The present invention relates to a cold water circulating and supplying device for a mat, and more particularly, to a cold water circulating and supplying device for a mat, which is less bulky than a cold water circulating device using a refrigeration cycle and has less vibration and noise, .

Generally, the hot water mat is largely composed of a mat body, a hot water boiler and a circulating hose, as disclosed in the prior art of Patent Application No. 10-2009-0021259.

6, a plurality of heat exchanging units 130 are disposed in parallel in the first direction in the first receiving space 111 of the case 110, And the thermal energy of the fluid passing through the heat exchanging part 130 is absorbed by the axial coolant of the compressor 142 to cool the fluid.

The plurality of heat exchanging units 130 are guided in a first direction along guide units 135 inserted into guide grooves (not shown) provided at one side. Therefore, the thermal exchange between the heat exchanging part 130 and the compression cartridge 140 can be prevented from being caused by the thermal deformation of the compression cylinder 140, thereby reducing the heat exchange efficiency. Since the heat exchanging unit 130 and the compression cartridge 140 are in close contact with each other by the elastic member 118 interposed between the inner wall surface of the case 110 and the heat exchanging unit 130, The heat exchange efficiency of the compression cooling cartridge 140 can be improved.

Since the water pump 150 and the control unit 160 accommodated in the case 110 and supplied with power are separately housed in the second accommodation space 112 and the third accommodation space 113 as described above, It is possible to minimize the risk of electric shock accidents that may occur in the process of attaching and detaching the spark-discharging cartridge 140 from the space 111.

7 and 8, the storage tank 120 is connected to the discharge side end portion P2 of the cooling mat pipe P through the inflow pipe 121 so that the fluid that has passed through the cooling mat is discharged to the storage tank 120 into the storage space inside. The fluid stored in the storage space is supplied to the water inlet 132 of the heat exchanger 130 at a predetermined pressure by driving the water pump 150. The fluid supplied to the water inlet 132 flows into the fluid passage 131, The cooling fluid is cooled by the heat exchange with the cooling cylinder 140 adhered to the side surface of the heat exchanging part 130 in the course of passing the cooling water M through the water outlet 133, (P1).

A plurality of heat exchange units 130 and a plurality of thermal compression cartridges 140 are alternately arranged and the fluid transfer passages 131 provided in the plurality of heat exchange units 130 are connected to each other. It is possible to sufficiently secure the time and area for the operation. Since the heat insulating material 116 is provided on the wall surface of the inside of the first accommodating space 111 of the case 110, it is possible to prevent the cold air from the hot-storing cartridge 140 from being lost to the outside of the case 110.

Particularly, since the heat exchanging part 130 is pressed by the elastic member 118 interposed between the inner wall surface of the case 110 and the heat exchanging part 130 in the direction in which the heat exchanging part 130 is in tight contact with the compression cooling cartridge 140, And the heat exchanging part 130 are spaced apart from each other to prevent the heat exchange efficiency from being lowered.

In addition, the plurality of heat exchanging units 130 are disposed in the first accommodating space 111 by the guide unit 135 so as to be movable in the first direction. Therefore, even if the thickness of the compression cylinder 140 is changed by thermal deformation, the close contact between the heat exchange units 130 and the compression cylinder 140 can be maintained.

Here, the driving of the water pump 150 can be controlled through the control unit 160 (see FIG. 6). Specifically, the control unit 160 uses a value obtained from at least one of a temperature sensor (not shown) for measuring the temperature of the fluid and a timer (not shown) for controlling the driving period of the water pump 150, (Not shown) that measures the level of the fluid stored in the storage tank 120. The fluid level of the fluid in the reservoir tank 120 is controlled by the fluid level sensor 150, To the user, thereby improving the usability.

9, the lid 117 is removed from the case 110, and the heat exchanging unit 130 is disposed in the first accommodating space 111. In this case, The cooling cylinder 140 is pulled out of the space between the heat exchanging units 130 and then inserted into the space separated between the heat exchanging units 130 again to freeze the freezing cartridge 140. [ Can be exchanged. Since the plurality of heat exchanging units 130 are movable in the first direction and the elastic members 118 are disposed between the heat exchanging unit 130 and the inner wall surface of the case 110, 130 can be enlarged to facilitate insertion and detachment of the compression cartridge 140.

According to the present embodiment as described above, since it is not necessary to provide a separate refrigeration cycle in the cooling device for cooling the fluid passing through the cold water mat, the volume is smaller than that of the cold water circulation supply device using the conventional refrigeration cycle, It is possible to improve the usability because the noise is small.

Further, since the fluid is allowed to pass through the heat exchanging portion and the sufficient time and area are provided for heat exchange with the compression cartridge, the cooling performance is excellent and the heat exchange portion and the compression cartridge are maintained in close contact with each other.

The scope of the present invention is not limited to the above-described embodiments, but may be embodied in various forms of embodiments within the scope of the appended claims. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims.
