Description
C F. BBAUN, OF SAN FBANCISCU, CALIFORNIA.
HEAT-EXCHANGER.
Specification of Letters Patent.
Patented Nov. 12, 1918.
Application filed September 18, 1916. Serial No. 120,675.
To all whom it ma concern:
Be it known t at I, CARL F. BRAUN, a citizen of the United States, residing in the city and county of San Francisco and State of California, have invented new and useful Improvements in Heat-Exchangers, of'
which the following is a specification.
This invention relates to heat exchangers for feed water heaters, oil coolers, and the like; and has for its object to simplify and improve the construction and operation of such devices.
Heat exchangers of the straight tube type employ chambered heads for the tubes which heretofore have unnecessarily restricted the number of tubes that could be attached thereto. These heads sometimes are of integral construction, while others have been made in twoparts, but in the latter instance the member to which the tubes are attached in the present device, wherein I employ a casing or shell to contain the cooling or heating medium, a nest of tubes within the shell for the circulation of the liquid to be cooled or heated, and chambered heads for the ends of said tubes, said heads comprising each a channeled member and a crosshead detachably connected together, the latter having the tubes secured thereto and made fiat to permit the insertion of a larger number of tubes for a given sized head wvithout interfering with the expanding and machining of the ends ofthe tubes and also to permit the use of brass in the cross head portion, whereby to overcome electrolysis. A further feature is the use of partition members in the heads, whereby to obtain a greater circulation of the liquid through the tubes.
One form which my invention may assume is exemplified in the following description and illustrated in the accompanying draw: ings, in which Figure 1 shows a longitudinal, central, sectional view of a device embodying my invention,
of tubes can be inserted in a Fig. 2 is a cross section on line 2-2 of Fig. 1.
Fig. 3 is a view of one end of the heating element.
Fig- 4 is a view of the opposite end of same.
Fig. 5 is a cross section on line 5-5 of Fig. 1.
In the drawing, I have shown a shell or casing 10, having an inlet 11 and a discharge orifice 12 and adapted to receive a cooling or heating medium, usually steam. Within the shell is a nest of tubes 13, fitted at one end into a stationary cross-head 14 bolted to flanges '15 on the casing, and at the other end fitted into a floating cross-head 16 carried within the casing and spaced therefrom. Cooperating with the stationary head is a chambered or channeled member 17 also bolted to the flange 15 and provided with an inlet 18 and an outlet 19 for the liquid which is to be treated. The channeled member 17 has radial webs or vanes 20 forming partition members which rest against the head 14 and segregate the tubes at this end into a plurality of sectors, five in the present instance.
Cooperating with the floating head 16 is a chambered or channeled member 21. secured thereto by means of stud bolts 22 and establishing communication between the ends of adjacent tubes. The channeled member 21 also is provided with partition members 23, four being shown, which are staggered with respect to the partitions 20, so that the liquid in passing from inlet to outlet is compelled to follow a back and forth movement a plurality of times whereby to increase the efliciency of the device.
A removable end 24 is bolted to a flange 25 on the casing and incloses the floating head of the tubes. Stud bolts 26 are shown as projecting from each ofthe cross-heads through the adjacent channeled member.
In the device shown and described both ends of the tubes are fitted into cross-heads which are entirely flat and fully exposed when the channeled members are removed and, therefore, the expanding of the ends of the tubes is greatly facilitated and simplified. Moreover, an opportunity is afforded for arranging the tubes closer together and nearer to the rim of the channeled members, and thereby a larger number iven sized head. Furthermore, I am enab ed, on acfore, they can be instantly cleaned. The
efficiency of the device is further increased by the provision of the partition members which cause the liquid to pass back and forth a plurality of times in its movement from inlet to outlet. A series of partltion members, if formed upon the portion of the.
head to which the tubes are attached, would interfere with the insertion of expanding tools and otherwise limit the number of tubes employed in a given sized head. However, by forming these partition members on the removable channeled members the cross-head plates are left open and exposed for the purpose of inserting the tubes and expanding their ends.
' The present construction is applicable to fluid heaters, coolers, condensers, evaporators and the like.
The shell 10 has apertured brackets 30 for the purpose of receiving supporting means such as legs or feet and cross head 16 preferably has a part 31 which engages the bottom of the shell to support the cross head in the position shown in Fig. 1 so that upon removal of-end 24 the cross head will be held against downward movement.
Having thus described my invention, what I claim and desire to secure by Let 'ters Patent is 1. In a heat exchanger, a shell having its ends flanged outwardly, a stationary cross head abutting one of the shell flanges, a floating cross head disposed beyondthe opposite end of the shell, a nest of tubes fitted at their ends in said cross heads, a chammesses therein, a removable end inclosing said memher and abutting the other shell flange, a chambered member abutting the stationary cross head and having an inlet and an outlet with a series of cross partitions one of which separates the inlet and outlet, means to simultaneously bolt the last named chambered member and the stationary cross head to the first named shell flange whereby upon removal of the last named member the stationary cross head will be exposed throughout its area, and means to removably bolt the chambered member of the floating cross head to the latter whereby upon removal of the last named member the floating cross head will be exposed throughout its area.
2. In a heat exchanger, a shell, a stationary cross head located beyond and abutting one end of the shell, a floating cross head at the opposite end of the shell, a nest of tubes fitted at their ends in said cross heads,-
a chambered member abutting the floating cross head and having a series of cross partitions therein, a removable end inclosing said member and secured to the said opposite end of the shell, a chambered member abutting the stationary cross head and having an inlet and an outlet located side by side and also a series of cross partitions one of which latter separates the inlet and outlet, means to removably secure the last named chambered member to the stationary cross head, and means to removably secure the chambered member of the floating cross head to the latter.
In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
CARL F. BRAUN.
