A kind of new type low temperature water tank
Technical field
The utility model relates to a kind of refrigeration plant, specifically a kind of new type low temperature water tank.
Background technology
Low temperature water tank is one of conventional refrigeration system equipment, it connects handpiece Water Chilling Units and heat transmission equipment respectively, the structure of now conventional low temperature water tank is the casing of hollow, low temperature water tank and the cold water mix from handpiece Water Chilling Units is entered through the backwater of heat exchange at heat transmission equipment, because through the temperature of the backwater of heat exchange about 12 DEG C, the about 1-3 DEG C of cold water temperature of the water outlet of handpiece Water Chilling Units, therefore through the about 4-7 DEG C of leaving water temperature of cold water low temperature water tank after low temperature water tank mixing of the backwater of heat exchange and the water outlet of handpiece Water Chilling Units, but the leaving water temperature of the working condition requirement low temperature water tank had now is 1-3 DEG C, therefore the structure of existing low temperature water tank cannot meet instructions for use.
Utility model content
In order to overcome the shortcoming that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of new type low temperature water tank, and its leaving water temperature can control at 1-3 DEG C, well meets user demand.
In order to solve the problem, the utility model is by the following technical solutions: a kind of new type low temperature water tank, comprise casing, it is characterized in that, described box house is provided with dividing plate, dividing plate casing is separated into left and right two independently cavity be respectively mixed zone and cold water area, the lower end of dividing plate is provided with the balance pipe being communicated with mixed zone and cold water area, the upper end of cooling water outlet respectively by pipeline connection mixed zone of handpiece Water Chilling Units and the upper end of cold water area, the backwater outlet of the low temperature water tank of the lower end of the backwater entrance of handpiece Water Chilling Units and the mixed zone of low temperature water tank, the cooling water outlet of low temperature water tank is communicated with the lower end of cold water area, the backwater entrance of low temperature water tank is communicated with the upper end of mixed zone, the cold water inlet of heat transmission equipment is communicated with the cooling water outlet of low temperature water tank, the backwater outlet of heat transmission equipment is communicated with the backwater entrance of low temperature water tank.
The beneficial effects of the utility model are:
1, the backwater that the cold water of cold water area does not export with the backwater of heat transmission equipment contacts, and therefore stable in outlet water temperature can control at 1-3 DEG C by the cooling water outlet of low temperature water tank, well meets and uses needs.
2, the backwater of the backwater outlet of heat transmission equipment is in mixed zone and cold water mix, and now the water temperature of backwater reduces, then enters the backwater entrance of handpiece Water Chilling Units by the backwater outlet of low temperature water tank, effectively can improve the operating efficiency of handpiece Water Chilling Units, more energy-conservation.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described further:
Fig. 1 is structural representation of the present utility model;
In figure: 1 handpiece Water Chilling Units, 2 casings, 3 dividing plates, the backwater entrance of 4 low temperature water tanks, 5 heat transmission equipments, 6 cold water area, the cooling water outlet of 7 low temperature water tanks, the backwater outlet of 8 low temperature water tanks, 9 balance pipes, 10 mixed zones.
Detailed description of the invention
As shown in Figure 1, a kind of new type low temperature water tank, comprise casing 2, described casing 2 inside is provided with dividing plate 3, dividing plate 3 casing 2 is separated into left and right two independently cavity be respectively mixed zone 10 and cold water area 6, the lower end of dividing plate 3 is provided with the balance pipe 9 being communicated with mixed zone 10 and cold water area 6, the upper end of cooling water outlet respectively by pipeline connection mixed zone 10 of handpiece Water Chilling Units 1 and the upper end of cold water area 6, the backwater entrance of handpiece Water Chilling Units 1 exports 8 with the backwater of the low temperature water tank of the lower end of the mixed zone of low temperature water tank and is communicated with, the cooling water outlet 7 of low temperature water tank is communicated with the lower end of cold water area 6, the backwater entrance 4 of low temperature water tank is communicated with the upper end of mixed zone 10, the cold water inlet of heat transmission equipment 5 is communicated with the cooling water outlet 7 of low temperature water tank, the backwater outlet of heat transmission equipment 5 is communicated with the backwater entrance 4 of low temperature water tank.
The utility model is not only confined to above-described embodiment.
