Detailed Description

The following detailed description of preferred embodiments of the utility model is made in connection with the accompanying drawings, which form a part hereof, and together with the description of the embodiments of the utility model, are used to explain the principles of the utility model and are not intended to limit the scope of the utility model.

Referring to fig. 1 to 6, the present utility model provides a cold water tank, comprising a tank body 100 and an anti-freezing assembly 200; the top of the case 100 is provided with a through hole 110; the antifreeze assembly 200 includes a heat transfer pipe 210 and a heat generating pipe 220, one end of the heat transfer pipe 210 is connected to the through hole 110, one end of the heat generating pipe 220 extends into the heat transfer pipe 210 along the through hole 110, the other end of the heat generating pipe 220 is closed to the through hole 110, and the closed end of the heat transfer pipe 210 extends toward the inner bottom of the case 100.

When in use, one end of the heating tube 220 is inserted into the heat transfer tube 210 along the through hole 110, and the heat of the heating tube 220 is stored in the heat transfer tube 210 and then is transferred into the box 100 through the outer wall of the heat transfer tube 210, so that the box 100 is always below the freezing point to avoid freezing. Because of the smaller volume of the heat transfer tube 210, it does not occupy more volume inside the case 100. The heat source of the heat pipe 220 may be externally connected to a power source, or a battery compartment may be provided in the heat pipe 220, and a mobile battery may be filled therein to supply electric power. The specific use time of the heating tube 220 can be used as a reference, and the heating tube is not required to be started every day and all the day, so that the electric energy can be effectively saved.

In order to facilitate filling cooling water and checking the situation in the box 100, in an embodiment of the utility model, a feed inlet 120 is provided on one side of the top of the box 100, and a cover plate 130 capable of being opened and closed is hinged to the feed inlet 120. Specifically, cooling water can enter through the feed inlet 120, and a rubber ring is embedded at the joint of the cover plate 130 and the feed inlet 120, so that the tightness is improved.

In order to enable the cooling chamber to freely access, in an embodiment of the utility model, a water outlet pipe 140 is connected to one side of the outer wall of the case 100, and the water outlet pipe 140 is located at a side far from the cover plate 130.

Further, in an embodiment of the present utility model, the bottom end of the water outlet pipe 140 is connected to the water draining hose 150, and the water draining hose 150 is located near one end of the box 100, so that the residual water in the water outlet pipe 140 can flow back and be drained through the water draining hose 150, and freezing is avoided.

To prevent the case 100 from directly contacting the ground, in an embodiment of the present utility model, the bottom of the case 100 is provided with a base 160.

In order to provide more heat transfer tubes 210, in one embodiment of the present utility model, the through holes 110 are uniformly distributed along the axial direction of the case 100.

Further, in an embodiment of the present utility model, a step 170 is formed on a side of the through hole 110 away from the case 100, and a sealing ring 180 is embedded on the step 170.

In order to allow more uniform heat transfer, in one embodiment of the present utility model, the length of the heat transfer tube 210 is at least three-fourths the height of the housing 100.

Further, in an embodiment of the present utility model, the length of the heat generating tube 220 is at most four fifths of the length of the heat transmitting tube 210, so that heat can be rapidly dissipated through the heat transmitting tube 210.

For maintenance, in one embodiment of the present utility model, the heating tube 220 includes a resistance wire 221 and a grip lever 222, and the resistance wire 221 is disposed around the grip lever 222 along an axial direction.

When the above-mentioned cold water tank is specifically used, the cooling water can be filled through the feed inlet 120, and the heating tube 220 is inserted into the heat transfer tube 210 at a preset outdoor temperature or time, the heat of the heating tube 220 is continuously conducted into the tank body 100 through the heat transfer tube 210, and exchanges heat with the cooling water in the tank body 100, so that the temperature in the tank body 100 is always below the freezing point, and freezing is avoided. The heat transfer tube 210 has smaller volume, occupies smaller volume inside the tank 100, and has no influence on the actual storage of the cooling water in the tank 100. It should be emphasized that when one end of the heat pipe 220 extends into the heat transfer pipe 210 along the through hole 110, the other end of the heat pipe 220 is closed with the through hole 110, so that most of the heat is dissipated only through the heat transfer pipe 210, and the anti-freezing effect is not reduced.

The present utility model is not limited to the above-mentioned embodiments, and any changes or substitutions that can be easily understood by those skilled in the art within the technical scope of the present utility model are intended to be included in the scope of the present utility model.
