Background

The special hot water unit for bathing is arranged in an equipment room of a bathing place, a large amount of electric control equipment in operation needs to continuously dissipate heat to maintain normal operation, but the environmental influence in the equipment room is quite remarkable. The bath places are generally indoor at high temperature and high humidity, biogas gases are dispersed in the bath sewage, meanwhile, various additives are added into the water purifying equipment and the circulating filtering equipment, the elements are complex in composition, and various conditions are comprehensively combined, so that precise fragile electrical elements are extremely easy to cause oxidation and corrosion, and faults and even equipment shutdown are caused.

The existing solution is to install a forced air refrigeration cycle cooling system, namely, to install a circulating fan for the unit. However, the following disadvantages exist:

firstly, under the condition that forced convection heat exchange is carried out by fan air supply, uneven heat dissipation can occur under the influence of a structure, and some air supply dead angles are easy to occur, so that the heat dissipation effect of all electric devices is inconsistent.

Secondly, although the existing cooling device can maintain positive pressure in the box and does not lead external air to be introduced, condensed water is easy to condense into the electric cabinet when cold air forcedly passes through the fin heat exchanger for cooling, and if leakage occurs in the heat exchanger calandria, refrigerant splashing can be caused, hidden danger is brought to electric control equipment, and electric shock is easy to occur.

Thirdly, use the fan to increase noise, influence equipment operation experience.

Therefore, a new structural solution is proposed to solve the above-mentioned problems.

Detailed Description

Preferred embodiments of the present utility model are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are merely for explaining the technical principles of the present utility model, and are not intended to limit the scope of the present utility model.

Referring to fig. 1-4, the utility model provides a windless cooling electric cabinet, which comprises a cabinet body 4. A cooling pipe 2, a cooling plate 1 and a shield 3 are provided in the case 4. The isolation cover 3 is fixedly and hermetically connected with the inner wall of the box body 4. The cooling pipe 2 and the cooling plate 1 are both arranged in the isolation cover 3. The electronic components 5 in the electric cabinet are mounted on the outer side surface of the isolation cover 3.

The cooling plate 1 is fixedly connected with the box body 4 through bolts and is attached to the cooling pipe 2, and the cooling pipe 2 is pressed on the inner wall of the box body 4. The cooling tube 2 is in a reverse-folded shape and is preferably made of red copper. The cooling plate 1 is a sheet metal part and is provided with a plurality of folding grooves 11, so that the whole cooling plate 1 is corrugated, and each straight pipe section on the cooling pipe 2 is clamped into the folding groove 11.

Both ends of the cooling pipe 2 pass through the box body 4, and when in use, the cooling pipe needs to be connected to a device for circulating a low-temperature medium, and the low-temperature medium flows in the cooling pipe 2, so that the cooling effect is achieved. The device for circulating the low-temperature medium belongs to the prior art, and therefore, the description is omitted.

Because the cooling area of the cooling pipe 2 is limited and cannot be directly and fixedly connected with the wall plate of the box body 4, the cooling plate 1 is pressed against the cooling pipe 2, so that the cooling pipe 2 is fixedly installed, the heat exchange area is increased, and the cooling plate serves as a cooling fin.

The cooling plate 1 is in direct contact with the cooling pipe 2, and the surface thereof is liable to be condensed, so that the insulating cover 3 plays an insulating role. On the one hand, adverse effects of water drops generated by condensation of water vapor on the safety of the electronic components 5 in the cooling process are avoided, and on the other hand, the barrier isolates the cooling tube 2 from the electronic components 5, so that the use of the electronic components 5 is not affected even if the cooling tube 2 leaks. And the electronic components 5 are all installed on the isolation cover 3, and the normal installation of the electronic components 5 is not affected.

The whole scheme has the advantages that:

1. can be cooled in a windless state, does not generate noise and wind feeling, isolates dew condensation and possible leakage, and fully protects the electronic components 5.

2. The water in the heat source water inlet pipeline 6 in the existing bath water supply system is utilized for cooling, so that an independent low-temperature medium does not need to be configured, a power system does not need to be configured for the flowing of the low-temperature medium, and the energy is saved.

3. Because conduction heat exchange and radiation heat exchange are carried out by means of the whole isolation cover 3, the heat exchange is more uniform, dead angles with low heat exchange efficiency do not exist, and even if a machine set is stopped, the cooling pipe 2, the cooling plate 1 and the isolation cover 3 still can keep relatively low temperature in a certain time, so that cooling operation can still be carried out, and the machine set cooling device has advantages compared with an air supply cooling mode.

The utility model also provides a special hot water unit for bathing, which comprises a heat source water inlet pipeline 6 and the airless cooling electric cabinet. The two ends of the cooling tube 2 in the windless cooling electric cabinet are connected with a heat source water inlet pipeline 6, and the inlet of the cooling tube 2 is positioned in the upstream direction of the outlet. In this way, the water in the heat source water inlet line 6 enters the cooling pipe 2 as a low-temperature medium, performs a cooling function, and is discharged back to the heat source water inlet line 6 through the cooling pipe 2. The advantages are that: the first one, the flow of the low-temperature medium in the cooling pipe 2 relies on the power provided by the water pump on the heat source water inlet pipeline 6, so that a power system is not needed to be additionally arranged for the cooling implementation in the scheme. Secondly, water in the existing pipeline is utilized, a circulating cooling medium does not need to be independently arranged, and water in the heat source water inlet pipeline 6 is not lost in the cooling process. Thirdly, the water in the heat source water inlet pipeline 6 is at about 15 ℃, so that the water can play a role in cooling, and meanwhile, the temperature is not too low, and dew condensation is not easy. Fourth, the flowing medium absorbs heat after cooling the electric cabinet, and enters the unit along with the heat source water inlet pipeline 6, so that a certain amount of additional heat source is added to the unit, and the unit capacity is further improved.
