Description

TECHNICAL FIELD The present invention relates to a mounting structure for easily fixing an evaporator of a liquid cooler built in a water tank in the tank.

2. Description of the Related Art The evaporator of a conventional liquid cooler is fixed by a dedicated metal fixture, and the overflow is connected to the outside of the machine by a pipe installed above the water tank.

However, in the case of such a conventional liquid cooler, because the refrigerant pipe is connected with a dedicated mounting bracket, the mounting bracket interferes with the cleaning when cleaning the inside of the water tank. It has the disadvantage of being difficult.

Moreover, since only the refrigerant pipe is arranged in the water tank, there is a disadvantage that the temperature difference easily occurs in the water in the water tank.

Further, a space was required to separately fix the overflow pipe to the water tank.

Therefore, the present invention has been made in view of the above drawbacks of the prior art, and an object of the present invention is to provide a space-saving, temperature-difference-free, and easy-to-clean product.

Means for Solving the Problems That is, the present invention provides a casing, an elbow joined to the bottom of the casing, an overflow pipe screwed to the elbow and erected up to the vicinity of the ceiling, and loosely fitted to the pipe. A plate-shaped base, a cylinder having a height lower than the highest part of the pipe joined to the center of the base, and coaxial tubes inside and outside the cylinder are mounted, and an overflow pipe is further provided in the center. It consists of a plate-shaped lid with a through hole,
A large number of holes are bored in the lid inside the inner cylinder, the pipe is fitted in the lid for mounting the inner and outer cylinders, the outer cylinder is fitted to the base, and the inner cylinder is Two spaces are formed between the cylinders by placing them with a gap between them with the base, and by screwing and fixing to the pipe with a tightening tool from above the lid, and placing the evaporator in the spaces. This object is achieved by the mounting structure of the heat exchanger.

The outer cylinder is connected to a water supply pipe mounted in a box-shaped casing via a tube or the like.

Function In the heat exchanger mounting structure according to the present invention, three spaces are created by the cylinder mounted between the base on the plate and the lid.

And those spaces are respectively continuous at the upper side or the lower side, and when water is flowed through the tube connected to the outer cylinder,
Water first flows in the outermost space, and then flows to the middle part from above because it is continuous with the middle space.

Since the middle part and the inner space are continuous on the base side, they flow out toward the inner space, and the water that flows into the inner space overflows into the water tank from the many holes drilled in the lid. become.

Since the refrigerant pipes are arranged in the outer and middle spaces, the running water is gradually cooled by heat exchange, and when it overflows from the inner space to the water tank through the lid, it is mixed with a large number of holes to make it uniform. It becomes clear water.

Then, the water cooled to a certain temperature is supplied to another heat exchanger as a liquid refrigerant through the water supply joined to the water tank.

Further, when the water tank is temporarily filled with water, the water overflows from the hole at the tip of the overflow pipe fixing the refrigerant pipe.

Embodiment Hereinafter, the present invention will be described in detail according to an embodiment shown in the drawings.

Reference numeral 1 is a casing forming a box-shaped water tank, and a hole is formed in the bottom of the casing 1, and an elbow 2a is formed in the hole.
Are joined. The overflow pipe 2 is screwed into the elbow 2a.

The pipe 2 in the water tank is erected up to the upper part of the water tank, and the pedestal 3 is loosely fitted to the pipe 2 and placed on the bottom of the water tank.

A substantially disk-shaped base 4 loosely fitted to the pipe 2 is mounted on the mount 3.
Are joined.

A groove 5 is provided on the outer peripheral edge of the base 4 for abutting the cylinders, and an intermediate cylinder 6 is joined to the inside of the groove 5.

A refrigerant pipe 8 of the refrigeration cycle is provided around the inside and outside of the intermediate cylinder 6 through a hole provided in the base 4.

An outer cylinder 7 is fitted in the groove 5, and the base 4
Above the intermediate cylinder 6, an inner cylinder 11 is placed via a leg 10 joined to a base 9, and the height of the cylinder 11 is higher than that of the intermediate cylinder and is the same as that of the outer cylinder 7. It has become.

Above the inner and outer cylinders 7 and 11, there are a large number of holes 12 in the shape of a disk.
Is closed by a perforated lid 13. The lid 13 and the inner and outer cylinders 7 and 11 are joined by inserting the cylinders 7 and 11 into the groove 14 provided on the outer periphery of the lid 13 and the groove 15 provided in the middle, similarly to the base 4.

The lid 13 is engaged with a fastening tool 17 having a water flow diffusion plate 16 joined to the periphery of the threaded overflow pipe 2 by screwing.

Incidentally, as shown in FIG. 1, the water supply pipe 18 provided below the casing 1 forming the water tank and the outer cylinder are the pipes.
It is continuous through a tube 19 joined to 18.

Reference numerals 20 and 21 are lock nuts for fixing the inlet side and the outlet side of the refrigerant pipe 8 provided around the intermediate cylinder 6 to the casing 1, and 22 is water to be cooled in the water tank via a pump (not shown). A water distribution port for distributing water to the device, and 23 is a drainage pipe communicating with a hole 24 provided at the bottom of the water tank.

Further, 25 is a ball tap for supplying water from a water supply pipe (not shown) when the water in the water tank is low.

In the device according to the present invention having the above-described structure, the heat exchanger is fixed by screwing the fastening member 17 and the pipe 2 together. However, the water sent through the tube 19 is first transferred to the outer cylinder 7. The second cylinder adjacent to the intermediate cylinder 6 that is located above the intermediate cylinder 6 rises while gradually exchanging heat with the refrigerant flowing in the refrigerant pipe 8 spirally provided in the layer. The water flowing into the second layer descends while gradually exchanging heat with the refrigerant flowing through the refrigerant pipe 8 due to the fact that the water flows into the second layer due to the communication with the second layer.
After entering the inside and rising again, it blows out from the hole 12 drilled in the lid 13, is rectified by the water flow diffusion plate 16, and then enters the water tank outside the heat exchanger. The water in the water tank is distributed to the device to be cooled via the water distribution port 22.

Next, when cleaning the inside of the water tank, after draining the water in the water tank from the water draining pipe 23, the pipe 2 and the fastener 17
, The lid 13 is removed and the inner and outer cylinders 7, 11
Remove.

When the cylinder 11 is removed, the pipe 2 and the base 9 are no longer engaged,
Furthermore, when the engagement between the elbow 2a and the pipe 2 is released, the table 4 can freely move inside the water tank, so that the inside of the water tank can be thoroughly cleaned.

Effect As described above, since the heat exchanger mounting structure according to the present invention is configured to fix the heat exchanger with the overflow pipe, it is possible to provide a structure that does not occupy a space.

Further, the overflow pipe is fixed by screwing with the elbow joined to the bottom, and the overflow pipe and the tightening tool are fixed by screwing, so that the removal is easy and the pipe etc. can be removed easily. For example, the inside of the water tank can be easily cleaned.
