Benefits of technology

The present invention is a heat and mass transfer media arrangement for a direct heat exchanger. The arrangement includes a splash fill component that helps improve heat transfer efficiency. The splash fill component consists of two or more support plates and elongated bars that are positioned at specific locations and angles to create a more favorable flow of evaporative liquid, usually water, and air. The arrangement of the elongated bars is designed to improve the formation of drops and air flow through the arrangement, resulting in improved heat transfer. The elongated bars are usually angled from 5 to 45 degrees and exposing more of the evaporative liquid to the air, without impeding the air flow. The technical effects of this invention include improved heat transfer efficiency, reduced air resistance, improved water drops formation, and improved air flow direction.

Problems solved by technology

The cooling air which is usually drawn across the elongated bars by a fan causes some of the evaporative liquid to evaporate and thusly result in mass and heat transfer.

first embodiment

[0014]Referring now to FIG. 2, a splash fill arrangement is shown as comprising support plate 30 and elongated bars 32. The composition of support plate 30 and elongated bars 32 are as set forth above. However, elongated bars 32 are shown to be installed in support plate 30 at an angle to the horizontal. Such angle is preferably between 5 and 45 degrees. Such angled installation of elongated bars 32 is designed to improve the heat exchanging performance of the direct heat exchange system into which the splash fill arrangement is installed. Air flow is depicted as from left to right in FIG. 2 as shown by the arrow. Water flow is generally downward. This angled orientation of elongated bars 32 assists in exposing more of the evaporative liquid flowing across elongated bars 32 to the air moving across the splash fill arrangement, without unduly impeding the air flow.

second embodiment

[0015]Referring now to FIG. 3, a splash fill arrangement is shown as comprising support plate 40 and arrays of angled elongated bars 44 and array of horizontal elongated bars 46. Support plate 40 itself is seen to be hung or otherwise supported by support bars 42 which can be comprised of structural plastic, or aluminum or galvanized steel or stainless steel. The composition of support plate 40 and elongated bars 44 and 46 are as set forth above. However, elongated bars 44 in the upper array are shown to be installed in support plate 40 at an angle to the horizontal. Such angle is preferably between 5 and 45 degrees. Horizontal elongated bars 46 between the arrays of elongated bars 44 are seen to be installed at a zero degree angle to the horizontal. Such combined angled and horizontal installation of elongated bars 44 and 46, respectively, is designed to improve the heat exchanging performance of the direct heat exchange system into which the splash fill arrangement is installed.

third embodiment

[0018]Referring now to FIG. 4, a splash fill arrangement is shown as comprising support plate 50 and an inlet array of elongated bars 54, a central array of elongated bars 52 and an outlet array of elongated bars 56. The composition of support plate 50 and elongated bars 52, 54 and 56 are as set forth above. However, elongated bars 54 in the inlet array are shown to be installed in support plate 50 at an upward angle to the horizontal. Such angle is preferably between 5 and 45 degrees. Such angled installation of elongated bars 54 is designed to improve the heat exchanging performance of the direct heat exchange system into which the splash fill arrangement is installed by assisting in keeping more of the generally downward flowing water from exiting the splash fill arrangement through inlet side 57. Elongated bars 52 in the center array are seen to be installed at a downward degree angle to the horizontal. Such angle is preferably between 5 and 45 degrees. Elongated bars 56 in the ...

Abstract

A splash fill arrangement for use in a direct heat exchange section of a cooling tower is provided. Each splash fill arrangement includes support plates and elongated bars extending there between, which arrangement improves the performance of the splash fill arrangement when installed as a direct heat exchange section of a cooling tower. Certain of the elongated bars between the support plates are angled from the horizontal to improve the air flow capabilities and performance of the direct heat exchange section.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates to a heat and mass transfer media, or a splash fill arrangement, utilized within the direct heat exchange portion of a cooling tower. More particularly, the present invention relates to a splash fill arrangement for use in a direct heat exchange unit, which could be a cooling tower.[0002]The heat and mass transfer media, or splash fill arrangement, is generally horizontally oriented with an evaporative liquid, usually water, coursing over the arrangement, usually flowing downwardly, with an air stream directed usually transversely but potentially concurrent or cross current through the splash fill arrangement comprising a direct cooling section. The air interacts with the evaporative liquid for heat and mass transfer.SUMMARY OF THE INVENTION[0003]The heat and mass transfer media, or splash fill arrangement, of the present invention enhances the thermal efficiency of the direct heat exchanger by providing an arrangement o...
