Abstract
The cooling and/or heating of drive and/or transmission units of construction machines and similar equipment is disclosed. A temperature control device can cool and/or heat such drive and/or transmission units. The temperature control device can include a heat exchanger module having a liquid jacket through which flow is possible. The heat exchanger module can form a ring body for fitting in a sandwich-like manner between two transmission and/or drive sections. The ring body can have a central through-cutout for a drive element to pass through and can have on each opposite end face a connection flange for precision-fit end-face connection to the two transmission and/or drive sections.
Claims20
A temperature control device for cooling and/or heating a tunnel borer transmission, the temperature control device comprising:
- a heat exchanger module having a liquid jacket and radially mutually offset turbulence fins in a ring chamber,
- wherein the heat exchanger module comprises a ring body for fitting in a sandwich-like manner between two adjacent drive and/or transmission sections,
- wherein the ring body has a central through-cutout for the guiding of a rotatable drive and/or transmission element,
- wherein the ring body has on opposite end faces a connection flange such that the ring body comprises two opposite connection flanges for end-face connection to the two adjacent transmission and/or drive sections, and
- wherein the radially mutually offset turbulence fins alternately project outwardly from an inner circumference of the ring chamber and inwardly from an outer circumference of the ring chamber, and alternately define at the inner circumference and at the outer circumference of the ring chamber a passage gap for a temperature control liquid to be circulated.
A temperature control device for cooling and/or heating a tunnel borer transmission, the temperature control device comprising:
- a heat exchanger module having a liquid jacket,
- wherein the heat exchanger module comprises a ring body for fitting in a sandwich-like manner between two adjacent drive and/or transmission sections,
- wherein the ring body has a central through-cutout for the guiding of a rotatable drive and/or transmission element,
- wherein the ring body has on opposite end faces a connection flange such that the ring body comprises two opposite connection flanges for end-face connection to the two adjacent transmission and/or drive sections, and
- wherein the ring body has a solid outer ring on which the two opposite connection flanges are configured, an inner ring arranged inside the solid outer ring, and two flat end walls which connect the solid outer ring and the inner ring to one another and delimit the liquid jacket between them.
A temperature control device for cooling and/or heating a tunnel borer transmission, the temperature control device comprising:
- a heat exchanger module having a liquid jacket,
- wherein the heat exchanger module comprises a ring body for fitting in a sandwich-like manner between two adjacent drive and/or transmission sections,
- wherein the ring body has a central through-cutout for the guiding of a rotatable drive and/or transmission element,
- wherein the ring body has on opposite end faces a connection flange such that the ring body comprises two opposite connection flanges for end-face connection to the two adjacent transmission and/or drive sections, and
- wherein an outer ring has axial through-cutouts within the two opposite connection flanges for flow connection of the two adjacent transmission and/or drive sections, between which the heat exchanger module is arranged in a sandwich-like manner.
