Problems solved by technology

If the conveyor starts to operate from this state, the cold cooling water from the outdoor piping will flow into the indoor piping, so condensation will occur on the indoor piping and equipment due to temperature differences, humidity, and other conditions.
There is also the possibility of thermal shock on the substrate parts due to a sharp temperature drop

no. 1 Embodiment approach

[0024] [structure]

[0025] figure 1 It is a block diagram showing an example of the transmission system according to the first embodiment. This transport system includes a conveyor 11 , a pump rack 12 and a heat exchanger 13 . The conveyor 11 and the pump rack 12 are installed indoors, and the heat exchanger 13 is installed outdoors.

[0026] The conveyor 11 , the pump frame 12 and the heat exchanger 13 are connected by a pipe 14 filled with cooling water 15 . For the cooling water 15 , for example, antifreeze is used in order to prevent clogging of flow paths and damage to pipes due to freezing.

[0027] The conveyor 11 includes a control unit 20 . The control unit 20 circulates the cooling water through the drive of the heat exchanger 13 and the pump frame 12 during the operation of the conveyor 11 . The control unit 20 stops the circulation of the cooling water generated by the drive of the heat exchanger 13 and the pump frame 12 when the conveyor 11 is stopped.

no. 2 Embodiment approach

[0040] [structure]

[0041] Figure 4 as well as Figure 5 An example of the transmission system according to the second embodiment is shown. In these figures, with figure 1 The difference is that the heat storage member 16 is accommodated inside the tank 18 . The heat storage member 16 is, for example, Figure 4 A spherical shape as shown can be contained in a container. Alternatively, the thermal storage member 16 is Figure 5 It can be wrapped in a container in the form of a sheet as shown.

[0042] [effect]

[0043] The conveyor 11, the pump stand 12, the heat exchanger 13, the piping 14, and the cooling water 15 function in the same manner as in the first embodiment. The heat storage member 16 is in direct contact with the cooling water stored in the tank 18 , and recovers the heat of the conveyor 11 that has taken the cooling water 15 . Similar to the first embodiment, the heat storage member 16 changes from a solid to a liquid at a preset melting point, and sto...

no. 3 Embodiment approach

[0046] [structure]

[0047] Image 6 It is a block diagram showing an example of the transmission system according to the third embodiment. and figure 1 The difference is that the tank 18 is removed and the heat storage member 16 is installed on the surface of the outdoor piping 14 . The heat storage member 16 includes a pair of electrodes 21 . The control unit 20 is able to apply a voltage to the heat storage member 16 via the electrodes 21 .

[0048] [effect]

[0049] The conveyor 11, the pump stand 12, the heat exchanger 13, the piping 14, and the cooling water 15 function in the same manner as in the first embodiment. The heat storage member 16 attached to the piping 14 outdoors recovers the heat of the conveyor 11 that has received the cooling water 15 via the piping 14 . The heat storage member 16 changes from a solid to a liquid at a predetermined melting point, and stores heat generated by the conveyor 11 as latent heat.

Abstract

According to an embodiment, the transport system includes a conveyor having a heat generating unit that generates heat during operation. In addition, the transmission system includes a pump unit, a control unit, a tank, and a heat storage member. The pump section circulates cooling water through the conveyor. The control unit drives the pump unit to circulate the cooling water during the operation of the conveyor, and stops the circulation of the cooling water when the conveyor is stopped. The tank stores the cooling water circulated by the conveyor through the external piping, and supplies it to the pump unit. The heat storage member is provided on the surface of the tank, and stores waste heat of the heat generating part taken into the cooling water through the tank. Then, the heat storage member undergoes a phase transition when the cooling water in the tank is lower than a predetermined temperature, and the cooling water in the tank is heated by the generated latent heat.

Description

technical field [0001] Embodiments of the present invention relate to a transmission system that transmits, for example, radio waves for television broadcasting by a water-cooled transmission machine. Background technique [0002] There are water-cooled and air-cooled transmission systems for TV broadcasting. Since the water-cooling method has higher cooling efficiency than the air-cooling method, it has the advantages of suppressing space and being able to reduce noise. [0003] A general water-cooled TV transmitter system includes a transmitter connected by piping, a pump frame, and a heat exchanger. Conveyors and pump racks are located indoors and heat exchangers are located outdoors. Cooling water circulates inside the equipment. Cooling water is sent from the pump frame to the conveyor to cool the heat generating part of the conveyor. Also, the cooling water is cooled by the heat exchanger and returned to the pump frame. [0004] The circulation of the cooling wate...
