Fixed type water chiller capable of recycling waste heat

Abstract

The invention discloses a fixed type water chiller capable of recycling waste heat. The fixed type water chiller comprises a machine shell and a bottom plate, wherein the bottom plate is fixedly connected with the outside ground through a plurality of bolts; a liquid tank is fixedly arranged at the bottom of the bottom plate; a refrigerating machine is fixedly arranged in the machine shell; a cooling liquid outlet pipe, a water inlet pipe, a water outlet pipe and a cooling liquid inlet pipe are arranged in the refrigerating machine respectively; the water outlet pipe is communicated with a material distribution box; the other end of the material distribution box is communicated with a plurality of backflow pipes; the plurality of backflow pipes penetrate through the bottom plate and are communicated with the interior of the liquid tank; and the backflow pipes are connected with a waste heat utilization structure and a cooling recycling structure. The fixed type water chiller has the advantages that a cooling medium and cooling liquid are cooled through an evaporation cooling process of low-boiling-point evaporation liquid and an air cooling process of heat dissipation blades respectively, and the problem that liquid water enters a cooling system is solved, so that the cooling efficiency is improved, the total amount of water in the water circulating flowing process is reduced, and resources are saved.

Description

technical field [0001] The invention relates to the technical field of ice water machines, in particular to a fixed water ice machine for recovery and recycling of waste heat. Background technique [0002] In various industrial production processes, due to machinery, molds and chemical reactions, etc., heat will be generated during work. When the temperature exceeds the tolerance of the material, the product quality will be unstable. Taking plastic products and electroplating products as an example, the cooling time of plastic products accounts for more than 80% of the entire cycle in production. The importance of reducing cooling time can be seen from this. Chilled water can absorb heat in time, so that the temperature of the mold cavity can be quickly lowered, and the speed is accelerated. The product is finalized, the mold opening time is shortened, and the production efficiency is improved. [0003] Among them, the cooling method of the chiller is generally water-cooled...

Problems solved by technology

[0003] Among them, the cooling method of the chiller is generally water-cooled or air-cooled. For the water-cooled chiller, since it uses liquid water as the cooling medium and cooling liquid respectively, so in use, on the one hand, as the cooling medium After the liquid water absorbs the heat of the refrigerant in the cooler, it needs to stand still for a long time before it can be recycled, especially when it is used in hot summer, the cooling time of the cooling medium is longer, and the waste heat energy in it will be wasted. At the same time, the total amount of water required by the cooling medium is extremely large. On the other hand, as the cooling liquid, the temperature before being cooled is relatively high, and the compressor will consume more energy to cool it down, which will affect the efficiency. Based on this, the present invention designs a A fixed ice water machine for waste heat recovery and recycling
