, in order to provide a 2000W
convector, rather than having a single 2000W heating element, two 1000W heating elements were utilized to provide the same output while having a heating element density reduction.
Unfortunately, by adding a second heating element beside the first heating element in the convectors, the depth of those convectors was greatly increased, to the detriment of the owner who typically desires convectors which are as compact as possible. Therefore, it is an objective of the present disclosure to reduce the depth of the convector, thereby changing the positioning of the heating elements which are positioned within the convector. In doing so, testing was conducted to find the optimal positioning of the first and second heating elements, both to minimize the depth of the convector while maximizing its heating output.
SUMMARY
In one aspect, the present disclosure provides an improved convector comprising a housing comprised of an inlet and an outlet to provide airflow circulation within the convector and an internal wall positioned within and proximate an upper end of the housing to limit heat at the upper end of the convector. The improved convector also has a first X-shaped heating element positioned within and proximate a lower end of the housing to provide a first source of heat and a second X-shaped heating element positioned within the housing and diagonally offset from the first X-shaped heating element to provide a second source of heat wherein the configuration of the first and second X-shaped heating elements optimizes the heating power and minimizes the depth of the convector.

4 DETAILED DESCRIPTION OF THE DRAWINGS
The following embodiments are merely illustrative and are not intended to be limiting. It will be appreciated that various modifications and/or alterations to the embodiments described herein may be made without departing from the disclosure and any modifications and/or alterations are within the scope of the contemplated disclosure.
With reference to Figure 1A, 1B and 2 and according to an embodiment of the present disclosure, an improved convector 10 to provide a heating means for a room is shown, generally comprised of a housing 15 comprised of an inlet 20 and an outlet 22 to provide airflow circulation within the convector 10, an internal wall 25 positioned within the housing 15 to limit heat at an upper end 30 of the convector 10, a first X-shaped heating element 35 positioned within and proximate a lower end 40 of the housing 15 to provide a first source of heat and a second X-shaped element 37 positioned within the housing 15 and diagonally offset from the first X-shaped heating element 35 to provide a second source of heat. The internal wall 25 is shown positioned at the upper end 30 of the convector 10, and the internal wall 25 is nearly perpendicular to the plane of the front wall 45 of the housing 15. As heat rises to the upper end 30 of the convector 10, the internal wall 25 will divert some of the heat towards the rear wall 50 of the convector 10 in order to limit an overflow of heat accumulating at the upper end 30 of the convector 10. In a preferred embodiment, the internal wall 25 in combination with a top wall 27 create a cavity, which in this embodiment is L-shaped. In turn, the cavity creates a thermal barrier in order to limit heating accumulating at the upper end 30 of the convector 10. The first and second heating elements 35, 37 are preferably constructed of aluminum, and further comprised of a center cylindrical heating member 60, having multiple X-shaped wings 65 projecting therefrom. The first and second heating elements 35, 37 are preferably comprised of a sand-blasted surface in order to increase the contact surface of the heating elements 35, 37 with air and limit the heat radiation of the heating member 60 towards the wings 65. Together, these result in a better convection heat transfer and helps direct air towards the outlet 22 of the convector 10. The first and second heating elements 35, 37 are positioned within the housing 10 and connected thereto by means of first and second internal parallel brackets 70, 72. First and second internal brackets 70, 72 are comprised of apertures (not shown) which receive the heating member 60 of each first and second heating elements 35, 37 therein. An optional controller 75 is also shown, positioned at the upper end 30 of the convector 10 which allows for a user to change the temperature and other parameters of the convector 10.
With reference to Figures 2, 3 and 4A and according to an embodiment of the present disclosure, the first and second heating elements 35, 37 are preferably positioned proximate a lower end 40 of the housing 15 of the convector 10. As shown, the second heating element 37 is diagonally offset from the first heating element 35 in order to optimize the heating power of the convector 10 while minimizing the overall depth of the convector 10. A worker skilled in the art will appreciate that it is an advantageous to have a thinner convector 10 in the market, while maintaining optimal heating levels. In this preferred embodiment, the cylindrical heating member 60 of the first X-shaped heating element 35 is positioned 2.5" from the lower wall 80 of the housing 10 and 1.0"
from the front wall 45 of the housing 15, while the second X-shaped heating element 37 is positioned 5.5" from the lower wall 80 of the housing 15 and 1.5" from the front wall 45 of the housing 15.
With reference to Figures 4A, 4B and 4C and according to an embodiment of the present disclosure, the first X-shaped heating element 35 is shown comprised of a heating member 60 and X-shaped wings 65 projecting from the heating member 60. The optimal height of the heating element 35 is approximately 108mm, while the depth is approximately 33mm.
Meanwhile the optimal angle as shown in Figure 4C specifically is between 80-85 degrees.
Such dimensions of the heating element 35 have been shown to provide the appropriate amount of heating output to satisfy the constraints as previously mentioned, while optimizing output and minimizing convector depth.
With reference to Figure 5 and according to an embodiment of the present disclosure, the upper end 30 of the outlet 22 of the convector (not shown) is shown in greater detail. As explained, the internal wall 25 together with the top wall 27 create a cavity 90 which is generally L-shaped. The cavity 90 is positioned at the upper end 30 of the outlet 22 and provides a thermal barrier such that hot air flowing upwardly from the first and second heating elements (not shown) does not accumulate at an upper end 30 of the outlet 22.
With reference to Figure 6 and according to another embodiment of the present disclosure, the convector 210 is shown without the front wall. However, a secondary insulating wall 229 is shown, positioned behind the front wall (not shown). The insulating wall 229 is necessary in convectors which output at least 2000W, as the additional heating generated may overheat the front wall (not shown). Said insulating wall 229 is conversely simply optional in other lower power output models. In this embodiment, the dimensions of the convector 210 were minimized and are approximately 18" x 35" x 2.5".
With reference to Figure 7, and according to an embodiment of the present disclosure, a computer simulation of the heat transfer of the convector 10 is shown in detail. As shown, the heat at the rear wall 50 of the upper end 30 of the convector 10 is minimized and the bulk of the heat from both the first and second heating elements 35, 37 moves upwardly and out of the outlet 22. Further, this is very little heat emanating from the front wall 45 of the convector 10.
With reference to Figures 8, 9, 10 and 11 and according to another embodiment of the present disclosure, alternative positions of the first and second heating elements are shown. These alternative positions still provide that the heating elements are diagonally offset one from the other and provide heating to the outlet of the convector.
The following embodiments are merely illustrative and are not intended to be limiting. It will be appreciated that various modifications and/or alterations to the embodiments described herein may be made without departing from the disclosure and any modifications and/or alterations are within the scope of the contemplated disclosure.
With reference to Figure 1A, 1B and 2 and according to an embodiment of the present disclosure, an improved convector 10 to provide a heating means for a room is shown, generally comprised of a housing 15 comprised of an inlet 20 and an outlet 22 to provide airflow circulation within the convector 10, an internal wall 25 positioned within the housing 15 to limit heat at an upper end 30 of the convector 10, a first X-shaped heating element 35 positioned within and proximate a lower end 40 of the housing 15 to provide a first source of heat and a second X-shaped element 37 positioned within the housing 15 and diagonally offset from the first X-shaped heating element 35 to provide a second source of heat. The internal wall 25 is shown positioned at the upper end 30 of the convector 10, and the internal wall 25 is nearly perpendicular to the plane of the front wall 45 of the housing 15. As heat rises to the upper end 30 of the convector 10, the internal wall 25 will divert some of the heat towards the rear wall 50 of the convector 10 in order to limit an overflow of heat accumulating at the upper end 30 of the convector 10. In a preferred embodiment, the internal wall 25 in combination with a top wall 27 create a cavity, which in this embodiment is L-shaped. In turn, the cavity creates a thermal barrier in order to limit heating accumulating at the upper end 30 of the convector 10. The first and second heating elements 35, 37 are preferably constructed of aluminum, and further comprised of a center cylindrical heating member 60, having multiple X-shaped wings 65 projecting therefrom. The first and second heating elements 35, 37 are preferably comprised of a sand-blasted surface in order to increase the contact surface of the heating elements 35, 37 with air and limit the heat radiation of the heating member 60 towards the wings 65. Together, these result in a better convection heat transfer and helps direct air towards the outlet 22 of the convector 10. The first and second heating elements 35, 37 are positioned within the housing 10 and connected thereto by means of first and second internal parallel brackets 70, 72. First and second internal brackets 70, 72 are comprised of apertures (not shown) which receive the heating member 60 of each first and second heating elements 35, 37 therein. An optional controller 75 is also shown, positioned at the upper end 30 of the convector 10 which allows for a user to change the temperature and other parameters of the convector 10.
With reference to Figures 2, 3 and 4A and according to an embodiment of the present disclosure, the first and second heating elements 35, 37 are preferably positioned proximate a lower end 40 of the housing 15 of the convector 10. As shown, the second heating element 37 is diagonally offset from the first heating element 35 in order to optimize the heating power of the convector 10 while minimizing the overall depth of the convector 10. A worker skilled in the art will appreciate that it is an advantageous to have a thinner convector 10 in the market, while maintaining optimal heating levels. In this preferred embodiment, the cylindrical heating member 60 of the first X-shaped heating element 35 is positioned 2.5" from the lower wall 80 of the housing 10 and 1.0"
from the front wall 45 of the housing 15, while the second X-shaped heating element 37 is positioned 5.5" from the lower wall 80 of the housing 15 and 1.5" from the front wall 45 of the housing 15.
With reference to Figures 4A, 4B and 4C and according to an embodiment of the present disclosure, the first X-shaped heating element 35 is shown comprised of a heating member 60 and X-shaped wings 65 projecting from the heating member 60. The optimal height of the heating element 35 is approximately 108mm, while the depth is approximately 33mm.
Meanwhile the optimal angle as shown in Figure 4C specifically is between 80-85 degrees.
Such dimensions of the heating element 35 have been shown to provide the appropriate amount of heating output to satisfy the constraints as previously mentioned, while optimizing output and minimizing convector depth.
With reference to Figure 5 and according to an embodiment of the present disclosure, the upper end 30 of the outlet 22 of the convector (not shown) is shown in greater detail. As explained, the internal wall 25 together with the top wall 27 create a cavity 90 which is generally L-shaped. The cavity 90 is positioned at the upper end 30 of the outlet 22 and provides a thermal barrier such that hot air flowing upwardly from the first and second heating elements (not shown) does not accumulate at an upper end 30 of the outlet 22.
With reference to Figure 6 and according to another embodiment of the present disclosure, the convector 210 is shown without the front wall. However, a secondary insulating wall 229 is shown, positioned behind the front wall (not shown). The insulating wall 229 is necessary in convectors which output at least 2000W, as the additional heating generated may overheat the front wall (not shown). Said insulating wall 229 is conversely simply optional in other lower power output models. In this embodiment, the dimensions of the convector 210 were minimized and are approximately 18" x 35" x 2.5".
With reference to Figure 7, and according to an embodiment of the present disclosure, a computer simulation of the heat transfer of the convector 10 is shown in detail. As shown, the heat at the rear wall 50 of the upper end 30 of the convector 10 is minimized and the bulk of the heat from both the first and second heating elements 35, 37 moves upwardly and out of the outlet 22. Further, this is very little heat emanating from the front wall 45 of the convector 10.
With reference to Figures 8, 9, 10 and 11 and according to another embodiment of the present disclosure, alternative positions of the first and second heating elements are shown. These alternative positions still provide that the heating elements are diagonally offset one from the other and provide heating to the outlet of the convector.
