Description

Near-body microenvironment adjusting device

Technical Field

The invention relates to a near body microenvironment adjusting device, in particular to a compact structure device which uses a thermoelectric module, is suitable for automobile seats and office seats and is used for adjusting the near body microenvironment.

Background

A near-body microenvironment conditioner is generally a device that uses a fluid to bring the temperature of some sort of cold or heat source near the skin surface of the human body to change the temperature of the near-body area. At present, directional air conditioners are generally adopted for improving the temperature in a vehicle or an office, so that the ambient temperature around a human body is well improved, and the energy consumption for changing the ambient temperature of the whole space to achieve the same effect is reduced. However, the air conditioner still needs the support of a refrigeration cycle system and an air cycle system, and the air conditioner is inevitably large in size, and the necessary energy consumption is difficult to reduce, so that the recent body microenvironment regulation technology is provided.

At present, the near-body microenvironment adjusting device is divided into a summer ventilating cushion and a winter hot wire cushion by taking a cushion as a carrier. The ventilation cushion passes through the fan, in the gas circuit of cushion is sent into to wind, blows to human surface in the cavity through the cushion surface, takes away the heat, reduces human surface temperature with the mode of forcing the convection current, or adopts the fan, through the cavity on cushion surface, inhales the cushion with the heat that the people gived off, reaches the effect of cooling. Because the cushion only adopts the fan, the cushion does not occupy too large space, and in the air-conditioned compartment, the temperature can be adjusted through the whole space temperature, so the effect of long-time sitting without heat can be achieved. However, the corresponding negative effects brought by such a mechanism are that firstly, only the fan is used for providing wind power, the phenomenon that the buttocks are hot when the vehicle enters the vehicle in summer and the phenomenon that the buttocks are frozen in winter cannot be solved, and because the temperature in the vehicle cabin cannot be changed rapidly, the temperature of the seat cushion cannot be changed rapidly. Secondly, the temperature of the cushion can not be adjusted actively, mainly speaking, under the condition that the wind speed can only be changed, the cold wind which is blown to the skin continuously sometimes can cause discomfort of the human body, but the wind speed is reduced and the temperature of the cushion can not be kept, thus losing the significance of adjusting the temperature.

In order to solve the problems of the ventilated cushion, a near-body microenvironment temperature adjusting device utilizing a thermoelectric module is the best choice. Thermoelectric modules, i.e. peltier modules, also called heat pumps, can be used both for heating and for cooling. When current passes through a loop formed by different conductors, in addition to generating irreversible joule heat, heat absorption and heat release phenomena respectively occur at joints of different conductors along with different current directions. The movement of charge carriers in the conductor creates a current. Since charge carriers are at different energy levels in different materials, excess energy is released as it moves from high to low energy levels; conversely, when moving from a low level to a high level, energy is absorbed from the outside. Energy is absorbed or released as heat at the interface of the two materials. This effect is reversible, with the inversion of the current direction, converting endothermic to exothermic.

Such techniques are now immature. At present, the following difficulties mainly exist: 1) the thermoelectric module is inefficient to use. At present, most of thermoelectric modules adopt air as a flowing medium and are matched with a fan to intake air laterally, but the air blown out by the fan generates uneven speed distribution due to the action of centrifugal force, so that the speed distribution of heat radiating fins passing through the thermoelectric modules is different, the temperature of the heat radiating fins is reduced unevenly, and the efficiency is greatly reduced; 2) the structure occupies too much space. For the efficiency improvement that makes thermoelectric module, can increase the convection heat transfer coefficient at hot junction, cold junction fin installation fan respectively, strengthen the heat transfer, but greatly increased whole device occupation space, make the device show slightly heavy, the usage space is restricted.

In order to rapidly promote the wide application of the thermoelectric module, a small and light thermoelectric temperature-regulating air-conditioning cushion technology has important innovation value.
