Description

DETAILED DESCRIPTION OF THE INVENTION This invention is installed in the refrigerating chamber or freezing chamber of a refrigerator, and objects to be cooled are placed thereon.
Concerning coolers for use.

Refrigerators, especially household refrigerators, use forced air to blow cold air into the refrigerator, and the cold air cools the items placed inside the refrigerator. Many of them are of the type that is designed to be folded. In this type of refrigerator, the parts IJ and the objects to be cooled inside the refrigerator near the cold air outlet are easily exposed to cold air, and the further away from the cold air outlet, the more difficult it is for the liquid-cooled objects to be exposed to the cold air. ing. It takes a considerable amount of time to cool a workpiece to a uniform temperature.

An object of the present invention is to provide a refrigerator cooler that can uniformly cool a liquid-cooled object, thereby shortening the freezing time of a workpiece. be.

The refrigerator cold JJJ device according to the present invention has a roll bond panel having heat pipe working fluid passages bent to have an abbreviated cross section, and a horizontal wall for placing objects to be cooled and a vertical wall for absorbing cold air. A main body is formed, and fins and cold air passage holes are formed by cutting and raising the main body in a vertical wall.

According to this invention, when the cold air absorption vertical wall is exposed to cold air, since the vertical wall is formed with fins and cold air passage ports, the vertical wall is efficiently cooled by the fins, and the cold air passes through. It passes through the opening and directly hits the object to be cooled, which is placed on the horizontal wall for placing the object to be cooled.
Since the main body is formed of a roll bond panel that has a heat pipe working fluid passage, the entire main body is efficiently and uniformly cooled by the heat pipe effect, so that the object to be cooled is Coupled with the fact that the object is directly cooled by exposure to cold air, the object to be cooled can be efficiently and uniformly cooled in a short period of time.

Furthermore, since the main body is formed by bending the roll bond panels into an abbreviated shape, the manufacturing process is extremely intensive, and by cutting and raising the vertical walls themselves (twin (Because the fins and cold air passage ports are formed, there is no need for extra parts to form the fins and cold air passage ports.) Together with this, cold Ji is suitable for mass production.
ll+! :N can be done.

Embodiments of the present invention will be described below with reference to the drawings.

The refrigerator cooler comprises a main body (3) with a horizontal wall (5'f1) for the workpiece device and a vertical wall (2) for absorbing cold air. The main body (33) is formed by bending a 1-le bond panel into a cross-sectional shape.The bent portion is rounded.Horizontal wall (1)
On the vertical wall (2), there is an expanded tube portion (4) of a roll bond panel that is bulged out on the back side of each side and formed in a lattice shape in multiple rows and columns at predetermined intervals. This expansion tube portion (4) forms a heat 1-pipe working fluid passage. The working fluid such as Freon R12 or water is supplied to the expansion pipe section (
4) and is vacuum sealed by closing the injection port (55).

The vertical wall (2) has a large number of fins (6) and Cold air passage port (7
) is formed.

Although not shown in the drawings, the cooler is installed at 1) a point where cold air from a vaporizer of the refrigerator is blown out into the refrigerator. In this case, it is preferable that the vertical wall (2) is located further upstream of the cold air flow than the horizontal wall (1). The installation means C may be either a fixed type or a 1-lily J type that slides forward and pulls out the drawer.

Now, it is assumed that a cold N1 container is installed in the refrigerator as shown in (above), and 11 liquid cooling items (not shown) are placed on its horizontal wall (1)P.

The cold air contacts the fins (6) of the vertical wall (2) with 1 to efficiently cool the vertical wall (2), passes through the cold air passage port (7), and becomes liquid. It directly hits the cold IA object and cools it. When the vertical wall (2) is cooled, the heat is transferred to the horizontal wall (1) with small thermal resistance due to the heat pipe effect.
By moving to the vertical wall (2), the horizontal wall (1
) is rapidly cooled together with the vertical wall (2). As a result, the entire body (3) (and other parts) is cooled almost uniformly.

In this way, the heat of the object to be cooled is dissipated into the cold air, and the heat is transferred by contacting the horizontal wall (1), so that it is efficiently and uniformly cooled in 0 hours. .
