<p>A system in a radio network node for regulating temperature of electronic equipment comprises the electronic equipment and a heat exchanger unit (200), comprising an evaporator unit (202), a condenser unit (203), and a first pipe (204). The first pipe (204) is arranged to connect the evaporator unit (202) and the condenser unit (203). A second fluid is flowable from the condenser unit (203) to the evaporator unit (202) in the first pipe (204). Furthermore, the system comprises a heater unit (201) arranged at the first pipe (204) and arranged to heat the second fluid in the first pipe (204) such that flow in the first pipe (204) is restricted. Furthermore, an arrangement (160) for restricting flow in a heat exchanger unit is provided.</p> |
