Heat exchanger for a transformer
View Patent ↗A heat exchanger for a transformer including a heat exchanger medium, which can be introduced into a heat exchanger element via a feed element, and can be evacuated from the heat exchanging element via a discharge element. A first temperature measurement device measures a temperature of a feed flow of the heat exchanger medium and a second temperature measurement device measures a temperature of a discharge flow of the heat exchanger medium. A first opening is provided in the feed element, inside of which a first temperature probe is positioned at a predetermined location inside the feed flow during operation of the heat exchanger, and a second opening is provided in the discharge element, inside of which a second temperature probe is positioned at a predetermined location in the discharge flow during operation of the heat exchanger.
1. A heat exchanger for a transformer, comprising:
a heat exchanging element including:
a feed element having a first opening; and
a discharge element having a second opening, the heat exchanging element being configured for introducing a heat exchange medium feed current into the heat exchanging element via the feed element and discharging a heat exchange medium discharge current from the heat exchanging element via the discharge element;
a first temperature measurement device arranged in the first opening for insertion in the heat exchange medium feed current for measuring a temperature of the heat exchange medium feed current; and
a second temperature measurement device arranged in the second opening for insertion in the heat exchange medium discharge current for measuring a temperature of the heat exchange medium discharge current; and
a ventilation device disposed in the first opening.
2. The heat exchanger as claimed in claim 1 , comprising:
a ventilation device disposed in the second opening.
3. A heat exchanger for a transformer, comprising:
a heat exchanging element including:
a feed socket having a first opening; and
a discharge socket having a second opening, the heat exchanging element being configured for introducing a heat exchange medium feed current into the heat exchanging element via the feed socket and discharging a heat exchange medium discharge current from the heat exchanging element via the discharge socket;
a first temperature measurement device arranged in the first opening for insertion in the heat exchange medium feed current for measuring a temperature of the heat exchange medium feed current; and
a second temperature measurement device arranged in the second opening for insertion in the heat exchange medium discharge current for measuring a temperature of the heat exchange medium discharge current.
4. The heat exchanger as claimed in claim 3 , comprising:
a ventilation device disposed in the first opening.
5. The heat exchanger as claimed in claim 3 , comprising:
a ventilation device disposed in the second opening.
6. The heat exchanger as claimed in claim 3 , comprising:
a sealing element, arranged in each of the first opening and second opening for sealing the corresponding temperature measurement device in a heat-exchange medium-tight manner.
7. The heat exchanger as claimed in claim 3 , wherein the temperature measurement devices are thermocouples.
