HEAT EXGHANGER WITH TUBE BUNDLES :~
The present invention relates to a heat ex hanger with tube bundles, partlcularly heat exchanger ~or maintaining the exit temperature of at least one flowing medium sub-stantially unifonm on lea~ing the heat exchangerO
Such heat exchangers with tube bundles are required in many processes in which the exit temperature o~ the fluid medium~ either the medium being passed through thQ tubes, or the medium passed around the tubes, has to be maintained ac~urately within a specific temperature range~ or a~ a specific temperature.
Such an exit temperature, howPver? is affected by at : least one of the following factors~
a~ change of the inlet temperature o the medium flow-ing abou~ the exchanger tubes;
b) change in quantity of the m~dium flowi~g about the exchanger tubes;
~: c) coating of the outer surfaces of the exchanger tubes; ~ :~
d3 change in temperature of the medium 10wing through the exchanger ~ubes; ~:
e) change in quantity of the mediwm flowing through the exchanger tubes; and f~ coating of the inner surfaces of the exchanger tubes.
In order to satisfy the pertaining requiremen~s 9 it is known to provide at least one tube, the so-called partial stre~m tube9 thro~gh ~hich a partial stream of the inflow-ing medium is passed, without a change of temperature, from the pertaining e.ntry cham~er to the pertaining exit cha~ber, whereby the fluid medlum is mixed in the exit cham~er with the remainder of the medium which has ex-perienced a temperature change by flowing through the other exchanger tubes. The partial stream passing through the partial stream tube is varied through movement of a gate member to obtain an adjusted tempexature (Mischtemperatur).
The maximum flow volume which can be passed through the par~ial st~e.am tube iS9 however~ limited by the pressure loss or drop which occurs whan the medium flows through the partial stream tube. Thîs pressure loss cannot exceed the pressure loss o the medi~ ich ~lows through ~he : other exchanger tubes, whereby the range of the adjusted temperature is limited as is the range o the e~it tempera-ture of ~he medi~m which flows about the exchanger tube~.

such heat exchangers. More particularly, i-t is an objert ,~
o~ khe in~ention to provide a hea~ exchanger in which with simple and economical technical means the amo~nt of flow-: ing medium passing through the partial stream tube and the exchanger tubes can be varled from zero to lOOV/o~ whereby ::
