Heat storage tank

A heat storage tank, comprising:

• a tank body for thermally insulating and storing a fluid;
• a first pipe member defining an introduction passage communicating with the tank body, the introduction passage having a discharge port from which the fluid introduced through the introduction passage is injected into the tank body;
• a collision member disposed in the tank body, to which the fluid flowing from the discharge port collides;
• a second pipe member defining a discharge passage having an introduction port from which the fluid in the tank body is introduced to be discharged outside the tank body through the discharge passage, the introduction port being positioned in the tank body at a side opposite to the discharge port with respect to the collision member, wherein:
• the collision member includes a shield portion disposed opposite to the discharge port to be separated from the discharge port by a predetermined dimension, and a guide portion, extending from the shield portion to a side of the discharge port, for guiding the fluid flowing alone the shield portion toward a side of the discharge port;
• the discharge port is opened in an opening direction in the tank body;
• the shield portion extends in a direction approximately perpendicular to the opening direction of the discharge port;
• the guide portion extends from an entire outer peripheral end of the shield portion in a direction approximately parallel to the opening direction of the discharge port to cover the discharge port;
• and
• the guide portion is disposed to have a predetermined distance between the guide portion and the discharge port in a direction perpendicular to the opening direction of the discharge port;
• the heat storage tank further comprising:
• a mixture protection member disposed between the guide portion and an inner wall surface of the tank body, the mixture protection member having a plurality of through holes through which the fluid from the discharge port flows.

• the discharge port is opened in an opening direction in the tank body;
• the shield portion extends in a direction approximately perpendicular to the opening direction of the discharge port;
• the guide portion extends from an entire outer peripheral end of the shield portion to be tilted relative to the opening direction of the discharge port by a predetermined angle to cover the discharge port;

• and
• a shield portion disposed in the tank body, the shield portion including
• a collision wall surface with which fluid flowing out from the discharge port collides, the collision wall surface being disposed to face the discharge port and to be separated from the discharge port by a predetermined distance, and
• a guide wall surface extending from the collision wall surface for guiding the fluid after colliding with the collision wall surface such that the fluid after colliding with the collision wall surface is prevented from directly flowing toward the introduction port, wherein:
• the introduction port and the discharge port are positioned at both opposite sides relative to the shield portion;
• and
• the collision wall surface and the guide wall surface of the shield portion have a moment center (G) that is located at a position separated from the discharge passage.
