Two-phase immersion cooling device

A two-phase immersion cooling device comprising:

• an upper box body, a lower box body, heating elements and a condenser, the upper box body comprising a first side wall, a second side wall, a third side wall and a fourth side wall that are connected to each other from top to bottom;
• the first side wall, the second side wall, the third side wall and the fourth side wall jointly form a first cavity;
• the lower box body defining a second cavity;
• the second cavity is configured to contain coolant;
• a plurality of heating elements are disposed in the second cavity and immersing in the coolant;
• and the condenser comprising multiple rows and multiple columns of condensing tubes;
• wherein each rows and each columns of the condensing tubes are arranged from the first side wall to the third side wall or from the second side wall to the fourth side wall, and upward from bottom of the upper box body to fill the first cavity;
• and wherein the lower box body is detachably and hermetically connected to the bottom of the upper box body, an accommodating cavity is defined by the second cavity with the first cavity when the lower box body is connected to the upper box body;
• wherein the two-phase immersion cooling device further comprises a controller and a coolant management system, when a liquid level height of the coolant detected by a liquid level sensor is lower than a preset height, the controller controls the coolant management system to replenish the coolant into the accommodating cavity;
• wherein:
• the two-phase immersion cooling device further comprises, the controller is electrically connected to the liquid level sensor, an alarm, at least one condensing controller, at least one temperature sensor, at least one pressure sensor, at least one humidity sensor, at least one flow sensor, at least one fan, at least one safety valve controller, at least one pressure balance valve controller, and the coolant management system;
• and wherein when the liquid level height of the coolant detected by the liquid level sensor is lower than the preset height, the controller controls the alarm to output an alarm;
• and
• wherein:
• the coolant management system comprises an overflow weir plate, a liquid storage tank, a pump, a pipeline, a valve, and a filter, the pump, the pipeline, the valve, and the filter are in communication with the accommodating cavity outside or inside the lower box body.
