The present invention relates generally to transmission cooler thermal bypass device and more generally relates to a transmission cooler thermal bypass device that does not incorporate an actuator, spring valve, or flow control valve and contains fins for thermal cooling.
Transmission cooler thermal bypass devices are used with a transmission to create a flow path for receiving and transporting fluid from a heat source to a cooler. Once the fluid is cooled, the transmission cooler thermal bypass creates a path for receiving and transporting the fluid from the cooler to the heat source and/or gear box.

The present invention is illustrated and described herein with reference to the various drawings, in which like reference numbers denote like method steps and/or system components, respectively, and in which:
The present invention may be understood more readily by reference to the following detailed description of the invention taken in connection with the accompanying drawing figures, which form a part of this disclosure. It is to be understood that this invention is not limited to the specific devices, methods, conditions or parameters described and/or shown herein, and that the terminology used herein is for the purpose of describing particular embodiments by way of example only and is not intended to be limiting of the claimed invention. Any and all patents and other publications identified in this specification are incorporated by reference as though fully set forth herein.
Also, as used in the specification including the appended claims, the singular forms “a,” “an,” and “the” include the plural, and reference to a particular numerical value includes at least that particular value, unless the context clearly dictates otherwise. Ranges may be expressed herein as from “about” or “approximately” one particular value and/or to “about” or “approximately” another particular value. When such a range is expressed, another embodiment includes from the one particular value and/or to the other particular value. Similarly, when values are expressed as approximations, by use of the antecedent “about,” it will be understood that the particular value forms another embodiment.
Referring now specifically to the drawings, a transmission cooler thermal bypass device is illustrated in
Each opening (18, 20, 22, 24) is disposed within the body 12 of the transmission cooler thermal bypass device 10, and is specifically disposed on the first end and the second end of the body 12 of the transmission cooler thermal bypass device 10. The first passageway 14 and the second passageway 16 extend through the body 12 from the first end to the second end.
The first opening 18 fluidly communicates with a heat source, such as a valve body and receives fluid from the heat source. The second opening 20 fluidly communicates with the fluid cooler input for depositing fluid to the cooler. The third opening 22 fluidly communicates with the fluid cooler and receives cooled fluid from the fluid cooler. The fourth opening 24 fluidly communicates with the heat source, such as a gear box, and returns fluid cooled to the heat source. Each opening may be internally threaded for receiving a correspondingly threaded hose or engagement device.
As shown in
The body 12 and fins 26 are preferably composed of steel. As shown in
As shown in
The second passageway 16 extends from the first end to the second end of the body 12 and is angled upwards from the third opening 22 to the fourth opening 24. The third opening 22 and the fourth opening 24 are internally threated and an elongate second passageway 16 is formed within the body 12, extending from the first end to the second end of the body 12. The third opening 22 is disposed on the first end and the fourth opening 24 is disposed on the second end of the body 12. The third opening 22 and the fourth opening 24 are not positioned directly across from each other. Instead, the fourth opening 24 is positioned above or offset on the second end with respect to the location of the third opening on the third end, as shown in
The second passageway 16 extends in a straight line for a predetermined length from the third opening 22. After a predetermined length, the second passageway 16 is angled towards the fourth opening 24. If the fourth opening 24 is positioned on the second end at a location above the position of the third opening 22 on the first end, the second passageway 16 is angled upwards towards the fourth opening after the predetermined length.
The length of the bottom side of the body 12 is greater than the length of the top side of the body 12. Specifically, the first end of the body 12, adjacent the bottom side of the body 12, has a greater length than the length of the top side of the body 12. The first passageway 14 is entirely contained within the bottom side of the body 12, resulting in the length of the first passageway 14 being greater than the length of the second passageway 16. As a result in the differing lengths of the bottom side of the body 12 and the top side of the body 14, a shelf 28 is formed on the first end of the body 12. The shelf 28 is preferably adjacent the second opening 20. The shelf 28 is formed at the point on the body 12 where the length of the bottom portion of the body 12 extends outward, creating a portion of the body 12 with a greater length than the rest of the body 12. As shown in
The transmission cooler thermal bypass device 10 may have a body 12 that is not a solid piece, but is split into two sections. In other words, the body 12 of the transmission cooler thermal bypass device 10 may be a solid, integral piece, or may be split into two portions, a first portion and a second portion. The first portion contains at least one bore 34, and preferably two or more bores 34, while the second portion also contains at least one bore 34, and preferably two or more bores 34. An engagement mechanism, such as a bolt screw or the like, is inserted into the bores 34 for securing the first portion and the second portion. In this arrangement, the openings (18, 20, 22, 24) and the first passageway 14 and the second passageway 16 may be located within either the first portion or the second portion, or alternatively a portion of the openings (18, 20, 22, 24) and the first passageway 14 and the second passageway 16 are disposed within the first portion and the second portion and mating the first portion to the second portion forms the entire openings (18, 20, 22, 24) and the first passageway 14 and the second passageway 16.
Although the present invention has been illustrated and described herein with reference to preferred embodiments and specific examples thereof, it will be readily apparent to those of ordinary skill in the art that other embodiments and examples may perform similar functions and/or achieve like results. All such equivalent embodiments and examples are within the spirit and scope of the present invention and are intended to be covered by the following claims.
